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 virtually no semantic drift between the homepage signal and its sub-sections. The primary H1 promise regarding energy prices is immediately supported by the Fix and Fall tariff description. The secondary focus on home services (HomeCare, boilers) and green tech (heat pumps, solar) is logically tiered and remains consistent throughout the page hierarchy. The target audience remains consistently residential and landlord-focused.

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.

Price review based on the Ofgem price cap after 12 months. See britishgas.co.uk/verify for more info.

Save 25% on the electricity used to charge your Hive-connected EV charger, applied as a credit to your electricity account. Power+ is only available to customers with a compatible EV charger, a British Gas electricity tariff, and a smart meter in credit mode; savings are based on the British Gas EV Power May27 tariff (correct as of 01/04/2026), assume 3.3 miles/kWh efficiency, and require all charging to occur in Power+ mode during off-peak hours managed by Hive.
