Reasons Amazon Accounts Lose Money

Broken variations, duplicate listings and suppressed ASINs block sales you’ve already paid to attract. Ad campaigns without a clear structure push ACoS up while revenue stays flat. Thin keywords and generic images send shoppers to a competitor’s page. Slow fixes with Seller Support leave your products offline for hours or days.

Why Brands Choose Sellonics

We know UK and EU buyers. Each market searches and buys differently. So we plan your growth around local keywords, pricing and delivery expectations.

Frequently Asked Questions

Most accounts see a drop in wasted ad spend and a lower ACoS (advertising cost of sales) within the first 30 days. Meaningful revenue growth usually builds over 60 to 90 days, as ads, SEO and listing changes start working together. Timelines vary by category and starting point, so we’ll give you a realistic estimate after your audit.

We don’t believe in charging a flat monthly fee no matter what happens to your sales. Our fees are tied to the growth we deliver, so we only do well when your account does. The exact structure depends on your account size and goals, and we’ll walk you through it on your free consultation call, with no surprises later.

We work best with brands that have proven product demand and real room to grow, whether you’re launching your first product or running a seven-figure account. We turn down brands where we aren’t confident we can deliver. If we’re not the right fit, we’ll say so on the first call.

Many UK sellers tell us their previous agency passed the account to a junior, sent reports that were hard to follow, or took on any brand that could pay. We assign a senior strategist to every account, report in plain numbers, and only take on brands we believe we can help.

We start with an honest audit, not a sales pitch. If your account is performing well, we’ll tell you directly. We only recommend changes where there’s a genuine, measurable opportunity.

Yes. Your Seller Central or Vendor Central account, listings, brand assets and ad data always remain yours. We work through your account with the access you grant, and you can review or change that access at any time.

You’ll have access to clear dashboards showing what’s working and what isn’t, plus regular check-ins with your senior strategist. No chasing for updates and no jargon.

Yes. We manage accounts across the UK and other Amazon marketplaces, and each region gets its own strategy based on local competition and how buyers search and buy there.
