rel=”nofollow”
The nofollow attribute is used to stop search engines using links to affect the ranking of pages in an index. The idea was originally developed by Google as a way to stop links being use to artificially inflating the ranking of a specific page.

Most search engines will follow the links but exclude them from their ranking calculations (Goole, Yahoo). Others leave the link without following it or using the links (MSN). Some search engines still don’t recognise the attribute (Ask) and use the link like any other.
The most common use of nofollow is on blogs where spammers can often post comments which contain links to various websites. Nofollow should be used when a link is unknown, when the editor cannot vouch for its authenticity. This is the case when a third party leaves a comment on a website.
