AI Crawler robots.txt Study (Tranco top 10,000, October 2026)
Published by Desearch. Full write-up and method: https://www.desearch.ai/blog/ai-crawlers-robots-txt-study
What is in it
One row per domain for all 10,000 domains of the Tranco standard list (list ID 64VKX, downloaded 2026-10-13). robots.txt files were fetched on 13 October 2026 and parsed under RFC 9309.
| Column | Values |
|---|---|
| rank | Tranco rank |
| domain | domain |
| band | rank band: 1-100, 101-1000 or 1001-10000 |
| training | blocked (at least one AI training crawler user-agent blocked site-wide) or not_blocked |
| search | blocked (at least one AI search crawler user-agent blocked site-wide) or not_blocked |
| user_triggered | named (at least one user-triggered AI fetcher named in the file) or not_named |
Sites that served no valid robots.txt are marked no_valid_robots_txt. There are no per-crawler columns.
Headline results (6,480 valid robots.txt files)
- 18.6% block at least one AI training crawler site-wide (1,203 of 6,480).
- 11.0% block at least one AI search crawler site-wide (716 of 6,480).
- 2.4% block the main search engine crawler site-wide (157 of 6,480), the control.
- 13.2% name at least one user-triggered AI fetcher (856 of 6,480).
- 64.8% of the 10,000 domains served a valid robots.txt (6,480 of 10,000).
Limits
- robots.txt is a request, not enforcement. This study measures stated policy, not crawler behaviour or firewall blocking.
- Tranco ranks popular domains; results describe popular sites, not the whole web.
- Single snapshot.
