Useful takeaways from this story.

ChatGPT referral traffic grew 101% between January and August, with a 36% jump in August alone.

The useful part

A strong August ChatGPT's referral traffic rose 36% in August alone, its biggest monthly jump of the year. Gemini grew 1% over the same month, while Claude fell 15% and Perplexity 17%, according to BrightEdge. It is also sending substantially more users to the web than it was at the beginning of the year," said Jim Yu, BrightEdge's chief executive and co-founder.

How it works

  • Early this year, its data showed users switching quickly to whichever chatbot looked most advanced.
  • A lead on other measures too ChatGPT's lead shows up in BrightEdge's other data.
  • In June, the company found that OpenAI accounted for 96% of live AI agent activity on the web, meaning visits AI makes on a user's behalf.
  • OpenAI also made about half of the visits AI crawlers make to train models and build search indexes.
  • Similarweb found in July that AI search is fragmenting across more assistants.

What to take from it

BrightEdge linked the rebound to OpenAI's push to improve ChatGPT after Sam Altman declared a "code red" in December. Gemini reached a billion monthly users in August, and ChatGPT hit that mark in June. BrightEdge sells tools that help brands track how they appear in ChatGPT and other AI engines.

Details worth keeping

Gemini came second in August with 2.4%, BrightEdge said. ChatGPT sent about 22 times as much traffic as the three combined. AI tools still send far fewer visitors to websites than search engines do.
