ARCO
(https://arco.com) 📸 Data Snapshot: June 20, 2026Pull 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 minimal semantic drift between the homepage promises and the sub-page deliveries. The homepage hero section focuses on ARCO Rewards, which is directly supported by technical instructions and app download links on subsequent pages. The claim of renewable diesel on the homepage leads to a highly technical sub-page that explains the chemical process and environmental impact. However, the positioning of TOP TIER gas as high-quality is never actually quantified with specific lab results or comparative data across pages, leaving it as a floating signifier.
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.
