“Agencies just spend your money.” “Ads are the only thing that matters.” “If I hire help, I lose control.”
You may have heard some of these claims from other sellers, in forums or even from your own team. Some have a grain of truth, but most are outdated or only partly correct.
If you’re thinking about hiring an Amazon advertising agency, it helps to separate the myths from the facts first. Here are six of the most common misconceptions and what UK Amazon sellers should know.
Myth 1: “Ads Alone Will Fix My Sales”
The truth: Ads bring visitors, but your listing has to turn them into buyers.
Picture a shop with a great sign outside and a messy, confusing shop floor. People come in, look around and leave. That’s what happens when ads send shoppers to a weak product page with poor photos, few reviews or a confusing title.
A good agency will often review your listing before spending your budget. Many Amazon advertising services include listing advice for this reason.
Professional Amazon product listing services can help improve product titles, descriptions and content so potential customers understand what they’re buying.
If an agency promises that ads alone will transform your results, ask how it will address the product page itself.
Myth 2: “A Low ACoS Always Means Success”
The truth: The right ACoS depends on your profit margin, not a magic number.
ACoS shows how much you spend on advertising compared with the sales attributed to those ads.
A very low figure sounds great, but it may mean your campaigns are too cautious and you’re missing valuable sales opportunities. A higher figure can be reasonable for products with healthy margins or during a launch.
The real question is whether you’re making a profit after accounting for product costs, Amazon fees, advertising and other expenses.
A good agency will ask about your margins before setting ACoS targets.
Myth 3: “Agencies Can Guarantee Results”
The truth: Nobody can guarantee sales on Amazon.
Competitors, prices, reviews, stock availability and seasonal demand all affect performance. Many of these factors are outside an agency’s control.
What an experienced agency can do is make informed decisions, test strategies carefully and respond when problems arise.
Be cautious of promises such as “double your sales in 30 days.”
A more realistic commitment includes a clear plan, transparent reporting and ongoing optimisation.
Effective Amazon ads management involves consistent work, not shortcuts.
Myth 4: “If I Hire an Agency, I Lose Control”
The truth: You can retain control when the partnership is structured properly.
Your Amazon seller account should remain under your business’s control. Agencies can be granted appropriate permissions to manage advertising and related tasks.
You should also have access to campaign performance information and understand how your advertising budget is being used.
A good partnership works like this: you establish business goals and spending limits, the agency handles agreed day-to-day activities, and both parties review performance regularly.
Before signing, confirm who controls account access, who can adjust budgets and what happens when the agreement ends.
A fair contract should explain these responsibilities clearly.
Myth 5: “Agencies Are Only for Big Brands”
The truth: Small and medium-sized brands can also benefit from professional support.
Smaller businesses may not have the resources to hire separate advertising specialists, designers and content writers.
An agency can provide access to different skills without requiring multiple full-time employees.
However, professional management isn’t automatically worthwhile for every seller.
If your advertising budget is very limited, agency fees may outweigh the benefits. There may also be insufficient campaign data to support meaningful testing.
A responsible agency should explain whether ongoing management makes financial sense or whether a one-off audit would be a better starting point.

Myth 6: “Once the Campaigns Are Set Up, the Work Is Done”
The truth: Amazon advertising requires regular attention.
Customer search behaviour changes, competitors adjust their bids and seasonal demand affects purchasing decisions.
A campaign performing well in March may require adjustments by June.
Regular management includes:
- Reviewing search terms that generate sales and those that waste money.
- Adding negative keywords where appropriate.
- Adjusting bids and budgets based on performance.
- Testing relevant ad formats and targeting options.
- Monitoring inventory to avoid advertising unavailable products.
This is a major part of what you pay for when hiring an Amazon advertising agency: ongoing monitoring and informed optimisation.
So, What Should You Expect From a Good Agency?
Now that we’ve addressed the myths, here’s what a reliable agency relationship should include:
- A clear start: An audit of your account, listings and existing campaigns.
- A plan with goals: Advertising targets based on your margins and business objectives.
- Plain-English reports: Performance updates you can understand and use.
- Honest advice: Recommendations that explain when something isn’t worth the investment.
- Realistic expectations: Meaningful improvement often takes time rather than a few days.
A good agency should explain both its successes and the areas that still need work.
Questions to Ask Before You Decide
Before choosing an Amazon advertising agency, ask these five questions:
- How do you establish a target ACoS for each product?
- Who controls the advertising account and campaign data?
- How often will we speak, and who will manage my account?
- What happens if results aren’t improving after three months?
- What’s included in the management fee, and what costs extra?
The answers will help you understand how transparent, organised and realistic the agency is.

Final Thoughts
Many concerns about hiring an Amazon advertising agency come from misconceptions: that advertising fixes everything, low ACoS always means success, results can be guaranteed, agencies take away control, professional support is only for large brands, and campaign setup is the end of the work.
