Hi everyone, I'm posting my case study on a Email/Zip Submit campaign. (Free Sample Products) Hopefully, I can get some insight on what I'm doing wrong and how to make it profitable. July 4 Spent: $6.16 Earned: $4.50 (5 conversions) Net: -$1.66 loss Results 2,802 Imp 88 clicks Avg CPC: $0.07 CTR: 3.14% I am doing sub Id Tracking, but I dont know how to block bad Sub Ids. I watched a video on Youtube and it said to contact 7search to set up sub Id blocking. I emailed them and they didnt seem to know what I was talking about because sub ID blocking isnt activated in my 7search account. Maybe I'm overlooking something or just plain dont no what I'm doing. Any help would be appreciated.
