Our list of Top 50 Article Directories now marks those article directories which use nofollow tag in author’s resource box. These sites are marked with the NF! sign.
nofollow is an HTML anchor link attribute used to instruct major search engines that a hyperlink should not influence the link target’s ranking in the search engine’s index. The HTML code containing nofollow tag looks like this:
<a href="http://www.vretoolbar.com" rel="nofollow">VRE Toolbar</a>
Google announced in early 2005 that hyperlinks with rel=”nofollow” attribute would not influence the link target’s PageRank. In addition, the Yahoo and Bing search engines also respect this attribute. It actually tells a search engine “Don’t score this link”.
If you submit articles to gain PageRank and improve your search engine ranking, don’t waste time on article directories marked NF!
