You can also try getting trackback backlinks, which are another form of backlinks. Trackbacks can appear even on sites where comments are closed.

Do Follow blog commenting is still important especially when you post meaningful and quality posts.

as I know it gets your blog more known and it helps to build backlinks

Instead of focusing on SEO and generating back links on blogs you can focus on the quality of your articles and drive traffic to your site using social marketing. It's a more reliable source of traffic and search engines like social because it's more likely that a human is the one doing the liking or tweeting and now plusing? I've used socialAdr for free automated social book marketing and tweets. I also recently signed up a lot of social accounts and can post to all of them using onlywire. Signing up to more social accounts creates back links and you can more easily target people who are interested in the topic of your site. This is more effective than just putting a link on a random blog and hoping that it will boost your rankings to a top spot. Because even if posting links on random blogs boosts your rankings, it might not last through the next time the ranking system changes.
