The publishers of Search Marketing Standard have taken on a new project, SEM Compare. SEM Compare proposes to provide visitors with an effective way of contributing and looking at user reviews and rating of SEM Companies.
With the site launch planned for March 17th it appears that the project is ratcheting up its attempt to collect review data from anyone willing to take the time to fill out their questionnaire. If you would like to visit the site and share an opinion the site can be found at http://www.semcompare.com/share.php.
For years Marketing Sherpa has been the most well know reviewer in the SEM / SEO space. Right now Marketing Sherpa offers the information that they collect as a download for sale at their online store. A site like this might offer a different set of insights to complement that report.
