Restricted by Design
◆65/100
This site restricts most AI crawlers by choice — 35 of 35 AI search and answer crawlers are blocked in robots.txt.
This site appears to intentionally restrict AI crawler access — a valid strategy many publishers and brands choose (for example, keeping content out of AI training). If that’s deliberate, the site is working as intended: the score below measures how open a site is to AI, so a low number here is the expected result of that choice — not a failure to fix.
