Internal Linking 2026+: The Architecture That Lifts a Website in Search

Artyom Dovgopol

Today, internal linking is not just a technique. It’s a way to build a website so that crawlers instantly find the right pages, users never get lost, and the business receives predictable results. When the structure is set up correctly, the site works as a connected system — not a pile of isolated pages.

Key Takeaways 👌

Intro

In 2026, internal linking has become one of the defining ranking factors — and the reasons are obvious.
Google now relies heavily on structural signals: hubs, clusters, and clearly organized thematic trees.
Search algorithms evaluate not isolated pages, but interconnected content systems.
Even medium-sized websites operate under a limited crawl budget — crawlers prioritize pages that are well linked and easy to reach.

Internal PageRank has become the backbone of stable visibility: the way your architecture is built determines what gets indexed and what eventually drops out.
That’s why working on your overall website structure is now a top priority for any business.

Internal linking remains the safest, cleanest way to strengthen important pages without risking penalties or over-optimization.

A well-designed internal link structure delivers clear, measurable benefits:

— deeper and more efficient crawl coverage;
— faster indexation of new and updated pages;
— higher CTR for child pages;
— stronger topical clusters;
— reduced noise from low-value sections;
— more intuitive navigation and better conversions;
— higher stability in competitive niches.

PART 1. Basic Models and Strategy

1. Website Types and Internal Linking Principles

Internal linking isn’t the same across all websites — the strategy depends on architecture, business goals, and the nature of the project.
That’s why in full-scale web development projects, the structure is always planned in advance rather than patched later.

We’ll break down four core models:

1) Small Websites (up to ~100 pages)

For small websites, the main goal is to deliver internal PageRank to commercial pages as quickly as possible: services, case studies, landing pages.
Here, strengthening key landing pages is especially important — one correctly placed link can shift their ranking by several positions.

2) Corporate Websites (100–2,000 pages)

Corporate websites are the most complex architecture type.

Here, structure affects everything:
— how Googlebot moves through nested levels,
— which sections become hubs,
— which pages drag weight downward.

In this model, internal linking becomes almost an engineering task.
When we work on corporate platforms, section hierarchy and internal PageRank routes become the core of architectural planning.

3) Large Content Websites (up to ~15,000 pages)

These websites are built around thematic hubs and topic trees.
Every article should strengthen its hub, and the hub should amplify the entire cluster.
Not only downward links matter — lateral links within the same cluster are just as crucial.

Architectural mistakes here easily lead to thousands of pages “floating” without any ranking weight.

4) Aggregators & Marketplaces (15,000–5,000,000+ pages)

This is the heaviest category in terms of crawl budget and quality control [LINK → /web-development/ecommerce/] and [LINK → /aggregator].

Huge catalogs, millions of item pages, faceted navigation, filters — any structural mistake multiplies across the entire system.

That’s why these projects require carefully designed category architecture and strong cross-linking, similar to advanced e-commerce systems.

2. PageRank, Crawl Budget & Link Graph: The Technical Foundation

Every internal linking system relies on three fundamental mechanisms that determine how Google distributes ranking weight inside a website and which pages receive crawl priority.
These mechanics sit at the core of any internal optimization workflow — including content layout, structure, and On-Page SEO.

2.1. Internal PageRank (IPR)

The classic simplified formula looks like this:
PR(A) = (1 – d) + d × Σ(PR(Bᵢ) / L(Bᵢ))

Where:
A — the target page;
Bᵢ — pages linking to A;
L(Bᵢ) — number of outgoing links on page Bi;
d — damping factor (typically 0.85–0.95 for internal networks).

Practical implications:

— Corporate websites perform best with d = 0.85–0.90.
— Large aggregators require d = 0.92–0.95, otherwise the graph loses weight.
— Pages with 200+ outgoing links sharply drop in significance.

A correctly distributed internal PageRank forms the “structural skeleton” of a website — the foundation that determines which pages remain stable during ranking updates.

2.2. Crawl Budget

Google allocates a limited crawl resource — the Crawl Budget:
— on small websites, the limit roughly equals the page count;
— on medium-sized sites, it depends heavily on link structure quality;
— on large sites, it is driven almost entirely by architecture.

Weak technical zones, poor structure, duplicates, and junk sections “eat” the crawl budget, slow indexation, and push parts of the site out of rotation. This is especially critical for websites requiring strong structural hygiene — a topic that overlaps with the practices described in the article “Website Security: How to Protect Your Web Resource”.

Proper internal linking preserves crawl budget and directs crawlers toward priority nodes: services, hubs, longreads, and commercial pages.

2.3. Semantic Link Graph

Modern ranking algorithms evaluate not just the quantity of links, but also the semantic relationships between pages: topic groups, content clusters, and meaning-based structures.

Google analyzes:
— parent → child relationships;
— hub → group connections;
— cluster membership;
— product → category ties;
— category → brand ties;
— and the most important chain: article → service.

These relationships are not random — they stem from semantic core planning and topic clustering performed during Keyword Research.
Incorrect linking breaks this graph: pages become isolated from their topical groups, crawlers misclassify them, and parts of the content lose rankings.

To avoid this, you must build structure not only around design logic or editorial preferences, but also around search engine logic.
A detailed breakdown of correct architectural principles is given in the guide “How to Create Website Structure Step-by-Step Guide”, which clearly illustrates what strong semantic trees should look like.

3. Internal Linking Strategy by Website Type

Internal linking behaves differently across website types.
Architecture, depth of hierarchy, content volume, and business goals all determine how internal PageRank should be distributed.
Below are four universal models.

