Measured takeaway
miguelgrinberg.com blocks model-training crawlers; warenvergleich.de has mixed rules for model-training crawlers.
miguelgrinberg.com blocks GPTBot; warenvergleich.de partly blocks GPTBot.
Measured in Botfy's 2026-09-07 publication.At a glance
A difference appears only when both sites have comparable evidence. Unavailable or unresolved observations remain incomplete.
| Evidence | miguelgrinberg.com | warenvergleich.de |
|---|---|---|
| robots.txt | Served and parsed | Served and parsed |
| Google crawl posture | Open | Open |
| Unnamed crawler fallback | Unrestricted no wildcard (*) group exists, so no rule applies to them at all | Unrestricted no wildcard (*) group exists, so no rule applies to them at all |
| Base /llms.txt | Not probed | Not probed |
Treatment by purpose
Only resolved blocked, allowed, or mixed states count as a policy agreement or difference. Unnamed agents still inherit each site's wildcard rules.

Named agents
Measured differences appear first. “Not explicitly addressed” is not the same as allowed; the site's wildcard fallback governs that crawler.

How each site compares with its own rank peers
The sites may belong to different rank bands. Each percentage keeps its own population and denominator; Botfy does not subtract rates from unlike cohorts.

How this comparison is measured
Both sites use Botfy's latest published observations. A missing fetch, unresolved agent verdict, and measured absence are different states. Peer percentages use each site's exclusive Tranco rank band and print their own denominator. Populations, sources, and limits →
