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.
| Evidence | iop.org | microsoftazuread-sso.com |
|---|---|---|
| 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.
| Declared purpose | iop.org | microsoftazuread-sso.com |
|---|---|---|
| Model training | Blocked | Observation unavailable |
| AI search | Not explicitly addressed | Observation unavailable |
| Live assistant fetch | Blocked | Observation unavailable |
| Opt-out directives | Blocked | Observation unavailable |
| Ambiguous / undocumented | Not explicitly addressed | 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 →