TYPE 1: Small Websites (up to 100 pages)

This includes personal websites, small-business sites, and simple business card–style projects.

Core internal linking goals:
— strengthen key commercial pages;
— direct weight from blog → service pages;
— create a closed navigation loop;
— tie informational content to commercial content.

Fundamental Model
“Wheel → Spokes” structure:
Home → Services → Subservices → Articles → Services

Rules:
1) Every service page should receive 10–20 incoming links from articles, other services, the homepage, and hubs. (This also affects budgeting — see the analysis in How Much Does Website Development Cost in 2026).
2) Every blog post must link to a service page. Anchor types: exact, partial, or semantic.
3) Orphan pages are forbidden. A page without incoming links loses up to 45% of its chance to remain indexed.

TYPE 2: Corporate Websites (100–2,000 pages)

Typical examples: digital agencies (including Toimi), manufacturing companies, developers, educational platforms, and franchise networks.

This is the most complex architecture type because it simultaneously contains:
— multi-level hierarchy,
— a large library of informational materials,
— dozens of commercial service pages,
— several hubs and sub-hubs,
— different traffic types and different page roles.

Corporate websites are no longer “business cards.”
They are full-scale ecosystems where architecture, navigation logic, and PageRank distribution between services matter deeply.
That’s why a clean service structure — for example, Corporate Website Development — becomes critically important.

Internal Linking Goals for Corporate Structures
— distribute PageRank between services and their sub-directions;
— strengthen core commercial service pages;
— build informative pyramids around key topics;
— eliminate “junk loops” and dead-end pages;
— ensure deep crawling and continuous reindexation.

Linking Model:
“Service → Cluster → Authority → Hub → Service”
This reflects the practical implementation of Google’s Topical Authority patterns.

Typical chain:
Service → Hub → Sub-hubs → Articles → Recommendations → Service

Key Internal Linking Rules for Corporate Websites

Rule #1. Every service is an independent node with its own clusters
Example from Toimi: the service “Website Development” includes:
— UX/UI (hub),
— SEO (hub),
— Front-end development (technical hub),
— informational article “History of Development,”
— longread “How to Choose an Agency.”
All of these materials must link back to the core service page.

Rule #2. Longreads are the strongest weight donors
They create:
— deep navigation paths,
— high dwell time,
— low bounce rates,
— a strong topical signal.
A longread should link out 3–7 times to services, clusters, and hubs.

Rule #3. Home → hubs → services (not the other way around)
Common mistake:
Home → services → hubs → articles

Correct logic:
Home → hubs → services → articles → services

Rule #4. Every article must contain at least 3 internal links
— one to the service page,
— one to the hub,
— one to a neighbor article within the same cluster.

Example of a Corporate Site Structure

TYPE 3: Content Websites (up to ~15,000 pages)

Content websites include media outlets, educational platforms, expert blogs, informational directories, and any project where content volume grows in branching structures.
Their primary challenge is topical purity — maintaining strong, clearly defined clusters that Google can confidently interpret.

The core purpose of internal linking here is to build thematic hubs and sub-hubs, create a “tree of meaning,” and preserve stable topical weight within every direction.

Strategy:
“Topic → Subtopic → Articles → Article Web”

Main principle:
Every topic is a tree, not a linear chain.

Components of a cluster:
— Hub (main topic page)
— Sub-hubs (groups within the topic)
— Core articles
— Satellite articles
— Sibling links (horizontal relationships between related articles)

At this stage, it’s crucial to remember that a content tree is not created manually — it is built from semantic data.

Which is why we must mention:
Keyword Research → the foundation for building topical clusters

Optimal Model (for both Google Discover + SEO)

Linking Requirements for Every Article in the Cluster

Each article must contain:
— 2 links upward (to sub-hub → hub)
— 1 link to the main cluster article
— 3 horizontal sibling links to related materials
—1 link downward to a deeper article or FAQ
This creates an actual Article Web, not a linear content chain — and this distinction is critical for building Topic Authority.

Typical Mistake (90% of content websites)
Hub → Article 1 → Article 2 → Article 3

This structure kills:
— PageRank
— Crawl depth
— Topical weight
— Discover signals

Correct Graph-Based Structure

Inside each sub-cluster, articles are interlinked horizontally.
This forms strong Topic Authority, preserves static PageRank inside the cluster tree, and increases the number of organic entry points.

TYPE 4: Aggregators & Marketplaces (50,000 – 5,000,000 pages)

This is the top tier of internal linking.
In aggregators, 80% of SEO = internal architecture, because scale changes everything:
— crawl depth
— indexation quality
— PageRank redistribution
— crawler trajectories
— strict crawl budget limits

Core Internal Linking Tasks for Aggregators
— optimize category hierarchy;
— distribute PageRank across deep nodes;
— control duplicate generation;
— eliminate endless internal loops;
— strengthen high-value commercial categories;
— ensure instant re-indexation of new listings.

Because this category directly overlaps with marketplaces and large e-commerce, this is where the eCommerce Development approach becomes relevant, and the Aggregator Development model applies.

Model:
“Hierarchy → Facets → Listings → Backlinks → Loops”
Let’s break each component down.

Component 1: Category Hierarchy

The main donors of weight in any aggregator are categories.

Correct model:

Categories:
— strengthen subcategories;
— pass PageRank down to listings;
— receive links from filters and articles.

Component 2: Faceted Navigation

This is the most dangerous element of large websites.
If misconfigured, it generates millions of duplicates.

