Information Density: McMaster-Carr – Signal Evidence & AI Readability

McMaster-Carr

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 maximum information density with zero fluff headings. All H2 headings like Fasteners, Rotary Motion, and Hydraulics are specific nouns describing the product range. The body text is composed of hundreds of technical product categories (Screws, Bolts, Eyebolts, U-Joints) with a total absence of power words or marketing filler. The meta description provides hard numbers, including a 595,000+ product count and a 98% shipment rate.

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.
