FAQ

Get answers to common questions about Lessie AI.

What is CPM?

CPM stands for Cost Per Mille (cost per thousand impressions). It is a standard advertising metric that measures the cost of 1,000 ad impressions. CPM = (Total Ad Spend / Total Impressions) x 1,000.

How do I calculate CPM?

Divide your total ad spend by the number of impressions, then multiply by 1,000. For example, if you spent $500 for 100,000 impressions, your CPM is ($500 / 100,000) x 1,000 = $5.00.

What is a good CPM?

A good CPM varies by platform and industry. Social media ads typically range from $5-$15, display ads $2-$10, video ads $10-$30, and search ads $15-$40. Lower CPM means more cost-effective reach.

What is the difference between CPM and CPC?

CPM (Cost Per Mille) charges per 1,000 impressions regardless of clicks, while CPC (Cost Per Click) charges only when someone clicks your ad. CPM is better for brand awareness campaigns, CPC for direct response.

Is this CPM calculator free?
