targeted traffic: Males in the age category 18/24..
They have clicked something that they want to have, most likely a download.
Make your ad appear like a Download button "Download your file here"
Then send this traffic to a Download CPA offer that will make you 1 dollar + per install..
Then for US traffic you will only need 4 conversions out of a thousand people to call it even.
If you play with big numbers it can be very profitable..
For example.. you pay $4 dollars for 1000 US views. Select a US download offer from your cpa network that pays you $1,10
Let's say your clickthrough rate on ****** is 10% since your ad is a download button the user will be a bit confused thinking they have reached their desired location and click your ad without thinking too much.
Lets say the conversion rate of the actual offer from your network is 4%.
Your ROI would be 10%. you would make $0,40 cents for every 4 dollars invested.
Again, this can be profitable but you need to play with large numbers and test what works.
the more you can bump up your CTR on the ****** page, the better you will do
Hope this will help
