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 virtually zero semantic drift between the homepage signal and sub-page substance. The homepage H1 ‘Effective diaper rash relief that goes on smoothly’ is directly supported by the product pages which detail the ‘rich, creamy ointment’ texture and therapeutic actions. The messaging is consistent across the site, maintaining a focus on two specific formulas (Original and Extra-Strength) without expanding into unrelated or unsupported health 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.

[H3] What is diaper rash?
Diaper rash is the result of your baby’s skin getting irritated from a soiled or wet diaper. A child with very sensitive skin may be more prone to get diaper rash or a rash can happen when feces or urine in the diaper are in contact with the skin for too long, making the skin sore and red.
