Alcatraz Island Guide
(https://alcatrazislandguide.com) 📸 Data Snapshot: June 21, 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.
A massive disconnect exists between the Signal (meta_title promising ‘Book Ferry & Audio Guided Tours’) and the Substance (zero characters of text). The homepage promises ‘behind the scenes experiences’ in the meta description, but the sub-pages provide no content to deliver on this promise. This represents the maximum possible semantic drift: promising a complex service while delivering a literal vacuum.
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.
