Facebook announced it now delivers 1 billion video views per day, and it's recommending additional videos after the viewer has seen one.
Facebook is also letting marketers include a “call-to-action” link at the end of the video that viewers can click.
And if that wasn't enough to make you consider moving your videos to Facebook, consider this: When Beyonce posted a video last week to both Facebook and YouTube, she got 2.4 million views on Facebook in the first 4 hours. On YouTube, she only got a few thousand views during that same time.
So why is Facebook doing so well in video? Because viewers have a very easy way to share videos with their Facebook friends. In YouTube, there's no equivalent option for sharing.
