ChatGPT vs. Google: How Many “Searches” Happen Per Day?

Overview

The core objective of every SEO strategy is visibility. For years, that meant optimizing primarily for Google. But what if a growing share of searches are now happening somewhere else?

Generative AI platforms like ChatGPT are increasingly being used to find answers. While many SEOs still view AI search trends as something to monitor later, the data suggests it's a much more urgent shift.

If a significant amount of searchers are turning to AI platforms instead of traditional search engines, it could have major implications for visibility, traffic, and ultimately revenue.

To understand just how big this change might be, our data science team analyzed current usage patterns, reviewed the latest public data, and built a model to estimate ChatGPT’s daily query volume compared to Google’s. The results shed light on shifting user behavior and what it means for the future of search.

Why Understanding ChatGPT’s Search Volume Is Critical

Generative AI tools like ChatGPT aren’t just for content creation. They’re increasingly being used to answer questions and deliver information, stepping into territory once dominated by traditional search engines.

For SEOs and marketers, understanding how much of this “search-like” activity is happening on ChatGPT versus Google isn’t just interesting, it’s essential.

It can help you:

Spot shifts in user behavior before they impact your traffic
Adapt your visibility strategy across both classic and AI-driven search experiences
Stay ahead of the competition as attention moves beyond the SERP

The search landscape is evolving fast. Knowing where users are asking questions today is key to being found tomorrow.

What We Know About ChatGPT Usage

Recent statements from OpenAI provide valuable insight into ChatGPT’s scale:

~700 million weekly active users across all ChatGPT products (Free, Plus, Enterprise, Team, and Edu)
Over 3 billion messages per day sent by users

However, it’s important to note: not all of these messages are “search-like” in nature. Many prompts are used for tasks like writing, planning, coding assistance, or brainstorming, rather than information retrieval.

How We Estimated ChatGPT’s Daily “Search-Like” Activity

To compare apples-to-apples with Google, we built a model to estimate how many ChatGPT prompts function similarly to search queries.

Our estimate is based on three key inputs:

Total Daily Prompts: Based on OpenAI’s disclosures, we modeled a range of 2.5 to 3.0 billion prompts per day.
Percent of Prompts with Search Intent:

- 77 percent of ChatGPT users in the U.S. report using it “as a search engine” at least occasionally.
- 57 percent of workplace chatbot users use them for “research” tasks.

From these, we modeled three scenarios to estimate the percent of ChatGPT prompts that have search intent: Low = 40%, Base = 55%, High = 70%.

3. Prompts Per Search Task: Some queries are answered in a single prompt; others involve follow-ups. We assumed 1.2 to 1.4 prompts per task to reflect this variation.

Our Formula:

This approach gives us a comparable measure to traditional search engine queries, shedding light on how much of today’s search activity may be happening outside of Google.

The Results: Number of ChatGPT “Searches” Per Day

Based on our model, here’s how ChatGPT’s daily “search-like” activity stacks up under the three different scenarios we mentioned previously:

Scenario	Daily Prompts	% Search Intent	Prompts/Task	Estimated ChatGPT Searches/Day	Share of Google’s Daily Searches*
Low	2.5B	40%	1.4	0.71B	5.3%
Base	2.8B	55%	1.3	1.18B	8.7%
High	3.0B	70%	1.2	1.75B	12.9%

Note: Google’s daily searches are estimated at 14–16.4 billion, based on its disclosure that it processes over 5 trillion searches per year.

What ChatGPT’s Search Volume Signals About the Future of Information Discovery

Even using a conservative model, ChatGPT is already handling nearly 1 in 10 of the “search-like” activities that Google does every day. At the high end, it’s over 1 in 8.

That’s a remarkable milestone for a product that launched less than three years ago — and a clear signal that information discovery is no longer confined to traditional search engines.

Research Methodology

Estimates are based on publicly disclosed usage statistics from OpenAI (daily prompt volume), Google (annual search volume), and third-party surveys on ChatGPT usage intent (Adobe/TechRadar, Pew Research).

We modeled three scenarios—conservative, base, and aggressive—using varying assumptions for search intent (40–70%) and prompts per task (1.2–1.4). This approach enables a directional comparison of ChatGPT’s “search-like” activity relative to Google’s daily searches, highlighting emerging trends in user behavior.
