Amazon Ads Case Study: £6,320 Spend to £42,094 Sales (6.66x ROAS)
£6,320 spent on Amazon ads. £42,094 in tracked sales. 378 orders. One UK seller account.
In this Amazon Ads case study, learn how ROI Hunt, an Amazon marketing agency specialist, transformed the poor-performing Sponsored Ads campaign of a UK Home & Kitchen seller into a 6.66x ROAS growth machine without increasing the daily budget in 12 weeks.
The Objective
- Increasing ROAS in Amazon Sponsored Products and Sponsored Brands
- Eliminating waste from spending on non-converting targets
- Improving the effectiveness of Amazon Marketplace Advertising efforts in the UK storefront
- Building a scalable Amazon PPC management strategy in the UK market
- Increasing orders while not inflating cost per acquisition.
The challenges
- Prior to the optimisation process, the account exhibited all the common traits of an unmanaged Amazon Sponsored Ads account UK:
- A significant portion of the budget is allocated to targets that have no impressions
- Spending on targets that generate no sales
- Keywords and products that receive clicks but no orders
- Unclear distinction between harvesting campaigns (Sponsored Products) and discovery campaigns (Sponsored Brands)
- Unpredictable ROAS without any optimisation routine.
Left unchecked, this is exactly how Amazon ad accounts bleed budget visibility without profitability.
The Strategy: Execution Over Assumption
1. Individual Target-Level Optimisation of Amazon Ads
Each target had its own audit. Targets with spend and no sales were the first ones to be paused; targets with impressions and no clicks – to be changed or deleted.
There was no target left without proof.
2. Cleaning Up of Search Terms & Negative Targets
The weekly search terms report was used for adding high-intent keywords and blocking irrelevant keywords. It is a must for Amazon PPC Management UK.
Clicks that could potentially waste money were filtered out in advance.
3. Balancing Sponsored Products & Sponsored Brands Budgets
Conversion-oriented Sponsored Products were allocated budget along with discovery-oriented Sponsored Brands based on real order data.
Not every penny spent was just spending; every pound did its job.
4. Real ROAS-Based Bid Adjustments
Bid adjustments were done target-by-target using real ROAS and ACOS data and not relying on platform recommendations. This is how Amazon Ads Optimisation works.
There is no room for emotions here.
5. Gradual Scale-Up of Profitable Targets
After profitable targets, budgets were scaled up in small steps while keeping ROAS intact. Growth was built on experience.

Performance Snapshot
- Total Ad Spend: £6,320.14
- Tracked Sales: £42,094.18
- Orders: 378
- Average ROAS: 6.66x
Spend, sales, orders, and ROAS all trended upward consistently across the 12-week window, not a single spike, but a steady curve, the kind you want to see in any healthy Amazon Sponsored Ads UK account.
Key Takeaway
Amazon Performance Marketing does not incentivise advertisers based on ad budget spend. Structure is incentivised.
The typical UK seller tends to keep under-performing campaigns running due to their habits. The success of this particular account was achieved by ROI Hunt by cutting everything that does not work and investing in what does work every single week.
Conclusion
Profitably scaling an Amazon account is never achieved through an increased ad budget. Rather, it’s achieved through precise ad budget management.
As an Amazon advertising agency specialising in Amazon PPC management UK, we help you turn such campaigns into profit drivers.
