Frequently asked questions
What is the CPM formula?
CPM = (total cost / impressions) x 1,000. $500 for 150,000 impressions is a CPM of about $3.33.
What does CPM stand for?
Cost per mille - 'mille' is Latin for thousand. So CPM is the cost for every one thousand impressions of your ad.
What is a good CPM?
It varies by platform, audience, and season. Display CPMs can be a few dollars; niche or competitive audiences on social run much higher. Compare like-for-like placements.
When should I use CPM vs CPC?
CPM suits awareness and reach campaigns where impressions matter; CPC suits performance campaigns where you pay only for clicks. Match the metric to your goal.
How can I lower my CPM?
Refine targeting, improve ad relevance and quality, test creatives, avoid over-competitive audiences, and pick less saturated placements or times.
