The article directories on the web are held in high esteem by the search engines like Yahoo and Google. Article directories are part of the linkwheels. The search engines can not judge the quality of an article or web page content. The search engines can merely recognize whether there is an addition to the content or whether an update has been made to an existing content. The article directories that serve as backlinks in a link wheel do not allow articles written by any person to get submitted easily. It takes a minimum of three days for the directories to decide upon the quality of the article submitted by a person. The article directories would sternly reject Copied contents and contents which are not unique. It would also be checked whether the submitted article has relevance and enough of usefulness. Due to all these rigorous scrutiny processes an article that is submitted in an articles directory is bound to be genuine. For this reason the search engines like Yahoo and Google accord very high page rankings for the articles posted in a directory. The website for which the article was written as a part of the linkwheel campaign would be given a very good page ranking.
