What is CPM (Cost Per Mille)?

Cost Per Mille (CPM) is one of the metrics commonly used to assess how successful online advertising is.

The term "Mille" comes from Latin and means a thousand. Therefore, this metric is used to measure the cost for every 1,000 impressions.

When engaging in online advertising and using this metric, advertisers incur costs for every thousand impressions, regardless of the effectiveness of the ad performance. As a result, businesses aiming to boost their brand awareness often maximize this metric.

Understanding how to calculate CPM can be highly beneficial, especially as a business practitioner. If you're curious and want to learn how to calculate CPM, read the article below.

Impression in Digital Advertising

In the context of online advertising, an impression refers to the number of times an ad is displayed on the screen of the target user. 

In other words, each time an ad appears on a web page used by a user, that appearance is counted as an impression.

Although the impression metric cannot provide accurate information about user interaction, it remains effective in assessing how successful a digital campaign is in reaching the target audience.

How CPM Works

Typically, CPM (Cost Per Mille) sets the cost for every 1,000 ad impressions. In this model, advertisers and publishers agree on the cost that the advertiser will pay each time their ad is shown a thousand times.

After the agreed-upon ad cost is set, the ad is then placed on various platforms, such as websites, social media, blogs, and more. When users access pages that display the ad, the ad impressions are counted.

For example, if the cost per 1,000 impressions is set at Rp200,000, and your ad receives 5,000 impressions, you would need to pay Rp1,000,000.
