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 severe disconnect between the primary navigation signals and the content delivered. The homepage promises high-value substance via links for what-is-kybella and kybella-before-and-after, but both sub-pages return a 403 Forbidden error. This creates maximum semantic drift where the brand claims to provide patient resources but fails to deliver accessible data. Furthermore, the H1 is missing on the homepage, while the meta title claims to be the First and Only treatment, a bold assertion that is never substantiated in the accessible page body.

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.
