High-converting landing page development
in Westwood

The one part of a landing page that has to work without excuses is the form. It is often the part that gets the least design attention. The headline gets tested. The hero image gets chosen carefully. The form at the bottom is dropped in with default settings and left alone.

Validation that only fires after the submit button is clicked wastes the moment when a mistake is easiest to fix. A visitor who mistypes an email address wants to know immediately, while the cursor is still in that field. Not after filling in three more fields and clicking a button that bounces the whole form back with no memory of what was already typed.

The message matters as much as the timing. Invalid entry tells a visitor almost nothing. A note that the email address is missing the part after the at sign, or that a phone number needs an area code, tells a visitor exactly what to fix and where. Vague errors turn a short form into a guessing game. Guessing games lose visitors.

Where the error appears changes how fast it gets fixed. A single summary listed above the form, disconnected from the fields themselves, forces a visitor to scan back down and match each line to a box by process of elimination. That wastes time. Placing the message directly beside the field it belongs to removes that step entirely.

Marking required fields is worth a second look. Most fields on a short landing page form are required. Only one or two are optional. Marking every required field with a symbol clutters a short form for no reason. Marking the rare optional field instead is often the cleaner convention.

Field types should match the keyboard a phone shows for them. A phone number field that brings up the numeric keypad, an email field that surfaces the at sign, and a name field that does not fight autocorrect all remove small amounts of friction. Those amounts add up on a touchscreen, where most landing page traffic now arrives.

Autofill deserves to work rather than be fought. Standard field names and attributes let a browser fill in a name, address or card number the visitor already saved. That is faster than typing on a phone screen after arriving from an advert. Custom field markup that blocks autofill to achieve a particular visual layout trades a small design preference for a real increase in abandoned forms.

A failed submission is not always the fault of the visitor. The message should not imply otherwise. A network timeout or a server error calls for a plain explanation and a way to try again without losing what was already entered, rather than a generic error that reads the same whether the mistake was made by the visitor or by the system.

None of this shows up in a screenshot of the finished page. That is exactly why it gets skipped under deadline pressure. Testing the form by actually filling it in on a phone, making a few deliberate mistakes, and watching what happens catches problems a design review never will.