Correct rules:
— index only a whitelist of facets;
— use nofollow/noindex on secondary filters;
— canonicalize to the main listing version;
— block parameter URLs via robots;
— link internally only to allowed facets.

Component 3: Listings

These are product or offer pages.
Goals:
— send weight upward → to categories;
— receive weight downward → from other listings.

Internal linking elements for listings:
— “Similar products” block;
— “Frequently viewed together”;
— “Category” block;
— “Filter” block;
— “Brands” block.

Component 4: Backlink Redistribution

External backlinks usually hit:
— the homepage,
— categories,
— popular products.
Your job: use internal linking to push their weight downward through the tree.

Component 5: Anti-Loop Architecture

You must completely avoid loops like:
Listing → Similar → Similar → Similar → …
Google wastes crawl budget, and you gain nothing.

Model of an Aggregator

4. Fourteen Fundamental Internal Linking Rules

1) No orphan pages — every page must have incoming links.

2) Parent → child → sibling — the core principle.

3) PageRank concentration — important pages receive more links.

4) Longreads are the strongest donors of weight.

5) Horizontal links strengthen topical relevance.

6) Vertical links create structural authority.

7) Service pages receive weight from content — not the other way around.

8) Facet pages are indexed selectively.

9) No more than 200 outgoing links per page.

10) Homepage → hubs (not everything at once).

11) Menu links are indexable but weak in PageRank flow.

12) Footer links work only on large websites.

13) 404s, archives, pagination — always controlled by PR budget.

14) New pages must strengthen the structure, not break it.

PART 2. Google Algorithms, Formulas, Graph Modeling & Internal Architecture

5. How Google Actually Evaluates Internal Links in 2026+

The SEO industry still clings to myths like “Google ignores internal links” or “internal linking doesn’t matter.”
This is false.
From 2022–2026+ Google has been actively using:
— Updated PageRank
— Inverse Document Frequency Graph
— Topic-Sensitive PageRank
— Contextual Link Relevance
— Semantic Attention Maps
— Link Distance Scoring
— Crawl Efficiency Algorithms
— Site-Level Authority Redistribution
Let’s break these down.

5.1. Updated PageRank Inside Websites

Google never disabled PageRank — it was absorbed into RankBrain, Neural Matching, Hummingbird, BERT, and MUM.

Internal PageRank takes into account:
— number of outgoing links;
— depth of hierarchy;
— link type (navigation, content, system);
— the context of the text block;
— semantic proximity between documents.

Simplified formula (a model close to real behavior):
IPR(A) = (1 − d) + d × Σ[(PR(Bᵢ) / Out(Bᵢ)) × W(Bᵢ → A)]

Where W is contextual relevance weight:
W = α·semantics + β·link position + γ·block type + δ·anchor quality

With typical coefficients:
α (0.4–0.6) — topical relevance
β (0.1–0.2) — visual position (higher = more weight)
γ (0.2–0.3) — block type (content > navigation > footer)
δ (0.05–0.1) — anchor type (natural > partial > forced)

5.2. Topic-Sensitive PageRank

A critical algorithm for large websites.
Google identifies the topic of each page and redistributes PageRank based on topical affinity.

Practical result:
— a link within the same cluster carries ×3–6 weight;
— a link between distant clusters has ×0.2–0.4 weight;
— hubs strongly reinforce their own children, but barely affect unrelated sections.

5.3. Contextual Link Relevance (CLR)

Google evaluates:
— the surrounding text of the link;
— the semantic purpose of the paragraph;
— presence of LSI terms;
— semantic embeddings.

Practical outcome:
— a link inside a “weak” paragraph → −40% weight;
— a link inside a “see also” list → −20–50% weight;
— a link inside a meaningful core paragraph → maximum weight.

5.4. Link Distance Scoring

The algorithm measures how far pages are from one another.

Distance = number of click steps

Impact:
— 1–2 clicks → strong semantic signal
— 3–4 clicks → weak
— 5+ clicks → relationship nearly lost

Conclusion:
Depth should remain ≤3 clicks from the homepage.
This is covered in detail in our Step-by-Step Website Development Guide.

5.5. Site-Level Authority Redistribution

Google recalculates a website’s domain authority and redistributes it internally based on:
— hub strength;
— number of articles in a cluster;
— page-level trust;
— types of internal links.

Websites without hubs lose 40–70% of potential internal weight.

6. Modeling the Link Graph: How to Build an Internal Linking Structure Correctly

Graph modeling is the core skill of a website architect.
Most SEO specialists never do it — which is why their results stay weak.

6.1. Main Types of Internal Link Graphs

1) Tree Structure

Used for:
— small websites,
— corporate websites.

Pros: simplicity.
Cons: weak horizontal connectivity.

2) Hub Graph

Used for:
— corporate websites,
— content websites.

Pros: strong topical distribution.
Cons: requires proper architecture.

3) Cluster Graph

Used for:
— media portals,
— educational platforms,
— informational sites.

Pros: maximum topical authority.
Cons: difficult to maintain at scale.

4) Facet Graph

Used for:
— aggregators,
— marketplaces.

Pros: highly scalable.
Cons: very high risk of duplicate explosions.

6.2. Correct PageRank Distribution Structure

Ideally, the internal link graph should follow a three-level model:
Level 1 — Homepage / Root Hubs
Level 2 — Categories / Services / Topics
Level 3 — Articles / Listings / Product Cards

And between levels:
— V2 → V1 — upward reinforcement
— V3 → V2 — downward distribution
— V3 ↔ V3 — horizontal connections
— V2 ↔ V2 — cross-topic connectivity
This ensures a balanced, stable PageRank flow.

