Something I’ve noticed recently when reading my News Feed on Facebook is the fact that they are nesting posts together based on the tool you are using to post. I saw one that had 46 nested posts!!! These two screenshots show that no matter how wonderfully interesting your content is, Facebook wants you to navigate to Facebook itself and post your information, not using a third party tool. This also increases your EdgeRank (your Page’s visibility in the Top News view). The best approach is to manually post unique content.
They don’t like the fact that’ve we’ve been using so many ways to post without actually being on FB. Their board, their rules. Get used to it.
