the hell is the new algorithm for facebook

i just knew facebook changed his algorithm when it comes to showing news feed, reducing links reach from pages and focusing on "friends posts" am i right ? my facebook page has 12% reach when it comes to links, will this percentage get lower after this update?

Might be, but think on something else like this might help you: http://www.blackhatworld.com/seo/in...-and-facebook-2-hours-day-manual-work.788529/
