I have heard comments that it is not very accurate. By accurate I mean your site is not necessarily out to other pages related to the theme of your business, and if this is true, not many people will be interested in your page. I read this in a couple reviews somewhere in the web.
My final decision was not to use it in my FB pages. I think it also depends on the type of business you promote. Sometimes it could be more useful than others. I clarify that I’ve never used it.
