Landing page message match checker

Paste an ad or email promise next to landing page HTML and get element by element mismatches with scores and concrete rewrite targets.

Paste the promise and the page to see each mismatch with a rewrite.

Every check here is literal and explainable: the keyword and the ad's key words must reappear in the headline or title, the ad's numbers are compared per kind (percent, price, duration) so 20 percent in the ad against 15 percent on the page fails loudly, the ad's action verb must show up in a link or button, and proof sentences must repeat somewhere on the page. The score only ranks fixes; it is not Google's Quality Score and predicts no auction outcome. Pages pasted as plain text cannot yield buttons or subheads, so those checks are marked not checked. Scripts and styles are stripped before reading, and markup that only exists after JavaScript runs will not appear unless you paste the rendered HTML.
