Google Lost 10% of Search Share. Where Did It Go?

For the first time since 2015, Google's global search market share dropped below 90% (StatCounter, March 2025). In the US, the picture is even more dramatic.

According to SparkToro and Datos' Q4 2025 State of Search Report, Google's share of US searches fell to 73.7% when you count all the places people actually search - including ChatGPT, YouTube, Amazon, Reddit, and Perplexity. That is down from 77.1% at the start of 2025.

Where the searches went

The missing share did not go to Bing. It went to AI. ChatGPT alone has over 800 million weekly active users as of October 2025, up from 200 million just 14 months earlier. Perplexity raised $500M and processes hundreds of millions of queries monthly.

Google itself acknowledged the shift by launching AI Overviews - AI-generated answers that appear above traditional search results. Even Google knows that users want answers, not links.

What this means for local businesses

When Google served 10 blue links, there were 10 chances to be seen. When AI gives a direct answer, there are one or two chances. The math is brutal: fewer recommendations per query means each recommendation is worth exponentially more.

Search Engine Land reported that Google searches per US user fell nearly 20% year over year. Those queries did not disappear. They moved to AI platforms where the answer format is completely different.

The two-front problem

Local businesses now face a two-front challenge. You still need to rank on Google - it remains the largest single search platform. But you also need to be visible to ChatGPT, Gemini, Claude, and Perplexity, which are absorbing a growing share of the queries that used to go to Google.

The signals for each are different. Google cares about backlinks, page speed, and keyword relevance. AI engines care about structured data, review sentiment, directory accuracy, and answer-format content.

You can rank #1 on Google and still be invisible to ChatGPT. We see this regularly in our AEO scans. The businesses that understand this now will have a structural advantage as the shift accelerates.
