What our clients say
Amazon keyword research, done right
From backend keyword strategy to search term volume analysis to competitor gap discovery, Epinium gives you everything you need to build the most complete, highest-ranking listings on Amazon.
Research keywords. Fill every field. Rank.
Epinium connects to Amazon's data layer, analyses buyer search behaviour, benchmarks your listings against top competitors, and tells you exactly which keywords to place in each listing field for maximum organic visibility.
Find the best keywords from real Amazon data
- Amazon-native keyword dataGet search volume, click share, and conversion rate data sourced directly from Amazon — not extrapolated from Google — for a true picture of what buyers in your category actually search.
- Competitor keyword extractionAnalyse your top-ranking competitors' listings and extract the keywords they use in titles, bullets, and backend fields — then identify the gaps your listings need to fill.
- Seasonal keyword trendsIdentify how keyword search volumes shift by season, promotion period, and market event — so you can front-load the right terms before peak traffic windows open.
Build the perfect backend keyword strategy
- Backend field optimisationEpinium tells you exactly which keywords to use in your 249-byte backend field — deduplicated from your title and bullets — so you never waste a character or miss a high-volume term.
- Keyword cannibalisation preventionIdentify when multiple ASINs in your catalogue are competing for the same keywords — then restructure your strategy to distribute terms and protect each listing's ranking potential.
- Priority keyword mappingMap your top-volume keywords to the right listing fields — title gets the highest-priority terms, bullets get secondary terms, and backend captures everything that doesn't fit naturally.
Track what your keywords are actually doing
- Indexing status verificationConfirm Amazon is actually indexing your backend keywords — not just that you've added them. Detect indexing failures before they silently cost you organic visibility.
- Ranking progress over timeTrack keyword-by-keyword ranking movement after each listing update, so you can validate your keyword choices and iterate your strategy based on what the algorithm rewards.
- Impression and click data per keywordSee which keywords generate impressions and clicks for your listings — and which are taking up space in your backend without generating any real search visibility.

ExploreFrequently asked questions
What makes Amazon backend keywords different from regular keywords?
Backend keywords are hidden fields in Seller Central that Amazon indexes for organic search but doesn't display to customers. They're your chance to include additional high-volume search terms — synonyms, alternate spellings, related queries — without cluttering your visible listing content.
How does Epinium find the best Amazon backend keywords for my products?
Epinium combines real Amazon search volume data, competitor listing analysis, and AI-powered semantic expansion to identify the highest-relevance, highest-volume keywords your backend fields should contain. It also checks for duplicates with your title and bullets so you don't waste space.
Can Epinium detect if Amazon is not indexing my backend keywords?
Yes. Epinium monitors keyword indexing status and alerts you when a keyword that should be indexed is not appearing in search results. This lets you quickly identify and fix backend keyword issues before they silently drain your organic visibility.
Does Epinium work for keyword research across multiple Amazon marketplaces?
Yes. Keyword research and backend keyword recommendations are localised per marketplace. The search terms that convert on Amazon.de are different from Amazon.es or Amazon.co.uk — and Epinium gives you market-specific keyword data for each.
How many keywords can I research and track with Epinium?
Epinium supports tracking of hundreds of keywords per ASIN across all your connected marketplaces. There's no artificial cap on the number of keywords you can monitor — your tracking limit scales with your subscription plan.
