Semantic Coherence — 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.

The homepage Signal of being a brand within the Arts/Culture space has a maximum drift score of 8 due to the zero-content state of the sub-pages. There is no evidence that the Visit Us or What is On template sections—common to this industry—are populated with actual programming or event data. This represents a total failure of the sub-pages to deliver on the cultural mission implied by the industry classification. The cross-page consistency is fundamentally broken as there is no consistent messaging to evaluate against the brand promise.

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.
