FAQ
Frequently asked questions
How do I estimate sales of an Amazon product?
Find the product's Best Sellers Rank under Product details on its Amazon page. Enter that rank, its category and the marketplace above, and the estimator turns the rank into units sold per day. For monthly sales, revenue and history, open the product in a free SellerApp dashboard.
Can I see a competitor's sales by ASIN?
This page works from the rank. To check by ASIN, add the free SellerApp Chrome Extension: it shows estimated units and revenue on any Amazon product page you open.
How accurate are Amazon sales estimators?
They are estimates, not counts. Ours is tested at [±X%] for ranks under [Y]. Accuracy drops for new listings, seasonal spikes and variations that share one rank.
What is a good BSR on Amazon?
It depends on the category and marketplace. Compare a product's rank with others in the same category, and use the estimate to see what that rank means in units. The Category Benchmarks sheet lists units at common ranks for 100 categories.
How much should I spend on Amazon ads to launch a product?
Work back from demand: choose the share of a competitor's sales you want, then multiply the orders you need by your expected cost per order. The free Ad Budget Planner does this math by campaign type.
Which categories and marketplaces does it cover?
All 28 main Amazon categories, from Appliances to Video Games, on the US, UK, India and other Amazon marketplaces. Pick the category shown next to the rank on the product page.
