The button passes through /go/ebay-product-research so a click can be counted, then sends you to the source. No affiliate code is added.

What it does

Product Research is eBay's own sold-data tool, the one sellers still call Terapeak. eBay's Seller Center page says it is free for all sellers and lives under Research in Seller Hub. You can search keywords and products and see sales trends. Sourcing Insights, the category-demand tool next to it, requires a Basic Store or above.

Price

Product Research is free with Seller Hub. Sourcing Insights is included only with a Basic Store or higher, so that half is not free.

Marketplaces

eBay

Pros

Official eBay sold data, in the same account you already sell from.
No third-party subscription for the product search.

Cons

Sourcing Insights is gated behind a Store subscription.
It is eBay data only. It will not price a Poshmark or Mercari comp.
