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.

Semantic Coherence Homepage promise vs. Sub-page reality.

100% Reputation

There is zero semantic drift detected between the homepage and sub-pages. The homepage promises a ‘Business’, ‘Personal’, and ‘Trainer’ lineup, which is precisely mirrored in the navigation and the granular model pages for the M500 and M350. The technical specifications promised in the ‘Specifications’ H3 on model pages are delivered with high-fidelity performance metrics.

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.
