In order to make an extra bit of pocket cash, I've been using PayPerPost on my JDorama review blog. The idea behind PPP is that bloggers sign up and after their blog is approved, they get to choose from a list of advertisers what they want to post about. Each opportunity has different requirements and, as such, pays varying amounts. Once you write your post, you submit it to PPP for approval. After the post is approved, you wait 30 days and payment is sent via PayPal. In the beginning, I thought this was a really awesome service. I could make some (fairly) quick and easy money while blogging. However, after about a month, the opportunities began to dry up. Instead of $10 or $20 opportunities, all that is available nowadays are $5 opportunities asking you to blog about a educational tutoring service. Granted, I've made about $150 in the short time I've been using PPP but it doesn't seem that I'm going to be making much more than that.
If you're looking to make a little bit of money off your blog and you don't mind waiting the 30 days for payment, PPP would be worth a shot. I'm really hoping that things pick up for them and a bigger variety of opportunities become available for bloggers. Otherwise, this service is pretty useless.
