cipd.co.uk #44,882 reference-global.com #44,880

Measured takeaway

cipd.co.uk allows model-training crawlers; reference-global.com blocks model-training crawlers.

cipd.co.uk allows GPTBot; reference-global.com 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.

Evidencecipd.co.uk reference-global.com
robots.txt Served and parsed Served and parsed
Google crawl posture Open Open
Unnamed crawler fallback Allowed the wildcard (*) group is effectively open Partly Restricted they inherit the wildcard (*) group's rules
Base /llms.txt Not found when probed 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 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 →

Keep comparing

Each suggestion replaces one side using an editorial collection or current rank proximity. Neither means the sites have similar policies.
