Keyword Research for Marketplace Sellers: Amazon, Etsy, and eBay

Keywords Are Different on Marketplaces

Marketplace keyword research is fundamentally different from website SEO. On Google, you're trying to rank blog articles. On Amazon, Etsy, and eBay, you're trying to get your product in front of someone ready to buy NOW. The search intent is transactional, and the keyword strategy needs to reflect that.

Amazon Keyword Research

Tools: Helium 10, Jungle Scout, or the free Amazon search bar autocomplete

Strategy:

• Start with your main product term and look at Amazon's autocomplete suggestions — these are real searches
• Check competitors' listings — what keywords appear in their titles and bullet points?
• Use Brand Analytics (if enrolled in Brand Registry) for actual search volume data
• Focus on buyer intent keywords: "bamboo chopping board large" converts better than "chopping board"
• Include keywords in title, bullet points, description, and backend search terms

Etsy Keyword Research

Tools: eRank, Marmalead, or Etsy search autocomplete

Strategy:

• Etsy gives you 13 tags per listing — use all 13, every time
• Use long-tail phrases as tags, not single words. "Personalised birthday card" not "birthday"
• Etsy's algorithm weighs the first few words of your title most heavily
• Check the "Searches" section in Etsy Stats to see what people actually search to find your listings
• Seasonal keywords matter enormously on Etsy — add seasonal tags 6-8 weeks before the event

eBay Keyword Research

Tools: Terapeak (included with eBay store), eBay search autocomplete

Strategy:

• eBay's search is more literal than Amazon's — include exact product specifications in titles
• Use Item Specifics fields fully — eBay uses these for filtering and search
• Include brand, model number, size, colour, material, and condition in the title
• eBay titles allow 80 characters — use them all with relevant terms
• Terapeak shows what's actually selling, not just what's listed. This is crucial for understanding real demand

Common Mistakes

• Keyword stuffing — cramming irrelevant keywords makes your listing look spammy and can hurt ranking
• Ignoring long-tail — "leather wallet" has massive competition. "Slim RFID blocking leather wallet men" has less competition and higher buyer intent
• Not updating seasonally — add gift-related keywords before Christmas, remove them after
• Copying competitor keywords blindly — just because a competitor uses a keyword doesn't mean it works for them

The Practical Approach

Spend 30 minutes on keyword research per product. Use the platform's own search suggestions as your primary source — they're based on real buyer searches. Supplement with one keyword tool. Then test: run ads on your keywords and let the data tell you which ones actually convert. The search term reports from your PPC campaigns are the best keyword research tool there is.
