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 | imrworldwide.com | zillow.com |
|---|---|---|
| robots.txt | Fetch failed: dns_error | Served and parsed |
| Google crawl posture | Blocked | Open |
| Unnamed crawler fallback | Unavailable | Partly Restricted they inherit the wildcard (*) group's rules |
| 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 | imrworldwide.com | zillow.com |

| Model training | Observation unavailable | Blocked |
| AI search | Observation unavailable | Blocked |
| Live assistant fetch | Observation unavailable | Blocked |
| Opt-out directives | Observation unavailable | Blocked |
| Ambiguous / undocumented | Observation unavailable | Not explicitly addressed |
Named agents
Measured differences appear first. “Not explicitly addressed” is not the same as allowed; the site's wildcard fallback governs that crawler.

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 →
