Feed section of the Facebook social network is a continuous source of information, some of which is directly of interest for users but often messages and posts that are of no interest to them are still displayed in their News Feed. About 1,500 daily postings go through the news section of a user, but only 20% of them remain after a filtering process, according to a Facebook software engineer.
Facebook specialists, quoted by Mashable.com explained during an event at the company headquarters in Menlo Park, California, the algorithm by which only certain posts appear in each user’s News Feed.
The selection process follows an algorithm based on thousands of “signals” to assign each post a certain score. Depending on its score, each post is placed in a certain position in the News Feed. The posting with the highest score is ranked first in the News Feed section.
Scores are awarded based on many factors including the relationships the users have with people posting and the number of comments, likes, distribution of posts between the user and those persons.
Previously, whenever a user updated their Facebook page by refreshing, new posts automatically appeared on top positions even if they had lower scores than the previous posts. Now the algorithm is changed, allowing older posts that were not visible to the user to remain among the leading position of the news section.
“Our main goal is really to make the best personalized newspaper for our users.” To put “the best stories at the top where you’re most likely able to engage with them,” said Lars Backstrom, a news feed engineering manager.
“It’s just another step to make the site more useful. Users aren’t going to go, ‘Wow, they’re bumping posts.’ But the fact that they’re doing it is going to make the site more useful. That’s Facebook’s game now,” said Nate Elliott, vice president and principal analyst with Forrester Research.
