John D. Garcia's Review
An assessment site is a website on which reviews can be posted about people, businesses, products, or services. These sites may use Web 2.0 techniques to gather assessments from site users or may employ professional writers to author assessments on the topic of problem for the site. Early assessment sites included Epinions.com  and Amazon.com.
With the growing popularity of affiliate programs on the Internet, a new sort of assessment site has emerged - the affiliate product assessment site. This type of site is often professionally designed and written to optimize conversions, and is used by e-commerce marketers. It's usually based on a blog platform like Wordpress, has a privacy and contact page to help with SEO, and has commenting and interactivity turned off. It will also have an e-mail gathering device in the form of an opt-in, or drop-down list to help the aspiring e-commerce business person build an e-mail list to market to.
In addition to sites that enable users to post assessments of products and services, there are also those that work on a "professional" or "expert" basis. Some of these sites commission, and pay for, named individuals or bodies with knowledge in a particular field to provide their assessment material, while others hire in-house editorial staff to perform these assessments. By endeavoring to maintain independence and objectivity and allowing their writers' credentials and site ethos to be scrutinised, such sites steer clear of many of the above-mentioned criticisms aimed at user-review sites.
