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 detected across the crawled pages. The homepage establishes a clear promise of a long-acting, reversible, 99% effective implant, and the sub-pages provide granular evidence for each component of that claim. The transition from the homepage to the ‘How NEXPLANON Works’ and ‘Effectiveness’ pages maintains strict alignment in both technical mechanism descriptions and statistical efficacy 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.
