What This Data Reveals
Google AI Overviews is changing how search visibility works. Ranking in the top 10 is no longer enough, because citations now depend more on query fan-out, source diversity, and multimedia coverage.
🔥 The Massive Shift:
AI Overview citations from top-10 organic results dropped from 76% in July 2025 to 38% by February 2026. This shows Google is pulling from a wider source mix, not just top-ranking pages.
YouTube’s Dominance: YouTube became the most-cited domain in AI Overviews, with a 200x advantage over other video platforms. Video optimization is now essential.
