PayPerPost (PPP) is a website which helps content creators such as bloggers, videographers, podcasters and photographers find advertisers willing to sponsor specific content. The advertisers create opportunities ("opps") that describe the content they are looking for (e.g. feedback, reviews, buzz, creative, video). The bloggers (sometimes referred to as "Posties") then choose opportunities in their area of interest.
Once the blogger has written a blog post or posted a video that matches the requirements, PPP then reviews the post against its requirements (e.g. topic, tone, length) and PPP terms of service (e.g. disclosure required, no adult content), and handles payment.
The company recently (as of April 2007) introduced a segmentation system whereby advertisers can limit which bloggers qualify for their opportunity. The system uses criteria such as Google Page Rank, Alexa rank, blogger quality rank, RealRank and blog categories. They can also exclude blogs on certain domains.
