AI Models vs Marketplace Agents
AI Models
Marketplace Agents
AI models and marketplace agents often recommend different brands. Marketplace results tend to favor best-sellers and price-competitive options, while AI models prioritize editorial authority and product depth.
How we measure this
Each benchmark runs the same standardized prompts across multiple leading AI systems, including ChatGPT, Claude, Gemini, and Perplexity. We use consistent, category-specific questions designed to surface genuine product recommendations — not sponsored results.
Responses are parsed to extract brand mentions, rank position, and frequency. We then analyze cross-model agreement, identify which brands consistently appear in top positions, and flag where AI outputs diverge from marketplace trends.
Evergreen categories are benchmarked monthly. Results reflect organic AI behavior at the time of testing. Read the full methodology
