Similarweb’s AI traffic share chart is clean and directionally useful, but without a clear methodology it’s hard to fully trust the numbers. Cloudflare’s 2025 Internet Year in Review, based on real traffic across its global network, confirms the bigger picture: AI platforms and bots are now a dominant force on the Internet, with heavy crawling and very little traffic sent back.

I recently saw this Similarweb Global AI traffic share chart: [link](https://x.com/Similarweb/status/2008805674893939041).

It’s clean, shareable, and feels directionally right but it’s hard to fully trust the numbers since Similarweb doesn’t clearly publish their methodology (at least I couldn’t find it).

So while Similarweb gives us a compelling visual, Cloudflare released their 2025 Internet Year in Review, which is based on actual traffic Cloudflare sees across its global network.

A few AEO takeaways worth digging into:

• AI platforms now dominate Internet services
Based on Cloudflare’s data, the top AI services in 2025 were led by ChatGPT, Claude, Perplexity, and Gemini. See the full list here: [link](https://radar.cloudflare.com/year-in-review/2025#internet-services)

• GoogleBot is still the largest crawler but AI bots are now right behind it. GPTBot, BingBot, Meta, and Amazon bots are among the highest-volume verified bots on the Internet. [link](https://radar.cloudflare.com/year-in-review/2025#per-bot-traffic)

• AI bots generated ~4.2% of all HTML requests. [link](https://radar.cloudflare.com/year-in-review/2025#workers-ai-model-and-task-popularity)

• AI is not very generous.
Cloudflare’s crawl-to-refer ratios show heavy crawling with minimal traffic sent back. [link](https://radar.cloudflare.com/year-in-review/2025#crawl-refer-ratio)
