Last week could you read about Google’s new project Bulletin that will act to promote local news and this week is it Facebook that announces that they will tweak their algorithm in order to display more local news. 
Facebook explains how they will find local news: We identify local publishers as those whose links are clicked on by readers in a tight geographic area. If a story is from a publisher in your area, and you either follow the publisher’s Page or your friend shares a story from that outlet, it might show up higher in News Feed.
