Why UK Brands Choose Sellonics Over Other Amazon Agencies
Most Amazon agencies UK sellers have worked with before make large promises at the pitch stage and deliver inconsistent results after onboarding. Here is a direct comparison of how those agencies operate versus how we work.
How Other Amazon Agencies Operate
- Test and see what happens with your budget
- Hand your account to a junior with limited experience
- Send reports designed to obscure poor performance
- Onboard any brand regardless of whether they can help
- Charge a monthly fee regardless of revenue results
How Sellonics Operates
- Run the numbers and model the opportunity before spending
- Assign senior strategists who have scaled Amazon brands
- Report through clear dashboards that show what is working
- Turn down brands where we are not confident we can deliver
- Structure payment around revenue growth, not retainer fees
Why Sellonics Is The Right Amazon Agency UK Brands Should Consider
We do not run experiments on client budgets. Every account is managed by senior strategists using proprietary playbooks developed across hundreds of Amazon brands. Our 93% client retention rate is the clearest indicator of how we perform, and it consistently outperforms the industry average.
If you are comparing Amazon agencies UK-wide, retention is the metric that matters most. It reflects whether clients stay because results compound over time, not because they are locked into a contract.

Frequently Asked Questions
How quickly can I expect results?
Accounts see measurable improvements in wasted ad spend and ACoS within the first 30 days. Meaningful revenue growth typically builds over 60 to 90 days as PPC, SEO and listing changes begin compounding together.
I have used other Amazon agencies before. What makes Sellonics different?
Amazon agencies UK sellers have worked with previously hand accounts to junior staff, send reports that are difficult to interpret, and onboard any brand that can pay the retainer. We only take on brands we are confident we can help, assign a senior brand manager to every account, and report in plain numbers with no jargon.
What if my Amazon account is already performing well?
We start with an honest audit rather than a sales pitch. If your account is performing well, we will tell you directly. We only recommend changes where there is a genuine and quantifiable opportunity to improve.
Do you work with new Amazon brands?
Yes, alongside established sellers. Whether you are launching your first product or scaling an account already generating seven figures, we build a strategy around your current position and realistic growth targets, not a generic playbook.
Is there a long-term contract commitment?
No fixed long-term lock-in is required to get started. We prefer to earn a long-term relationship through consistent results rather than hold clients to a contract. Our 93% retention rate reflects that approach.
Does account management include creative and listing optimisation?
Yes. Design, A+ content and listing optimisation are included as part of full Amazon account management. They are not a separate add-on negotiated later.
Which Amazon product categories do you work in?
We work across a wide range of categories including home and kitchen, supplements, pet care and office equipment. The most important factors are proven product demand and genuine room for growth, not the specific category.
Can you manage accounts across multiple Amazon marketplaces?
Yes. We manage accounts across the UK, US, EU and other Amazon marketplaces. Each region gets a separate strategy based on local competition and how buyers search and purchase in that market.
Do you offer TikTok Shop management alongside Amazon?
Yes. For brands with an established Amazon presence, we also set up and manage TikTok Shop as a complementary sales channel, using the same product data and creative assets that are already performing on Amazon.
