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.

The site exhibits high information density with a low ratio of fluff to substance. Headings often lead directly to specific product models such as the 1500D Combination Lock or the 410RED Lockout Padlock. The body text includes granular details, such as a customer testimonial citing a specific purchase date in September 1960 and an 8300-mile trip to Alaska, which serves as high-substance evidence rather than generic marketing claims.
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.

I purchased a combination Masterlock in September, 1960, for use in middle school gym. Since then, it served me through high school and college, was the lock on my bike chain, including a 3800 mile ride in 1976, for years, and secures my locker at our fitness center. Most recently, it protected a spare tire on our van (photo) during an 8300-mile trip to Alaska. After 64+ years of service with exposure to the elements it still works flawlessly. I wish all my purchases were of this quality. Parker - Ventura, CA More Testimonials or Share Your Story [H2] Uncover Insights Access relevant resources to help you live a safer and more secure life.

🧭 Industry Context — common generic-claim patterns in Security, Surveillance & Cybersecurity to weigh the text against
