Systane (Alcon)
(https://systane.com) 📸 Data Snapshot: June 19, 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.
The site exhibits maximum semantic drift because the homepage promises product discovery and planning, yet the primary sub-pages (Where to Buy, Products, Plan Real Relief) all return ‘Web Site Not Found’ errors. There is a total disconnect between the H2 ‘BROWSE PRODUCTS’ signal on the homepage and the actual delivery, as the link leads to an Acquia Cloud error page. This represents a complete failure of the site to deliver the substance promised in its navigational hierarchy.
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.
