Facebook video ad and post plays have increased nearly eightfold year-on-year just at the time that the social media giant launches auto-play adverts to selected partners. Adobe's Social Media Intelligence Report concluded this has led to a 2% increase in revenue per visit (RPV) while RPV from Twitter and Tumblr declined by 23% and 36% year-on-year. The research showed that text-only posts were declining in engagement compared to posts with links rising by 167%, in terms of likes, comments and shares. The biggest day for engagement with posts is, unsurprisingly, Friday.
