I've been using wordpress affiliate pro plugin, for my wordpress blog some time now.
I just recently noticed that it MAY not be useful in terms of SEO as advertised.
Say you want to increase link count to a specific post, so you include it in other posts as well. Notice the generated links aren't direct links to the post or page you want to promote.
They are wp aff pro random generated links that REDIRECT to the post or page you want.
How effective is that?
