llms.txt GeneratorWhich AI crawler shows up most often?
Mostly, GPTBot shows up most often. It accounts for 57.2% of observed crawler visits in the study, far ahead of OAI-SearchBot at 15.1%.
The key numbers.
- GPTBot share
- GPTBot is the dominant crawler by observed visits.
- 57.2%
- OAI-SearchBot share
- SearchBot is the second-largest crawler in the study.
- 15.1%
- Crawler visits
- Observed AI crawler visits in the study window.
- 575,788
If a site is being read by AI systems at all, GPTBot is the first crawler family most teams will encounter, meaning optimization efforts should prioritize OpenAI bot behaviors.
The evidence.
| Measure | Result |
|---|---|
| GPTBot share GPTBot is the dominant crawler by observed visits. | 57.2% |
| OAI-SearchBot share SearchBot is the second-largest crawler in the study. | 15.1% |
| 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
- Optimize entry pages and internal links for the crawlers that actually show up in your logs.
- Treat crawler families differently because they do not read the same site architecture the same way.
- Use low-depth answer pages to improve the odds that a one-visit crawler still finds something citeable.
Operators must allocate technical SEO resources toward the bots actually consuming their bandwidth. Knowing GPTBot dominates allows teams to prioritize log analysis and server capacity for OpenAI user agents.
