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 Feel-good and Sustainable experience in the hero section, yet the sub-pages deliver content focused exclusively on high-volume, low-cost synthetic materials. There is a disconnect between the Sustainability sub-page’s vague environmental goals and the homepage’s focus on the rapid consumption of New Arrivals. Furthermore, the luxury positioning implied by terms like artisan craftsmanship is contradicted by the fast-fashion pricing structure found on the product listing pages. This cross-page drift suggests the brand identity shifts from conscious to commodity depending on the specific page depth.

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.
