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.

Maximum semantic drift is inferred as the primary signal fails to provide even a baseline H1 or hero message. Without sub-page data to compare, the site exists as a digital void where the promised signal (homepage) contains no substance. This results in a complete disconnect between the website’s existence and its communication of value.

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.
