What it means

What this means for your brand

  • The audience is already there

    OpenAI reports 1 billion weekly users, and Pew Research Center finds 44% of US adults use ChatGPT. Being absent from its answers means missing a mainstream channel.

  • Google rank does not decide citations

    Semrush found about 90% of ChatGPT-cited pages rank in position 21+. LLMReach found only 10.7% of cited sites sit in Google's top 10.

  • Many brands compete in each answer

    LLMReach's measurement shows ChatGPT names 6.4 brands per buyer answer and cites 4.2 sites. Winning a mention means being one of a few cited sources.
