certinia.com and enchantedlearning.com

certinia.com #36,069 enchantedlearning.com #36,070

Measured takeaway

certinia.com allows AI-search crawlers; enchantedlearning.com has mixed rules for AI-search crawlers.

certinia.com allows GPTBot; enchantedlearning.com partly 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.

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.

Ambiguous / undocumented Blocked Mixed

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 →
