How to gather your keyword files

Use these three Helium 10 exports, then manually remove irrelevant phrases before upload

  1. Main keyword (Magnet) — Run your main keyword in Helium 10 Magnet and export the supporting keyword CSV/XLSX.
  2. Top ASINs (Reverse ASIN) — Use Helium 10 Xray to find strong ASINs for that same main keyword, then run those ASINs in Cerebro Reverse ASIN and export the highest-performing keywords.
  3. Competitor keywords (optional) — Pick one competitor from Xray that you plan to compete with, run that ASIN in Cerebro, and export its keywords.
  4. Manual cleanup, then upload — Review each export and remove phrases unrelated to what you sell. Upload the cleaned files here; PrepMonster removes exact duplicates and returns a clean set for listing and keyword work.

For demand, YoY trend, and seasonality on a single keyword, use the Search Volume Analyzer with a Helium 10 chart export.
