How to research Amazon products to sell from Chrome
Joseph HuLast reviewed September 14, 2026
Quick answer
Start free with AMZBase and Keepa for rank, price history and the basics. When you need sales estimates and keyword data across a whole search page, Helium 10.
Amazon shows a product's Best Sellers Rank and little else. Seller extensions turn that rank into a sales estimate, add price and rank history, count the competing sellers and calculate the fees, on the page you are already looking at. The five below are listed as of September 2026; two are the paid suites most sellers know, and three are free enough to start with.
Read Amazon's own signals before paying for estimates
Amazon publishes enough to rule a product in or out: the Best Sellers Rank, the number of sellers, the review count and dates, and its own fee calculator. It takes a few minutes per product and costs nothing.
- 1On the product page, find Best Sellers Rank under Product information and note the rank in its main category; lower is more sales.
- 2Open the "New & Used" or "Other sellers" panel and count the sellers; a crowded listing means a price war.
- 3Count reviews from the last 30 days by sorting reviews by Most recent; steady recent reviews mean steady sales.
- 4Paste the ASIN into Amazon's Revenue Calculator in Seller Central to see the FBA fees at your intended price.
- 5Type the product's main keyword into the Amazon search box and note the autocomplete suggestions; they are real searches.
That gives you a rank, not a sales number, one product at a time. An extension estimates monthly sales for every listing on a search page, charts the history and does the fee arithmetic in place.
Start free, with no account
Two listed extensions give you the core research data without a subscription: one overlays rank, offers and listing data on search and product pages, the other charts price and rank history.
