If web directories are going to be able to continue to enjoy the importance they have had in search engine optimization, and if they are to avoid the recent threat of no longer being spidered by Google, Bing, and other search engines, they are going to have to provide useful content other than a listing of web sites looking for page rank. Web Directory Reviews Org evaluates web directories, based on an evolving set of criteria, assigning to each a numerical grade, based on a possible one hundred points. After each round of web directory reviews, the top ten web directories are highlighted, and the evaluation criteria is itself re-evaluated and amended to bring about more useful results in the following set of directory evaluations. Other topics include a blog and general information about web directories, search engine optimization, and related subjects.
