How The New Facebook Search Is Different & Unique From Google Search
With a typical Google search, the objects we search for are Web pages, with the connections (or graph) that help determine the pages that rise to the top primarily being links from across the Web. Links, simple form, are like votes, helping Google decide which are the most popular pages to show for a particular topic.
With Facebook Graph Search, the objects we search for aren’t Web pages but instead virtual representations of real world objects: people, places, and things. The connections are primarily Facebook Likes. Did such-and-such a person like a particular photo? A particular doctor? A particular restaurant? Those likes are the ties that bind the information in Facebook together.
If you want your Facebook fan page to be more visible then you need to:
a. more connected to other pages and groups through Likes
b. received more comments on your postings (called engagement in fb vocab)
c. have more of your keywords used in your postings, and the comments you post to others’ posts.
