ENHERTU (Daiichi Sankyo, Inc.)
(https://enhertu.com) 📸 Data Snapshot: June 20, 2026Pull 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 zero semantic drift observed between the homepage and sub-pages. The homepage H1 establishes the drug as an ‘FDA-approved treatment for several types of cancer,’ and the sub-pages for breast and lung cancer provide granular, consistent details about those exact indications. The transition from general availability on the homepage to specific eligibility criteria on the sub-pages is logically sound and medically precise.
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.
