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.

Semantic drift is significant because the sub-pages for Collision and Trade Professionals contain identical text and heading structures to the homepage in the provided data. The promise of the URL acdelco.com/collision is a focused deep-dive into collision repair parts, yet the content delivered is the general brand message for the whole catalog. This represents a failure of the site to deliver specific content for specialized navigational paths. The heading hierarchy is logically consistent as a catalog, but it fails to adapt to the specific intent of the strategically selected sub-pages.
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.
🏗️ Semantic Structure — heading hierarchy & page identity (the promise the page makes)
