The evidence.

| One-visit sessions Most AI crawler visits are one-and-done sessions. | 88.5% |
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
Strategists must optimize high priority pages for immediate data extraction. Since crawlers rarely navigate multiple pages within a single session, critical information and context must be fully accessible on the entry page to ensure accurate ingestion by large language models.
