Social-media analytics company Socialbakers recently conducted a study concluding that photos perform most poorly among any other update on Facebook. Facebook’s latest algorithm update is likely in response to two things: perhaps a back-handed response to page owners trying to game the system by constantly posting photos, or moreso a push aligning with Facebook’s shift toward video in recent months.
As noted by Business Insider, “The Socialbakers data, which covered 4,445 brand pages and more than 670,000 posts between October 2014 and February 2015, shows that video is now the most effective way to reach users in Facebook’s News Feed, driving more than twice as much reach as photo posts.”
