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
- Optimize entry pages and internal links for the specific crawlers appearing in server logs.
- Treat crawler families differently to account for varying site architecture traversal.
- Use low-depth answer pages to improve the odds that a one-visit crawler finds citeable content.
Operators must segment crawler logs by bot family to accurately measure site coverage and allocate technical SEO resources, rather than applying a uniform strategy to all AI agents.
