Are the fan pages purely business related or some fun ones too? So how about you suggesting some 'catchy names" so that I can garner lots of likes?
As for me, I have 5 of them, with lots of fans but beware guys, facebook traffic are difficult to convert. Majority of them are not 'buying' traffic. So I have moved my target little away from it.
I have too many to count and they are all for business. I also have several facebook accounts each with many fanpages. The best way to rank your fanpages for the search engines are to pick keywords that have little competition and some degree of search. It absolutely works, so your options are limitless. If you need some help understanding search vs. competition, just pm me and I'll explain further. I hope this helps
