A referral is a visit to a website that came from a click inside a chatbot. StatCounter only sees websites that run its tracking code, across more than 1 million sites. This is not a count of users or prompts. A chatbot that shows more links in its answers can send more visits per user. So read these numbers as each chatbot's share of the traffic AI assistants send to websites. StatCounter publishes this data under a CC BY-SA 3.0 licence. Our calculations from it, and the downloads on this page, use the same licence. ## Frequently asked questions ### What is ChatGPT's market share?
