Three AI Search Engines, Three Strategies: How ChatGPT, Google, and Perplexity Cite Sources

🔍 Three AI Search Engines — Three Citation Strategies

A Leapd study analyzed 680 million citations from ChatGPT, Google AI Overviews, and Perplexity.

ChatGPT — Wikipedia (7.8%) and training data. Google AI Overviews — Reddit (2.2%) and LinkedIn (1.3%). Perplexity — Reddit (6.6%), content less than 30 days old.

Only 11% of domains are cited by both ChatGPT and Perplexity. Appearing in an AI Overview gives a +35% click boost. Traffic from Perplexity converts 11 times higher.

🌍 AI search is not a single channel, but three different systems. There is no universal SEO strategy.

👤 Content may not appear in AI search not because of quality, but because of platform mismatch. FAQ-style content increases ChatGPT citability by ~40%.