6.3. Example of a Non-Trivial Ideal Model 

Each article contains:
— 1 upward link to its parent,
— 1 link to the hub,
— 2–5 sibling links to neighboring content.

7. Link Sculpting 2026+: Modern Methodology for Controlling Internal PageRank

Link Sculpting = controlled redistribution of internal PageRank.
This methodology allows you to:
— strengthen commercial pages;
— reduce the influence of low-value sections;
— control crawl depth;
— shape clear topical signals.

7.1. Where Link Sculpting Works Best

— Corporate websites
— Content-driven media
— Marketplaces (with constraints)

7.2. Link Sculpting Methods

Let’s break down the methods that have real practical value.

Method 1: PR Concentration

We deliberately direct more internal weight to:
— service pages,
— categories,
— hubs,
— high-value landing pages

How:
— Longreads → 3–7 links to services
— Case studies → 2–3 links
— Blog posts → 1–2 links
— Hubs → 5–15 links

Method 2: Cutting Off Junk Pages

Using:
— noindex
— robots.txt
— canonical
— removal of cross-site links

Pages that must be “turned off”:
— tag archives
— sorting pages
— infinite pagination
— faceted filters
— technical system pages

Method 3: The “Power Triangle” Effect

Model:
Hub → Service → Hub → Article → Service

This trajectory creates:
— topical reinforcement
— improved relevance
— a stronger PR flow

Method 4: Weight Pumping

Used when:
— a service must reach the top;
— there is a large library of informational content.

Technique:
— Select 20–50 articles.
— Adjust their internal link structure.
— Strengthen the target commercial page with 2–4 links from each article.

Method 5: PR Isolation for Weak Sections

Weak sections reduce the overall authority of the site.
They must be:
— not indexed,
— not linked internally,
— not included in navigation menus.

7.3. What You Absolutely Must NOT Do
❌ Random linking — links without logic
❌ Over-anchoring — 100% exact-match anchors
❌ Infinite loops — circular paths with no exit
❌ Sitewide links without weight evaluation
❌ Hidden links
❌ Copying competitor structures blindly

8. Internal Anchor Strategy

Internal anchor strategy is its own discipline.
Google now:
— interprets the meaning of the anchor,
— evaluates diversity,
— analyzes context,
— understands overspam patterns.

8.1. Types of Internal Anchors

8.2. Optimal Distribution

For Corporate Websites:
— Exact: 20–30%
— Partial: 40–50%
— Semantic: 20–30%
— Branded: 5–10%
— URL: 0–5%

For Large Content Websites:
— Semantic: 60–80%
— Partial: 20–30%
— Exact: ≤10%

For Marketplaces:
— Semantic: 60–70%
— Faceted: 20–30%
— Exact: ≤5%

9. Hub & Cluster Architecture: How to Build It Correctly

A hub is a page that:
— unifies a topic,
— strengthens all child pages,
— accumulates and redistributes PageRank.

9.1. What an Ideal Hub Should Contain

A strong hub page includes:
— a clear description of the topic,
— links to sub-hubs,
— links to key articles,
— a list of recommended materials,
— cross-cluster connections (where relevant).
This creates both topical depth and inter-topic context — the two foundations of cluster-based architecture.

9.2. Example of a Hub

PART 3. Practical Internal Linking Schemes

10. Internal Linking for Corporate Websites

(using Toimi’s architecture as the reference model)

A corporate website is a mix of:
— commercial service pages,
— hubs,
— informational content,
— case studies,
— presentations,
— a blog.

This is fundamentally different from:
— content websites (where ~90% = articles),
— marketplaces (where ~90% = listings).

10.1. The Main Mistake Corporate Sites Make:

No Vertical OR Horizontal Graph
A typical (wrong) structure:
Home → Services → Articles → Services

This linear model is weak.
Google cannot correctly detect:
— topical clusters,
— hubs,
— relationships between services,
— relationships between case studies,
— connections between services and articles.

10.2. The Correct Corporate Graph (Universal Model)

10.3. How to Interlink Hubs

A hub (e.g., “Web Development”) must include:
— a link to every service in the cluster,
— links to key articles,
— links to important longreads,
— links to related case studies,
— 1–2 links to adjacent hubs.

Example anchor block inside a hub:
→ Corporate Website Development
→ UX/UI Design
→ SEO Architecture
→ Frontend / Backend
→ Development Case Studies
→ Guide: How to Design a Website for SEO

10.4. How to Interlink Service Pages

Every service page must have:

1) Incoming links from:
— the hub,
— sub-hub,
— 5–20 articles,
— 2–5 case studies,
— 1–2 presentations.

2) Outgoing links to:
— related services,
— the blog,
— case studies,
— the hub,
— FAQ,
— guides & longreads.

10.5. Interlinking Case Studies

Main rule:
Every case study must strengthen the service page.

Minimum linking set:
— Service → Case → Service
— Hub → Case
— Article → Case
Case studies should also interlink with related cases.

10.6. Interlinking Info Content (Blog)

Every article must contain:
— 1–2 links to a service,
— 1 link to the hub,
— 1 link to a longread,
— 2–5 links to related articles.

10.7. Longreads Are the Strongest Weight Donors

Longreads (including this one) must:
— strengthen service pages,
— strengthen hubs,
— create horizontal connections,
— consolidate user traffic.

A longread should contain 7–12 outgoing links:
— 3–5 to services
— 1–3 to hubs
— 3–4 to articles
— 1–2 to case studies

11. Internal Linking for Blogs With 2,000–10,000 Articles

At this scale, clustering becomes mandatory.
Without clusters, internal linking turns into chaos.

