What is Pay Per Impression?
‘Pay Per Impression’ refers to an online advertising model that lets the advertisers pay when their advertisement is seen by an online visitor. Usually, as the number of visitors would be huge, the prices are set on a scale of per thousand impressions, usually known as ‘cost per thousand impressions’ or CPM.
CPM can be used to understand how effective an advertisement is. The term ‘impression’ refers to someone viewing the page or advertisement once. Hence, if the same individual views the same page again, it will be counted as a different ad view.
The PPI model of advertising is generally used in cases where the advertiser wants to create interest in the minds of the targeted audience. It can also be used in cases where the intent of the advertiser is to create brand awareness or send a social message.
