O que é CPM (Cost Per Mille)?
Definição Rápida
O CPM (Custo Por Mil) é um modelo de preço em publicidade em que os anunciantes pagam por cada 1.000 impressões do seu anúncio, muito utilizado em campanhas de brand awareness.
CPM stands for "Cost Per Mille" (mille is Latin for thousand). It represents how much an advertiser pays for every 1,000 times their ad is displayed. If a campaign has a $10 CPM, the advertiser pays $10 for every 1,000 impressions.
CPM is the standard pricing model for brand awareness campaigns where the goal is visibility rather than direct clicks or conversions. Display advertising, video pre-roll ads, social media reach campaigns, and programmatic advertising typically use CPM pricing.
CPM rates vary dramatically based on the platform, audience, and ad format. Facebook CPMs average $5-15, LinkedIn CPMs are $20-40 (reflecting a more valuable B2B audience), and premium website placements can range from $10-50+. Video ads generally have higher CPMs than static display ads because they're more engaging.
To calculate CPM: (Total Ad Spend / Total Impressions) x 1,000. To estimate campaign cost: (Desired Impressions / 1,000) x CPM Rate. For example, if you want 500,000 impressions at a $10 CPM, the cost would be $5,000.
Por Que é Importante
CPM is essential for planning and evaluating brand awareness campaigns. While CPC and CPA measure direct response, CPM measures how efficiently you're reaching your audience. A lower CPM means you're getting more eyeballs for your budget.
Comparing CPMs across platforms and campaigns helps you allocate your advertising budget more effectively. If LinkedIn has a $30 CPM but reaches your exact B2B decision-makers, it may be more cost-effective than a $5 Facebook CPM that reaches a broader, less relevant audience.
