Perplexity is an answer engine built around real-time retrieval: it actively recrawls its sources with PerplexityBot and cites the ones it uses to compose an answer. This tag gathers what we measure about the engine — its real share of AI referral traffic next to ChatGPT, its strong preference for recent content, and what it takes to end up among the sources it cites.

A study of 22.7 million citations finds ChatGPT and Perplexity share only 11% of their sources. What that means for your GEO strategy.

6.77M visits analyzed over 19 months. ChatGPT drives 92.4% of AI traffic, Claude is up 64x, Copilot down 96%. Where to focus your GEO efforts in 2026.
