I think what like technoguy says when you are promoting CJ you have to put some work into it. It is the same for any affiliate page. You don't want to promote the page directly since most people have seen the same page a thousand times.

You might want to consider a teaser page or offering free information that indirectly promotes the product you are selling from cj.

You should see a better response from this method but of course there are always other ways.
