ChatGPT vs Google: What the "One-Fifth of Search" Claim Means

What OpenAI said

The claim came at an OpenAI dinner in New York on the evening of 2 November 2026. Adam Fry, who leads ChatGPT's consumer product, said search-like queries on ChatGPT are "roughly one-fifth the volume of queries of Google." He defined search as "basically anything that a user would have traditionally gone to a traditional search engine for." He also said ChatGPT had grown from one billion to 1.2 billion weekly users in two months, as 24/7 Wall St. reported.

Three things were missing: the Google number being compared against, the time period, and the region. OpenAI is a private company and does not publish query data, so the figure cannot be checked. That does not make it wrong. It does mean it is best read as a direction (ChatGPT is big and growing) rather than a measurement.

ChatGPT vs Google search: the numbers

ChatGPT vs Google: volume, users and traffic, as of November 2026

Why the estimates differ so much

The answer depends almost entirely on one question: which ChatGPT prompts count as searches? ChatGPT is used for many things people never did on Google, such as drafting emails, fixing code or brainstorming. Counting all of those as searches inflates the number. Counting only "look this up for me" questions shrinks it.

• Ahrefs, broad (about 12%). In February 2026, Patrick Stox started from OpenAI and Harvard research on 1.5 million conversations, then counted everything people would traditionally have searched Google for, including translations and calculations. That came to about 65% of ChatGPT prompts, or about 1.6 billion a day: 11.86% of Google's volume.
• Ahrefs, pure search (4.4%). Counting only the 24% of prompts that are straightforward information requests (facts, products, recipes) gives about 600 million a day.
• seoClarity (3% to 8%). Its September 2025 model also adjusts for the fact that one search task in ChatGPT often takes more than one prompt, which brings the estimate down to about one billion search-like tasks a day.
• OpenAI (about 20%). Fry's definition, "anything a user would have gone to a search engine for", is close to the broad end. OpenAI also has newer user numbers than the outside estimates, which use 2025 data.

None of these is a measured ChatGPT market share. They are models. The honest summary is that ChatGPT's search-like activity is somewhere between a few percent and a fifth of Google's, and growing.

Searches are not traffic

This is the number that matters most for most businesses. Even at 12% of Google's search volume, ChatGPT sent a tiny share of visits to websites. Across 76,000 sites in Ahrefs' data, Google accounted for 39.98% of all traffic and ChatGPT for 0.21%. Google sent about 190 times more.

The reason is how each product works. Google shows a list of pages; people click. ChatGPT writes the answer itself and only sometimes searches the web. Semrush's clickstream data, covering a 200-million-user US panel, found ChatGPT ran a web search on 34.5% of queries, down from 46% in late 2024. Fewer searches mean fewer sources and fewer links to click.

Two more Semrush findings stand out. The biggest single destination for clicks out of ChatGPT is Google itself, with 21.6% of all ChatGPT referrals: people check, compare or buy on Google after asking ChatGPT. And ChatGPT referral traffic did grow fast, by 206% between January 2025 and January 2026, though from a small base and with growth levelling off.

The takeaway is not that ChatGPT does not matter. It is that its value shows up in a different place. When ChatGPT answers "which accounting software should a small agency use?", the buyer may never visit a website, but they leave with a shortlist. Whether your brand is on it is the new question, and our article on why ranking on Google doesn't get you recommended by AI covers how that shortlist forms.

Is Google shrinking?

No. By Google's own figures, it is growing faster than it has in years. On its Q3 2026 earnings call on 28 October, Google said year-on-year query growth was "the highest it's been in the last five years", including commercial queries, and Search revenue rose 12%. Queries in AI Mode are on average three times longer than traditional searches, and Google handles more than 50 billion visual searches a month.

