Review landing pages with AI and log the fixes

Give it a list of landing pages and a line on what they sell and who they are for, then run it whenever you want a review. Each page is fetched and read by the AI the way a conversion specialist would read it, looking for a buried or vague call to action, messaging that never says what the product is, layout that puts competing links in front of the offer, missing proof, and forms that ask for too much.

You end up with a tab named 'Landing page reviews' in your Google Sheet, with one row per finding: the date, the page, the area, what is wrong in the page's own words and the change to make. Rows are only ever added, so the tab becomes a record of what you were told and when. A page that will not load is reported and skipped rather than reviewed as if it were fine, and one failed page does not stop the rest.

You need a Google Sheet to write to; the tab and its headings are created on the first run.

What this page sells, who it is for, and what counts as a conversion: offerAndAudience Look for the things that actually lose conversions on this page: - Call to action: is the main action obvious, above the fold, and worded as a benefit rather than 'Submit' or 'Learn more'? - Messaging: within five seconds, does the page say what this is, who it is for, and why it beats the alternative? - Layout: what gets between a visitor and the action - competing links, walls of text, the offer buried below three scrolls? - Trust: is there proof a stranger would believe - named customers, numbers, guarantees, pricing that is actually shown? - Forms: how many fields, and is every one of them worth the drop-off? Reply with at most 8 findings, one per line, and nothing else. No numbering, no bullet characters, no introduction and no closing summary. Each line is exactly three parts separated by the pipe character: Area | What is wrong | What to change Area must be one of: Call to action, Messaging, Layout, Trust, Forms.
