Semantic Coherence — The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

A severe disconnect exists between the meta-signal and the delivered substance; the homepage promises an ‘intuitive, efficient, and useful’ experience, yet the signup and recovery sub-pages return 404 errors. This semantic drift is absolute, as the site promises a workflow that it fails to provide at the basic URL level. The primary signal of ’email that works’ is directly contradicted by the ‘Not Found’ errors on core user journey pages.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.
