CPM (Cost Per Thousand Impressions): The Price of Visibility
CPM, or cost per thousand impressions, is how display and awareness campaigns are priced. This guide explains when it makes sense.
CPM (cost per thousand impressions) is the price you pay for one thousand ad impressions, or views, regardless of clicks.
What CPM Is
The M in CPM stands for mille, the Latin for thousand. You pay a set rate for every thousand times your ad is shown.
Clicks do not matter to the price, only visibility does.
When to Use CPM
CPM fits awareness goals: brand campaigns, retargeting, and placements where you want broad exposure rather than immediate action.
It is also common on display networks where users are not ready to click yet.
CPM vs. CPC
- CPM pays for impressions, CPC pays for clicks.
- CPM suits top-of-funnel awareness, CPC suits direct response.
- High CTR makes CPM cheap per click in practice.
- Weak creatives waste CPM budget fast.
How to Use It Well
- Pair CPM campaigns with strong, clear creative.
- Track engagement metrics, not just impressions.
- Cap frequency so you are not paying to show the same user repeatedly.
- Compare effective cost per click to your CPC benchmarks.
The campaign: a brand runs a display campaign priced at $5 CPM.
The math: 100,000 impressions cost $500, with no guarantee anyone clicks.
The result: click-through stays low but brand recall climbs for the launch.
The lesson: buy CPM for reach, buy CPC for response.
Quick Tip
Only run CPM when your creative is strong enough to earn the attention you are paying for.
