I would like to add CJ affiliate links to my info site. I would like to create a whole new section on my site with info and links to this affiliate program (20 to 50 links on each page on the new section). I am using nofollow attribute but I am still concerned about the impact of the affiliate links on the SEO for my site. Has anyone done this and noticed a negative impact on SEO?
