About this extension

Seller Toolkit is an Amazon product research and competitor analysis extension for sellers, FBA researchers, and anyone evaluating products and market opportunities. Research listings as you browse, save evidence, compare changes over time, and track competing products.

PRODUCT AND COMPETITOR RESEARCH

Get useful product data directly in Amazon search results and product pages, including:

Best Sellers Rank (BSR) and category rank
Prices, ratings, and review counts
Sponsored listing status
Estimated sales and revenue
Competitor listing details and ASINs
Market Pressure and Niche Snapshot

Use search results to explore a market and product pages to examine individual competitors in more detail.

RESEARCH, SAVE, COMPARE, TRACK

Seller Toolkit turns browsing into a repeatable research workflow.

Research: Examine products, listings, keywords, and competition.
Save evidence: Capture product and market details for later reference.
Compare: Review saved snapshots to see how prices, listings, and other data change.
Track: Follow product ASINs and build a history of listing changes over time.

Your saved research helps you revisit earlier findings instead of relying on memory or scattered notes.
