What Epinium covers

Every tool you need tosell on Amazon — connected.

Stop context-switching between tools that do not talk to each other. Epinium connects listing quality, advertising performance, keyword research, inventory management, and analytics into a single AI-powered workflow.

Listing Optimisation

AI rewrites titles, bullets, and backend keywords. Monitors keyword indexing and alerts you to content issues — so your listings always rank and convert.

PPC Automation

Set your ACOS target and the AI manages bids, harvests keywords, builds negatives, and creates campaign structure automatically — 24/7, no manual rules.

Sales & Ads Analytics

Unified P&L per ASIN: revenue, ad cost, estimated margin, and units — all in one dashboard. No more switching between Seller Central tabs and spreadsheets.

Keyword Research

Find high-volume, low-competition keywords for each marketplace. See search trends, competitor keyword gaps, and indexing opportunities in one tool.

AI Content Generation

Generate A+ content, brand story modules, and product descriptions in any Amazon marketplace language — from a single prompt, in minutes, not hours.

Multi-Marketplace Management

Platform capabilities

One platform that doeswhat five tools used to.

Listings

AI-optimised listings that rank and convert

Frequently asked questions

What Amazon seller tools does Epinium replace?

Epinium replaces separate tools for listing optimisation (like listing writers and keyword research tools), PPC management (like bid management software), analytics dashboards, inventory forecasting tools, and A+ content generators. Most sellers consolidate 4–6 subscriptions into one Epinium account.

Is Epinium suitable for new Amazon sellers?

Yes. Epinium guides you through listing creation, first campaign setup, and ACOS target configuration. The AI handles complexity so you can focus on your product catalogue — not on learning 5 different tools.

Which Amazon marketplaces does Epinium support?

Epinium supports all major Amazon marketplaces including EU (Spain, Italy, Germany, France, UK), US, and more. You can manage your entire international Amazon presence — listings, campaigns, and analytics — from one platform.

How does Epinium connect listing quality and advertising performance?

Epinium is the only platform that uses the same keyword data for both listing optimisation and PPC campaign management. Keywords discovered through listing analysis are automatically added to campaigns, and high-converting ad search terms are fed back into listing content — creating a compounding improvement loop.

Can I use only some of Epinium's tools, or do I have to use all of them?

You can activate only the modules you need — listing optimisation, advertising automation, or analytics — and expand as your business grows. There is no requirement to use every feature from day one.
