What are Amazon PPC ads?
Amazon PPC ads are pay-per-click ads that sellers buy inside Amazon, mainly Sponsored Products, Sponsored Brands and Sponsored Display. You bid on keywords or products, and you pay when a shopper clicks, not when the ad is shown. They work when the bid and budget are set from your real margin. The number to know first is your break-even ACOS: the share of ad sales you can spend on advertising before the product loses money.
TL;DR
- Amazon PPC has three main ad types: Sponsored Products (individual listings), Sponsored Brands (brand and several products) and Sponsored Display (retargeting and product pages). Most new sellers start with Sponsored Products.
- ACOS is ad spend divided by ad sales. ROAS is the inverse. TACoS is ad spend divided by total sales, including organic. Break-even ACOS equals your profit margin before ads.
- A worked example below: a $30 product with $11 of margin before ads breaks even at 36.7% ACOS, which turns into a maximum bid of $0.90 at a 10% conversion rate and a 30% target ACOS.
- The cheapest way to learn is an automatic campaign to discover what shoppers search, then moving winners into manual exact match campaigns.
- Pause or lower bids on terms with enough clicks and no sales. The click count to wait for is a function of your conversion rate and price, shown in a table below.
- Fees, ad formats and tools change. Use the numbers here as a method, plug in your own costs and confirm current options in Amazon Ads.

Which Amazon PPC ad types should you use?
| Ad type | What it promotes | Where it appears | Best used for |
|---|---|---|---|
| Sponsored Products | One product listing | Search results and product pages | Almost every seller; the default starting point |
| Sponsored Brands | Your brand logo, a headline and several products or a store page | Top of search results and other placements | Brand awareness and multi-product discovery, once you have a catalog |
| Sponsored Display | Products and brand, with audience targeting | On and off Amazon, including retargeting | Defending your listings and reaching past visitors |
Ad names, placements and eligibility change over time, so confirm current details in Amazon Ads before you build. Most accounts earn their first reliable data from Sponsored Products.
What do ACOS, ROAS and TACoS mean?
| Metric | Formula | What it tells you |
|---|---|---|
| ACOS | Ad spend / ad-attributed sales | How much you pay for each dollar of ad sales |
| ROAS | Ad-attributed sales / ad spend | The same information, inverted |
| TACoS | Ad spend / total sales (ad plus organic) | Whether advertising is building organic sales or replacing them |
| Break-even ACOS | Profit margin before ads / price | The ACOS at which advertising makes zero profit |
| Target ACOS | Below break-even, by your growth goal | What you manage campaigns to |
A rising TACoS with flat total sales means you are paying for sales you would have made anyway. A falling TACoS with growing total sales usually means ads are lifting organic rank. Our guide to shopping ad performance covers similar metrics for Google.
Worked example: what can this product afford to pay for a click?
The inputs are invented: a $30 product, $9 cost of goods and $10 of Amazon fees and fulfillment. Use your own numbers.
| Step | Calculation | Result |
|---|---|---|
| Margin before ads | $30 – $9 – $10 | $11 |
| Break-even ACOS | $11 / $30 | 36.7% |
| Target ACOS (growth goal) | You choose; leave room for profit | 30% |
| Conversion rate (orders per click) | From your data; assumed here | 10% |
| Maximum bid | $30 x 10% x 30% | $0.90 |
At a $0.90 bid and a 10% conversion rate, ten clicks cost about $9 and produce one $30 sale, which is 30% ACOS. If the real conversion rate is 5%, the same bid produces a 60% ACOS and loses money, because break-even is 36.7%. Conversion rate is the lever that matters most, which is why listing quality comes before bidding. Improve images, title, reviews and price before you raise bids.
How many clicks should you wait for before pausing a keyword?
If a keyword really converts at a given rate, the chance of seeing zero sales in n clicks is (1 – rate) to the power n. The table finds the number of clicks where that chance falls under 5%, and what those clicks cost at the $0.90 bid.
| True conversion rate | Clicks with no sale before you can be fairly sure it is not working | Spend at a $0.90 bid |
|---|---|---|
| 5% | 59 | $53 |
| 10% | 29 | $26 |
| 15% | 19 | $17 |
A keyword with 8 clicks and no sale tells you almost nothing. A keyword with 40 clicks and no sale at a price like this is probably wasting money. The thresholds rise for low-conversion, high-price products.
