I need a help. One of my client's website are highly spammed by last SEO guy. His position is not good now. I check the webmaster tool and see, it has around 15K+(each) links from three article website. Those sites PR is very low and put the link at the footer(May be by the last guy). Now i want to remove those backlinks so how can i do that. I see the Disavow Links of webmaster tool but i didn't use it. For using it, will i just submit the article website url or All pages of the article site.
