Even though most brands still can't run ads on Instagram, they are highly active on the social network. According to AdWeek and data from Shareablee, "Facebook garnered 2.5 million brand posts, a year-over-growth of 22 percent" while "Instagram had 493,000 of such posts, a 49 percent year-over-year jump." But Instagram is beating Facebook in total actions per post.
According to the Shareablee data, Facebook sees, on average, 2,936 actions per post. Instagram on the other hand saw an average of 6,932 actions per post. Instagram users are much more engaged than Facebook's users, a positive sign for the future monetization of the platform. Which, in the end, is good news for Facebook because it owns Instagram.
