Facebook on Friday announced that is has updated its News Feed ranking algorithm to feature more "high quality" content from Pages.

"Every day people see content from millions of Pages on Facebook in their News Feeds," Facebook software engineer Varun Kacholia wrote in a blog post. "Our goal is to show the right content to the right people at the right time so they don't miss the stories that are important to them. As part of that we want to make sure that the best quality content is being produced, surfaced and shared."

The update, rolling out to all Facebook users in the next few weeks, is intended to "ensure that the organic content people see from Pages they are connected to is the most interesting to them," Kacholia added.

The updated system uses more than 1,000 different factors — such as how often content from a Page is hidden and how complete the Page's profile is — to determine whether a post is high quality. The social network tested the new algorithm on "small segment" of users and found that they interacted more with content (by liking, commenting, and sharing it) as well as hid fewer stories overall.

Even so, the social network acknowledged that the system is still new and won't be perfect, meaning you may still see Page posts in your News Feed that you don't care about.

"Coming up with an algorithm to detect this is complex, and we will continue to refine it as we get more feedback," Kacholia wrote.

Meanwhile, the update comes after Facebook earlier this month tweaked its News Feed ranking algorithm to display older stories you might have missed that are getting a lot of likes and comments. Thanks to that change, stories you don't scroll down far enough to see on your News Feed will now reappear near the top of it the next time you visit Facebook, if the social network thinks you might find them interesting.
