Editorial interest 82/100 Selection signal · not a rating of the site

Crawlglass fetches a web page without a browser or JavaScript and reports what AI assistants can actually read, miss, and potentially misunderstand.

Landing page captured for the 2026-09-12 issue.

Field notes

Crawlglass tests a page under crawler-like conditions, specifically without a browser or JavaScript, and exposes the text returned to that fetch. Its sample report includes a 77/C result, 573 words present in the HTML, missing image alt text, and absent JSON-LD. The site also publishes a 20-site comparison: three pages reportedly returned a bot wall or robots.txt refusal, while four of the 17 accessible pages had no structured data.
