One of the most significant syntax standards for SEO has been established.
The trio of main search engines (Google, Yahoo and MSN Search) have agreed upon a standard for <a tags.
By adding the rel="nofollow" tag to a link webmasters inform search engines of "untrusted" links that should not contribute to search engine ranking algorithims.
The initial use for this tag is blogs, for use in the comments section to curb blog "comment spam" (posting comments just for the backlinks) but is useful for any application that allows user-generated urls (like forums).
Here are some blogs that will support this standard in their software
Brad Fitzpatrick - LiveJournal
Dave Winer - Scripting News
Anil Dash - Six Apart
Steve Jenson - Blogger
Matt Mullenweg - WordPress
Stewart Butterfield - Flickr
Anthony Batt - Buzznet
David Czarnecki - blojsom
Rael Dornfest - Blosxom
Mike Torres - MSN Spaces
Here are the blog entries from the search trio:
Note: Able2Know will support this tag shortly on sites we run and I will add this to the Able2Know SEO mod and publish an update.
