Abstract review keyword research clusters flowing into an analysis lens

Find the words buyers repeat and the products behind them.

Use keyword searches to surface market-wide patterns in buyer language. Use product searches to focus the same review intelligence on a specific ASIN list, catalog, or competitor set.

01

Keyword searches uncover demand, frustration, and buyer intent.

Create a search for defects, use cases, gift intent, materials, fit, durability, packaging, or any phrase buyers keep repeating.

  • See recurring complaints and positive phrases across many products.
  • Use real buyer wording for listing copy, PPC angles, and product positioning.
  • Filter matching reviews by marketplace, star rating, and when AMZShark found them.

02

Product searches keep research tied to the exact products that matter.

Paste ASINs, pull Amazon search results, or search products already known to AMZShark when you need a reusable product set.

  • Monitor review language for competitors, niche leaders, or your own catalog.
  • Compare product-specific complaints without losing ASIN-level context.
  • Export fresh review rows for the exact products your team is studying.
03

Move between broad discovery and focused product analysis.

Start with a keyword to spot market signals, then narrow into product searches once the relevant products, complaints, and buyer phrases are clear.

  • Go from market discovery to ASIN-level analysis without starting over.
  • Keep filters and exports consistent across keyword and product workflows.
