Semantic Coherence: Vokera by Riello – 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.
18 Impact Weight: 20 / 100
90% Reputation

Alignment across the four pages is exceptionally high. The homepage signal regarding ‘Fixed Price Repair’ and ‘Maintenance Plans’ is directly supported by granular sub-pages for Combi and System boilers. There is no identity shift between the residential focus of the boiler pages and the clearly defined commercial catalogue found on the commercial sub-page.

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.

[H2] Controls

Central heating controls play an important part in a heating system.

[H3] Energy-related Products (ErP) and how it affects you.
Since September 2015 ErP legislation has been compulsory and requires all plumbing and heating appliances, including boilers, water heaters and renewable products, to have an energy label present.
Controls increase the energy efficiency of a heating system which is represented by an ‘uplift’ in the overall efficiency of the system. The uplift can range from 1% – 5% depending on how efficient the control is, with intelligent controls such as Vokèra’s outside weather compensation control and BeSMART, having a larger uplift than other non-intelligent controls.
When an appliance is fitted, the installer will be responsible for affixing the label and working out the system efficiency for you. However, the legislation allows you, the homeowner, to easily compare the energy efficiency of products in your home, allowing you to reduce energy consumption.
