I can send decent traffic towards Zip Submit offers. For instance, for an iPad Zip Submit, I can do about 3000 clicks a day from people actually looking to win an iPad for free. All legitimate hits. All here in the States. 1 in 7, leave their Zip. EPC of about 20 cents on $1.50 payout. Problems are the same - scrubbed leads, abrupt requests to halt campaigns. I want to be able to maximize my profits. What should I do? Thanks.
