3m.com blocks AI crawlers
When we fetched 3m.com on 2026-07-12, its bot protection served a challenge instead of the page. Polite automated readers — including the crawlers behind AI assistants — get the same wall, so the site cannot be scored and is largely invisible to them. 161 of 970 sites (17%) are in the same position.
What the numbers mean
AI readiness is how cleanly an LLM fetcher or crawler can read the page: server-rendered main content, one clear H1, a meta description, structured data (JSON-LD), an explicit robots.txt policy for AI crawlers, llms.txt and agent signals. HTTP security covers the response headers browsers rely on: HSTS, Content-Security-Policy, X-Content-Type-Options, frame and referrer policies, secure cookies. Both are 0–100 with explainable, weighted checks; the composite weights them 55/45.
A high score doesn’t mean AI recommends the brand — it means AI can read it. Whether assistants actually name it when buyers ask is a different measurement: share of voice over time, which Crawlsonar tracks.
