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.

Information density is maximum. The headings H2 and H3 contain zero power words or marketing fluff, focusing entirely on the factual notification of service unavailability. Body text is highly specific, citing exact dates such as April 6, 2022, and specific service names including Yahoo! Mail and PayPay Card, resulting in a 0% fluff-to-noun ratio.

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.
