This site serves a robots.txt and names 14 AI crawlers, blocking none.
How this site compares
Each row is one measured trait, not a composite score. Rank peers are Ranks 1–1,000; the second comparison is the full observed Tranco panel. Populations differ by metric and are printed with every rate.
| Trait | This site | Ranks 1–1,000 | Observed Tranco panel |
|---|---|---|---|
| robots.txt served | Yes | 53.3% of 1,000 | 61.7% of 1,212,578 |
| robots.txt returned 404 | No | 4.6% of 1,000 | 8.4% of 1,212,578 |
| Blanket disallow | No | 8.9% of 529 | 10.3% of 740,113 |
| Effectively open file | No | 11.3% of 529 | 25.7% of 740,113 |
| Wildcard group | Yes | 95.1% of 529 | 89.8% of 740,113 |
| Sitemap declared | Yes | 66.0% of 529 | 60.7% of 740,113 |
| Over the RFC parse limit | No | 0.8% of 529 | 0.3% of 740,113 |
How these comparisons are measured
Status rates use canonical robots.txt observations. File traits use only parsed canonical files. A missing metric stays unavailable rather than becoming 0%. Rank bands are exclusive, so Ranks 1–1,000 does not include more popular bands.
Treatment by purpose
Declared purpose comes from the versioned agent registry. These are separate policy dimensions, not inputs to a score. An unnamed purpose is not automatically allowed; it inherits the wildcard rule described below.
Named agents
Every tracked agent this robots.txt names, grouped by operator, with the rule that applies under RFC 9309 group matching. A peer targeting rate means sites that name the token; it is not a block rate.

Raw observations
2 crawls, every source
A domain usually has more than one observation per crawl because we see it in the Common Crawl shard stream and fetch it ourselves. These are not duplicates — they are independent observations of the same file, and one is marked canonical. The rest of this page reads the canonical row.
