Blog Commenting is also one of those old methods which used to work but not anymore. It will works for traffic if the blog is a popular one. 99% times you are getting nofollow link when you are doing blog commenting. Another problem is if the link to be a quality one then page has to have a high DA and PA too. Usually in a case like this you will find 100's of comments in each post. That reduce the value a lot even if it's a DoFollow link. These days Google consider this type of links spam if you have too much of these.
