Cloudflare Radar
Monthly shares of web traffic from Cloudflare Radar since May 2022: AI crawlers such as GPTBot and ClaudeBot as a share of all requests, the largest crawlers individually, bot against human traffic, how much of Cloudflare's verified bot traffic comes from AI crawlers rather than search engines, and the share of sampled sites whose robots.txt blocks or allows each crawler. Every value is a percentage, not a count.
Cloudflare decides which visitors count as AI crawlers. The list also holds normal search crawlers — Googlebot is the largest one in it. Radar publishes shares, not request counts.
All AI crawlers
Crawler traffic mix
These three lines do not add up to 100%. Cloudflare puts the rest in a mixed class it counts as both human and bot.
Human
Non-AI bots
Top AI crawlers
Each line is a share of the requests from AI crawlers, not of all web traffic. Together the lines add up to about 100%.
GPTBot (OpenAI)
ClaudeBot (Anthropic)
Bytespider (ByteDance)
Amazonbot
Meta
Googlebot (Google)
Bingbot (Microsoft)
Applebot (Apple)
Claude-SearchBot (Anthropic)
Bot vs human traffic
⚠ Cloudflare counts these two lines with an older method than the crawler lines. It gives a share about 23 points lower, so compare the trends, not the numbers.

Sites blocking AI crawlers
Cloudflare reads about 4,000 robots.txt files each week. Each line shows the share of those files that block the whole site to one crawler. ⚠ Since July 2025 Cloudflare adds this block to new sites itself, so a block is not always the site owner's choice.

Sites explicitly allowing AI crawlers
Each line shows the share of the same files that give one crawler full access. ⚠ A site can block one part and allow another, so it can appear in both groups.

Bot traffic composition
Cloudflare verifies each crawler before it counts it, and it adds new ones over time. We use only the crawlers that were on its list in every month, so a new arrival cannot change these charts.
