The AI Search Divide: Top Brands See 73% Visibility — Niche Players Are Invisible at 11%
New benchmark shows brand visibility in AI search drops 30 points per maturity tier
Generative Engine Optimization (GEO) is emerging as the new SEO. A preprint from Pratyush Kumar at Ranqo examines how brands are cited and recommended by AI search engines like ChatGPT, Claude, Perplexity, and Gemini. The study analyzes over 100,000 prompt responses across 100+ brands tracked between March and May 2026. It reveals a stark three-tier visibility ladder: global household names (Stripe, Nike) appear in 73% of relevant AI answers, established mid-market brands (Olipop, Klaviyo) in 44%, and niche/small brands in just 11% – roughly a 30 percentage point drop per tier. This suggests AI engines heavily favor already-authoritative brands, making it harder for SMEs, DTC brands, and creators to gain visibility.
When AI engines cite sources, 78% link to corporate websites. Among non-corporate sources, YouTube leads, followed by Reddit, editorial media, and Wikipedia. The most-cited content format is the ranked 'best-of' listicle, accounting for 21% of all citations. A striking finding: sentiment toward brands is highly unstable, flipping positive/negative 6.7 times more often than the brand is mentioned at all, indicating AI answers can vary dramatically in tone. The paper closes with seven proposed v1.1 protocols to test causal improvements to AI visibility. For marketers, this provides the first large-scale baseline to measure and optimize brand presence across generative engines – a critical new battleground for digital visibility.
- Brand visibility in AI search follows a three-tier ladder: 73% for global brands, 44% for mid-market, and 11% for niche brands – a 30-point drop per tier.
- 78% of AI citations go to corporate websites; 'best-of' listicles are the top content format at 21% of all citations.
- Sentiment toward brands fluctuates 6.7x more often than brand mentions, making tone highly unstable across AI responses.
Why It Matters
Brands must now optimize for AI search visibility as traditional SEO fades, with a clear data-driven baseline to guide strategy.
