Top-level domain segment

AI crawler access on .cz domains

18 of the 132 domains measured in this segment refuse a request from an identified AI user agent at the edge, 14% of the segment, against 7% whose robots.txt disallows an answer engine at the site root. The block that costs these sites citations is not the one written in the file. That answer-engine rate is level with the corpus rate of 7%, which is itself measured across 30,223 domains.

Mean AI access score across those 132 domains is 73.8 of 100, 12 of them publish an llms.txt (9%), and 51 publish structured data an answer engine can parse (39%).

Block rate is the share of this segment's domains holding a policy record for that agent whose robots.txt disallows it at the site root, shown with its numerator and denominator. Denominators differ between agents because a record only exists once a domain has been measured for it. A domain serving no robots.txt counts as allowing everything, which is what the standard specifies.

What this segment does not tell you read this before citing it

A top-level domain is a weak proxy for jurisdiction. Most of them are open to any registrant anywhere, so a domain under a country-code registry may be operated from outside that country by a company no local law reaches. Read these rows as differences between registration communities and the publishing cultures inside them, not as differences between legal regimes.
