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 measured because no sub-pages were accessible for comparison. The homepage H1 provides a system error rather than a value proposition, making alignment evaluation impossible. Without secondary pages, there is no cross-page messaging to check for contradictions. The heading hierarchy is technically coherent for an error page but provides zero business logic.

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.
