When to use it
When form fields lack autocomplete attributes on a page with over 40% mobile share, where mobile submission rate trails desktop.
How to run it
Add correct autocomplete attributes to every field: name, email, tel, postal-code, cc-number. Use Google address autocomplete on the address block.
Why it works
Make the action easier to complete
Typing is the friction, and autofill removes it. Chrome's 2024 data showed the average site saw 75% lower form abandonment among autofill users, with ~35% faster completion.
