Study: 20% of ChatGPT Users Click to Google
▼ Summary
– Over 30% of ChatGPT’s outbound referral traffic goes to just ten domains, with Google alone receiving 21.6%.
– ChatGPT triggers a web search for only 34.5% of queries, a decline from 46% in late 2024.
– The number of domains receiving referrals from ChatGPT expanded, peaking at around 260,000 in 2025 before decreasing to near 170,000.
– Most user prompts (65-85%) are complex and conversational, not resembling traditional keyword-based search queries.
– User engagement is deepening, with queries per session increasing by 50% in late 2025.
A new analysis of user behavior reveals that ChatGPT referral traffic is heavily concentrated, with a significant portion flowing directly to Google. According to a recent Semrush study, over 30% of all outbound clicks from the AI platform are directed to just ten domains. Google alone captures 21.6% of this traffic, highlighting a key pathway for users seeking further information. This concentration occurs even as the total number of websites receiving any referral traffic from ChatGPT has expanded significantly.
The research indicates a notable shift in how the tool interacts with the web. ChatGPT now initiates a live web search for only 34.5% of user queries, a substantial decrease from 46% in late 2024. This suggests the model is relying more on its internal knowledge base. It primarily activates search under specific conditions: when a user explicitly asks for sources, when questions concern very recent events, or when the AI lacks confidence in its pre-trained information.
For marketers and publishers, these trends carry important implications. While overall referral traffic from ChatGPT surged by 206% from January 2025 to January 2026, this growth is not distributed evenly. Gaining visibility within a ChatGPT response does not guarantee meaningful website traffic, as most sites receive only a minimal trickle from a long tail of referrals. The decline in search-triggered queries further limits opportunities for earning direct citations and click-throughs.
User engagement with ChatGPT is also evolving. The data shows that between 65% and 85% of user prompts do not resemble traditional keyword-based searches, instead favoring more complex, conversational requests. This reflects a fundamental behavior shift away from standard search engine patterns. Concurrently, user engagement is intensifying, with the average number of queries per session increasing by 50% in late 2025.
The study, which examined over 1 billion lines of U. S. clickstream data from October 2024 to February 2026, paints a picture of a platform whose influence on web navigation is still crystallizing. The number of domains receiving referrals peaked at approximately 260,000 in 2025 before stabilizing near 170,000. This plateau, alongside the concentrated traffic flow, underscores that ChatGPT’s role as a traffic driver remains selective and unpredictable for most online destinations.
