In this case, 2.2% viral reach refers to the percentage of people who see the video via viral means, rather than directly via Facebook. The “viral” classification is limited to users who actually interact with video content following another user’s comment, share, or like. The data also excludes paid reach from its analysis.
Socialbakers found that Facebook videos also sport a higher engagement rate (0.22% vs. 0.1%), which the company suggests could be due to the ability to play a Facebook video directly from the mobile newsfeed (as mobiles become an increasingly important device for Facebook access.)
Interestingly, both methods of posting videos generated similar types of interactions from fans, with likes accounting for approximately three-quarters of the interactions, and shares more common than comments.
Socialbakers notes that there are pros and cons to both methods of sharing videos on Facebook. For example, fans can be tagged in Facebook videos, but YouTube is the most popular video-sharing site, and Facebook videos can’t be shared outside the network. (For context, Google Sites, primarily powered by YouTube, boasted about 150 million unique video viewers in January, compared to roughly 57 million for Facebook, per comScore data.)
