all my traffic's been blackhat since I started. nothing white. my epc's dropped too low to tolerate at this point. will adding in quality whitehat traffic get my epc back up? is ppc, email good for this? btw im using email submits. i know a lot of people talk about email subs converting well day 1-2 then dropping, which is exactly what i normally experience with my all blackhat traffic; however they claim they're doing whitehat - is this really true?
