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.

A severe signal-substance disconnect is observed where the ‘HOMEPAGE’ signal and URL ‘merck-animal-health.com’ suggest a global authority in veterinary care, yet the actual content delivers only a technical rejection. The drift is measured as maximum (8 points) because the hero-level promise of a brand entity is immediately invalidated by the H1 message. There is no heading hierarchy to analyze, as the only present heading is a system-level error message that fails to support any business identity.

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.
