Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

The site exhibits high information density with a low fluff-to-substance ratio. While headings like ‘London’s most central venue’ are slightly aspirational, the body text provides concrete specifications such as capacity ranges (e.g., ‘120-280′ for the Burdett Suite) and technical details like ’85-inch presentation screen’ and ‘hybrid-capable technology’. Unlike many venue sites, H2 and H3 tags are primarily used for named entities (The Green House, Maynard Theatre) rather than power-word slogans.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.
