Amazon PPC is an auction-based advertising system where sellers and vendors bid on specific keywords or products to showcase their listings to high-intent shoppers. This model functions on a pay-per-click basis, meaning you incur costs only when a potential customer selects your advertisement. By utilizing Sponsored Products, Sponsored Brands, and Sponsored Display, sellers can effectively capture visibility throughout the entire customer journey, from initial discovery to the final purchase decision on the platform.
How does the Amazon PPC auction work?
The Amazon advertising auction uses a second-price model. This means that if you bid $2.00 for a keyword and the next highest bidder offers $1.50, you will only pay roughly $1.51 for the click. However, the highest bid does not always win the top placement. Amazon also considers a relevancy score, which includes factors like your product title, historical click-through rate (CTR), and conversion history.
In a typical account, the goal is to find the balance between a competitive bid and a high-quality listing. Amazon wants to show ads that are likely to result in a sale because they earn money from the click and the subsequent referral fee. If your listing has a poor conversion rate, you might find yourself needing to bid significantly higher than competitors to maintain the same ad position.
Sponsored Products: The foundation of Amazon ads
Sponsored Products are the most common ad type, appearing within search results and on product detail pages. These ads look nearly identical to organic listings, save for a small ‘Sponsored’ tag. They are highly effective because they target customers who are already searching for specific terms or viewing similar items.
Sellers can choose between automatic and manual targeting. In an automatic campaign, Amazon’s algorithm decides which keywords and products are relevant to your listing based on your category and content. In a manual campaign, you provide the specific keywords or ASINs (Amazon Standard Identification Numbers) you want to target. A common pattern is to use automatic campaigns for keyword discovery and then move successful terms into manual campaigns for tighter control.
- Broad Match: Includes your keyword in any order, including synonyms and related terms.
- Phrase Match: Requires the keyword to be in the exact order, but can include words before or after.
- Exact Match: The search query must match your keyword exactly, or very close variations.
- Negative Targeting: Prevents your ad from showing for specific terms that are irrelevant or unprofitable.
Which Amazon ad type should you prioritize?
Prioritization depends on your current business stage and inventory goals. For a new product launch, Sponsored Products are usually the first choice because they drive immediate sales and help improve organic ranking. If you have a registered brand and a growing catalog, Sponsored Brands can help you capture market share from competitors by showcasing multiple products at once.
For example, a Shopify store owner expanding to Amazon might start with Sponsored Products to test the waters. Once they see which items have the highest conversion rates, they can introduce Sponsored Brands to build a cohesive brand identity. Sponsored Display is often the final piece of the puzzle, used to re-engage shoppers who viewed your product but did not buy, or to target customers on a competitor’s listing page.
Sponsored Brands: Building brand equity
Sponsored Brands ads appear at the very top of search results, often featuring a custom headline, your brand logo, and up to three products. This format is available only to sellers who have completed the Amazon Brand Registry process. These ads are excellent for ‘top of funnel’ traffic, where users are searching for a category rather than a specific product.
One of the most effective sub-types within this category is Sponsored Brands Video. These ads appear in the middle of search results and play automatically as the user scrolls. Because video content is more engaging than static images, these often see higher click-through rates. Furthermore, you can link these ads directly to your Amazon Storefront, providing a distraction-free shopping environment away from competitor listings.
How do you calculate a profitable Amazon PPC budget?
Determining your budget requires an understanding of two key metrics: Advertising Cost of Sales (ACoS) and Total Advertising Cost of Sales (TACoS). ACoS measures your ad spend against the sales generated directly from those ads. TACoS measures your ad spend against your total sales (organic + paid). A healthy account often aims for a stable TACoS, as this indicates that ad spend is driving overall brand growth.
To find your break-even ACoS, subtract your cost of goods sold (COGS), shipping fees, and Amazon referral/FBA fees from your selling price. For instance, if you sell a product for $100 and your total costs are $70, your profit margin is 30%. In this scenario, your break-even ACoS is 30%. If your ACoS is below this number, you are making a profit on every ad-driven sale.
Sponsored Display and its role in retargeting
Sponsored Display is a unique ad type that allows you to reach audiences both on and off Amazon. Unlike Sponsored Products and Brands, which are keyword-based, Sponsored Display is primarily audience-based. You can target users based on their interests, shopping behaviors, or the specific products they have recently viewed.
A common strategy for Sponsored Display is ‘Views Remarketing.’ This targets shoppers who visited your product detail page in the last 30 days but did not complete a purchase. These ads appear on other Amazon pages, as well as third-party websites and apps. Additionally, you can use product targeting to place your ads directly under the ‘Add to Cart’ button on a competitor’s listing, offering a lower price or a better value proposition to undecided shoppers.
Optimizing campaigns for maximum ROI
Optimization is a continuous process of refinement. You should check your Search Term Report at least once a week to identify which queries are wasting money. If a keyword has received 20 clicks without a single sale, it is usually a candidate for a negative keyword. This prevents your budget from being drained by non-converting traffic.
Bid adjustments are another critical tool. Within the Campaign Manager, you can adjust bids by placement. For example, if you notice that your ads convert twice as well when they appear at the ‘Top of Search’ compared to ‘Product Pages,’ you can set a 50% or 100% bid increase for that specific placement. This ensures your budget is allocated to the locations where it performs best.
- Audit Search Term Reports: Identify and exclude low-performing terms every 7-10 days.
- Adjust Bids: Increase bids for keywords with low ACoS and decrease bids for high ACoS terms.
- Test Creative: Use different headlines and images in Sponsored Brands to see what resonates.
- Monitor Inventory: Pause campaigns for products that are low in stock to avoid wasting spend on items that might go out of stock.
Where to start your Amazon PPC journey this week
The best way to begin is by setting up a simple automatic campaign for your top-selling product. Let this campaign run for seven days with a modest daily budget, such as $20 or $50, to collect data. During this time, do not make any changes, as the algorithm needs time to calibrate and identify relevant audiences.
After the first week, download your Search Term Report and identify the keywords that generated sales. Create a new manual campaign using ‘Exact Match’ for these winning terms. This structured approach allows you to scale what works while maintaining control over your costs. Alien Road suggests keeping your campaign structure organized from day one to ensure long-term clarity in your reporting.
