  The Ultimate Guide to Being Cited by Google AI Overviews, ChatGPT, Perplexity & Gemini In 2025, getting ranked on page 1 of Google is no longer enough. You now need to be the source that AI engines cite in their answers. Google’s AI Overviews already appear on more than 17-25 % of queries (depending on region), Perplexity is growing 300 % YoY, and ChatGPT Search is live.
