I've been making some decent money online for over a year now, but I haven't really gotten in to CPA yet and I know that is key. Over the past two months I have tried a few different CPA methods, none of them involved locking content, and I've only made about $10. I haven't spent a lot of time on it, but clearly I don't have a great method yet. Here is my question: Should I buy Content Locker Pro and start using content locking methods (will it pay off relatively soon basically) or would I just be better off spending $100-$200 on an adsense site from Flippa? I appreciate any input anyone might have. Thanks!
