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 total collapse between the primary brand signal (a global cruise line) and the delivered substance (a server error). The homepage fails to provide any H1 or hero content that aligns with the industry’s expected value propositions like ‘unforgettable holidays’ or ‘curated itineraries’. This represents the maximum possible drift from user expectation to technical failure.

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.
