🧒 Explain Like I'm 5
Think of CPM like hiring a skywriter to write a message in the sky for your neighborhood party. The skywriter charges you based on how many people might see the message from their homes, not on how many actually decide to attend. In digital advertising, CPM works the same way. You pay for every thousand people who might see your ad online, regardless of whether they click on it or buy something. This is a great way for startups to quickly get their brand noticed by many people, like sending up a big, bright signal in the sky to attract attention.
📚 Technical Definition
Definition
CPM stands for Cost Per Thousand Impressions, a key metric in digital advertising that indicates the cost of 1,000 ad views or 'impressions'. It is a pricing model where advertisers pay for the potential exposure of their ads to a broad audience, without guaranteeing any engagement.Key Characteristics
- Measurement of Reach: CPM is all about potential reach, focusing on how many times an ad is shown.
- Cost Efficiency: Often a cost-effective strategy for increasing brand awareness on a large scale.
- Non-Engagement Focused: Advertisers pay based on impressions rather than clicks or conversions.
- Common in Display Advertising: Widely used in campaigns where the primary goal is visibility.
- Pricing Variation: Costs vary depending on factors like platform, audience targeting, and competition.
