Are you one of the victim being slapped by Google in the last two most recent PageRank update, for writing paid posts on your WordPress powered blog? And now, you wanted to be a good boy again, not writing anymore paid post, but not knowing what to do to all the old paid posts?

You have three choices, just leave it there, or insert “nofollow” to every single link you have in all your paid post, manually, and the last one, use a plugin namely NoSpamLinksPlugin to do the job.

The plugin consist of only one php file. After uploading it to your wp-content/plugins directory, you can configure it right way in your Options panel. Assuming you have a category for paid posts, you can nofollow all the links in that particular category easily.

Just select your paid posts category in the All No Follow section, and enter how old the posts should be before the nofollow is added. Voila, all your paid posts links are now nofollow-ed.
