What is CPM? CPM vs RPM

CPM or cost per mile is a cost that an advertiser will pay to run their brand or product awareness campaign.

CPM campaigns are the default campaigns that are supported by all advertising brokers in the online advertising industry.

The process of creating a CPM-based campaign includes the advertiser creating an ad copy for the ad and deciding the daily budget that the advertiser is willing to spend on the ad campaign. The budget is the total amount of money that the advertiser wants to spend. CPM vs RPM

After the ad campaign has been running for some time, the CPM is calculated by dividing the amount of money in the campaign by the number of impressions delivered for the ad and then dividing that number by 1000.

It is worth mentioning here that when launching a campaign based on CPM, the CPM is high but as artificial intelligence gets to know more about the target audience, the campaign is automatically optimized. This optimization results in lower CPM rates after the campaign has run for a few days.

What is RPM?

RPMs are known as revenue per mile. This indicates the amount of money a publisher will make after displaying 1000 impressions on their online property. CPM vs RPM

RPM is calculated by dividing the amount of money earned by the publisher by the number of Advertising Impressions delivered by him. As with CPM, here too the RPM is optimized once it has been running for a few days. Artificial intelligence technology identifies the audience’s interest in the publisher’s web property and then delivers matching, interest-based ads to the audience.

Since the publisher has no control over what type of ads will be served on its web property, it is possible that it is running other types of ad campaigns.

Main differences between CPM and RPM

CPM is from the advertiser’s perspective, while RPM is from the publisher’s perspective.
CPM is the cost that an advertiser will pay for having served 1000 impressions for their ad. RPM is the amount of money a publisher will make once 1000 impressions have been served on their property. CPM vs RPM
The CPM metric is used to compare the performance of two or more ad campaigns by an advertiser. The RPM metric is used to compare the performance of two or more ad networks of a publisher.
In addition to CPM, the other types of ad campaigns available to an advertiser include CPC, CPI, and CPA with the option to start any campaign they want. Similarly, for a publisher, the available campaigns are CPC, CPI, and CPA with no option to choose between them.
The advertiser has the option to change their ad campaign based on the marketing objective. The publisher does not have much control over the advertising campaign that will run on his property. The best thing an editor can do is optimize ad placement so that more people can see and click on the ads.

Final Thought

CPM and RPM are metrics for 1000 ad impressions. While CPM is relevant to an advertiser, RPM is relevant to a publisher.

If you are an advertiser, you should focus on optimizing your ad campaigns based on CPM, and if you are a publisher, you should focus on optimizing your ad placements based on RPM.
