I am looking for an analytics tool à la Google keyword but for Facebook.
I'd like to find info about how many people search for X and Y in Facebook search field.
Is there anything like Google keyword available for Facebook ?
The best you can get is look through blog posts, such as "2010 Memology: Top Status Trends of the Year" but that doesn't give you nearly the power you're looking for.
Facebook used to have a tool called "Lexicon" but they took it down, probably when they realized just how valuable their data is! Too bad, because I wish I could use that too... https://www.facebook.com/lexicon/.
