Measured takeaway

Botfy does not have comparable evidence for a strong policy takeaway; the available states are shown below.

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.

Evidencediy-shop.jp sysupgrade.org
robots.txt Served and parsed Fetch failed: dns_error
Google crawl posture Open Blocked
Unnamed crawler fallback Partly Restricted they inherit the wildcard (*) group's rules Unavailable
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.

AI search Allowed Observation unavailable
Live assistant fetch Blocked Observation unavailable
Opt-out directives Blocked Observation unavailable
Ambiguous / undocumented Blocked Observation unavailable

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 →
