I've been playing around a bit with some new Pay Per Call offers and finding out what I could be profitable with. I tested it out over the last week and it was averaging about a 20% ROI. Today I decided to spend a bit more and am currently seeing about a 85% ROI. Spent $55 and have made $45 profit. Not too much in the grand scheme of things but it is easy income. Always be sure to test an offer out and then scale it when you can be sure it's going to produce profit. 20% ROI isn't a ton but if you can find something to give you 20% over and over again...I'll take that every day of the week.
