A/B Testing Idea #304 - With forms, offer fields which match the required information

Tactic_With forms, offer fields which match the required information


Matching your field layout to whichever input format is required will improve user experience by giving assistance and avoiding errors or frustration. For example, when asking for a phone number you should use 3 spaces, rather than one large one, with only enough character capability to input the required number of digits. This makes the form easier to fill in and will avoid any errors as the user won't be able to forget a digit or add an additional one accidentally.

Aesthetic-Usability Effect

Aesthetic designs are perceived as easier to use than less-aesthetic designs, and are more likely to be purchased regardless of functionality.

Processing Efficacy

We tend to prefer things that are simple for us to understand or use.
