Is ChatGPT Replacing Google? What the Search Data Shows and What to Report to Clients

If you run an agency, a client has probably forwarded you a version of this already. A chart doing the rounds says ChatGPT has "outranked Google as a search destination", and underneath it is the question they actually want answered: are we still paying for the right thing? So, is ChatGPT replacing Google? The short answer is no, and the longer answer is more useful, because it tells you exactly what to add to your reports.

This post goes through what that chart shows, what the better-documented research says, and how to turn it into a section of the client SEO report that answers the question before the next call.

The chart everyone shared

The image came from a Semrush post promoting the State of Search Q2 2026 report, which Datos (a Semrush company) produced with SparkToro's Rand Fishkin from clickstream data across the US, EU and UK. The headline reads that ChatGPT has outranked Google as a search destination. The small print underneath is more careful: it says ChatGPT climbed to number 7 among sites people visit after a search, and Google dropped out of the top 15.

That caption is the whole story. It is a list of destinations, the sites people land on once they have searched for something. Google is a search engine, so it is an odd thing to find on a list of places people go after searching, and its absence says little about how many searches it handles. The same post lists findings that point the other way: traditional search is still going strong as AI use grows, and people are asking longer, more detailed questions. The full report sits behind a download form, so treat the headline as a summary of one chart, not a verdict on search.

Is ChatGPT replacing Google? What the data actually says

The most useful published numbers come from Semrush itself. Its ChatGPT clickstream study, published in April 2026, followed US desktop and mobile sessions in a 200 million user panel from October 2024 to February 2026. Two findings matter for agencies.

First, ChatGPT is not mostly a search engine. It turned on web search for just 34.5% of prompts in February 2026, down from 46% in late 2024. Most of what people do in it is writing, explaining, planning and coding, not looking things up.

Second, when ChatGPT does send people somewhere, the top destination is Google. Google accounted for 21.6% of all ChatGPT referral traffic by February 2026, up from about 14% at the start of the study. People read an answer, then go and check it, or go and find the brand they just heard about. Semrush's own survey found most people use AI and traditional search together, and Semrush's Eli Goodman put it plainly: "we're watching it expand."

Why "ChatGPT beat Google" is the wrong read

It is easy to see why the headline travelled. It confirms what a lot of people already suspect, and there is a real trend underneath it: AI assistants are a growing way to find things. But "ChatGPT is now a place people go" and "ChatGPT is replacing Google" are different claims, and only the first is supported.

For a client, acting on the wrong one is expensive. Cutting SEO because of a chart would mean walking away from what is, for most clients, still their largest source of search traffic, and the place ChatGPT itself sends people back to. The better response is to keep the Google work and start measuring the AI side properly, so decisions rest on the client's own numbers rather than a screenshot.

What to report to clients now

The useful version of the question is not whether ChatGPT is replacing Google in general, but whether it is for this client. You can answer "is ChatGPT replacing Google for us?" with the client's own data, and it takes three sections.

Google organic, as before. Search Console clicks, impressions and average position, with rankings for the terms that matter. Note that Google counts AI Overviews and AI Mode inside the normal Web results in Search Console rather than breaking them out, so these numbers already include Google's AI features.

AI assistant visits. Since 13 May 2026, GA4 files visits from ChatGPT, Gemini, Claude and similar tools in a dedicated AI Assistant channel, with the medium ai-assistant, as set out in Google's default channel group definitions. Report sessions, engagement and conversions from that channel, compared with the previous period. For most clients the number will be small. That is the point: it shows the real scale next to the hype.

AI visibility. Clicks are only part of it, because many AI answers mention a brand without sending a visit. AI visibility tracking checks how often the client is mentioned or cited in ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews for the questions their customers ask, and how that compares with competitors. That is the number that moves first when the content work is going in the right direction.

Put the three together and the client sees where they actually stand. In AgencyReportr, a marketing reporting tool for agencies, all three live in the same white-label SEO report, next to daily keyword rankings, so nobody has to stitch screenshots together before a meeting.

How to talk about it on a client call

Keep it simple and use their numbers. Something like: "Google still sends most of your search traffic, and it is holding steady. AI assistants sent you this many visits last month, up from last month, and they converted at this rate. You are mentioned in this share of the AI answers we track, and here is our plan to raise it." That answers the worry, shows you are on top of the new channel, and keeps the conversation on results rather than headlines.

If a client still wants to shift budget, agree a test with a clear measure, such as content written to win AI citations for a set of questions, reviewed after a quarter. Then the next report settles it.

ChatGPT vs Google FAQ

Is ChatGPT replacing Google?

Not on the evidence published so far. Semrush's own clickstream study found Google is the top destination of ChatGPT's outbound clicks, at 21.6% of ChatGPT referral traffic in February 2026, and most people surveyed use AI tools and traditional search together.

What does the chart saying ChatGPT outranked Google actually measure?

Its own caption describes a ranking of sites people visit after a search. That is a list of destinations, not a measure of where searches happen, so it does not show ChatGPT handling more searches than Google. The full Datos report behind it is gated.

How do I see ChatGPT traffic in a client's Google Analytics?

Since 13 May 2026, GA4 puts visits from AI assistants such as ChatGPT, Gemini and Claude into a dedicated AI Assistant channel with the medium ai-assistant. Google AI Overviews and AI Mode are not in it; those visits stay in Organic Search.

Should agencies move budget from SEO to AI search?

Not wholesale. For most clients Google is still the largest source of search traffic, which their own Search Console and GA4 will show, and AI assistants often send people back to Google. Add AI visibility to the reporting and the content plan alongside SEO rather than instead of it.

What should a client report show about AI search?

Three things: Google organic performance from Search Console, AI assistant visits and conversions from GA4, and AI visibility, meaning how often the brand is mentioned or cited in tools like ChatGPT, Gemini and Perplexity for the questions its customers ask.
