Semantic Coherence: EHang – 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.

There is minimal semantic drift between the homepage and sub-pages. The homepage establishes a signal of being a ‘world-leading AAV technology platform’ and the sub-pages for the EH216-S and EH216-L deliver on this by detailing specific hardware configurations, such as the ‘coaxial dual-rotor power configuration’ and ‘carbon fiber composite materials.’ The messaging remains consistent from high-level mission statements to product-level specifications.

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.
