So to determine if any given Page post shows up in the news feed, Facebook looks at four main factors:
1. If you interacted with an author’s posts before. If you Like every post by a Page that Facebook shows you, it will show you more from that Page.
2. Other people’s reactions to a specific post. If everyone else Facebook shows a post to ignores it or complains, it’s less likely to show you that post.
3. Your interaction with posts of the same type in the past. If you always Like photos, there’s a better chance you’ll see a photo posted by a Page.
4. If that specific post has received complaints for other users who have seen it, or the Page who posted it has received of lots complaints in the past, you’ll be less likely to see that post. This factor became a lot more prevalent starting in September 2012.
