Hey guys. I made a hubpage to promote a good clickbank product that has a gravity of 200+ and sells really well. The no.1 domain name for that has only 17 backlinks and I know that I can easily outrank it because I have SEnuke. I blasted a spinner article to all the article directories and all the social network sites using social network nuke module of SEnuke, the weird thing was that even though the submissions were more or less successful, I did not get even 1 backlink. Is it because I am using duplicate content(came with SEnuke). Please advice. Do I need to write my own spinner article to get to the top?
