What is Amazon PPC and how does it work?
Amazon PPC is Amazon’s pay-per-click advertising: you bid on keywords or products, your ad appears in search results or on product pages, and you pay only when a shopper clicks. It runs through Sponsored Products, Sponsored Brands and Sponsored Display, and pays off when bids are set against your profit margin, not guesswork.

By Asad Razzaq, Senior Amazon PPC StrategistUpdated 1 November 2026How does Amazon PPC actually work?
Every time a shopper searches on Amazon or opens a product page, Amazon fills a set of ad slots through an auction. You tell Amazon which searches or products you want to appear against, how much you are willing to pay for a click, and how much you want to spend each day. Amazon weighs your bid alongside how relevant your product is to that search, then decides whose ad to show. You never pay more than your bid, and you pay nothing for an impression that is not clicked.
Relevance matters as much as money. A high bid on a search term that does not match your listing will struggle to win impressions, and if it does win, shoppers will not click or buy. This is why Amazon PPC and your product listing are one system: the listing earns the click and the sale, and the ads buy the visibility.
Sales from ads also count towards your product’s overall sales history. Many sellers see organic rank improve on search terms where ads drive steady, profitable sales. That is the real reason to advertise on Amazon: not only the sales the ads generate directly, but the effect those sales have on how often you appear without paying.
What ad types does Amazon offer?
Three self-service ad types cover most of what a private-label brand needs.
| Ad type | Where it appears | Who can use it | Good for |
|---|---|---|---|
| Sponsored Products | In search results and on product detail pages, looking like a normal listing | Professional sellers and vendors | The core of almost every account: driving sales on specific keywords and products |
| Sponsored Brands | Banner-style placements in search, often at the top, showing your logo, headline and several products or a video | Brand-registered sellers and vendors | Brand awareness, branded search defence and sending shoppers to your Store |
| Sponsored Display | Product pages, around the web and in apps, depending on targeting | Brand-registered sellers and vendors | Retargeting shoppers who viewed your products and targeting competitor pages |
How should you structure Amazon PPC campaigns?
A clean structure separates research from performance. Start with an automatic campaign, where Amazon chooses the searches and products to show your ad against based on your listing. Its targeting groups (close match, loose match, substitutes and complements) let you see which customer searches turn into orders.
Run manual campaigns alongside it. In manual keyword targeting you choose the keywords and a match type: broad match reaches the widest set of related searches, phrase match requires the phrase to appear in the search, and exact match targets that search and close variants only. Manual product targeting lets you bid on specific ASINs or whole categories.
The weekly routine that makes this work is called search-term harvesting. You read the search term report, move the searches that convert into exact-match campaigns where you control the bid, and add the searches that spend without selling as negative keywords so they stop wasting money. Group campaigns into portfolios by product line so budgets and results are easy to read.
Keep campaigns small enough to control. One product line per campaign, one match type per ad group and a clear naming convention will save you hours every month and make it obvious where money is going.
Which numbers matter in Amazon PPC?
These are the formulas behind every Amazon PPC report. The figures in the last column are hypothetical.
| Metric | Formula | Example |
|---|---|---|
| ACoS (advertising cost of sales) | Ad spend / ad sales | Example: £200 spend / £800 ad sales = 25% |
| ROAS (return on ad spend) | Ad sales / ad spend = 1 / ACoS | Example: £800 / £200 = 4x, the same as a 25% ACoS |
| TACoS (total advertising cost of sales) | Ad spend / total sales (paid and organic) | Example: £200 / £2,000 total sales = 10% |
| CPC (cost per click) | Ad spend / clicks | Example: £200 / 250 clicks = £0.80 |
| CTR (click-through rate) | Clicks / impressions | Example: 250 / 50,000 = 0.5% |
| CVR (conversion rate) | Orders / clicks | Example: 40 orders / 250 clicks = 16% |
| Break-even ACoS | Profit margin before ad costs, as a % of selling price | Example: a £20 product leaving £6 after product cost, Amazon fees and VAT has a 30% break-even ACoS |
How do you launch your first Amazon PPC campaign?
A sensible order for a new product or a first account.
Step 1
Work out your break-even ACoS
Take the selling price, subtract product cost, Amazon fees and, on Amazon UK, VAT. What is left as a percentage of price is the most you can spend on ads per sale before you lose money.
Step 2
Make sure the listing is ready
Ads amplify whatever the listing does. Check the title, images, bullet points, price and reviews before you spend, and make sure you hold the Buy Box, because Sponsored Products ads generally only show when your offer is the featured offer.
Step 3
Launch an automatic campaign
Give it a modest daily budget and let it gather search-term data for one to two weeks before you judge it.
Step 4
Add manual exact and phrase campaigns
Use your keyword research and the first converting search terms to build manual campaigns with bids set against your target ACoS.
Step 5
Harvest, negate and adjust weekly
Every week, promote converting search terms to exact match, add non-converting ones as negatives and move bids towards your target.
What good looks like in a real account
In a UK private-label account we manage, monthly ROAS ran between 8.5x and 12.8x from March to October 2026, above 10x in six of those eight months, while TACoS stayed at about 3%. Ordered product sales for January to October 2026 were up 100% on the same period of 2025. Numbers like these come from disciplined weekly search-term work and bids set against margin, not from one clever setting.
What mistakes waste Amazon ad budget?
- Judging campaigns on ACoS without knowing your break-even ACoS
- Never reading the search term report, so irrelevant searches keep spending
- Running broad match with no negative keywords
- Advertising products that are out of stock, lose the Buy Box or have weak listings
- Raising bids on keywords that get clicks but never convert
- Letting campaign budgets run out by midday so you miss the evening shoppers
- Ignoring TACoS, so you cannot tell whether ads are growing total sales
- Changing too many things at once, so you never learn what worked
Frequently asked questions
How much should I spend on Amazon PPC?
Spend what your margin and goals support. Start from your break-even ACoS, set bids that keep you under it on proven keywords, and allow a higher ACoS only for deliberate launches or rank pushes.
How long does Amazon PPC take to work?
You will see clicks and sales within days, but campaigns usually need two to four weeks of data before bid and keyword decisions are reliable. Profitability improves through weekly optimisation, not in the first week.
Is Amazon PPC worth it for small sellers?
Yes, if the product has a healthy margin and a listing that converts. A small budget focused on a few relevant exact-match keywords is often more profitable than a large, loosely targeted one.
What is a good ACoS on Amazon?
A good ACoS is one below your break-even ACoS that still lets you grow. That number depends on your margin, so a 15% ACoS can lose money on one product and be very profitable on another.
Do I need Brand Registry to run Amazon ads?
No for Sponsored Products, which any professional seller can run. You need Brand Registry for Sponsored Brands, Sponsored Display and Stores.

ACoS vs TACoS
ACoS measures ad spend against the sales your ads directly generated; TACoS measures ad spend against all your sales, paid and organic.
How to lower ACoS
To lower ACoS, cut search terms that spend without selling, set bids from a target ACoS instead of guessing, move budget to placements and keywords that convert, and improve the listing so more clicks become orders.
