Can I research my competitor by eBay id?

Yes, you can research your competitor by eBay seller id, but we only show a portion of their listings and their recent sales. We understand the importance of benchmarking yourself against your competitors so we present up to their top 500 listings and the 30-day sales data for their top 100 listings.

When searching for a specific seller, use their eBay Seller ID, not their store name. Be sure the country selected is a market that the seller is active in otherwise it will return zero listings.
