Semantic Coherence: Autotrader โ€“ Signal Evidence & AI Readability

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.

No semantic drift can be measured across pages as only one page was successfully crawled. The homepage H1 signals a technical failure, and there are no sub-pages to provide a hero promise or conflicting service descriptions. The lack of heading hierarchy beyond a single H1 indicates a total failure of the site to deliver a logical story or consistent business positioning. The disconnect is not between claims, but between the meta_title Autotrader and the reality of the unavailable service.

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.
