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 zero semantic drift observed across the analyzed pages. The homepage H1 Nizoral Anti-Dandruff Shampoo sets a clear medicinal tone that is consistently supported by the sub-pages on hair loss and dandruff education. The value proposition remains focused on the root cause (fungus) without drifting into generic luxury or lifestyle beauty claims.

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.
