**CPM** stands for **Cost Per Thousand** (where "M" represents the Latin word "mille," meaning thousands). It's a marketing term used to denote the price of **1,000 advertisement impressions** on a web page. Let me break it down for you:
1. **Impressions**: An impression counts the number of times an ad is displayed on a site. It doesn't measure whether an ad was clicked on; it simply tracks how many times it was viewed.
2. **CPM Calculation**: Advertisers pay website owners a set fee for every **1,000 impressions** of an ad. For example, if a website publisher charges a **$2 CPM**, the advertiser pays $2 for every 1,000 views of their ad.
3. **Efficiency Measurement**: CPM helps companies measure how efficient their advertising is by revealing how much money they pay for a single click on a website ad. However, keep in mind that CPM doesn't directly measure clicks; it focuses on impressions.
4. **Comparison to Other Metrics**:
- **Cost Per Click (CPC)**: This metric calculates the cost an advertiser pays for each click on their ad.
- **Cost Per Acquisition (CPA)**: CPA measures the cost of acquiring a customer (e.g., making a sale or getting a lead).
5. **Success Evaluation**: Advertisers often assess the success of a CPM campaign by its **Click-Through Rate (CTR)**. CTR represents the percentage of people who saw the ad and clicked on it. However, CTR alone doesn't capture the full impact, as an ad that viewers see but don't click can still have an effect.
In summary, CPM provides insights into how much advertisers pay for exposure, but it's essential to consider other metrics alongside it to evaluate overall campaign effectiveness¹²³.
