Comment (with quality comments) on other popular blogs, its a great way to get free (and one way links), if your comments are good it also drives traffic.
Go to http://www.pingoat.com Then every day that you updated your blog, use their free service to ping it out.
I use pingoat regularly but don’t have proof that it works “gives trafficâ€. Just pings a lot of blog search engines and other “sites†that people just don’t use.
What I did and has some successes was to visit blogs of interest and leave comments. You get the feeling that you are working to promote your blog and also the results are quick to appear.
