heinz.com and hostingdunyam.net

heinz.com #55,728 hostingdunyam.net #55,730

Measured takeaway

heinz.com publishes a genuine /llms.txt; hostingdunyam.net was probed and did not have a genuine base file.

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.

Google crawl posture Open Open
Unnamed crawler fallback Allowed the wildcard (*) group is effectively open Unavailable
Base /llms.txt Published Not found when 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 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 →
