How this site compares

Each row is one measured trait, not a composite score. Rank peers are Ranks 10,001–100,000; the second comparison is the full observed Tranco panel. Populations differ by metric and are printed with every rate.

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 10,001–100,000 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.

Put this site's measured policy beside another site. Botfy keeps missing evidence visible and does not assign a score or winner.

Live files on core77.com

The file as it exists on the host right now — may differ from what we measured. We link out rather than mirror (we store derived metrics, not raw bodies).

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.
