Im going to be running a facebook ads promo in a few days, but im just wondering how i can build a list with the people who like my page? because im assuming you cant put a "popup" opt in box on your facebook profile right? i have a iframes app installed with a opt in page, but i dont know whether i'll get clicks on it or not. how else can i build my list with my facebook page? is it just a case of writing posts with my blog articles attached in which people will click onto my blog site and hopefully opt-in? im giving out a free report by the way.
