DoFollow blogs have removed the nofollow attribute that is inherent in blogs especially in wordpress blogs.
In doing so, it allows search engines to pass on ‘link juice’ back to your blog.
Here are articles explaining why it is good to build backlinks using dofollow sites. These collections of articles also contain other tips and helpful strategies on building backlinks. I hope you find this resource really helpful.
