AI Search Market Share: Tracking Category Dominance
Measure your brand's relative influence in AI-driven category research.
Key takeaways
- AI search market share is your brand's relative influence in AI-driven category research: we track your slice of category recommendations versus competitors with Share of Recommendation, prompt-level share, and trend analysis so you can prove category dominance to leadership.
- The metric answers how much of the "shelf space" in high-intent AI answers you own compared to rivals, and whether that share is growing or shrinking over time across ChatGPT, Claude, Gemini, Perplexity, and Grok.
- Use market share data to prioritize content and campaign investments where you are under-indexed and to demonstrate ROI when your share increases after optimization or new content launches.
Knowing your AI search market share tells you how much of the category pie you own when users ask AI assistants for recommendations—and whether that slice is growing or shrinking. Brand Armor AI tracks this so you can prove category dominance and allocate strategy where it matters most.
The New "Share of Voice"
In the AI era, market share is measured by your "Share of Recommendation." If 70% of AI answers recommend your competitor, they own the market—regardless of your traditional SEO ranking.
Measuring Dominance
