Amazon Keyword Research Guide 2026 (for rankings + compliance)
Start from customer language
Search your product the way a buyer would; note the exact phrases. Tools (Sonar, KeywordTool.io) expand this.
Prioritize intent, not just volume
A specific long-tail ('insulated water bottle 32oz') converts better than a broad 'bottle'.
Place, don't stuff
Title + bullets + backend. Repeating the same word looks spammy to Amazon.
Keep claims compliant
Even keyword-driven copy must avoid banned/unverifiable claims — pre-check the written listing.
