Test Design Diagnostic Prompt

Runs your test plan through a pre-flight check before you launch it, catching the structural mistakes that produce an unreadable result days or weeks later — too many variables changed at once, not enough traffic to detect the effect, no pre-committed decision rule.

For anyone about to run a test on a landing page, ad, email, or pricing page. You walk away with a pass/fail on the test as designed and the specific fix needed before you hit launch.
