| Crawler visits Observed AI crawler visits in the study window. | 575,788 |
Population and method
Built from 575,788 AI crawler visits across 84 brands and 314,501 unique URLs observed between June 11, 2025 and February 1, 2026.
Where the evidence stops
This study measures observable crawler traffic rather than hidden fetches or internal cache reads.
One dominant e-commerce brand was excluded to keep the page-type patterns more generalizable.
Visit share and homepage preference vary sharply by bot family, so averages can hide crawler-specific behavior.
What to do with this
This sets the default operational baseline for AI crawl visibility work. Strategists must prioritize GPTBot compatibility to capture the majority of automated AI traffic.
