CPM is one of the most common pricing models in digital marketing. It’s a go-to model for companies who want their ads to reach a wide audience (and who doesn’t?).
But even though CPM seems to be everywhere, it’s often misunderstood. So what is CPM and when should you use it? Keep reading for answers to these questions — and more.
Key Takeaways
What does CPM stand for? That would be cost per mille, sometimes called cost per thousand or cost per 1,000 impressions. This ecommerce metric represents how much money an advertiser pays for 1,000 impressions of their ads on a web page. It’s expressed as a dollar amount.
“Mille” is a Latin-derived French word meaning “thousand.” Traditional print and broadcast advertisers paid per thousand readers or viewers, and when digital advertising began in the 1990s, marketers adopted this terminology, according to a Journal of Economic Perspectives article.
In order to use CPM in advertising, you have to first understand what an impression actually is.
Some people use impressions, page views, and even clicks interchangeably. But these are three entirely different metrics.
Impressions count every time an element of a web page (usually an ad) loaded and appeared for a viewer. Google defines impressions as viewable if “at least 50 percent of its area is visible for at least 1 second for display ads, or at least 2 seconds for video ads.”
Page views count every time a user visits or loads a web page. Clicks count every time a user clicks an ad or another digital element and visits another page. Both of these are measures of deeper engagement or performance. Impressions are instead about visibility. In other words, CPM is a measure of how much you’re paying for visibility, not for traffic or conversions.
Visibility is still important, though. Impressions tell you how often your ad appeared in a place where potential customers might notice it. That reach helps drive awareness, and it also comes in handy for retargeting campaigns. It’s also typically how video, display, and programmatic advertising are sold in media buying.
Now that you know the CPM definition, it’s time to learn how to find yours.
To calculate CPM, divide your total campaign cost by the number of impressions it received. Then multiply that number by 1,000.
Here’s the CPM formula: CPM = (Total Cost ÷ Total Impressions) × 1,000
By focusing on the total cost and total impressions in a single campaign, CPM standardizes cost across campaigns of different sizes. No matter how big or small your campaign, you’ll always get that standardized result of the cost of 1,000 impressions.
Let’s take a closer look at each variable in the CPM formula:
You can also easily rearrange these variables to solve for total spend or total impressions, which can help you with campaign planning. Here’s how those revised formulas look:
Picture a small ecommerce business that sells handmade scented candles online and runs digital ads on social media. They launch a new campaign to promote a seasonal scent, and they want to track how efficiently they’re reaching new customers using CPM.
CPM advertising works best when your goal is exposure and awareness from a large audience. That makes it ideal for:
Take a look at these ad pricing models at a glance.
CPM isn’t the only way ecommerce businesses can price digital advertising. Here’s how it measures up against some other popular options, according to Foundations in Digital Marketing.
Cost per click, or CPC, is the cost to your business for every click on an ad, not an impression like in CPM. This means it’s more directly tied to engagement than CPM, which is all about visibility and charges you for your ads whether or not anyone interacts with them.
That makes CPM a better choice for reaching a large audience and building brand awareness. CPC, on the other hand, is a better choice for driving traffic, lead generation, and any other campaigns where click intent is more important.
Cost per action (also sometimes called cost per acquisition) or CPA is the cost to your business per a specific action. That action might be a purchase, a download, or a sign-up — you can think of it as any desired action you want a user to take — not just a click, like in CPC, or an impression, like in CPM. That makes it much more performance-oriented than the other two.
CPA usually costs more because conversions can take multiple steps, but the conversions may be worth the cost, depending on your business goals and resources. They also typically require more data (such as conversion history) to run compared to CPM campaigns, which you can launch without knowing much about previous performance.
Of course, like any metric, your CPM meaning will be clearer with some context. You’re probably wondering: What is a good CPM?
There is no universal “good” CPM for all brands. That’s because CPM varies widely based on your industry, campaign objective, audience, and platform. For example, if your audience skews younger, you’ll likely have a very different TikTok CPM than your Facebook CPM.
That said, there are still some CPM benchmarks to keep in mind on different platforms to help guide your decisions about where you stand. We pulled together the following averages from brands using Triple Whale.
Take a look at the average CPM benchmarks.
These numbers can also vary from campaign to campaign. That’s normal: A “good” CPM depends on your industry, how you’re targeting your audience, seasonality, and the placement of your ads, which we’ll take a closer look at in the next section.
CPM isn’t a fixed rate. Instead, it fluctuates based on a range of factors. Understanding how these factors shape your CPM will help you interpret your own data and set realistic expectations for your ads.
Here are some of the things that affect your CPM:
So what does this all mean for your business? You could have a $2 CPM for one low-demand campaign and a $18 CPM for a high-demand campaign and neither figure would be inherently “bad” or “wrong” — just different.
That said, you may still want to improve your CPM. It ultimately helps lower costs and support your bottom line.
But it’s not just about lowering costs. Improving CPM is about improving the efficiency of each impression.
Here are some of the strategies you can try right now:
CPM alone doesn’t paint a complete picture of your brand’s performance. Instead, it fits into a broader vision of performance when you look at it in relationship with other metrics.
In fact, you can think of CPM as the start of a chain reaction in your metrics.
CPM is what you pay for attention to your ads. Click-through rate is how relevant your ads are. When you look at CPM and CTR together, you can calculate your cost per click, or what you pay for actual interest in your business.
When you look at your CPC and your conversion rate together, you can calculate your cost per acquisition. This number factors heavily into your return on ad spend (ROAS), which is essentially a measure of how efficient your marketing efforts are on a specific platform.
CPM is, clearly, only one small part of this chain reaction. That means a low CPM doesn’t necessarily mean success and a high CPM doesn’t necessarily mean failure. Instead, it’s a starting point that can help you optimize your efforts from the very beginning.
CPM is widely used because of its potential perks, but it’s not without downsides.
Even though CPM marketing can be relatively straightforward, it’s also easy to fall into some common traps. Here are the most frequent CPM mistakes to watch out for.
Wanting to keep your costs low is understandable. But if you cut back so far that it affects the quality of the creative for your campaigns, your ads likely won’t be as effective. It’s important to strike the right balance between optimizing for low CPM and keeping ad quality high.
Similarly, a low CPM might look good on balance sheets, but if your audience quality is low, that money isn’t getting you the reach you’d hoped for. CPM is often lower in broader audiences, which means you could end up with low engagement or traffic from users who won’t turn into customers.
As mentioned above, CPM is a starting point for a chain reaction of other downstream metrics. If you’re not tracking those, too, you’re not getting the full picture of your performance.
It’s tempting to keep CPM low by opting for below-the-fold ad placement or placement on low-viewability (aka low-traffic) websites. But if your ads aren’t seen, it doesn’t matter how low CPM is: You won’t get the brand awareness you’re looking for.
Frequency capping is a way of regulating how many times a user sees your ad. You might think more is always better, but if they see your creative too frequently, they might ignore it or even get frustrated with your brand. That said, low ad frequency might not make them familiar enough with your brand the next time they encounter you. It may take some trial and error to find the perfect balance that also aligns with what you’re hoping your CPM to be.
CPM in advertising — which stands for cost per mille, or the cost per 1,000 impressions — is an effective strategy for increasing awareness and visibility for your brand, especially when you’re hoping your ads reach a large audience.
It’s not only about optimizing for the lowest possible CPM, though. It’s really about making sure the impressions you get work for you.
