Amazon CPC: how cost per click is set, and what you can afford
Amazon CPC, cost per click, is what you pay each time a shopper clicks your ad. This guide covers how Amazon's auction sets it, where to find your own numbers, how to work out the most a click is worth to you, and how to bring the cost down without losing sales.
Key takeaways
- Amazon sets CPC in an auction: your adjusted bid plus other factors Amazon does not publish. The final CPC never exceeds your maximum adjusted bid.
- Amazon publishes no average CPC. In Amazon's words, the more in demand the keyword or the more visible the placement, the higher the cost.
- Your own average CPC is spend divided by clicks; the Ads console reports it per campaign, target and search term.
- The most a click is worth: conversion rate times average order value times your target ACOS.
- Lower CPC by improving relevance and conversion, not only by cutting bids: a better listing raises what each click can earn.
What Amazon CPC is
Amazon CPC, cost per click, is the price you pay each time a shopper clicks one of your sponsored ads. Sponsored Products are always priced per click, and Sponsored Brands can be priced per click or per 1,000 viewable impressions. Amazon Ads describes PPC and CPC as two sides of one idea: PPC is paying per click, CPC is the metric for what each click costs.
Amazon Ads' CPC guide separates two figures. The maximum cost per click is the most you could be charged for a click: your base bid plus any adjustments, from settings such as dynamic bidding or placement adjustments. The average cost per click is what you actually paid, on average, across a period.
The difference matters when reading reports. A campaign with a $2.00 bid can show a lower average CPC, because the price is set by the auction, not by the bid alone. Amazon's best practices put it plainly: the final cost per click is based on your adjusted bid plus additional factors, and will never exceed your maximum adjusted bid.

How Amazon's auction sets your CPC
Amazon Ads says the final cost per click is usually determined by an auction and is based on your adjusted bid plus additional factors. Higher bids can help win better placements, but the auction considers factors beyond the bid in deciding both placement and price. Amazon does not publish what those factors are.
What Amazon does say is directional: generally, the more in demand a keyword is or the more visible the placement, the higher the cost. Top of search on a popular category keyword is the expensive end; a product page placement on a narrow long tail search is usually the cheaper end.
Guides elsewhere often describe Amazon's auction as a second price auction. Amazon Ads' own pages do not describe it that way, so this guide does not either. What is certain is the ceiling: you never pay more than your maximum adjusted bid for a click.
| Setting | What it does to your CPC, per Amazon Ads |
|---|---|
| Base bid | Sets the starting maximum for a keyword or target |
| Dynamic bids, up and down | Amazon adjusts the bid up or down using real time signals |
| Dynamic bids, down only | Amazon may lower the bid using real time signals, never raise it |
| Fixed bids | Amazon uses exactly your bid |
| Placement adjustments | Raise the bid for top of search, rest of search or product pages, by up to 900% |
Where to find what you pay per click
Your average cost per click is spend divided by clicks, and the Amazon Ads console reports it at every level: campaign, ad group, keyword or target, and search term. Amazon's report list includes several that show CPC from different angles.
| Report | What it shows about CPC |
|---|---|
| Performance over time | Clicks and spend over time, with average cost per click: whether click costs are rising |
| Search term report | CPC for each customer search term with at least one click, and its sales |
| Targeting report | CPC and sales for each keyword and product target |
| Placement report | Top of search compared with other placements |
| Search term impression share | Your share and rank of impressions on each term against other advertisers |
An average hides the spread. The same campaign can pay very different prices per click for its broad match discovery terms and its exact match best sellers. Read CPC at the level of the keyword and the placement, next to the sales each one brings, before deciding anything about the campaign.
Is there an average Amazon CPC?
Amazon does not publish an average cost per click, for any category or for Amazon as a whole. Figures you see online come from third party tools and agencies, measured across whichever accounts they manage, mixing categories, match types, placements and dates. They are not a benchmark for your product.
Amazon Ads' CPC guide says the rank of ads changes frequently, so there is no set number for a brand's CPC. The useful question is not what others pay, but what a click is worth to you: the next section works that out from your own numbers.
Keyword demand
Amazon: the more in demand the keyword, the higher the cost.
Placement visibility
Amazon: the more visible the placement, the higher the cost.
Match type
Exact match is the most restrictive; Amazon suggests the highest bid on exact.
Season
Demand shifts around events such as Prime Day and the holidays.
How much you can afford per click
The most a click is worth follows from Amazon's own definition of ACOS, ad spend divided by ad sales. A click costs your CPC. On average, a click brings in your conversion rate times your average order value in sales. So the ACOS of a keyword equals CPC divided by conversion rate times order value, and the highest CPC you can pay at a target ACOS is:
Max CPC = conversion rate x average order value x target ACOS
Take an illustrative product: a $30 average order, a 10% conversion rate from ad clicks, and a target ACOS of 25%. Each click brings $3 of sales on average, and at a 25% target you can pay up to $0.75 per click. Bid above that and the keyword's ACOS rises above target; bid below and it sits under.
The chart shows the lever most CPC advice skips: conversion rate. Doubling conversion doubles what you can afford per click at the same ACOS. A better listing does not make clicks cheaper in the auction, but it makes each click worth more, which is what decides whether a CPC is affordable. Set the target ACOS from your margin with our ACoS calculator.
