CPM stands for cost per thousand impressions. It is a common metric used in online advertising to measure the effectiveness of an ad campaign.
CPM is calculated by dividing the total cost of a campaign by the number of impressions delivered. It is a useful tool for gauging how much an advertiser is spending to reach a particular Target audience.
CPM can be a useful metric for evaluating an online advertising campaign’s effectiveness, but it should not be the only factor that determines whether or not an ad campaign is successful. Other factors that should be considered include the size of the Target audience, the frequency of the ads, and the cost of running ads.
