I'm sure this has been discussed at length before, but I got a $50 voucher for FB advertising and since I'm new to it, I was wondering what might be the best approach to trying it out. I have an e-commerce site and have already made a FB fan page that's has many posts over a few months, but is only 'liked' so far by my friends. Should I build CPC ads linking directly to my website or is it a better use of money to try to attract more friends to the fan page and go for a sale later? If the latter, should I use CPC or is it worth trying CPM? I'm selling consumer goods in the $300+ range so I'm never expecting a quick sale anyways. Thanks for any advice!
