Semantic Coherence: Mozilla – Signal Evidence & AI Readability

Mozilla

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 H1 ‘Internet for people, not profit’ is consistently supported by the About page’s manifesto and the Products page’s focus on privacy-first tools. Unlike typical SaaS sites that drift from ‘enterprise solutions’ to ‘cheap tools,’ Mozilla’s sub-pages reinforce the ‘independence’ and ‘control’ narrative across all products, including newer entries like Solo and 0DIN.

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.
