New on Facebook Ads: Pay only when 100% of an ad is seen

Facebook has recently announced that brands will have the option to pay only when 100% of an ad is seen. 

This is a very good news for advertisers as the concept of viewability  becomes more and more important.

Sometime later this year Facebook will begin letting advertisers only pay for an ad if 100% of it appeared on a person’s screen. But there’s no requirement on how long an ad would need to be in view before an advertiser is charged, according to a Facebook spokesman. The spokesman declined to comment on why Facebook isn’t placing a minimum requirement for how long an ad needs to be appear on screen for the view to count.
