Use the engine tabs below to compare how ChatGPT, Gemini, Grok, and DeepSeek rank entities differently. Overall ranking summarizes the latest visibility signals across all tracked engines, while engine-specific tabs reveal whether a brand is broadly recommended or over-dependent on one answer system.

This ChatGPT page is a public AI rank tracking benchmark for Second-hand Marketplaces: it shows how entities rank inside one answer engine, using mention rate, recommendation strength, and latest snapshot signals. For model-level ChatGPT rank tracking across industries, use the ChatGPT benchmark hub. Use the private AI rank tracker when you need recurring monitoring for your own prompts, competitors, and saved answer history.

Why This Matters

Use the overall ranking to see which brands lead this industry at a glance, then drill into individual AI engines to understand where visibility is strong, weak, or inconsistent. The useful signal is not only the rank: mention rate, score gaps, latest refresh date, and engine outliers show whether the leader is durable or only winning in a narrow set of prompts.

Current Ranking Takeaways

eBay is currently #1 in the Second-hand Marketplaces ChatGPT public rank tracking benchmark, with a 74.4 AI Index and 85.7% mention rate.

Vinted is the nearest visible challenger on ChatGPT, trailing eBay by 7.4 points. That gap helps separate engine-specific visibility from broader cross-engine strength.

The ChatGPT benchmark refreshed on Jun 26, 2026, so it should be read as a public engine snapshot rather than a private recurring tracker run.