11.1. Cluster-Based Architecture

All articles must be organized by:
— 3 topical levels,
— a branching subtopic tree,
— hubs,
— a central (pillar) article for each cluster.

Example:

11.2. Intra-Cluster Linking

Each article must link to:
— the parent hub,
— sibling articles,
— the central pillar article of the cluster.

Model:

11.3. Inter-Cluster Linking Rules

Direct connections between distant topics are forbidden:
❌ SEO → SMM
❌ Branding → Semantics

Allowed:
✔ SEO → UX (related topics)
✔ Development → SEO
✔ Content → Development
Only logical thematic bridges should exist.

11.4. Universal Link Distribution Formula (Per Article)

Each article should contain:
— 1 link upward (to the hub)
— 1 link to the pillar article
— 2–3 links to stable, evergreen articles
— 1–2 links to related (“adjacent”) articles

11.5. The Biggest Mistake: “Dynamic Blocks”

Most websites use automatically generated blocks:
— “Related articles”
— “Popular”
— “Latest”
These drain PageRank into random pages.

Solution:
— manually curated static blocks,
— thematic selections,
— curated lists.

12. Internal Linking for City Pages (Geo Sites & Regional Logic)

Used on:
— service websites,
— regional projects,
— franchise networks,
— catalogs and directories.

12.1. Structure of a City Cluster

/city/
    /service/
        /local-case/
        /local-landing/

This creates a clean regional hierarchy where each level reinforces the one above it.

12.2. How to Link City Pages Correctly

1) Homepage → countries → cities

2) Cities → services

3) Services → cities

4) Local case studies → services

5) Local articles → services

This keeps PageRank inside the correct geographic silo and prevents cross-region noise.

12.3. Interlinking Table for City Pages

13. Internal Linking for Case Studies: Engineering Model

Case studies are a page type that:
— strengthens E-E-A-T,
— influences conversion and sales,
— passes weight directly to service pages.

13.1. Case Study Linking Scheme

— Service → Case
— Hub → Case
— Case → Service
— Case → Related Cases
— Case → Longread
— Article → Case
This turns every case into a PageRank amplifier instead of a dead-end.

13.2. Minimum Internal Link Set for Each Case Study

Every case must include:
— 1–2 upward links (to service pages)
— 1 link to the process page
— 1 link to a related case
— 1 link to an article
— 1 link to the hub

14. International Locales: Linking Between /en /es /pt /ru

Most websites make a critical mistake:
❌ sitewide internal linking between languages

Google interprets this as:
— mixed indexing,
— reduced relevance,
— loss of PageRank.

14.1. Correct Logic

1) Use rel="alternate" + hreflang"

2) Keep all internal links within the same language only

3) Break the PR flow between locales

4) Hubs must be unique for each language version

14.2. Toimi’s Model for International Locales

/en/  
   /services/  
   /cases/  
   /blog/  
/es/  
   /servicios/  
   /casos/  
   /blog/  
/pt/  
   /servicos/  
   /cases/  
/ru/  
   /услуги/  
   /кейсы/

No cross-language internal links.
Each locale is an independent ecosystem.

15. Internal Linking for PDFs, Presentations, HTML Landing Pages & Video

Google indexes:
— PDFs
— HTML presentations
— Google Docs
— YouTube videos
and all of these assets can strengthen your core pages when linked correctly.

15.1. Proper Approach to PDFs

A PDF should:
— include links to service pages,
— be hosted on your domain,
— use a human-readable URL,
— be part of a hub or topical cluster.

Example:
 /media/web-development-guide.pdf

PDFs act as static, high-authority documents — and Google treats the links inside them almost like links in regular HTML content.

15.2. Internal Linking in HTML Presentations

HTML presentations are extremely powerful for SEO.
They should:
— link to service pages,
— link to hubs,
— be connected through the blog (e.g., “related materials” sections).
Because they are HTML-based, they pass internal PageRank exactly like standard pages.

15.3. YouTube → Website Linking

One of the strongest content chains:
Video → Longread → Hub → Service

Inside the YouTube video environment, always use:
— links in the description,
— clickable annotations,
— a pinned comment with the primary link.
This creates a high-authority external → internal flow that amplifies the longread and, through it, the entire cluster.

16. Toimi.pro Internal Linking Standard

(Universal + Scalable)

This block is a real technical document meant for SEO specialists, content editors, developers, and project managers.
It defines how Toimi’s internal linking must work at scale.

16.1. Toimi: Global Structural Map

Key sections:
— Homepage
— Services
— Hubs
— Case Studies
— Blog
— Longreads
— PDF Presentations
— City Pages (optional)
— International Locales
This structure is the foundation for all navigation and PageRank distribution.

16.2. Homepage: Internal Linking Rules

Homepage → hubs (mandatory)
This is the primary vector of PageRank flow.

Forbidden:
❌ Direct links from the homepage to all service pages — this dilutes PageRank and weakens the structure.

16.3. Toimi Hubs: Internal Linking Rules

Each hub must include:
— 4–10 links to services within the cluster
— 3–5 links to relevant case studies
— 2–3 links to longreads
— 5–7 links to important blog articles
— 1–2 links to adjacent hubs

Example for the “Development” hub:
— Corporate Websites
— SaaS Development
— UX/UI Design
— Backend / Frontend
— Case Studies: Taskee, Kirillitsa
— Longread: Website Architecture for SEO
— Articles: structure, prototyping, SEO components

16.4. Service Pages: Link Architecture

Service pages are the most important commercial pages at Toimi.
They must be strengthened systematically.

