EFO (input form optimization)

EFO (input form optimization) is the process of making input forms on a website easier to use. For example, by reducing the number of required fields and displaying error messages in an easy-to-understand manner, we make it easier for users to complete the form to the end. By doing so, we aim to reduce the number of people who stop filling out the form midway, resulting in an increase in inquiries and purchases.
