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 is absolute because there is no homepage signal to compare against sub-pages. The H1 is missing, leaving the primary value proposition undefined. The disconnect between a URL and a functional business message is total, as the site provides no delivery on its presence.

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.