Required Incoming Links:
— 1 link from the hub
— 1 link from the sub-hub
— 5–20 links from blog articles
— 2–5 links from case studies
— 1–2 links from longreads
— 1 link from a presentation

Required Outgoing Links:
— the hub
— 2–4 blog articles
— 1–2 case studies
— FAQ
— longread or guide
— 2 related services (graph consistency)

16.5. Case Studies: Toimi Linking Standard

1) Case → Service pages: 
— at least 2 links
— different anchor types

2) Case → Case:
— minimum 1 link (related works)

3) Case → Blog:
— minimum 1 article

4) Case → Hub:
— 1 mandatory link
Case studies must amplify the commercial cluster, not exist in isolation.

16.6. Toimi Blog: Strict Linking Structure

Each blog article must contain:
— 1 upward link to the hub
— 1 link to a service page
— 1 link to a longread
— 2–5 links to other articles
— 1 link to a case study
No random linking. No automatically generated “related posts.”

16.7. Toimi Longreads — Primary Weight Donors

Longreads deliver:
— high content volume,
— many linking opportunities,
— strong topical signals.

A longread must include 7–12 outgoing links:
— 3–5 to services
— 2–3 to hubs
— 2–3 to articles
— 1–3 to case studies
Longreads must also interlink with other longreads, forming a high-authority layer.

17. Internal Linking Standard for Taskee.pro

SaaS architecture differs dramatically from corporate websites — the linking logic, page roles, and conversion flows are not the same. Taskee follows a streamlined, product-driven architecture.

17.1. Core Structure of Taskee

— Homepage
— Features
— Integrations
— Blog
— Pricing
— Onboarding pages
— Use Cases
— Support / FAQ
This is the backbone of the product website.

17.2. Homepage → Features (Main PR Flow)

All PageRank from the homepage must flow into the product feature cluster.

17.3. Features → Blog → Features

Each feature page must have:

1) Incoming links from the blog
Minimum 10 links with anchors like:
— time tracking
— task manager
— kanban
— productivity tools
— time management
(multilingual anchors reflect Taskee’s global audience)

2) Outgoing links
— 3 neighboring features
— pricing
— onboarding
— 3–5 blog articles
— 1–2 use cases
— FAQ

17.4. Use Cases → Features → Pricing

Every use case must:
— link to 2–3 features,
— link to pricing,
— have at least 1 incoming link from a blog article,
— have at least 1 incoming link from the homepage.

This builds a clear conversion path:
Use Case → Feature → Pricing → Sign-up

17.5. Taskee Blog: Strict Linking Structure

Each article must contain:
— 1 link to a feature
— 1 link to pricing
— 2–4 links to other articles
— 1 link to a use case

No random linking.
No automatic “related posts.”
All links must reinforce product understanding and conversion pathways.

18. Algorithm for Adding New Pages (Universal Model)

Every new page must go through a strict linking procedure.

Step 1. Determine the Cluster of Belonging

Each new page belongs to a:
— service,
— topic,
— subcluster,
— hub.
This defines its PageRank “home.”

Step 2. Add 2 Vertical Links Upward

Examples:
— Article → Sub-hub
— Article → Hub

Step 3. Add 3–5 Horizontal Links

Sibling connections:
A1 ↔ A2 ↔ A3 ↔ A4 ↔ A5
This builds lateral structure and topical density.

Step 4. Add 1–2 Downward Links (if relevant)

Examples:
— Hub → Article
— Service → FAQ
— Longread → Section of the longread

Step 5. Add 1 Link to a Key Service Page

This is the main monetization anchor for Toimi/Taskee content.

Step 6. Add a Link to a Case Study

Only if the thematic connection is strong.

Step 7. Check Anchor Usage Rules

— Exact: ≤ 20–30%
— Partial: 40–50%
— Semantic: 20–30%

19. Internal Linking Automation (Engineering Level)

Internal linking can be automated — but only when done with strict rules and controlled logic.

19.1. Auto-Blocks

Types of static blocks:
— “Related materials” (STATIC, not dynamic)
— “Frequently read”
— “Topic-related materials”
— “Guide sections”
— “Related services”
Static blocks preserve the structure and keep PageRank flow predictable.

19.2. API-Based Link Generation

For websites with 5,000+ pages, create an internal API, e.g.:
/related/?id=123

The API:
— returns a list of manually assigned links specified by SEO,
— ensures editors cannot break the internal link graph,
— maintains strict control over clusters and hubs.

19.3. Auto-Generation of Hubs

Large sites can automatically generate:
— hubs by tags,
— hubs by categories,
— hubs by word frequency.
This helps scale topical architecture without manual overhead.

PART 5. Fully Patched Internal Linking Architecture for Toimi.pro

A complete, standards-controlled technical document for developers, SEO specialists, editors, PMs, and leadership.

Structure of this section:
— High-level site map
— Hub architecture
— Service architecture
— Case architecture
— Blog architecture
— Longread architecture
— PDF / HTML presentation architecture
— Graph maps — global and detailed
— Ready-to-implement rules for developers
— Linking schemes for “when new content is added”

1. High-Level Map of Toimi

This is the core structural canvas for all internal linking, content growth, and hub architecture.

2. Hub Architecture (Toimi Technical Standard)

Each hub must:
— Collect topical PageRank,
— Distribute it downward (to service pages),
— Connect horizontally (related hubs),
— Connect to the blog,
— Connect to case studies,
— Connect to longreads.

