Semantic Coherence: Whirlwind – 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 between the promise and delivery. The homepage promises ‘audio interface, fiber optic, and AC power solutions,’ and the /catalog/ and /new-products/ pages deliver exactly those technical specifications. The only drift is technical: the homepage repeats the H1 ‘Welcome to Whirlwind’ and H4 headers four times, suggesting a template error rather than a messaging pivot.

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.
