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 slight disconnect between the homepage’s high-level brand positioning for Pentosin and the heavy integration of Rein products and CRP Automotive corporate links in the What’s Hot section. The homepage H1 promises technical fluids from first fill to last, but the current crawl shows that sub-pages for Antifreeze, Brake Fluid, and Hydraulic Fluid are effectively empty (0 character count). This creates a structural drift where the navigation promises depth that the current page architecture fails to deliver in a single crawl session.

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.
