Google’s AI Overviews Reach 2 Billion Users—Is Traditional SEO Dead

Google has just revealed that its AI Overviews—those AI-generated summaries that appear at the top of search results—are now serving over 2 billion users each month. This massive leap highlights not only the growing reliance on artificial intelligence in everyday search behaviour but also a major turning point for the digital content and SEO ecosystem. In parallel, the company’s AI Mode, a conversational search assistant designed to engage users more like a chatbot than a traditional search engine, has already surpassed 100 million monthly users in the United States and India combined.

These developments were announced as part of Alphabet’s Q2 2025 earnings call, during which CEO Sundar Pichai emphasised the company’s strategic focus on integrating AI across all search experiences. The numbers are staggering: over 10% of search queries now return an AI Overview, and the rollout continues to expand globally with support for more than 40 languages across over 200 countries. More importantly, AI Mode is no longer experimental—it’s becoming a mainstream feature with daily engagement figures that rival some of Google’s most used legacy products.

But this AI-led future is raising critical questions for publishers, creators, and marketers. Recent analysis shows that search results with AI Overviews see a dramatic decline in click-through rates—dropping from an average of 15% to just 8%. This means that the vast majority of users no longer click through to websites when AI answers their questions upfront. For many content creators who depend on Google search traffic, this shift could be deeply disruptive. The traditional SEO model—ranking on page one, earning clicks, and monetizing through ads or products—is increasingly being bypassed by Google’s own AI-powered answers.

Why This Shift Matters for SEO

1. Traffic Redistribution

   • Results featuring AI Overviews see only an 8% click-through rate, compared to 15% when absent.

   • That means 92% of users don’t click through after reading the overview, potentially starving publishers of clicks.

2. SEO Value Under Pressure

   • More than 10% of relevant searches now show AI Overviews, with growing usage over time.

   • The challenge: your ranking might not bring traffic if the Overview answers the user’s query directly.

3. Paid Search & Monetization

   • Google confirmed that AI Overviews monetize “at the same rate” as traditional search.

   • They plan to roll out ads within AI Mode soon in the U.S.—a pivot toward ad-supported AI

In an attempt to reassure stakeholders, Google stated that it is monetising AI Overviews at a similar rate to traditional search, with plans to introduce sponsored listings within AI Mode. This implies that businesses will soon be competing for visibility within AI-generated responses, not just organic listings. The monetization model is evolving fast, and early adopters may have a first-mover advantage if they learn how to optimize their content and advertising strategies for these new formats.

For website owners and SEO professionals, this changing landscape demands a new playbook. Structured data has never been more important, as Google’s AI needs clean, well-organized content to parse and summarize effectively. Optimizing for featured snippets, using schema markup, and clearly structuring content with bullet points, FAQs, and lists can help increase the chances of being included in Overviews. Long-tail keywords and deep topical coverage are also becoming essential, as these types of queries are less likely to be fully answered by a one-paragraph AI summary.

Meanwhile, businesses are being urged to diversify their traffic sources. Relying solely on organic Google search could become risky if AI increasingly cannibalizes those clicks. Newsletters, social media, podcasts, and direct community engagement can help brands maintain visibility in an AI-first search world. Companies that invest in their own ecosystems—be it through loyal subscribers, mobile apps, or membership platforms—will be better positioned to weather the storm.

It’s also worth noting that Google isn’t alone in this race. Microsoft’s integration of OpenAI into Bing, Amazon’s rumoured AI shopping assistant, and Apple’s upcoming AI enhancements all point to a competitive landscape where AI answers, not blue links, dominate. This makes it even more crucial for content creators to adapt quickly, experiment with new formats, and keep a close eye on how search behaviours evolve in real time.

As Google celebrates the growth of AI Overviews and AI Mode, it’s clear that the future of search is no longer about what users type, but what answers they get—and who controls the narrative. For content creators, brands, and SEO strategists, this is both a wake-up call and a unique opportunity. The next phase of search won’t just be about ranking. It will be about training, structuring, and positioning your content to become the source that AI trusts—and users rely on.
