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.
A profound disconnect exists between the meta_title ‘Facebook’ and the provided content, which contains zero functional information or value propositions. There is no H1 or hero text to align with the homepage’s primary signal, and the lack of sub-pages in the dataset prevents any cross-page verification. This represents maximum signal-to-substance drift, as the brand’s implied promise of a global social network is entirely unsupported by the evidence provided. The heading hierarchy is non-existent, meaning there is no logical story or structural relationship between the site’s identity and its delivered content.
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.
