Amazon Ads: Do They Work, or Just Drain Your Budget?

Amazon Ads webpage

Amazon is no longer a place where you can just list a product and let the cash register ring on its own—it’s a pay-to-play battleground where visibility comes with a price tag.

That was a hard pill to swallow when I decided to branch out into a new product category. I was so used to the built-in reach of my old store that I overlooked just how cutthroat the marketplace had become. Organic traffic alone wasn’t cutting it anymore—visibility had become a premium currency.

So, how do you break through the noise? You advertise, of course. And by that, I mean you invest in Amazon’s sponsored spaces—because let’s be real, this isn’t a game where you can just toss in pocket change and expect big returns.

But before we dive into that, let’s clear something up—it’s not about whether ads can actually boost your sales. If advertising didn’t work, brands wouldn’t be shelling out billions every year to stay in the spotlight.


  • Amazon Ads require strategic planning and continuous optimization to be effective, not just high bids.
  • Choosing the right keywords and targeting strategies, like bidding on high-intent, long-tail keywords, is crucial for ad success.
  • Ads should be monitored and adjusted regularly to avoid wasting money on underperforming keywords.
  • Effective Amazon Ads can boost visibility and sales, especially when launching new products or competing in crowded markets.
  • Timing is key; using ads during product launches or seasonal peaks can significantly enhance their impact.

The real question you should be asking is: How do you make sure your ads actually work?

Because let’s face it—Amazon Ads isn’t some secret cash stream anymore. It’s an arena packed with deep-pocketed competitors, all vying for the same customers. And if you don’t play your cards right, your ad budget could go up in smoke before you see a single worthwhile return.

To prove just how powerful Amazon Ads can be in driving sales and setting online businesses up for success, here are some compelling case studies worth checking out:

How exactly does Amazon Ads work?

First things first—you need to know what you’re signing up for. Many Amazon sellers throw money at ads, hoping for magic, only to watch their budgets disappear with little to show for it. That’s because they only know half the story.

Amazon Advertisements or Amazon Ads is no longer just about bidding high and hoping for sales. It’s about strategy, smart targeting, and constant optimization. If you don’t understand how the system works, you’re leaving profit on the table.

Imagine opening a coffee shop in a city where thousands of others are already competing for customers. You could rent a spot on the busiest street and hope foot traffic brings in sales, but if your signage is dull and your promotions aren’t compelling, people will walk right past you.

Amazon Ads works the same way. Just because your ad appears in search results doesn’t mean shoppers will click on it—or more importantly, buy. You need the right messaging, the right audience, and the right bidding strategy to make it worth your while.

pay-per-click

Amazon Ads operates on a pay-per-click (PPC) system, meaning you only pay when someone clicks on your ad. It sounds great in theory—you’re not paying for visibility, only for engagement. But here’s the catch: not all clicks turn into sales.

If your ad brings in shoppers who aren’t actually interested in your product, you’re burning money without seeing a return.

Let’s say you’re selling a set of premium, stainless steel chef’s knives. You decide to run a Sponsored Products campaign, bidding on the keyword “kitchen knives.”

Sounds reasonable, right? The problem is, “kitchen knives” is a broad term—some people searching for it might be looking for a cheap $10 knife, while others might want a full set of high-end blades.

If someone clicks your ad expecting a budget-friendly knife and sees your $120 premium set instead, they’re likely to bounce without buying. You just paid for that click, but got nothing in return.

Now, a smarter strategy would be to bid on more specific, high-intent keywords like “professional chef knife set” or “Japanese steel kitchen knives.”

These are long-tail keywords that attract buyers who are more likely to convert because they’re actively looking for what you’re selling. Instead of wasting your ad budget on unqualified traffic, you’re narrowing your audience to people who actually want your product.

But targeting the right keywords is only half the battle. Amazon also allows you to run ads on competitor product pages. This is where things get really interesting.

Suppose your main competitor is a well-known brand selling a similar knife set for $150. If you strategically place your ad on their product page, shoppers who are considering that product might notice your slightly cheaper yet high-quality alternative.

That’s like opening your coffee shop right next to Starbucks and putting up a sign that says, “Same great taste, better price.” You’re leveraging existing traffic and diverting it to your own business.

Another key element of Amazon Ads is bidding strategy. Many sellers assume that the highest bid wins the ad placement, but that’s not exactly how it works. Amazon uses a second-price auction system, meaning you only pay one cent more than the next highest bidder.

If you bid $2 per click and your competitor bids $1.50, you don’t actually pay $2—you pay $1.51. That means blindly setting high bids doesn’t guarantee success, but strategic bidding does.

Amazon also offers automatic and manual campaigns. Think of automatic campaigns like setting your coffee shop in a high-traffic area without choosing a specific target audience—Amazon decides which keywords your ad will appear for.

It’s a great way to gather data, but it can be inefficient. Manual campaigns, on the other hand, let you handpick your keywords and adjust bids accordingly.

This is where you can fine-tune your strategy. You can bid aggressively on high-performing keywords and lower bids on those that don’t convert well.

