A 2026 study by geoSurge tested ChatGPT, Gemini, Perplexity, and Google AI Overviews across thousands of brand-recommendation queries and found a pronounced concentration in which brands get recommended.
The Key Finding
In 63% of category-specific queries, AI systems draw recommendations from the same pool of 5-6 brands per category.
Established brands appear in AI answers 3.2 times more often than less-known alternatives — regardless of product quality.
Why This Happens
AI systems generate recommendations from patterns in training data. Brands that appear frequently across authoritative sources — publications, comparison sites, review platforms, news — get recommended more often.
Self-published content on your own domain has minimal impact on AI recommendation frequency. The gap is in external representation, not content volume.
The Feedback Loop
More AI recommendations → more brand mentions across the web → more representation in AI training data → even more recommendations.
Brands already in the top-cited group compound their advantage. Brands outside the group need active external presence-building to break in.
What Actually Builds AI Visibility
- Features in authoritative media (one Forbes/Inc feature > hundreds of blog posts)
- Complete, actively maintained profiles on G2, Capterra, Crunchbase
- Original proprietary research that other publications cite
- Consistent presence across structured review platforms
