I would like to know what is the best way to leave my affiliate link in a blog comment. I will be giving valuable comment about the blogs content then leaving a link. Should I just put the URL in the comment? Should I shorten the URL? What is the most effective way? I have set up Google alerts. Every time Google alerts me to a new blog post or video etc I will leave a comment. Any advice from any one who has had success with this method would be highly appreciated. I will also be doing forum commenting with the affiliate link in my signature. Thanks.
