Each core research job below links the tool that does it here, for amazon.com. Research tools give a free preview without an account.
Paste a product link or ASIN. You see the search terms where it is one of the 3 most clicked products, its click and order share, and where it ranks right now.
Search volume, growth, click share and estimated orders for every search term in a niche, and where the niche is heading.
Up to 50 niches sorted by growth, searches or units sold. Then an 8-part report with an AI verdict to go, test or avoid.
Grade a title and bullets against Amazon's rules, with an AI rewrite on a free account. Then fill the backend search terms.
What buyers praise and complain about in a niche, and the search terms that waste ad spend. There is no ad management here.
Size tier, FBA and referral fees, ads and product cost, for profit, margin and ROI per unit. It works out costs before you sell. It does not read your sales.
