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.

There is virtually zero semantic drift between the homepage signal and sub-page substance. The homepage meta description promises flight tracking, terminal services, and parking info, which are directly fulfilled by the ‘Services’ and ‘Ground Transportation’ sub-pages. Specifically, the ‘Ground Transportation’ page provides granular details on BART, Waymo, and pickup locations that align exactly with the hero-level convenience promises.

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.
