ChatGPT’s share of AI referral traffic in 2026
ChatGPT remains the biggest AI source of visits, but other assistants are catching up in some studies. The data is messy, and your own analytics are the only number that matters.
How much of AI referral traffic comes from ChatGPT? In 2026, the answer depends on the dataset.
What happened
- A B2B report from Goodie put ChatGPT at about 62.6% of AI referrals in March–April 2026, down from 89.1%, with Perplexity at 7.3%.
- A Statcounter-based roundup gave ChatGPT 78.16% of AI referrals in March 2026. Another source put it at 87.4%.
- A case study from Arc Intermedia claims AI chatbots send about 96% less referral traffic than Google Search.
The spread comes from different samples: B2B sites, ecommerce, publishers. Gemini and Copilot grow faster in some industries than others.
What it means for you
- Measure your own mix. Create an “AI assistants” channel in GA4 using referrer domains such as
chatgpt.com,perplexity.ai,gemini.google.comandcopilot.microsoft.com. - Small numbers, high intent. AI referral traffic is small, but visitors often arrive after a detailed answer and convert well.
- Analytics miss AI crawlers. Bots don’t run JavaScript, so tools like GA4 show visitors but never the crawlers that read your pages.
The BotReady AI tracker shows both: AI crawler visits from your server, and visitors from each AI assistant.
