I have some sites where i advertise various products. At the end of the article the customer see something like "Buy now your productX on amazon". Now i thought submitting each of these articles to webdirectories and also putting in my Backlink. So that i get some money through Bum Marketing + a backlink from the article directories. Google can´t punish me for that because so many newssites are posted thousands of times. So will google reward me for that? What are your experience in BL from dublicate content sites? Forumprofiles have often many dublicate textcontent, too. So is that a similar case or not comparable? And if not, why? THX!
