Facebook now also recommends pages in the news feed, but only if your nonprofit has opted-in to have your page recommended. Until today page recommendations only occurred when individuals liked a page, but now recommendations are also given when individuals like a status update in the news feed. Facebook has not officially announced the new functionality, so it may only be a temporary upgrade and not for all users, but for however long the functionality exists ensuring that your page is optimized for recommendations is a simple way to gain new fans.
