Semantic Coherence: Sekonic – Signal Evidence & AI Readability

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 virtually zero semantic drift between the homepage signal and sub-page substance. The homepage meta data promises ‘precision exposure meters’ and ‘spectrometers,’ and the ‘Classroom’ sub-page delivers deep-dive tutorials on exactly how to use those meters in professional workflows. The messaging is consistent across pages, targeting a professional and educational audience without shifting into budget or generic consumer rhetoric.

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.
