"You just need to know what products to sell and target the right audience" I think you say the best solution but there's one thing that's not controllable, the validation by the advertisers....who sometimes do not validate all lead
I started a niche affiliate site a month ago and yesterday I got 2 sales which brings me $0.58 Still feel happy because I know this way of making money truly WORKS!
Choosing products that are converting well is the key. I used to sell software products via Amazon, but I failed - guess why.
