Frequently asked questions
How accurate are the sales estimates?
Estimates are generated from historical price, stock and review movement for each product. They are a strong directional signal for comparing products and spotting demand — always pair them with the price history chart before committing to inventory.
How is Marter different from Keepa?
Keepa is built for Amazon. Marter is built specifically for Walmart Marketplace: Walmart price history, Walmart seller data, and a Chrome extension that works directly on Walmart product pages. See our full comparison at getmarter.com/compare.
