For comment on Blogs check whether that site is having traffic, there you can give a comment which in turn can give you traffic. Don't directly give links of your blog first read the article then give the comment about post. If you are saying anything useful then mention your original name so that more than one person will click on your name to get more information. More over if your blog is not related to that content then give the home page URL.
I hope this article gives you details about how to generate the traffic without google. Share this so that new bloggers may also get this to build their blog. Dont forget to share!!!!!.....