What is changing is the shape of Google, not its size. AI Overviews now appear on more than 80% of searches, according to Search Engine Roundtable, and they reduce clicks to websites. Google has also said AI Mode earns less revenue per query than classic search. So the same forces that make ChatGPT a "zero-click" product are now at work inside Google as well. Our guide to Google's October AI search update covers what Google is doing to put links back into its AI answers.

Will ChatGPT replace Google?

Not on current data. Both are growing, and people use both. ChatGPT reached about 1.2 billion weekly users by September 2026, and Forbes reported on 5 November that India has become its largest market by weekly users. Google's Gemini app passed one billion users. Meanwhile, the largest share of clicks out of ChatGPT goes to Google.

Framing it as Google vs ChatGPT misses how people actually use them. A better way to think about it: search has split into two habits. People still go to Google to find a specific site, check a price, see local options or buy. They increasingly go to ChatGPT, or to AI Mode inside Google, to think through a decision: "what should I consider", "which is better for me", "explain the difference". The second habit is where brands are compared and shortlisted, often without a click.

What it means for marketers

1. Do not move budget based on the 20% headline. Google still drives most website traffic and most search ad revenue. Query volume in ChatGPT does not turn into visits at anything like the same rate.
2. Measure visibility, not just visits. In AI answers, a brand can be recommended, described wrongly or left out without any click happening. Traffic reports will not show any of this. You need to check the answers directly.
3. Track both places, on the same questions. Ask the same buyer questions in Google (including AI Overviews and AI Mode) and in ChatGPT, Gemini and Perplexity. The brands named will often differ.
4. Build what AI assistants use. Brand mentions across the web, accurate reviews and comparison listings, and clear, specific pages. Strong SEO is still the base, since many AI answers draw on search indexes. Our LLM SEO guide explains the differences.
5. Watch AI ads as a new channel. ChatGPT ads are now sold in 89 markets, including India, where they start from ₹725 a day. Our article on ads inside AI assistants covers what this means for earned visibility.
6. Look at your markets one by one. ChatGPT's growth is uneven by country, and AI answers differ by market. The multi-country tracking article shows how much.

Frequently asked questions

How many searches does ChatGPT get compared with Google?

It depends on what counts as a search. OpenAI said on 2 November 2026 that ChatGPT handles roughly one-fifth of Google's query volume, without giving a baseline. Ahrefs estimated about 12% using a broad definition and 4.4% counting only pure information searches; seoClarity modeled 3% to 8%. Google handles about 13.7 billion searches a day.

What is ChatGPT's market share of search?

There is no measured figure, because OpenAI does not publish query data and not every prompt is a search. Modeled estimates range from 3% to 12% of Google's volume, and OpenAI's own claim is about 20%. By traffic sent to websites, the gap is far larger: 0.21% for ChatGPT against 39.98% for Google in Ahrefs' data.

Does ChatGPT send traffic to websites?

Some, but much less than Google. Across 76,000 websites, ChatGPT sent 0.21% of traffic and Google 39.98%, about 190 times more. ChatGPT referral traffic grew 206% from January 2025 to January 2026, and Google itself received 21.6% of all ChatGPT referrals.

Will ChatGPT replace Google?

Not on current data. Google reported its fastest query growth in five years in October 2026, and Search revenue rose 12%. ChatGPT is growing too, to about 1.2 billion weekly users, but people use both, and Google is the biggest destination for clicks out of ChatGPT. Brands now need to be visible in both.

What is the difference between Google Search and ChatGPT?

Google shows a list of web pages, often with an AI Overview on top, and most people click through to a site. ChatGPT writes an answer and only sometimes searches the web: about 34.5% of queries, in Semrush's data. ChatGPT is also used for writing, coding and other tasks that are not searches, which is why it sends far fewer visits per question.

Should marketers move budget from Google to ChatGPT?

Not based on query volume alone. Google still drives most website traffic and search ad revenue. What has changed is that a growing share of buyer research happens inside AI answers, where brands are named or not without a click. Keep investing in Google, add tracking of how your brand appears in AI assistants, and act on the gaps.
