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 complete semantic mismatch exists between the industry classification and the actual content. The meta title ‘Just a moment…’ represents an 8-point signal-substance alignment failure, providing zero delivery on the expected Software/SaaS value proposition. The heading hierarchy is entirely absent, resulting in a 5-point penalty for incoherence as no story or structure is presented.

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.
