Questions

What is eBay sell-through rate?
Sell-through rate compares sold listings to active listings for a product or keyword over a defined window. A higher rate usually signals stronger demand or lower competition.
How do I calculate eBay sell-through rate?
Divide sold listings by active listings, then multiply by 100. For example, 40 sold listings and 200 active listings equals a 20% sell-through rate.
Should I use sold listings or completed listings?
Sold listings are stronger for demand research because they show items buyers actually purchased. Completed unsold listings can still help you understand overpricing and stale competition.
How does Resellbot help after I calculate sell-through?
Use Resellbot eBay sold listings to validate exact comps, then use the fee calculator to check whether the demand still leaves enough margin.
