Cost per engagement (CPE) is an advertising pricing model in which digital marketing teams and advertisers only pay for ads when users interact with their campaign in some way. The term engagement includes any interaction a consumer has with the advertisement, such as pausing or muting a video, playing a mini-g**e, taking a survey, signing up for a free trial, reviewing a product or sharing a post on social media. Advertisers can choose between models that charge for every engagement which could include simply closing the ad or for meaningful engagements such as clicking through to the website and positively engaging with the ad.
