ChatGPT Sends 21% of Its Traffic to Google. Here's Why That Matters.

A new Semrush study — analysing over a billion lines of clickstream data across 17 months — has revealed something that changes how we should think about ChatGPT as a search channel: 21% of all ChatGPT referral clicks go straight to Google.

That's not a quirk. It's a pattern — and it's growing.

ChatGPT referral traffic to websites grew 206% year on year (January 2025 vs January 2026), even as ChatGPT's own traffic has plateaued near a billion monthly visits. The platform is no longer just a chatbot. It's becoming a doorway to the open internet — and Google is its biggest beneficiary.

But here's what makes this data so important for marketing leaders: ChatGPT is absorbing more and more of the research phase. Users are making purchase decisions inside their AI conversations before they ever click through to a website. If your brand isn't showing up in those conversations, you're invisible at the most critical point in the buyer journey.

In this episode, Dale Davies (Head of Marketing at Exposure Ninja) and Charlie Marchant (CEO of Exposure Ninja) break down the full Semrush report and explain what it means for your search strategy:

💡 Why 21% of ChatGPT's outbound clicks going to Google means your SEO foundation matters more than ever — not less

💡 The 206% year-on-year increase in ChatGPT referral traffic and why the "ChatGPT doesn't send traffic" objection is now dead

💡 How 30% of all ChatGPT referral traffic goes to just 10 domains — and what the remaining 70% means for your business

💡 Why only 35% of ChatGPT queries trigger a live web search (down from 46%) and what that means for how quickly your optimisation efforts show results

💡 The critical difference between ChatGPT prompts and Google keywords — and why your content strategy needs to account for both

💡 How to use your Google Analytics data to identify which AI platforms are actually driving referral traffic and conversions for your business

💡 Why businesses with clear positioning and well-defined customer personas will dominate in AI search — and why generic brands will struggle

As Charlie explains:

"ChatGPT is a new search channel. People are searching within ChatGPT. It's now part of the search journey to finally find the business or the product that they actually want. We need to optimise for all of the channels where we know that our customers are having touchpoints."

The businesses building their AI search strategies now — not waiting for the dust to settle — are the ones that will hold the advantage as ChatGPT's referral traffic continues to grow. This episode gives you the data and the framework to act on it.
