What is CPM in Media Buying?
CPM, or Cost Per Mille, measures the cost of one thousand ad impressions. It’s a standard metric used to quantify the expense of displaying an advertisement to thousands of potential customers. Depending on the application, CPM is an important in media buying as it helps advertisers understand the cost-effectiveness of various advertising platforms and campaigns.
What is a Good CPM?
Determining a “good” CPM depends heavily on the medium of advertisement and the specificity of the target audience. Generally, broader targets tend to have lower CPMs due to a wider reach with less specific targeting criteria. For example, a campaign targeting anyone aged 18 will likely cost less than one targeting women aged 25-54, who represent a more defined and possibly more lucrative demographic.
There’s no universally “correct” CPM; its value depends on the specific goals of the campaign, the target audience, and the advertising mediums selected.
Variability of CPM
CPM’s importance varies by the advertising medium:
- Digital Campaigns (e.g., Google Ads):
In highly targeted digital campaigns, such as those on Google Ads for local searches, CPM might not be the primary focus. Here, other metrics like cost-per-click (CPC) or conversion rates can be more relevant. Highly specific targeting can lead to higher CPMs due to limited audience size. - Traditional Media (e.g., Billboards, Broadcast TV):
For broader branding efforts through billboards or broadcast television, achieving a lower CPM can be more relevant. These mediums typically aim to maximize exposure, where a wide audience is targeted, possibly lowering the CPM.
Market Dynamics and Inventory Availability
The availability of ad inventory and market demand also significantly influence CPM rates. Higher demand for advertising space in a particular medium can drive up costs, affecting CPM. Conversely, having plenty of available space may reduce the cost.
Tracking CPM
If CPM is a key performance indicator (KPI) for your campaign, you may want to track it over time. This monitoring helps gauge market behavior, shifts in audience dynamics, and the cost-effectiveness of reaching potential customers.
