Most small business owners searching for amazon marketing services are not actually looking to advertise on Amazon. They are trying to understand whether Amazon's advertising ecosystem is relevant to them — and whether it makes more sense than doubling down on Google Ads.
This article explains what amazon marketing services actually covers, how it compares to Google Ads for SMEs, and why most small businesses end up getting better returns from search advertising they can actually control.
What Amazon Marketing Services Actually Means
Amazon Marketing Services is the former name for what Amazon now calls Amazon Ads — the suite of paid advertising products available to brands selling on the Amazon marketplace. The name stuck in common usage, so when people search for amazon marketing services, they are usually asking one of three things: what it is, whether it applies to their business, or how it stacks up against other paid channels.
The short answer is that amazon marketing services is primarily designed for brands that already sell physical products on Amazon. It includes Sponsored Products, Sponsored Brands, and Sponsored Display — all of which appear within the Amazon ecosystem and target shoppers who are already further down the purchase funnel than a typical Google search user.
For SMEs who do not sell on Amazon, the service is essentially irrelevant. For those who do, it can be a useful supplementary channel, but it comes with its own cost structure, steep learning curve, and performance opacity that makes it difficult to manage without dedicated resource.
Amazon Marketing Services vs Google Ads: A Direct Comparison
Understanding the difference between amazon marketing services and Google Ads is not just an academic exercise — it determines where you put your budget and what kind of return you can realistically expect.
Amazon Ads operate within a closed marketplace. Your ads appear to people who are actively shopping on Amazon, which sounds appealing, but it means you are paying for visibility within Amazon's walled garden rather than reaching people across the open web. Amazon takes a cut of sales, and your advertising data stays inside their system.
Google Ads, by contrast, reaches people at the moment they are searching — anywhere, for anything. A plumber, a solicitor, a local gym, a software consultancy: they can all run effective Google search campaigns without needing to sell through a third-party marketplace. The targeting is broader, the data is yours, and the return on ad spend is easier to attribute.
Here is a side-by-side comparison to make the trade-offs concrete:
| Factor | Amazon Marketing Services | Google Ads |
|---|---|---|
| Who it suits | Amazon sellers with product listings | Any business with a website |
| Ad formats | Sponsored Products, Brands, Display | Search, Display, Shopping, Video |
| Audience intent | High purchase intent (within Amazon) | Variable — from awareness to purchase |
| Data ownership | Limited — stays in Amazon's system | Full access via Google Ads and GA4 |
| Minimum commitment | No minimum, but competitive CPCs | No minimum, flexible daily budget |
| Management complexity | Moderate to high | Moderate to high |
| Best for SMEs | Product-based Amazon sellers | Most SMEs across all sectors |
For most SMEs reading this, Google Ads is the more applicable channel. That does not mean amazon marketing services is without merit — but it is a narrower tool for a narrower use case.
Why Google Ads Suits Most SMEs Better
Search intent works in your favour
Google processes billions of searches every day. When someone types in a service you offer, they are signalling active interest. That is fundamentally different from browsing a marketplace and being shown an ad for a competing product. For service businesses, local businesses, and B2B companies, Google search campaigns are almost always the right starting point. If you are still getting to grips with the basics, our guide on what paid search is and how it works for SMEs covers the fundamentals clearly.
Budget control is more transparent
With Google Ads, you set daily budgets, bid limits, and can see exactly where every pound is going. Amazon's auction system can be similarly granular, but the reporting is tightly controlled by Amazon and does not give you clean visibility into impression share or auction dynamics across the broader web.
Managing Google Ads effectively does require time and attention. Bids need adjusting, underperforming keywords need pausing, and budget needs moving toward what is actually converting. Many SMEs underestimate how much ongoing work that involves — which is precisely why AI-managed Google Ads has become a credible alternative to hiring an agency.
Shopping campaigns bridge the gap
If you are an ecommerce business that sells on both Amazon and your own site, Google Shopping campaigns give you a strong alternative to amazon marketing services for product-based advertising. Google Shopping Ads pull directly from your product feed and show visually rich ads in search results. For more on how that works, see our guide to Google Shopping Ads for SMEs.
The Real Cost of Managing Either Channel
What SMEs actually spend
One of the most common mistakes we saw during nine years running a marketing agency was SMEs dramatically underestimating the management overhead of paid advertising. The ad spend itself is only part of the cost. Someone has to monitor performance, adjust bids, write new ad copy, pause what is not working, and report back to the business owner.
