If you’ve been trying to build consistent brand visibility inside ChatGPT, Semrush has a sobering data point for you: only 15.2% of topic categories have a clear brand leader across a series of related buyer questions.
That means in roughly 85% of categories, no single brand reliably wins ChatGPT’s responses. AI visibility is highly competitive, and it doesn’t hold even for established companies.
What Semrush Measured
Semrush compared category ownership in ChatGPT against conventional SEO metrics, including branded search volume, organic traffic, and Authority Score. The finding suggests that traditional SEO strength does not automatically translate into AI answer dominance.
The Operator Takeaway
For solopreneurs and small operators investing in generative engine optimization (GEO), this cuts both ways. The bad news: even strong brands can’t lock in ChatGPT mindshare. The good news: the field is genuinely open. Topical authority and consistent coverage of buyer questions appear to be the levers that matter, not domain authority or ad spend.
If AI search is part of your acquisition strategy, treating visibility as something you earn question by question is probably the right mental model right now.
