The median expected salary for a typical Writer II - Web in Lansing, MI 48917, is $56,468. Researches and writes online content for a company’s web site. Stays abreast of current industry standards and techniques to ensure effective content that achieves the organization’s goals. Requires a bachelor’s degree in a related area…

Based on that figure, my base charge for writing a product or site review that takes one hour to complete should be $22.00. Which makes me wonder why there are bloggers on ReviewMe and Sponsored Reviews charging three and four HUNDRED dollars for a review. Unless the review is really taking 15 hours to research and write, which seems unlikely. And it makes me wonder if I am charging realistic prices for reviews after all.
