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 disconnect between the primary signal in the meta title and the actual content delivered, as the sub-pages and homepage body are entirely empty. The homepage claims to offer a ‘Web应用防火墙’ (WAF), but provides no sub-pages to explain the implementation, pricing, or management of such a service. Without sub-page data to compare, the drift is measured by the 100% gap between the meta title’s promise and the blank technical reality of the site. This represents a total failure of the site to follow through on its core positioning as a security solution provider.

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.
