What this checker looks for
The checker uses transparent heuristics rather than a black-box score. It flags empty fields, overly long blocks, and CTAs that do not contain clear action language. Treat the suggestions as editing prompts, not a ranking prediction.
A simple review order
Read the headline alone, then the headline with the supporting copy, then the CTA. If the reader still cannot tell what the product is or what to do next, shorten the message before adding more detail.
