Did you set up a follow-up sequence program for those who opted-in for your offers?
Sales are very dependent on your email follow-up sequences on your autoresponders as not many visitors would subscribe/buy your product immediately after seeing your advertisement. Normally it would take 3-5 exposures to the ad before getting a sale.
Oh no! That's a huge mistake Joseph. With any type of traffic, especially solo ads, you MUST capture email leads.
You are wasting your money and I find it strange that the seller sent you the traffic to be honest, i would have denied and told you to build a capture page and get leads.
As it stands, most likely you won't be seeing sales unless the clickbank product you were promoting is emailing for you (sounds like they wont be).
I would not pay for anymore traffic until you make a capture page and a followup sequence my friend.
The above suggestions are right on... you have to have a follow campaign and be capturing emails. DM me if you need help with that.
