Key Takeaways


  1. Definition: Cost Per Thousand (CPM) is an advertising metric that represents the cost an advertiser pays for one thousand views or clicks of an advertisement.
  2. Usage: CPM is commonly used in digital marketing where large volumes of impressions are common. It provides an estimate of the cost effectiveness and efficiency of a digital advertising campaign.

The business/finance term, Cost Per Thousand (CPM), is crucial as it measures and tracks marketing efficiency.

It becomes particularly crucial in the digital marketing space where they can analyze and optimize their ad costs by experimenting with different types of content, platforms, or targeting strategies. By measuring a campaign’s CPM, businesses can determine if their marketing investment is delivering a satisfactory return, or if tweaks should be implemented to boost efficiency and cost-effectiveness. In summary, CPM acts as a benchmark that aids in effective decision-making, resource allocation and strategy development in marketing.


1. Advertising Campaign: A company decides to run an online advertising campaign. The online platform charges them $2 CPM. This means that for every thousand impressions (times their ad is shown), they will be charged $2. If their ad is shown 1,000,000 times, it will cost them $2000.2. Publishing Industry: A magazine publisher uses CPM to price its ad space to clients. For example, if the magazine has a circulation of 100,000 and charges a CPM of $10, then an advertiser would pay $1,000 for a page that is seen by that circulation.3. Sponsored Content: A website enters into a partnership with a blogger to promote a sponsored article on its homepage. The website owner charges the blogger a CPM of $5. If 10,000 visitors visit the homepage, the blogger is billed $50 for the exposure. If the number of visitors doubles, the cost also doubles due to the CPM model.
