12. Scientific Seller

Scientific Seller is unique among the apps in this list for its slower, more deliberate search process. It can often run searches overnight or longer.

This can reveal related keywords that might otherwise never be discovered, improving the ability to match products to customers.

Scientific Seller analyzes Amazon buyer keywords and other sources (like LSI) to narrow down its data. The process takes longer because fewer searches find new relevant keywords the further they get from seed keywords. However, eventually, these searches often find many results that otherwise go undiscovered. Since Amazon specifically ranks products based only on selected keywords, customers only find products that match their search queries. Sometimes, customers use strange or just uncommon terms for products. Scientific Seller boosts your ability to find and match those keywords with yours.

  • Specific to Amazon customer searches
  • Can find keywords you may otherwise miss


  • Results can take a lot of extra time
