What we learned from analyzing one billion keywords?

The team at Serpstat just published one of the most in-depth studies to date on Google’s AI Overviews — the generative AI answers now appearing in search results. By analyzing 1 billion keywords and 35 million AIO blocks, they uncovered how AI is reshaping organic visibility.

Key takeaways for marketers and founders:

—AIO is growing fast: In just 12 months, AIO blocks jumped from near-zero to appearing in 27% of SERPs.
—Long-tail wins: Queries with 10+ words are 3x more likely to trigger an AI response.
—Organic SEO ≠ AIO: 90% of AIO citations come from outside the top 20 organic results — traditional rankings don’t guarantee AI visibility.
—UGC platforms dominate: Google favors content from Reddit, YouTube, Quora, and authoritative health sites.
—Desktop leads rollout: AIOs appeared on desktop 5 months before mobile — a sign Google tests AI features in stages.

One standout insight: When AIO does cite organic pages, it overwhelmingly favors the top 5 positions — reinforcing the value of ranking high, even as AI rewrites the rules.

For solo founders, marketers, and indie creators, this means:
🛠 Build content for complexity.
📹 Prioritize video and community-driven content.
🧠 Think beyond the top 10 — authority matters more than rank.
