Semantic Coherence โ€” 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.

Semantic drift cannot be accurately measured because there is no hero section or H1 to establish an initial brand promise. The homepage consists entirely of a WAF challenge, which creates a total disconnect with any potential sub-page content. However, the heading hierarchy is flagged as incoherent because the only available headings (H3 tags) relate to JavaScript errors rather than business operations. This total lack of structural relationship means the headings fail to tell any logical story about the brand or its services.

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.
