Following increased awareness, the share of GPTBot-blocked enterprise domains dropped from 38% to 23%.
The share of Fortune 500 domains blocking GPTBot in robots.txt fell from 38% to 23% over the first quarter of 2026, driven by growing awareness of the citation visibility impact. The shift is concentrated in technology, media, and retail — legal, finance, and healthcare remain the most restrictive sectors.
The pattern suggests that enterprise legal teams are beginning to differentiate between allowing crawl access for citation purposes and allowing training data inclusion — two distinct concerns that robots.txt cannot fully separate. Several brands have moved to selective access rules (allow key product pages, block internal/auth paths) rather than blanket block or allow.
The remaining 23% of blocked domains are increasingly concentrated in regulated industries where legal risk aversion outweighs citation benefits. For these brands, partial access strategies — allowing GPTBot on marketing and public content while blocking authenticated paths — represent a middle ground.
*What this means:* If your domain still has a blanket GPTBot Disallow, you are in an increasingly small and visible minority. The cost in citation share is measurable and growing. See the robots.txt and LLM crawler access playbook for the correct access pattern, or scan your domain to check your current bot access status.
