Should go for domain name?

I think it's totally depend on what is your blog's specialization and how can you manage more traffic if you have new domain name for your blog. If your blog are running on a free blog provider and you have many loyal visitors already, i think you can keep using that blog. Otherwise you want to make new blog with your new domain name. A domain name for a blog however can give a more prestige for your blog anyway. So, it really depends on how's your blog's current statistics. Have a nice day and happy mylotting.

Focus on titles, keywords and descriptions, and create links that are related to each other, create a spider web if one is indexed to one of the major and minor engines. And create a topic that is suitable today. Think like a visitor, what are you searching for. And submit it to freewebsubmission dot com, it will automatically submit you site to as many site as there is available.
