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.

Semantic Coherence Homepage promise vs. Sub-page reality.

There is a catastrophic disconnect between the homepage signals and sub-page substance. The homepage hero section and H2s promise a Product Museum, Our Technologies, and a deep dive into Truth in Sound, yet every strategically selected sub-page returns a 404 Page Not Found error. This is maximum semantic drift: the site’s navigation structure promises authority and history (Museum) that the actual technical implementation fails to deliver. The meta-titles for these pages even explicitly state 404, contradicting the premium HiFi positioning of the homepage.

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.
