How can I nofollow my affiliate links?

[2bloggers]

I have a lot of affiliate links and I need to find an efficient way to nofollow them. I have over 500 blog posts and most have an affiliate link. I use Wordpress and Genesis. Any advice?

That would take forever! Seriously! But I have no programming skills whatsoever.

I used http://wordpress.org/plugins/nofollow-for-external-link/ or SEO Smart Links before just to do mass no follow. For affiliate sites that i didnt want to bother with anymore.

The other way is a manual way where you have to get in to every post and add rel = 'nofollow' on each affiliate link but if you have programming skills and can create a  PHP script  then go for the idea suggested above!

You can either create a script to go over the posts, recognize some pattern on the links and add the nofollow attribute, or edit post by post adding the nofollow.

As you mentioned Wordpress, a PHP script should do the work very fast and easily using an html DOM parser.

Here's an example: http://simplehtmldom.sourceforge.net/

and run something like:

foreach ($html->find('a') as $a) {
        if(!checkUrl($a->href)) {
            $a->rel = 'nofollow';
        }
    }

checkUrl is a function you should write to recognize those affiliates links...

Hope that helps!
