Google's AI Overviews have driven organic search traffic down 42% since their rollout. That's the headline finding from a Define Media Group study published March 12, based on Search Console data across 64 websites.
Traffic never recovered after the initial launch. And Google's expansion of AI Overviews in May 2025 made things worse.
The numbers
Before AI Overviews, the portfolio averaged 1.7 billion clicks per quarter. Here's the timeline:
- AI Overviews launch — immediate 16% drop
- May 2025 expansion — decline accelerated
- Q4 2025 — down 42% from pre-AI Overviews baseline
But not everything is falling. Breaking news traffic surged 103% between November 2024 and March 2026. Google Discover grew 30% and now drives roughly as much traffic as traditional search for these publishers.
Why news content survives
AI Overviews appear on about 15% of news queries — compared to 45% for topics like health and science, according to Ahrefs data cited in the report.
The reason is straightforward. Breaking events change fast, accuracy stakes are high, and generative systems still hallucinate. Google defaults to the Top Stories carousel, which links directly to publisher articles.
What this means for businesses
If you rely on evergreen content to drive traffic, this study is a wake-up call. "How to" guides and informational articles are the hardest hit — Google answers directly, users don't click through.
Three channels are gaining value instead:
- Timely content — covering industry news with fresh data that AI can't generate on its own
- Google Discover — a growing channel that favors engaging editorial content
- Deep niche expertise — content so specific that AI can't summarize it without losing the value
Our take
At Cicero, we've been saying this since AI Overviews launched: SEO isn't dying, it's mutating. Generic content is done. What survives — and what will dominate — is content that brings something AI can't manufacture: proprietary data, hands-on expertise, a sharp editorial angle.
A 42% drop is massive. But a 103% surge in news traffic is an opportunity for those who move now.