How to lower Amazon CPC without losing sales
Amazon Ads names three ways to improve a keyword strategy after about two weeks of data: refine match types, add new keywords, and add negative keywords. Each one lowers the cost of a sale, which is what matters more than the raw price of a click.
Lowers cost without losing sales
- Negative keywords on searches that click and never convert
- Exact match on proven searches, with the bid set from max CPC
- Dynamic bids, down only, on campaigns where conversion varies
- Placement adjustments only where the placement report shows it pays
- A better main image, title and price, raising click through and conversion
Lowers CPC and loses sales
- Cutting every bid by the same amount
- Pausing converting keywords because their CPC looks high
- Dropping top of search where it sells best
- Moving all budget to broad match for cheaper clicks
- Chasing the lowest CPC instead of the lowest cost per sale
A high CPC on a keyword that converts is often the best money in the account; a low CPC on one that never sells is the worst. Judge every keyword by its ACOS, not its CPC. Our negative keywords guide covers the first lever in detail.
CPC, budgets and bidding strategy
CPC and budget work together. Amazon Ads describes the daily budget as an amount averaged over the calendar month, recommends at least $10 a day in the US, and advises adding budget when campaigns run out during the day. When a campaign runs dry by midday, its CPC data only covers the morning, and the cheapest searches of the afternoon never get a chance.
Bidding strategy sets how CPC moves within that budget. Amazon Ads suggests the highest bid on exact match, lower on phrase and lowest on broad for the same keyword, since exact tends to convert best. Competition can shift with the season: around events such as Prime Day and the holidays, more demand can mean a bid that won auctions last month wins fewer.
| Situation | Effect on CPC and spend | What to do |
|---|---|---|
| Budget runs out early in the day | Fewer auctions entered; data skewed to morning | Raise budget if ACOS is within target, or lower bids |
| Peak season competition | The same bid may win fewer auctions | Raise bids on proven converters for the window only |
| Low click through rate | Clicks cost the same, but fewer shoppers click | Fix main image, title and price before raising bids |
| Broad match spending most of the budget | Many cheap clicks, few sales | Move budget to exact match and add negatives |
Click through rate, the share of shoppers who click after seeing the ad, is the other side of cost. A low CTR means impressions that never become clicks; the CPC stays the same, but the campaign reaches fewer shoppers for its budget. Display ads, which Amazon prices through automated bidding rather than a set CPC, follow different rules and belong in a separate budget.
CPC vs CPM on Amazon
Amazon Ads' CPC guide contrasts two pricing models. CPC is based on actual clicks; CPM, cost per mille, is based on every 1,000 times an ad is viewed, whether or not anyone clicks. Sponsored Brands can use vCPM, which counts only viewable impressions.
Amazon's guide sums up the trade: CPC is more directly tied to purchases, while CPM can suit a goal such as brand awareness. For most sellers running Sponsored Products, CPC is the only model and the right one. CPM belongs in campaigns built for reach, judged on reach and new to brand orders rather than on clicks.
| CPC | vCPM | |
|---|---|---|
| You pay for | Each click | Each 1,000 viewable impressions |
| Available on | Sponsored Products, Sponsored Brands | Sponsored Brands |
| Suits | Sales from shoppers ready to buy | Brand awareness and reach |
| Judge it by | ACOS and conversion | Reach, impressions, new to brand orders |
Cost per click mistakes
Benchmarking against published averages
Amazon publishes none; outside averages mix categories and dates.
Bidding without a max CPC
Without conversion rate and order value, a bid is a guess.
Reading CPC without sales
A cheap click that never converts costs more per sale than an expensive one that does.
Stacking adjustments blindly
Dynamic bids and placement adjustments of up to 900% can lift the ceiling far above the base bid.
Ignoring conversion
A better listing raises what every click is worth.
Judging too early
Amazon Ads suggests about two weeks of data before keyword decisions.

What is the average CPC on Amazon?
Amazon does not publish one. Online averages come from third party tools and mix categories, match types and dates. What a click is worth to you depends on your conversion rate, order value and target ACOS.
Why is my Amazon CPC so high?
Amazon says in demand keywords and visible placements cost more. Also check placement adjustments and dynamic bids up and down, which can raise the ceiling above your base bid.
How do I calculate my maximum CPC?
Multiply your conversion rate by your average order value by your target ACOS. For an illustrative $30 order, 10% conversion and a 25% target, that is $0.75 per click.
How do I lower my Amazon CPC?
Add negative keywords, move budget to exact match on proven searches, use dynamic bids down only where conversion varies, and improve the listing so each click converts more often.
Is a high CPC bad?
Not by itself. A high CPC on a keyword that converts well can have a low ACOS. Judge keywords by cost per sale, not by the price of a click.
What is the difference between CPC and CPM on Amazon?
CPC charges per click; CPM, or vCPM on Amazon, charges per 1,000 viewable impressions. Amazon Ads says CPC ties more directly to purchases, while CPM can suit brand awareness.
Does a better listing lower CPC?
It lowers the cost of each sale, and raises the CPC you can afford, because more clicks convert. Amazon does not say how its auction weighs the listing in the price of a click.
Where can I see CPC in the Amazon Ads console?
Campaign Manager shows average CPC per campaign, ad group and target, and reports such as the search term, targeting and performance over time reports show it by search term and over time.
