Keyword strategy, powered by AI
Epinium analyses your product catalogue and search demand to identify the optimal keyword groupings for maximum organic and paid coverage.
From raw keywords to structured strategy
Epinium processes your keyword data with AI, groups semantically related terms, scores them by opportunity, and maps them to your catalogue — ready to act on.
Find every keyword your products should own
- Catalogue-wide keyword discoveryEpinium identifies all relevant keywords for every product in your catalogue — pulling from search data across your marketplaces.

Focus on clusters with the highest impact

ExploreFrequently asked questions
How does Keyword Clustering differ from a standard keyword tool?
Standard tools list keywords individually. Epinium groups them by semantic intent and maps them to your specific catalogue — telling you not just what keywords exist, but which ASIN should target which cluster.
Can I use the clusters for both SEO and PPC?
Yes. Clusters are designed to work for both listing content optimisation and search campaign structure — one keyword strategy covering organic and paid.
Does it work for multiple languages and marketplaces?
Yes. Epinium generates market-specific clusters for each marketplace you sell on — accounting for local search behaviour and language.
Where does the keyword data come from?
Search demand on Amazon comes from Epinium's deep integration with Seller Central, Vendor Central and Amazon Ads. For other channels, your assistant brings search-term reports through its connectors or your exports, and the CMO AI playbooks cluster them the same way. Selling on Amazon?
