<a href=”…” rel=”nofollow”>…</a>

In an effort to reduce what is commonly referred to as “Comment SPAM”, you should consider adding the rel=”nofollow” attribute to any ‘user provided’ link in your website (or Blog). Doing so will prevent many search engines (spiders) from giving the linked site additional ‘value’ or ‘relevance’ because of a multitude of links from around the web. It doesn’t remove ‘value’ from them, just makes your site not give them any additional weight.

To my knowledge; Google, Yahoo!, and MSN all support this markup.

Simply put… the intended effect of this is that any link containing rel=”nofollow” will allow both users and search engines to reach the site, but the existence of the link will not increase the ranking of the site in participating search engines.
