Semantic Coherence: Mercury – Signal Evidence & AI Readability

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.

There is minimal semantic drift across the analyzed pages as the homepage ‘Our Services’ block aligns perfectly with the sub-page offerings. The homepage hero signals a multi-utility provider (Power, Gas, Internet), and the Electricity sub-page reinforces this by detailing bundles for broadband and mobile. There is no disconnect between high-level promises and the tactical reality of the packages offered. The heading hierarchy is consistent in its focus on customer acquisition through tangible ‘Join Offers’ rather than vague corporate positioning.

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.
