Cost Per Mille (CPM) is a financial metric that measures the cost of reaching 1,000 people with an online ad. It is commonly used in digital advertising, particularly in display and social media advertising.
CPM is calculated by dividing the cost of an ad campaign by the number of impressions (views) it generates, and multiplying that number by 1,000.
For example, if an ad campaign costs $100 and generates 10,000 impressions, the CPM would be $10. CPM is an important metric for businesses, as it helps them to understand the cost of reaching a specific audience with their ads and to optimize their ad spend.
By decreasing their CPM, businesses can improve their ROI and increase the profitability of their ad campaigns.
