Information Density: Substack – Signal Evidence & AI Readability

Substack

(https://substack.com) 📸 Data Snapshot: May 22, 2026
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 Information Density score is exceptionally high due to a total lack of specific data points across the 324 total characters crawled. Headings such as ‘Make money doing the work you believe in’ and ‘A new economic engine for culture’ contain zero numbers, percentages, or named entities. The body substance ratio is virtually zero, as the text consists almost entirely of calls to action like ‘Start your Substack’ and ‘Join the most interesting and insightful discussions’ without explaining the mechanics of the platform.

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.
