I would like to post some article from other blogs and I will add the url of the original post. What is the best rel="" type for the hyperlinks? Is rel="bookmark" will SEO friendly? I need Googles bles and want to tell that my article is the same as the original, but in different platform and environment.
There's no rel attribute that will help your seo or the seo of the other site. Just the regular link without nofollow is the best thing you can do.
