National Gallery of Australia
(https://nga.gov.au) 📸 Data Snapshot: May 28, 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.
Semantic drift cannot be measured through cross-page contradiction because both the homepage and sub-pages returned empty strings in the crawl. However, the Heading Hierarchy Coherence receives a maximum penalty (5/5) because a visitor cannot determine the gallery’s purpose from the non-existent structure. The homepage promise is invisible, and the sub-page delivery is non-existent, indicating a total breakdown in signal-substance alignment.
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.
