The real search engine market share of ChatGPT

ChatGPT matters enormously as a decision surface — even when classic 'search share' charts understate it.

Oct 19 2025

Comparing ChatGPT to Google on click-share alone misses the point. Much of ChatGPT's influence never becomes a click. Treat it as a parallel discovery and decision channel with its own measurement.

How to think about share

  • Track branded and category prompt visibility, not only referrals
  • Survey customers for AI-assisted discovery
  • Compare model-level visibility, not a single blended score

Google's AI surfaces may win on raw reach; ChatGPT still shapes consideration for many B2B and consumer categories. Measure both in Anny.
