Top fix
Add one supplied, verifiable proof point next to the primary CTA.Illustrative synthetic excerpt only. It demonstrates grounded placeholders rather than a claimed live conversion result.
The screenshot or copy is sent to ChatGPT. Remove unpublished customer names, private pricing, traffic or conversion data, credentials, and confidential claims that are not required for the review.
Yes. A screenshot lets the GPT review both visible copy and layout evidence. A cropped screenshot should be assessed only within the visible area.
Yes. Copy-only input is supported, but Visual hierarchy should be scored 0/5 as unobservable rather than inferred.
It should not. Missing audience, proof, analytics, sample, or test parameters stay as explicit square-bracket placeholders.
Yes. In the same conversation it should reuse the eight-row scorecard, mark every dimension improved, regressed, or unchanged, and explain every score change.
Choose another input and output contract from the same verified page set.
