A full keyword list is built in stages rather than pulled from a single tool run:
The verified output then gets segmented into the Helium 10 Four-List Keyword System (Main, Related, Misspelled, Master) for independent targeting and testing.
After the Main list is built from the reverse-ASIN ('steal') pull, take its single top-volume keyword and search it directly in Cerebro (not via reverse ASIN), apply the Organic filter, and merge the results back into the existing lists — Helium 10 auto-dedupes on import, so this only adds keywords the ASIN-based pull missed rather than creating duplicates.
Competitor sourcing: identify the top 3 related/competitor listings via a 'Top Related Products' tab, then run each through Sellerize Keyword Re-ranker to pull every keyword that listing ranks for. Merge the resulting competitor spreadsheets, deduplicate (e.g. Numbers' 'is distinct' filter), and re-apply the High-Conversion Keyword Selection Strategy and Relevance-Sort Keyword Cleanup filters before combining with your own list.
Manual verification: as a final QA pass, manually search every candidate keyword on Amazon (All Departments). Keywords whose results don't match the product are highlighted rather than deleted, and reserved for listing-indexing use only (backend search terms) — see Amazon Generic Keywords (Backend Search Terms Field). Unhighlighted keywords are PPC-ready; highlighted ones are indexing-only.
