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.

The homepage promises a value proposition of helping developers sell units quickly with high quality/price ratios, yet the sub-pages fail to explain ‘how’. The /illustra/ page introduces an ‘Application TACTILE et INTÉRACTIVE’ as a major novelty, but this is not reflected in the primary service descriptions or the portfolio, creating a drift between the ‘innovation’ claim and the standard rendering ‘substance’ provided. The heading hierarchy is also incoherent, with the homepage missing an H1 entirely and the services page jumping directly to H6 markers.

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.