For a detailed breakdown of what Google Ads actually costs to run — including management fees — the guide on PPC management fees for SMEs is worth reading before you commit to any channel.
The hidden cost of inattention
Leaving a Google Ads account unattended for weeks is one of the fastest ways to burn through budget with nothing to show for it. Automated bidding strategies can optimise for the wrong signals. Broad match keywords can start matching irrelevant queries. Campaigns that looked profitable in month one can deteriorate significantly by month three if nobody is watching.
This is not a problem unique to Google Ads — amazon marketing services has the same issue. Any paid channel requires active management. The question is whether you are paying a human to do it or finding a smarter way to get it done.
Overtime is an AI agent that logs into your Google Ads account directly, adjusts bids, pauses underperforming keywords, reallocates budget toward what is converting, and sends you a plain-English summary of what it did and why. It does the daily account management work that most SMEs cannot do consistently on their own.
When Amazon Marketing Services Is Worth Considering
This article would be one-sided without acknowledging where amazon marketing services genuinely earns its place. If you sell physical products on Amazon and have good reviews and competitive pricing, Sponsored Products can generate immediate visibility to high-intent shoppers. The return on ad spend in certain product categories is strong because the audience is already in buying mode.
The cases where it tends to underperform for SMEs are worth being honest about. If your margins are thin, Amazon's combination of referral fees and advertising costs can make profitability elusive. If you are a newer seller with limited reviews, your ads will convert at a lower rate and your cost-per-sale will be high. And if you are a service business of any kind, amazon marketing services simply does not apply to you.
For SMEs who do want to explore product advertising across both Google and Amazon, the guide on ecommerce ads management for SMEs is a useful place to start thinking about channel strategy.
The cleaner play for most SMEs in 2026 is to get Google Ads working well first, understand your cost per acquisition, and then consider Amazon as an additive channel if the product and margin profile makes sense. Trying to run both simultaneously without proper management on either tends to dilute results across the board. See our guide on how to fix high cost per acquisition in Google Ads if that is already a live problem in your account.
If you are weighing your options between using an agency, doing it yourself, or finding a middle path, the comparison of the best Google AdWords company options for SMEs is a useful reference before committing budget.
For most SMEs, the decision on amazon marketing services comes down to one question: are you selling on Amazon's marketplace? If yes, test it with a modest budget and track your advertising cost of sales carefully. If no, your time and budget is almost certainly better spent on Google search, where you own the customer relationship and have full visibility into the data.

FAQ
What is Amazon Marketing Services and who is it for?
Amazon Marketing Services is the former brand name for Amazon Ads — the advertising products available to sellers within the Amazon marketplace, including Sponsored Products and Sponsored Brands. It is designed for businesses that sell physical products on Amazon and is not applicable to service businesses or companies that sell exclusively through their own website.
How does Amazon Marketing Services compare to Google Ads for SMEs?
Amazon Ads reach shoppers within the Amazon marketplace, making them well suited to product-based sellers with strong reviews and healthy margins. Google Ads reaches people actively searching across the open web and suits a far wider range of SMEs, including service businesses, local companies, and B2B organisations. For most SMEs, Google Ads offers more flexibility and clearer data ownership.
Why should SMEs prioritise Google Ads over Amazon advertising?
Google Ads gives you direct access to search intent across your entire potential audience, not just Amazon shoppers. You own your customer data, you are not competing inside Amazon's ecosystem, and you can drive traffic directly to your own website where you control the customer journey and retain the full margin.
Can a small business run both Google Ads and Amazon Marketing Services at the same time?
Yes, but it requires proper management of both channels. Running both simultaneously without active oversight on either tends to produce mediocre results across the board. The more practical approach for most SMEs is to establish profitability on one channel first, then expand. Google Ads is typically the better starting point for businesses without an existing Amazon presence.
Do I need an agency to manage Google Ads effectively?
Not necessarily. An agency offers human expertise but comes with significant cost and minimum commitments. AI agents like Overtime manage the day-to-day optimisation work — bid adjustments, pausing underperformers, budget reallocation — at a fraction of the cost, making active account management accessible for SMEs who cannot justify full agency retainers.
