What is Cost Per Mille (CPM)?
Cost Per Mille (CPM), or cost per thousand impressions, is a key advertising metric that quantifies the expense of delivering 1,000 ad impressions to users. In contrast to CPC, which incurs costs for each click, or CPA, which charges for each acquisition, CPM operates on a different model. It bills advertisers according to the frequency of ad displays, irrespective of how users interact with the ad.
CPM = Total Campaign Spend/Total Impressions×1000
Example
- Total campaign spend = $500
- Total impressions = 100,000
CPM = 500/100,000×1000
= 0.005×1000
= 5
So your CPM = $5. ✅
That means it costs you $5 for every 1,000 views of your ad.
Why CPM Matters
Brand Awareness Driver:
CPM holds significant value for campaigns focused on enhancing visibility, awareness, and reach, rather than solely driving direct conversions.
Budget Forecasting:
Understanding CPM enables companies to predict expenses for effectively engaging extensive audiences on a grand scale.
Channel Comparison:
CPM enables marketers to evaluate the effectiveness of reach across various platforms such as Google Display Network, Facebook Ads, YouTube, and programmatic ads.
Top-of-Funnel Impact:
In awareness campaigns, CPM offers a straightforward metric for evaluating cost efficiency during the impression phase, prior to any clicks or conversions occurring.
CPM vs. Other Metrics
- CPC (Cost Per Click): Emphasizes interaction (clicks), whereas CPM prioritizes exposure (impressions).
- CPA (Cost Per Acquisition): Calculates the cost for each real customer, whereas CPM focuses solely on visibility.
- CTR (Click-Through Rate): This highlights the effectiveness of impressions in generating clicks, in contrast to CPM, which merely tracks the number of times an ad is viewed.
