Quality over quantity—Facebook believes this is the key to happy fans, and its team recently updated the news feed ranking algorithm to reflect this.
But what does that mean? It means Facebook determines what is “high quality content” and prioritizes what appears in your fans’ news feed. This means only 20 percent of the posts from pages you like actually appear in your news feed. Lesser quality content is pushed out, never to be seen again... unless fans visit the actual page and scroll through the timeline.