Required components of every hub:
— Title (SEO-focused),
— 4–10 links to services,
— 3–5 links to key blog articles,
— 2–3 links to case studies,
— 2 links to longreads,
— 1–2 links to related hubs

Hubs form the “navigation spine” and determine how Google understands topical structure.

3. Toimi Service Architecture (Technical Regulation)

Service pages are the commercial core of the entire PR system.
Each service page must have 25–40 incoming links.

Incoming links (required):
— Hub → Service (1)
— Sub-hub → Service (1)
— Articles → Service (10–20)
— Case studies → Service (2–5)
— Longreads → Service (3–5)
— PDF → Service (1)
— Presentations → Service (1)

Outgoing links (required):
— Service → Hub
— Service → 2–4 articles
— Service → 1–3 case studies
— Service → longread
— Service → FAQ
— Service → 2 adjacent services
Service pages must unify all commercial signals and route PageRank across the cluster.

4. Case Architecture (Toimi Standard)

Case studies are E-E-A-T distribution points.
Every case must form a PR loop:
— Service → Case → Service
— Hub → Case → Hub
— Articles → Case
— Longread → Case

Minimum internal link set inside each case:
— 1–2 links to services
— 1 link to the hub
— 1 link to an article
— 1 link to a related case
Cases cannot exist as isolated pages — they must reinforce the commercial tree.

5. Blog Architecture (Future 2k+ Articles)

Every article must include:
↑ 1 link to the hub
↑ 1 link to a service
↔ 2–5 links to sibling articles
→ 1 link to a case study
→ 1 link to a longread

Forbidden:
❌ dynamic “related posts” blocks
❌ random linking
❌ auto-generated lists in article bodies
The blog must follow strict, consistent structural logic.

6. Longread Architecture

Longreads are the primary PageRank donors.
Each longread must include:
— 3–5 links to services
— 2–4 links to hubs
— 3–6 links to articles
— 1–3 links to case studies
Longreads should also interlink with other longreads to create a high-authority layer.

7. Architecture for PDFs / HTML Presentations

PDFs must:
— include links to services,
— use clean, readable URLs,
— be hosted locally,
— appear inside relevant hubs.

HTML presentations must include:
→ Services
→ Hubs
→ Case studies
→ Longreads
These assets pass weight and must be integrated into the internal linking system, not left isolated.

Here is the adapted English version — clear, structured, and consistent with your full technical document.
This block requires no internal-link triggers from your list, so it stays link-clean.

8. Graphs: Complete Internal Model of Toimi

These graphs visualize the internal linking architecture: how hubs, services, cases, longreads, and blog articles interconnect into a single PageRank ecosystem.

8.1. Global Model

This is the high-level overview of Toimi’s internal PR flow.

8.2. Graph for the “web” Hub

This hub aggregates PageRank and distributes it among services, case studies, key blog articles, and longreads.

8.3. Service Graph (Example)

/services/web-development
↑  ←  /hubs/web
↑  ←  20+ articles
↑  ←  case studies
↔  UX/UI service
↔  SEO-architecture service
→  2–4 articles
→  case studies
This visualizes both inbound and outbound PR flow for a core commercial service.

9. Ready-to-Implement Rules for Developers

Developers must ensure:
Article template → includes 5 mandatory internal linking blocks
Service template → includes 3 blocks
Hub template → includes 4 blocks
Case study template → includes 4 blocks

And:
— manual control of internal links must be possible;
— API-based generation for “related materials” must be supported;
— HTML links must use standard “a href”;
— no JS-injected links;
— avoid “div onclick” link substitutes;
— avoid JS redirects for internal URLs.
These rules preserve PageRank flow, link clarity, and crawler accessibility.

10. Algorithm for Creating New Content

Every piece of new content must follow a 7-step linking protocol:

Determine the cluster → hub → service the page belongs to

1) Add 2 upward links

2) Add 3–5 horizontal links

3) Add 1 downward link (if relevant)

4) Add 1 link to a service page

5) Add 1 link to a case study

6) Verify the anchor matrix (exact/partial/semantic ratios)

This ensures every new page strengthens the cluster instead of weakening it.
If more content remains — send the next block.

PART 6. Engineering Manual for Internal Linking in Aggregators & Marketplaces

(50,000 – 5,000,000+ pages)

This chapter is a professional blueprint at senior+ SEO-engineering level.
It can be used to build or scale any type of aggregator:
— product marketplaces (Ozon, WB, Kaspi),
— service aggregators (Avito, Profi),
— real estate catalogs (DomClick, CIAN),
— job aggregators (Jooble, HH),
— auto, travel, restaurant, and classified platforms.

Primary goal:

Maximize indexability, crawling efficiency, structural PageRank, and topical relevance — while minimizing duplicates and crawl budget leakage.

1. Base Structure of Any Aggregator

This structure is the foundation for controlled PageRank flow and scalable indexing.

2. Core Technical Tasks of Internal Linking in Aggregators

Aggregators ≠ normal websites.

Internal linking here must solve problems that backlinks, content, and manual work cannot fix:

1) Crawl Budget Management
Google “chokes” quickly on large sites.

2) PageRank Flow Control
Aggregators generate thousands of low-value pages.

3) Topical Weight Preservation
Categories and subcategories must rank for competitive keywords.

4) Facet (Filter) Management
Improper faceting creates millions of duplicates.

5) Managing Giant Link Graphs
Aggregators have millions of nodes — mistakes cost millions of lost pages.

