Brian wrote an extensive list of pay per review, pay per post or get paid to review services that connects bloggers and advertisers.
Pay per review services nowadays are one of the most chosen among advertisers, because they can get a good permanently link placement on others blogs that looks natural. On the bloggers side, they generate money while doing one of their passion .. POSTING!
I'm new to this service, in fact I haven't got any dime out of this business .. some of my reviews are in pending status, some are approved, but I have to wait for a few days to receive the money.
The first place on the list is blogsvertise.com, which I joined a week ago and had finished my first 4 tasks for around $24.
The second place is, payperpost.com, I haven't joined this service because of a paypal issue.
And the third one is Reviewme.com, I heard they pays well .. up to $200 per review .. but I haven't got one. For me $10 per review is a quite good earning, it will cover my everyday needs. But who knows if I could get as high as $50 per review?
The complete list is here, check this out, join it and start generating money by writing your passion.
