Semantic Coherence: Castrol – Signal Evidence & AI Readability

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 visible drift between the homepage’s ‘Pathway of Change’ signal and the sub-page content which remains focused on high-performance internal combustion engine motorsport. While the hero section promises a journey toward ‘tranquillity’ and EV technology, the Global Sponsorships page is dominated by traditional rally raids, Dakar 2026, and MotoGP partnerships. The ‘Sustainability’ H3 on the homepage leads to a ‘holistic programme’ (PATH360), yet the tactical pages emphasize ‘fighting friction’ and ‘extending engine life’ for fossil-fuel-dependent vehicles.

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.
