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.
Semantic Coherence
Homepage promise vs. Sub-page reality.

There is virtually no semantic drift between the homepage signal and sub-page substance. The homepage H1/Hero area promises ‘Engine Protection Guaranteed’ and ‘Total Protection,’ which is meticulously categorized on the products page into vehicle-specific fluids (European Violet, Asian Red, etc.). The messaging is consistent across the ‘How To’ section, which reinforces the technical claims made in the marketing hero sections.
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.
