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.

Significant semantic drift occurs between the functional minimalism of the homepage and the conceptual high-tech narrative of the About page. The homepage (URL 0) presents a simplified tool-based interface (Gmail, Search), while the About page (URL 5) attempts to position the company as a leader in Quantum Computing and AI, creating a disconnect in user intent. This drift is exacerbated by the technical failure of core utility pages like /advanced_search/ and /imghp/, which promise advanced functionality but deliver 404 errors. The messaging consistency is poor as the site oscillates between a ‘helpful tool’ and a ‘cutting-edge research entity’ without a clear structural bridge.

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.
