Amazon Keyword Research: Complete Guide for Sellers
How to find, evaluate, and use keywords for Amazon listings — from title keywords to backend search terms.
Keyword research for Amazon is different from SEO for Google. Amazon's search intent is almost always commercial — buyers are looking for a specific product, not information. This means keyword research is about finding the exact terms buyers use when they are ready to purchase.
Finding keywords: start with Amazon autocomplete. Type your primary product type into the search bar and record every autocomplete suggestion. These are the highest-volume terms for your category. Then search each suggestion and record its autocomplete suggestions. This builds a keyword tree that covers your category.
Second-tier research: use a keyword research tool (Helium 10 Cerebro, Jungle Scout Keyword Scout, or similar) to find terms your competitors rank for that you do not currently target. Enter your top competitor's ASIN into the reverse ASIN lookup and export their top 50 keywords.
Evaluating keywords: prioritize keywords by: search volume (how many buyers search for this), relevance (how well it describes your specific product), and competition (how hard it is to rank — products with 5,000+ reviews rank for the most competitive terms, newer listings need to find lower-competition terms).
Placing keywords: your title should contain your primary keyword (highest search volume, most relevant) within the first 80 characters. Your secondary keywords should appear in bullet points naturally. Tertiary keywords and synonyms go in backend search terms. Do not repeat keywords across all three placements — each location is for different keywords.
Backend keywords best practices: 250 bytes maximum, separated by spaces (no commas), no repeated terms, no competitor brand names, focus on synonyms and alternate spellings not in your visible content. The backend keyword field is the most commonly under-optimized part of Amazon listings.
Monitoring keyword performance: the Search Term Report in Campaign Manager shows which keywords led to purchases in your PPC campaigns. High-converting PPC keywords should be in your backend keywords and considered for title/bullet inclusion.
