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 severe signal-substance disconnect between the target URL (nest.com) and the primary content delivered (Google privacy notice). The homepage H1 provides no alignment with a SaaS value proposition, and because there are no sub-pages provided to support the brand identity, the site exists in a state of total semantic drift. The heading hierarchy is non-existent beyond a single H1, offering no logical narrative for a business entity.

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.
