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 severe semantic disconnect between the primary signal (the URL rubiconproject.com) and the substance provided (‘Just a moment…’). The homepage H1 is missing, and because no sub-pages were crawled due to the bot-protection intercept, there is no cross-page consistency to evaluate. The lack of a heading hierarchy results in a score of 5, as a reader cannot understand the business purpose from the structural markers alone.

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.
