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.

There is a critical failure in signal-substance alignment as the slot designated for the HOMEPAGE returns a server error rather than corporate messaging. Because the sub-pages are effectively non-existent in the crawl, cross-page messaging consistency cannot be verified, which is scored as a total mismatch in the drift framework. The heading hierarchy is non-existent, providing no logical story about what the business does.

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.