3. Core Formula for Aggregator Internal Architecture

The internal graph must be:
Hierarchical → Controlled → Limited → Targeted → Topically Dense

Forbidden:
❌ endless chains of “similar products”
❌ cyclic recommendation algorithms
❌ auto-generated links without upper limits
❌ random “related” blocks
❌ navigation that creates 10,000+ URL variations

4. The Foundation: Correct Hierarchy for Weight Distribution

Correct Structure (Levels 1–4)
Level 1 — Homepage
Level 2 — Categories
Level 3 — Subcategories / Brands
Level 4 — Listings (products)

PageRank Distribution Logic:
— Homepage → gives 40–55% of total weight
— Categories → receive 10–20%
— Subcategories → receive 5–10%
— Listings → receive 0.01–0.5%
Important:
Listings must NOT compete with categories in SERP.

5. Internal Linking Rules for Each Level

5.1. Homepage → Categories

Homepage must link only to:
— top categories,
— several branded hubs,
— 0 links to listings.

Recommended link count: 20–60
— Too few → PR resistance (↓)
— Too many → PR dilution (↑)

5.2. Categories → Subcategories

Each category must:
— link to 100% of subcategories (if ≤100),
— use static, not dynamic lists,
— include up to 3 guide articles.
Forbidden:
❌ outputting all sub-tags or filters (creates thousands of duplicates)

5.3. Subcategories → Listings

Correct logic:
A subcategory should link only to the first N listings, where N is a strict limit.

Recommended N:
— E-commerce: 40–80
— Real Estate: 50–120
— Auto: 20–60
— Services: 10–40

Why limit matters:
— pages with 500–10,000 listings → PR is spread too thin
— crawl budget is wasted
— Google never indexes depth
— category rankings drop

5.4. Listing → Upward Links

Each listing must pass weight up:
— Listing → Subcategory
— Listing → Category

Additional linking:
Listing → Similar products (strictly limited)

Recommended “similar” limits:
— E-commerce: 4–8
— Real estate: 6–12
— Auto: 6–10
— Services: 4–8

Forbidden:
❌ related=20+
❌ infinite carousels
❌ unlimited auto-generated related blocks

6. Faceted Navigation (Filters) — The Most Dangerous Part of Any Aggregator

6.1. Why Facets Destroy the Graph

Every filter generates a new URL:
/sneakers?color=white  
/sneakers?color=white&brand=nike  
/sneakers?color=white&brand=nike&size=43  
/sneakers?color=white&brand=nike&size=43&season=summer

This results in:
— millions of duplicates
— 99.99% low-value pages
— exhausted Crawl Budget
— PR dilution across categories
— weight leakage into empty queries
— massive keyword cannibalization
Facets are the #1 reason why aggregators collapse under their own size.

6.2. Facet Whitelist

The only correct approach:
Index only the filters that have real search demand.

Example (allowed):
/sneakers/men/  
/sneakers/winter/  
/sneakers/nike/

Never index:
❌ size
❌ color
❌ material
❌ price
❌ availability
❌ sale=true
❌ sort=asc/desc
Almost all UI filters must stay non-indexable, even if useful for the user.

6.3. Limited Internal Linking for Facets

Only whitelisted facets are allowed in internal linking.
Correct model:
Category → Subcategory → Facet (indexable)
Subcategory → Facet (indexable)
Facet → Subcategory

Forbidden:
❌ Listing → Facet
❌ Facet → Facet
❌ Facet → Sorting pages
This prevents recursive graphs and infinite URL multiplication.

7. Crawl Budget Optimization (Core Section of This Manual)

Google crawls NOT the whole site, but specifically:
— pages with incoming links
— pages close to the root
— high-PR nodes
— frequently updated sections
— indexable facets
— hubs
— categories
This must guide your architecture decisions.

7.1. Optimal Crawl Allocation Formula

For aggregators, the optimal distribution:
— 80% → key categories + subcategories
— 10% → listings
— 5% → facets
— 5% → technical/system pages

If listings receive 30–50%+ of crawls:
 → categories drop from top positions
 → subcategories lose relevance
 → overall structure collapses

8. Internal Linking Architecture for Aggregators (Graphs)

8.1. High-Level Graph

This is the core PR spine of a scalable aggregator.

8.2. Facet Graph (Whitelist-Based)

Listings → only link upward
Nothing else should interlink.

8.3. Similar Listings Graph

Strict limit: 4–8 links
No auto-generated carousels without caps.

9. Linking Informational Content in Aggregators

Informational articles must reinforce categories and subcategories.

Every article must link to:
— Category
— Subcategory
— Summary / overview material
— Top listing (editorially selected)
This ensures that informational content directly strengthens commercial taxonomy pages.

10. Linking Seller / Company Pages

If the aggregator contains seller or company profile pages, use the following hierarchical flow:
Seller → Category → Subcategory → Seller’s Listings
This creates a clean upward/downward PR loop and prevents isolation of seller pages.

11. Brand Page Linking

Brand pages are high-authority nodes and deserve a dedicated structure.
Correct linking model:
— Category → Brand
— Brand → Brand listings
— Brand → Subcategory (optional, if relevant)
— Listing → Brand
Brand pages often capture strong branded search demand, so their PR flow must be clean and controlled.

12. Control of Cycles and Infinite Loops

Rule:
Zero infinite recommendation loops.

Typical mistake:
A → B → C → D → A → ...
This wastes crawl budget, inflates the graph, and prevents stable indexing.

All recommendation algorithms must have strict caps, no recursion, and no mutual linking beyond predefined rules.
