What a first time visitor meets between landing and first value.

Steps to first value

How far a new visitor travels before something useful happens.

80Strong

Signup form is 2 steps from the homepage. The form itself has 2 fields, both required: work email and password. A single sign on option via Google is offered. An evaluator reaches the form quickly.

1 observation recorded.

Required fields

How much you ask for before you give anything back.

93Strong

2 of 2 form fields are required: work email and password. 1 sign in provider is offered (Google). Both inputs carry validation rules. The form is minimal and does not ask for unnecessary information.

1 observation recorded.

Verification walls

How many gates stand between intent and access.

80Strong

No verification requirement appears on the signup page itself. Single sign on via Google avoids email verification entirely. The form does not block entry with a CAPTCHA or other check. Verification walls are absent or deferred.

1 observation recorded.

Error recovery

What happens when someone gets it wrong.

80Strong

2 of 2 inputs carry validation rules and descriptions. The form provides inline feedback. However, no inline error containers were detected, so recovery from a failed submission cannot be fully measured from the signup page alone.
