What will rank higher in search engines?

I plan on making 20+ blogs within the next few weeks. I was wondering what would be better for getting indexed fast in the search engines and getting a good ranking, a .blogspot blog or a subdomain blog.

Example:

http://autoinsurance.blogspot.comm

OR

http://autoinsurance.mydomain.comm

What would be a better route to go with? I want to get good SE rankings and do it relatively quickly.

 

A quality blog.

 

They will be quality. Why would I waste my time making shitty blogs?

 

That usually means shitty blogs

 

a quality blog
filled with quality content
embedded in validated HTML
auto creating a validated RSS - or better even mRSS

then submit it manually to all blog directories AND to all RSS directories

 

So the answer it, it doesn't matter which subdomain.

Though on blogspot you risk getting wiped randomly. And AdSense is tough to get to be not about Blogging only.

 

It really doesn't matter if it's a sub-domain or what.. what matters most is the quality. the content, the keywords, the blog design, etc. It's just simple as that

 

Thanks guys. Im gonna go with subdomains on my own server. I feel safer that wa.
