What Is CPM?

CPM stands for Cost Per Mille, which is also known as Cost Per Thousand. It is the marketing term that is used to denote the price of 1,000 advertisement impressions on one webpage. For example, if the website publisher charges $2 CPM, then the advertiser has to pay $2 for every 1,000 impressions of its ad.

The CPM Formula

For using it, you just have to divide the cost by the no. of impressions divided by a thousand.
CPM = 1000 * cost / impressions

Types of CPM


Viewable CPM relates to how much an advertiser is prepared to pay for actual views. It is not calculated after the campaign has been rolled out. In fact, it helps to set the minimum bid amount for display ads. If the reader doesn't scroll down to see it, then the advertiser does not pay for the impression. Google mentioned that at least 50 percent of the content must appear for one second or more.


Effective Cost Per Mille is not just enough that the ad was placed on the page or it was viewed. The revenue will generate when the customer actually click on the ad. You can calculate eCPM by dividing the total revenue from clicks by the total number of impressions.

Cost Per Completed View is specifically relevant to the video ads. You will be paid only when the entire video has been seen by the view. If he dropped it halfway then, it will not be considered as viewed. Advertisers define a specific performance milestone, like 5 seconds or 10 seconds in a video. If it crosses the milestone, the ad is considered as viewed. 

Benefits of CPM

  • Brand Building
  • Target Audience Identification
  • Strategic Reinvestment

CTR Impacts Ad Rank

CTR also subscribes to your ad rank in the search engines. Ad rank defines the position of your ad on the search results page. 

The top position does not go to the highest bidder. It persists to the advertiser with the highest Ad Rank. If you have a lot of ads with low CTR, Google will consider that any new ads to your google ads account are also going to have a low CTR, that may rank them below on the page. A poor CTR  may lead to a low position, it doesn't matter how much you bid.

CTR Impacts Quality Score

Quality score is another factor as it relates to keywords, landing pages, and ad copy. If the ads and landing pages are more relevant to the user, there will be higher chances to see high-quality scores. 
On the other hand, good cost-through-rate helps you earn higher quality scores.

Let's say if you have a high CTR rate, but an abysmal conversion rate. So then, there might be a problem with your landing page or might be something wrong if you are getting a ton of clicks
 and no results from them.
