I have heard two arguements to spinning articles and want to clear up which arguement is correct.
The first one is that when submitting your article to article directories you have to spin the content otherwise you will get penalised for duplicate content and say you submitted 10 of the same articles due to penalty one backlink will be recognised
The second one is that duplicate content penalty only applies if the content you post to article directories is the same as on the website. So the arguement goes is youe content is unique (not the same as the content on your website) it is ok to post the same article to the article directories and you will get quality high page rank backlinks to your website
Which arguement is correct?
