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 classified as absolute because the primary signal from the homepage is non-existent. There is no H1 or hero section text to set an expectation, meaning the sub-pages have no core promise to align with or contradict. This total failure in cross-page messaging consistency suggests a broken or placeholder digital presence. The heading hierarchy is also entirely absent, providing no logical story or structural relationship for a user to follow.

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.
