Ninja Affiliate Dealio
Then I read about a plugin on Shoemoney.com called the Maxblogpress ninja affiliate dealio. This plugin costs some money but accomplishes the same thing automatically without having to link to your site's directory for the redirection. Great, but I have a free solution already working on a number of my sites.
A Free Similar Solution
Today I came across another Wordpress plugin called The Cross-Linker which automatically ads links to your content for certain predefined words within your posts. I works very easily and will import links from your blogroll to link to the blogs you already like. The only downside is the link is a direct link to the external site. I like this solution and may use it and hope for the best with Google. Now if only DotNetNuke would start to have quality free modules for end-users.
