No Follow Tag

No Follow Tag

A no follow tag is an attribute that is sometimes given to outbound links so that they do not pass ranking weight or PR to another site. The idea for creating a nofollow tag has been credited to Matt Cutts and Jason Shellen in 2005.

Google & The Nofollow Tag

According to Google's official statement links with a nofollow tag are not followed at all. Other search engines including Yahoo respect the tag as well. Yahoo follows links with a nofollow attribute but ignores the link when determining their ranking results.

Reason For The Tag

The nofollow tag was created to reduce the effectiveness of spam. For example, by automatically setting blog comment links to have nofollow tags the links will be ignored by search engines. This will also help search engines return results that have not been influenced by blog comment spam. Webmasters sometimes add nofollow tags to paid links in order to avoid any penalties a search engine may give to sites selling links.
