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.

There is a notable drift between the ‘Specialist’ claim in the meta title and the lack of technical detail in the body content. The homepage H1 is missing, and the primary signal of being ‘networking specialists’ is supported only by the claim of having done it for ‘over 25 years’ without any technical evidence or service tier definitions. The sub-page navigation (Broadband, Networking, Internet) promises distinct services, but the text provided is mostly a repetition of generic SMB pain points.

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.
