If a blog has around 18,00-2,000 unique visitors per day(90% from google), with Google page rank I, How much the blogger can expect to get per review from "sponsored Review' or 'Review me'? Any idea?
You want to experiment to find a good price. Don't scare people off by charging too much at the beginning. Start out cheap, like $25 to get a few reviews going, and if the results are positive and the demand grows then you can bring the prices up.
Enter your blog information and Sponsored Reviews will return a price recommendation based upon your traffic and page rank
