1.5 Billion People Use Google's AI Overviews Every Month

Google’s AI Overviews, which offer AI-generated summaries at the top of Search results, now reach over 1.5 billion users monthly across 100+ countries.

"In Search, we saw continued double-digit revenue growth. AI Overviews is going very well with over 1.5 billion users per month, and we’re excited by the early positive reaction to AI Mode. There’s a lot more to come," Alphabet CEO Sundar Pichai said in a blog post.

First introduced two years ago, the feature continues expanding into new regions and languages. While it has raised concerns about reduced publisher traffic, Google views AI Overviews and similar tools as key to boosting engagement and revenue.

Ads were introduced in AI Overviews last October, and more recently, the company began testing “AI Mode,” enabling users to ask complex, multi-part questions in a chat-like experience.

On its Q1 2025 earnings call, Google also highlighted growth in other AI-powered search features. Circle to Search, now available on 250 million+ devices, saw a 40% increase in usage over the last quarter.

Visual search through Google Lens also gained traction, with 5 billion more searches since October and a 10% rise in shopping activity during Q1.

Advertising remained Alphabet’s largest revenue stream in Q1 2025, bringing in $66.8 billion, up 8.5% from the same quarter in 2024 and slightly above the $66.4 billion forecast.

Within the segment, “Google Search & Other” delivered $50.7 billion in revenue, a 9.8% increase from $46.16 billion last year. YouTube advertising brought in $8.93 billion, representing a 10.3% year-over-year rise, just under analyst estimates of $8.97 billion.

Recently, Perplexity CEO Aravind Srinivas revealed that the startup wants to follow Google's footsteps and start collecting users' data to sell hyperpersonalised ads. Interestingly, once, new age GenAI startups like Perplexity were positioned as 'Google Killer'.

Speaking on the TBPN podcast, Srinivas said that collecting data beyond Perplexity’s app is key to offering more relevant advertising and content recommendations.

“That’s kind of one of the other reasons we wanted to build a browser—we want to get data even outside the app to better understand you. Because some of the prompts that people do in these AIs is purely work-related… what you’re buying, which hotels or restaurants you visit, what you spend time browsing—tells us so much more,” Srinivas said.
