ChatGPT Lost 60 Million Users. Referral Traffic Went Up.
ChatGPT Is Losing Users but Sending More Traffic to the Web. Here’s What That Means for Your Brand
The buzz around GEO has quietened in 2026 as the major AI platforms have shifted priorities. But the data tells a much more interesting story than the hype cycle suggests, and it matters if you’re an eCom leader.
We dug into both Semrush’s clickstream data and a citation study from SEJ from the last 18 months to understand what’s actually happening with ChatGPT traffic, and the picture is counterintuitive.
The Traffic Paradox
ChatGPT’s total user base peaked around October 2025 at roughly 650 million, then declined by around 10% through to February 2026. Gemini 3 was launched in November, which matches this decline.
But referral traffic - the visits ChatGPT sends out to the rest of the internet has done the opposite. It climbed from around 50 million monthly visits in late 2024 to nearly 290 million by early 2026. And it’s still accelerating.
Fewer users. More outbound traffic. That’s the paradox.
This suggests the product is shifting from a destination to a more pass-through/research tool for its engaged base.
Fewer Searches, More Clicks
It gets stranger. The share of ChatGPT prompts that trigger a web search has fallen from a peak of around 54% in September 2025 to roughly 28% by February 2026.
There are two ways to read this:
Either each search-enabled session is converting harder ie users are clicking through more when links appear or
ChatGPT is increasingly driving brand + web discovery without searching at all, recommending brands + sites from its own knowledge and shaping what users go to next.
Either way, the implication is the same: visibility inside AI responses matters whether or not a web search was triggered to generate that response.
Our read: ChatGPT is shedding its casual users. The ones who treated it as a novelty or a quick-answer tool. The users who remain are research-heavy, intent-rich, and more likely to follow a citation out to a website. The product is shifting from a destination to a pass-through discovery layer.
The Citation Surface Is Shrinking
In addition to all the data above, the number of cited domains per response has dropped by roughly 20% over the past few months.
That means fewer websites are competing for visibility inside each ChatGPT answer.
An SE Ranking analysis of 129,000 domains found that referring domains were the strongest predictor of ChatGPT citation likelihood, with a threshold effect kicking in at 32,000 referring domains (backlinks or digital pr links).
What This Means For Retailers
Retail remains one of the lowest industries for ChatGPT referral traffic. But the trajectory matters more than the current volume.
Conclusion: Despite the User Hit, ChatGPT Continues to Become a Brand Discovery and Trust Layer
Two things are happening in that journey: discovery and trust-building.
If your brand isn’t surfacing in AI responses, you’re missing the top of a new funnel.
If it is, users are likely heading to Google next to confirm, which means your organic presence needs to back up whatever ChatGPT is saying about you.
A reference from GPT can completely bypass the remaining funnel, taking users from discovery to purchase. An experience called anchoring bias.
What To Do Now
Treat GEO as a brand discovery channel. Every investment you make in SEO across authority building, content quality, and structured data is also what drives visibility in AI answers across ChatGPT, Google’s AI Overviews, and Gemini. This isn’t an either/or.
Get your product data ready for the agentic web. The next phase is AI agents that shop, compare, and transact on behalf of users. If your product feeds, attributes, and structured data aren’t clean and complete, you won’t exist in this upcoming (more commercial) AI world.
Don’t wait for the volume to arrive before you start optimising. The citation surface is shrinking now. The brands that build authority and visibility in AI responses today will be the ones capturing referral traffic at scale when it hits your category.
