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.

The semantic drift is absolute; the H1 ‘Access Denied’ and hero-level text provide zero alignment with the expected Logistics signal of a national postal service. The heading hierarchy is incoherent for a business, consisting only of a technical error message that fails to inform the user of the brand’s purpose. There is no cross-page consistency as sub-pages are entirely missing or inaccessible, preventing any support for the homepage’s identity. The distance between the expected industry role and the delivered text is the maximum measurable drift.

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.
