So I've been trying out Facebook with some lead gen offers and would also like to try different ppc networks (probably adcenter). My question is that if I'm gonna direct link how will I track keywords to see which ones are converting? Also having a hard time coming up with cheap longtail keywords, it seems like if I get one that is cheap enough it won't bring me barely any traffic at all. Especially if I'm targeting a certain demo, it will narrow down the traffic even more. Any advice on the two problems would be great. Thanks
