Geared specifically at Google, today we are talking about the NOFOLLOW tag.
There are dozens upon dozens of articles written on “should we use nofollow?” or “shouldn’t be we using nofollow?” among other questions as well. Today I am tackling the issue myself.
NOFOLLOW is a tag that Google created as a means to fight back against spam on blogs. As of today, Google is the only search engine actively using the tag as an integral part of their algorithm. The NOFOLLOW tag simply tells Googlebot to not follow — aka don’t give any link love — to the link you have on your site with that tag. Yahoo! and MSN do not care whether a link has nofollow or not, they will follow the link you provide them.
WordPress has, by default — and for a long time now — nofollow’ed all links to authors in comments. I finally opted to install the plugin TOFOLLOW. I’m using this plugin to actually FOLLOW the links in my comments. As you can see on an article with comments that I am indeed following all the links pointing to the authors of the comments.
Since spam fighting tools are so abundant now for WordPress, there’s really no reason that WordPress should still be using the nofollow tag for comments.
