ChatGPT is growing to become a key part of how people understand things and look for answers online. Yet for all the attention it receives, one basic question is still a bit murky for marketers and business leaders: how many “searches” does ChatGPT actually handle compared to Google?
The difficulty in finding this data is simple. ChatGPT does not publish traditional search figures, and its usage patterns are not the same as a search engine. People use it for much more than just “searching for stuff”. What we can do, however, is work from reliable public data and state clear assumptions to form a grounded comparison.
Why This Question Matters
Google has defined online search behaviour since the early 2000s. The emergence of ChatGPT and other LLMs has opened the avenue to other types of search-like activity, with millions turning to conversational tools to ask questions, gather information or get advice.
But usage alone does not answer the core question, as people use ChatGPT in more ways than just as a search engine. The task here is to understand how many ChatGPT interactions resemble the same or similar intent behind a Google query.
Step One: Understanding ChatGPT Usage
Step Two: Estimating ChatGPT Search Volumes
Step Three: Understanding Google’s Search Volumes
Step Four: Comparing ChatGPT vs Google Monthly Searches
Step One: Understanding ChatGPT Usage
ChatGPT dominates the AI assistant space, holding 81.84% market share as of November 2025. This already shows its reach, but market share does not translate directly into volumes. Just because lots of people are using ChatGPT, it doesn’t mean they are all using it to conduct “Google equivalent” activity.
To estimate volumes, we need to understand what users are actually doing when they use ChatGPT.
In September 2025, OpenAI and the National Bureau of Economic Research released the largest usage study so far. It examined 1.5 million conversations from 130,000 users and gave detailed insight into how people interact with ChatGPT. The image below shows a summary of use.
Conversation topics were broken down into seven categories: Writing, Multimedia, Seeking Information, Self-Expression, Practical Guidance, Technical Help and Other/Unknown.
Out of these, two categories were especially relevant:
- Seeking information (21.3% of conversations)
- Practical guidance (28.3% of conversations)
Analysing all of the categories and sub-categories, these are the sub-categories that closely match common Google behaviour.
- Practical guidance – How to advice: 8.5%
- Practical guidance – Health, fitness, beauty or self-care: 5.7%
- Seeking information – Specific information: 18.3%
- Seeking information – Purchasable products: 2.1%
- Seeking information – Cooking and recipes: 0.9%
Our assumption in creating this data is that these categories were treated as the closest equivalents to Google-style searches. Together they add up to 35.5% of ChatGPT conversations.
So, to summarise, only 35.5% of conversations in ChatGPT closely match Google equivalent style searches.
Step Two: Estimating ChatGPT Search Volumes
Public statements from Sam Altman provide the basis for estimating daily volumes:
- December 2024: ChatGPT was processing over 1 billion messages per day
- July 2025: Reports indicated around 2.5 billion messages per day
- October 2025: ChatGPT reached 800 million weekly active users
If we use the 2.5 billion daily messages figure in our calculation:
2.5 billion daily messages × 35.5% = 887.5 million “Google-equivalent” chats per day.
This figure counts only the portion of prompts that align with the types of searches people typically ask Google.
It is important to stress that this is not a claim that ChatGPT is functioning as a search engine in the same way. It is simply a conversion based on the estimated share of prompts that resemble Google-style intent.
Step Three: Understanding Google’s Search Volumes
In March 2025, Google confirmed that it handles more than 5 trillion searches per year. Breaking that down gives us the following:
- Around 14 billion searches per day
- Around 417 billion searches per month
To understand ChatGPT’s presence in the information space, we need to see it in context of this scale.
Step Four: Comparing ChatGPT vs Google Monthly Searches
Putting both sets of figures next to each other gives a clear comparison:
- Google daily searches: circa 14 billion
- ChatGPT “Google-equivalent” daily prompts: circa 887.5 million
This means that:
Google handles 15.77 times more searches than ChatGPT per day.
Or expressed as a percentage:
ChatGPT handles around 6.3 percent of Google’s monthly search volume.
| Google daily searches | ChatGPT equivalent daily prompts | Ratio of Google:ChatGPT | ChatGPT percent search volume compared to Google |
|---|---|---|---|
| 14 billion | 887.5 million | 15.77 : 1 | 6.3% |
What These Figures Tell Us
They Tell Us:
- ChatGPT processes enormous volumes of chats every day, but only around a third resemble intent similar to Google searches.
- Google’s scale remains far beyond any AI assistant.
- ChatGPT is significant enough to influence user behaviour, but nowhere near displacing Google in sheer volume.
However, They Do Not Tell Us:
- How these numbers may change in the future based on the future growth rate of ChatGPT and Google.
- How many of these ChatGPT queries lead to actions such as purchases, visits or citations.
- How often ChatGPT is used as a substitute for a Google query rather than a complement.
- How many prompts come from the same user repetitively, which may inflate totals.
So Is ChatGPT Replacing Google?
ChatGPT volumes are large enough to influence user behaviour, but the data does not support the idea that it is replacing Google. In fact, research published by Semrush shows the opposite.
After users adopt ChatGPT, their Google usage does not decline. Instead, people simply start using both tools for different reasons. ChatGPT becomes an extra step in how they gather information, not a substitute for traditional search.
Before the study cohort used ChatGPT, they had an average of 10.5 Google search sessions per week. After using ChatGPT, this increased to 12.6 Google search sessions per week.
This is an important distinction. ChatGPT adds another layer to online research. People turn to it for explanations, summaries, ideas or initial direction, then continue to use Google for verification, product checks, local information, source reviews and deeper investigation.
One user described it as: “When I want to know something, I use ChatGPT. When I want to find something, I use Google”.
Put simply, ChatGPT is expanding search behaviour, not reducing it.
For marketers, this means visibility is now split across two fronts. Google continues to hold the largest share of search activity by a wide margin, but ChatGPT introduces a parallel space where answers are given directly and websites are often not visited.
Understanding the scale of both platforms helps shape strategies that account for where users begin, where they compare, and where they end up.
Final Thoughts
Comparing ChatGPT and Google is not a measure of who is winning, but a way of understanding how information-seeking behaviour is evolving.
Under the clearest available figures, Google still receives 15.77 times more searches daily. Yet ChatGPT’s share is not trivial. Hundreds of millions of daily prompts fall into categories that mirror classic search intent. As more users mix search and AI assistants, the question is not whether one will replace the other, but how your brand can be found in both.
