What is a CPM?
Are you unfamiliar with what a CPM (cost per mille) metric is in advertising and paid media? Imagine you're throwing a birthday party and you want to invite all of your friends. You could send out invitations by mail and postal service, right? Well, CPM (cost per mille) in paid media advertising is a bit like the cost of postage stamps.
Each stamp lets you send one invitation. In advertising, CPM is the cost to show your ad to one thousand people ("M" stands for the Roman numeral for thousand).
The more invitations you send, the more stamps you need. Similarly, the more people you want to reach with your ad, the higher the CPM cost will be.
Some stamps are more expensive than others. If you want to send a fancy invitation or one that goes further away, you might need a pricier stamp. Likewise, some advertising platforms or placements are more expensive than others, leading to a higher CPM.
So, just like you pay for each stamp to send out your invitations, advertisers pay a CPM fee for every thousand people they reach with their ads.
This is the impact of the CPM on impressions for a $10,000 ad campaign.
Tips for Using CPM
Are you still wondering how to use CPM in your campaign planning or reporting on it as a metric to stakeholders? Here are a few tips on how to use it.
Think of CPM like paying for eyeballs: It's not about clicks or actions, but simply about how many times your ad is seen. Imagine paying to put up a billboard on a busy highway - you're paying for the thousands of drivers who will see it, even if they don't stop to buy your product right away.
"M" is for "Mille" (Thousand): The "M" in CPM stands for the Roman numeral for thousand. So, a CPM of $5 means you pay $5 for every 1,000 people who see your ad.
CPM is about Awareness, not Direct Sales: It's great for building brand recognition or launching a new product. You're casting a wide net to get your message out there, hoping that some of those viewers will remember you later and become customers. It's less about immediate results and more about long-term impact.
At the end of the day, CPM is about ensuring you are cost-effectively reaching the largest target audience possible. It is both a quality check and a way to optimize costs. You will find some platforms are more expensive than others and some audiences that are less active online or more difficult to reach are also more expensive. Be sure to test and monitor your CPMs to find the most cost-effective media strategies for your brand.
High or Low CPM: What Does it Mean?
High CPM:
What it means: You're paying a premium to reach your audience. This could be due to factors like high competition for ad space, targeting a niche audience, or using premium ad placements.
Actionable steps:
Refine your targeting: Ensure you're reaching the most relevant audience possible. Broad targeting can lead to higher CPMs as you compete with more advertisers.
Test different ad placements: Some placements naturally command higher CPMs. Experiment with less expensive options to see if they deliver comparable results.
Optimize your ad creative: Compelling ads can improve engagement and click-through rates, potentially lowering your CPM over time.
Consider alternative platforms: If CPMs are consistently high on one platform, explore other options with potentially lower costs.
Re-evaluate your campaign goals: If brand awareness is the primary objective, a high CPM might be acceptable. However, if conversions are the goal, you might need to adjust your strategy or budget.
Low CPM:
What it means: You're reaching your audience at a relatively low cost. This could indicate less competition for ad space, a broad target audience, or the use of less premium ad placements.
Actionable steps:
Analyze audience quality: A low CPM might indicate you're reaching a less engaged or less relevant audience. Monitor conversion rates and other key metrics to ensure you're getting value.
Experiment with more premium placements: If your campaign is performing well, consider testing more prominent placements to potentially increase visibility and results.
Expand your targeting: A low CPM could mean you're missing out on potential customers. Carefully broaden your targeting to reach a larger audience.
Increase your budget: If you're seeing strong results at a low CPM, consider increasing your ad spend to reach even more people and maximize your ROI.
Remember, CPM is just one metric. Always analyze it in conjunction with other key performance indicators (KPIs) like click-through rate (CTR), conversion rate, and return on ad spend (ROAS) to get a complete picture of your campaign's effectiveness.