One of the biggest mistakes sellers make is setting up ads and forgetting about them. Amazon Ads requires constant monitoring and optimization. You wouldn’t open a coffee shop, launch an ad in a newspaper, and then never check if it’s actually bringing in customers.

The same goes for Amazon. You need to analyze which keywords are working, tweak your bids, and eliminate wasteful spending on poor-performing terms.

So, does Amazon Ads work? Absolutely. But only if you work it the right way. If you treat it like a set-it-and-forget-it strategy, you’ll watch your budget drain without much return.

But if you approach it like a calculated business move—optimizing bids, refining keywords, and strategically placing your ads where they matter—you can turn it into a powerful tool for driving sales and scaling your brand.

When should you run Amazon ads?

Timing is everything in business, and Amazon Ads is no exception. Running ads at the right moment can be the difference between wasting money on clicks that don’t convert and strategically boosting your sales and brand presence. So when does it make the most sense to invest in Amazon Ads?

1. When Launching a New Product

 Think of launching a product on Amazon like opening a brand-new restaurant. No one knows about it yet, so even if you have the best food in town, customers won’t just magically walk in. You need advertising to get your name out there.

Amazon’s ranking algorithm heavily favors products that generate consistent sales. But how do you generate sales if no one can find your product? This is where Amazon Ads bridge the gap between launch and organic ranking.

Sponsored Product ads can place your product at the top of search results, immediately putting it in front of shoppers. The more sales you generate through ads, the faster Amazon starts ranking your product organically, reducing your dependence on paid traffic over time.

For example, let’s say you’re launching a new brand of ergonomic office chairs. Without ads, you’re buried under thousands of similar listings, and customers may never scroll far enough to see your product.

But with a well-targeted Amazon Ads campaign, your chair could appear right at the top of the search results when someone looks up “best ergonomic chair.”

If your product stands out with strong images, competitive pricing, and great initial reviews, those ads kickstart your momentum and help you climb the organic rankings faster.

2. When Competing in a Crowded Market 

Let’s face it—Amazon is a war zone in many categories. If you’re selling something highly competitive like phone accessories, kitchen gadgets, or fitness gear, the competition is ruthless.

Without advertising, you’ll be drowned out by established brands with thousands of reviews and a dominant presence.

This is where Amazon Ads can level the playing field. Instead of waiting months (or years) for organic traffic, you can use Product Targeting Ads to steal traffic from top competitors.

Imagine you’re selling a high-end blender for $99, while a big-name brand dominates the category with a $150 model. By placing your ad directly on their product page, you’re offering shoppers a visible, cheaper alternative at the exact moment they’re making a decision.

This strategy works especially well in price-sensitive markets, where shoppers actively compare options before buying.

3. During Seasonal Peaks and High-Demand Periods

 There’s a reason stores go all out with advertising before Black Friday. Peak shopping seasons mean peak buying intent. Amazon Ads become even more effective when demand naturally surges, making every advertising dollar go further.

Let’s say you sell holiday-themed baking kits. Throughout most of the year, demand is lukewarm at best. But as soon as November hits, people start searching for gingerbread house kits and festive cookie cutters.

If you launch an Amazon Ads campaign during this time, your chances of converting shoppers into buyers skyrockets. Similarly, if you sell fitness equipment, January is where the money’s at. Every year, searches for workout gear spike as people commit to their New Year’s resolutions.

If you wait until mid-January to start running ads, you’ve already missed the biggest rush. Instead, launch your ads early and position your product right in front of buyers at the peak of their interest.

4. When Your Organic Sales Start to Plateau

 Even the best-selling products hit a ceiling at some point. If your sales have been growing steadily but suddenly start flatlining, it’s a sign that you may need to inject some fuel into your marketing strategy.

Amazon Ads can help break through that plateau by reigniting visibility, driving more traffic, and getting you in front of new customers who may not have found you otherwise.

For instance, if you sell a line of eco-friendly water bottles, you might notice that after months of strong growth, your daily sales numbers start to stagnate. This could be because new competitors have entered the market or because Amazon’s algorithm has shifted rankings.

Running a Sponsored Brands campaign can reinforce your brand’s presence and help recapture momentum.

5. When Expanding Into New Markets

 Amazon has global reach. If you’re expanding to new regions like Canada, the UK, or Germany, visibility is your first hurdle. Just because your product sold well in the US doesn’t mean international shoppers will automatically find it.

Running Amazon Ads in new markets is like putting up a neon sign that says, “Hey, we’re here!” It helps build brand awareness and quickly attract a local customer base instead of waiting for organic sales to pick up.

For example, if you’re launching a skincare line in Japan, your brand is starting from scratch. Shoppers won’t be searching for you by name, so targeting broad, high-intent keywords like “hydrating face serum” through Sponsored Products ads can drive those crucial first sales. 


If you’re launching a new product, battling heavy competition, capitalizing on seasonal trends, reigniting a plateaued product, or expanding into new markets, Amazon ads can give you the competitive edge you need.

But if you just set them up and walk away, you’ll quickly learn the hard way that Amazon will gladly take your money without guaranteeing results.

Success with Amazon Ads comes down to strategy, timing, and continuous optimization. Play your cards right, and it won’t just boost your sales—it will set your business up for long-term profitability.
