Let's see if the second link sticks. My first attempt was a week ago were I've used exact keyword phrase linking to a post with many amazon links. The link was placed inside the body of the wikipedia post, but was removed within minutes. My second attempt were 10 hours ago and the link is still there. This time I did not use exact keyword phrase and placed it within the reference paragraph. The link is going to a post with no affiliate links and maybe this is a good thing. So if the link sticks and the post is beginning to rank I will definitely put some affliate links inside the post. If the second link sticks I will try again in a weeks time with a third link using the same pattern to see the outcome. And not a contributor to wikipedia and maybe this will help someone creating links on wikipedia.
