Add rel="nofollow" Attribute To URLs - Reduce Spam - Increase Pagerank
 

This little hack will edit all the URLs within posts and signatures and add a rel="nofollow" attribute to them.

This will do a number of things. First and most notably, it will reduce spammers because search engines will no longer follow these links. It will also stop your pagerank from leeking onto other sites. Also, some people say that adding nofollow to your URLs will increase your Pagerank. This is more of a matter of opinion, make up your own mind about it :p

vbSEO users already have that but thanks anyway ..

Alot of people don't want to buy vBSEO so this is a nice free alternative :)

Google announced in early 2005 that hyperlinks with rel="nofollow" attribute[3] would not influence the link target's PageRank. In addition, the Yahoo and Windows Live search engines also respect this tag.[4]

How the attribute is being interpreted differs between the search engines. While some take it literally and do not follow the link to the page being linked to[citation needed], others still "follow" the link to find new web pages for indexing. In the latter case rel="nofollow" actually tells a search engine "Don't score this link" rather than "Don't follow this link." This differs from the meaning of nofollow as used within a robots meta tag, which does tell a search engine: "Do not follow any of the hyperlinks in the body of this document.".

Thanks for clarifying some stuff there. The pagerank thing is believed by some people, I was sceptical though :rolleyes:

thanks :) installed

Thanks! This will work well on my sites that don't have vBSEO installed :)

It doesn't stop any spiders or bots from following links.

Major search engines like Google, Yahoo, Ask, ect...wont follow these links.

No, it won't. It may stop spammers from benefitting as much from those links but it won't stop them from posting the spam.

"PR Leak" or "PR Bleed" is a persistent and longstanding myth, but it is nonetheless a myth. Your forum pages don't lose PageRank by linking to other pages.

Those people, whoever they are, would be totally wrong.
