Semantic Coherence โ€” 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.

The homepage provides no H1 or hero text, creating a structural void where a value proposition should be. This absence of signal results in a partial alignment penalty, as there is no promise to compare against the sub-page delivery. Without content to analyze across the single provided page, the cross-page consistency remains untested, but the lack of a heading hierarchy is a total structural failure. The semantic drift is characterized here by the distance between a high-authority domain name and the absolute zero of the content provided.

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.
