Im looking at changing the URL format for my blog. Currently my blog is http://dzrbenson.com/blog would it perform better and get a higher page rank if it were http://blog.dzrbenson.com or http://dzrbenson.com
Depends what you want to be ranked as. I personally would use the blog. approach... that way you are advertising both... your domain, as well as the subcategory. Does that make sense?
If you want to give stress to the word blog, choose the first one. Otherwise go in for the second one which is simple and short. Remember "Simplicity is always better"
Unless your blog is part of a bigger site/portal, don't use the subdomain. If your entire site is a blog, then that's its primary function, and there's no need to have 'blog' in the domain. It's called a sub-domain afterall.
You never know when you would want to separate your blog from your site. So, I would suggest you go with http://yousite.com/blog OR http://blog.yoursite.com
Of course http://dzrbenson.com/blog is fine url but if you want to change it then http://blog.dzrbenson.com will be better than others you have. Because here you are introducing you domain as well as your blog.
Yeah! you can try out using simple http://dzrbenson.com/blog instead of sub-domain! looks perfect to me Stayout simple this way you can get an active PR!
I think he means PR will flow into the subdirectory but it does not flow so easily to subdomains. In my opinion you should only use a subdomain if the content is going to be significantly different than on your main site, if it's the same then use a subdirectory.
