The company is considering live videos as a new content type different from normal videos, and learning how to rank them for people in news feed.

"As a first step, we are making a small update to News Feed so that Facebook live videos are more likely to appear higher in News Feed when those videos are actually live, compared to after they are no longer live," wrote Vibhi Kant, product manager and Jie Xu, software engineer at Facebook in a blog post.

"People spend more than 3x more time watching a Facebook live video on average compared to a video that's no longer live. This is because Facebook live videos are more interesting in the moment than after the fact," they wrote.

Facebook's live video feature allows users to broadcast live video from their smartphones. News Feed is made up of posts from the friends and pages you have connected to. These posts can be status updates, photos, videos, links and now, Facebook live videos.

We rolled out Facebook live on iOS in December and last week, we began rolling it out on Android in the US. Over the last three months, Facebook Live video has become more and more popular and more and more people and pages are creating and watching live videos," the Facebook officials posted."

As with any new type of content in News Feed, we are learning what signals help us show you the most relevant Facebook live videos for you personally," they added.

For example, a few years ago when more people began sharing and watching video on Facebook, the company listened to feedback to learn what signals helped them show people more of the videos they want to see and fewer of the videos they don't.
