Cost per Engagement

Explicación leída en un Paper de Forrester sobre Publicidad Online:

• CPE (cost per engagement) is emerging as a metric. CPE is a newer ad model whereby advertising is offered free, with advertisers paying only when viewers actually engage with the ad itself (thus differing from CPA, which looks at consumer activity post exposure). “Engagement” can be defined in a number of ways, such as completing a survey within the ad, entering a competition, or watching a certain amount of video. Online video ad provider VideoEgg pioneered this payment system in 2008.11 This method is seen to push back more responsibility for ad performance onto the ad creative than other methods such as CPC, which were thought to place the bulk of the burden of performance onto the publisher. It is also a way of measuring interaction with newer types of creative — such as video ads or ads with product comparison tools within them — that may drive significant interaction but not actually click-throughs. However, as “engagement” means something different for every marketer, such metrics are not comparable across campaigns even for the same marketer, limiting their value.

Y la Wikipedia:

Cost Per Engagement (CPE) is an online advertising pricing structure introduced into the market in 2008.[1]

Differing from cost per impression or click through rate models, a Cost Per Engagement model means advertising impressions are free and advertisers pay only when a user engages with their ad unit. Engagement is defined as a user interacting with an ad in any number of ways, including playing a game, taking a poll, rolling over an ad unit for a specified amount of time or taking a product tour.[2]

Cost Per Engagement brings a measure of performance to online advertising. Ads are served for free, and advertisers pay only when a user engages with their brand content. The approach has given advertisers a choice between quantity and quality.[3]