How should you structure Amazon PPC campaigns?
| Campaign | Targeting | Purpose | Budget share to start |
|---|---|---|---|
| Automatic | Amazon chooses keywords and products | Discover search terms and competing products | About half while you are learning |
| Manual, exact match | Your proven keywords, exactly | Spend on terms with sales; control bids | Grows as winners are found |
| Manual, phrase and broad | Variations of your main terms | Controlled expansion | Small |
| Product targeting | Specific competing or complementary listings | Show up on competitor pages | Small, tested one at a time |
| Defensive brand | Your own brand terms | Protect your name from competitors | Small and cheap |
The standard loop is: run automatic campaigns, read the search-term report, move terms that sold into exact match, add the terms that wasted money as negatives, and repeat every week. Our PPC keyword research guide explains the thinking that applies on any platform.
What does a weekly Amazon PPC routine look like?
| Task | How often | What to look at |
|---|---|---|
| Search-term report | Weekly | Terms with sales to promote; terms with spend and no sales to negate |
| Bid adjustments | Weekly | Lower bids where ACOS is above target; raise where it is far below and the product is in stock |
| Budget pacing | Daily check | Campaigns running out of budget early on good days |
| Placement report | Every two weeks | Top of search versus other placements |
| Listing check | Monthly | Price, images, reviews and stock status, which change conversion |
| TACoS review | Monthly | Whether ad spend is building organic sales |
If you also advertise on Google, the same discipline applies there: see how PPC works across platforms, what Google Ads budgets and management fees look like, and how conversion rate optimization lifts the number that sets your maximum bid. Our online marketplace marketing services extend this to other marketplaces.
When should you not run Amazon PPC?
| Situation | Why | Do first |
|---|---|---|
| Out of stock or low stock | Ads spend money on a listing that cannot ship | Fix inventory; see inventory management |
| Thin margin | Break-even ACOS is too low to bid competitively | Fix price, cost or fees |
| Few or poor reviews | Shoppers click and do not buy | Improve the product and listing first |
| Listing has weak images or title | Low conversion makes every click expensive | Rewrite the listing |
| Product is a poor fit for the category | Clicks are cheap but no one buys | Test demand before scaling spend |
What mistakes burn an Amazon ad budget?
| Mistake | What happens | Fix |
|---|---|---|
| Bidding without knowing break-even ACOS | You scale a product that loses money on every sale | Calculate margin before ads first |
| Leaving broad match and automatic running unattended | Spend drifts to irrelevant terms | Review search terms weekly and add negatives |
| Judging a keyword after a handful of clicks | You cut winners and keep noise | Use a click threshold based on conversion rate |
| Ignoring organic rank | You pay for sales that organic would have delivered | Track TACoS and rank together |
| One campaign for everything | You cannot see what works | Separate discovery from proven terms |
| Running ads on a weak listing | Low conversion inflates ACOS | Improve images, title and reviews first |

Frequently Asked Questions
What are Amazon PPC ads?
They are pay-per-click ads sold inside Amazon, mainly Sponsored Products, Sponsored Brands and Sponsored Display. You bid on keywords or products and pay when a shopper clicks the ad.
How does Amazon PPC work?
You create a campaign, choose targeting and a bid, and Amazon enters your ad into an auction when a shopper searches or views a related page. You pay per click, and results are reported as spend, sales and ACOS.
What is a good ACOS on Amazon?
There is no universal number. The right target depends on your margin. Break-even ACOS equals your profit margin before ads divided by price, so a good target is below that number by the amount of profit or growth you want.
What is the difference between ACOS and ROAS?
ACOS is ad spend divided by ad sales. ROAS is ad sales divided by ad spend. They carry the same information, so a 25% ACOS equals a ROAS of 4.
What is TACoS?
Total Advertising Cost of Sale is ad spend divided by total sales, including organic. It shows whether advertising is lifting your overall sales or just paying for sales you would have made anyway.
How much should I spend on Amazon PPC?
Start from your break-even ACOS and your goal. A new product often needs a learning budget for discovery, but spend should always be tied to what the product can afford to pay for a click.
Which Amazon ad type should I start with?
Most sellers start with Sponsored Products, because it promotes a single listing and is simple to measure. Add Sponsored Brands and Sponsored Display once you have a catalog and data.
What is the difference between automatic and manual campaigns?
Automatic campaigns let Amazon choose the keywords and products to target. Manual campaigns let you choose them. Many sellers use automatic campaigns to discover terms, then move winners into manual exact match.
Can Amazon PPC improve my organic ranking?
Sales from ads can support organic ranking on those keywords, but ranking depends on many factors, including conversion rate, price, reviews and availability, and Amazon does not publish the exact formula.
Should I hire an agency for Amazon PPC?
It depends on your time, catalog size and ad spend. Compare providers on reporting transparency, how they set targets from margin and how they handle search-term management.
Bottom Line
Amazon PPC works when the bid comes from your margin, not from a guess. Work out break-even ACOS, wait for enough clicks before cutting, separate discovery from proven terms and fix the listing before you pour money into it.
