To discover this query, we analyzed how individuals interacted with Google Search after their first ChatGPT interplay. 

Our findings revealed an fascinating sample: ChatGPT adoption isn’t decreasing Google utilization—it’s increasing the way in which individuals search.

Two Hypotheses: Substitution vs. Growth

The research was deliberate to substantiate one in all two theories that would clarify what’s taking place now:

• Substitution Speculation: ChatGPT adoption pulls customers away from Google Search. Folks “substitute” ChatGPT for the way they beforehand used Google. 
• Growth Speculation: ChatGPT adoption doesn’t scale back Google utilization. In different phrases, it merely expands total information-seeking habits.

Methodology 

We analyzed 260 billion rows of clickstream knowledge between January 2024 and June 2025 to check the Google Search habits of usersbefore and after their first interplay with ChatGPT. 

Be aware: This clickstream knowledge set is predicated on an anonymized pattern of distinctive customers (panelists) who opted in to share their searching habits. This methodology lets us perceive on-line developments at scale—whereas maintaining particular person privateness totally protected.

To grasp if (and the way a lot) Google Search exercise modified after individuals began utilizing ChatGPT, we monitored the variety of search periods from every person three months earlier than and after their first ChatGPT session.

• Examine group: U.S. customers who started utilizing ChatGPT in Q1 2025, with no prior ChatGPT exercise in 2024.
• Management group: Customers who by no means used ChatGPT throughout 2024–2025. This was our baseline for understanding how Google utilization may change naturally over time (with out ChatGPT adoption).
• Platform & location: Desktop units within the U.S. solely, permitting for constant session monitoring.
• What was measured: Google Search periods 90 days pre- and post-ChatGPT adoption.

This method helped us assess whether or not ChatGPT adoption results in a change in conventional search habits, or whether or not it corresponds with steady and even rising search exercise.

Complete Search Habits Expands with ChatGPT Utilization

Based mostly on the information, ChatGPT adoption didn’t scale back Google Search utilization. 

This helps the enlargement hypotheses, which means individuals didn’t substitute their typical Googling with ChatGPT-ing.

In truth, there was even a slight improve in common Google Search utilization after ChatGPT adoption.

Even regardless of sustained ChatGPT utilization after adoption, Google Search utilization remained fixed. 

January 2024 Cohort

These conclusions had been additionally true for an extended cohort: those that began utilizing ChatGPT in January 2024.

For this cohort, we tracked their habits for 500 days and noticed the same sample of sustained Google utilization, together with steady ChatGPT utilization after adoption.
