I am going to be creating some niche related web 2.0 to be used for backlinks. As I will be making these blogs seem 'real' I will need to bulk them out with a few articles that dont contain links. As I dont have the funds to order 100's of articles to use on them, do you guys think it would be safe to use PLR articles instead? Obv. I will be using unique article when it come to backlinking so there wont be a dup content issue with those, but if the rest of the blog has dup content, will it affect my backlinks?
