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 massive disconnect between the ‘Signal’ in the meta-description and the ‘Substance’ on the page. The metadata promises a comprehensive radio player with ‘rock, pop, jazz, classical, and electronic’ music, but the homepage content fails to deliver even a single link or button to these genres. This is a primary example of semantic drift where the marketing promise describes a robust platform that does not exist in the crawled text. No sub-pages are available to bridge the gap between the ‘free online radio’ claim and the nearly empty interface.

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.
