vCE® (Viewable Cost per Engagement) is a metric used in digital advertising to measure the effectiveness of an ad campaign by tracking the number of viewable impressions that result in an engagement, such as a click or video view. This metric takes into account not only the number of impressions, but also the quality of those impressions, ensuring that advertisers are only paying for ads that are actually seen and engaged with by their target audience. vCE® provides a more accurate and transparent way to evaluate the success of digital advertising, allowing advertisers to optimize their campaigns for maximum impact and return on investment.
