Domain vs. Subdomain vs. Directory

[carcassi456]

What are some of the cons/pros of the following places for blogs?


1)purchase a website down just for your blog
2)put each of your blogs on a subdomain of the same domain
3)put each of your blogs in a different directory on the same domain

For example:
1)www.asiansexblog.com
2)asiansexblog.sexsite.com
3)www.sexsite.com/asiansexblog/

Which options do you think work better for SEO / SE traffic / pagerank / alexa /quantacast /etc ?

Thanks.

for a "main" blog that is less splog like I would make it www.domain.com

for feeder type or more splogish type blogs I do those on subdomains.

for SEO if you have a couple decent inbound links to a subdomain it's going to get traffic. Heck I've got some that are all in sup index and they still get plenty of SE traffic. splogs I just rip and move on. see what happens with them and learn from them. I don't focus that much time on going back on them. Learn and move on.

Nice post. I was curious about the same thing. From my understanding each subdomain is treated like a separate domain name. If your main domain name get penalized your subdomains will be feel it. It's not a good idea to put links on the main domain pointing to any of the subdomains. Is it okay to link subdomains to subdomains? I don't know.

Here's a quote form something I recently read

> A main domain which has incurred a penalty can pass that penalty to any of its subdomains or subdirectories regardless of links...

> A subdomain which has incurred a penalty will not pass that penalty to the main domain unless the main domain acknowledges the subdomain with a link. Or, complementarily put:

> A main domain which has not incurred a penalty cannot be affected by penalties placed on any subdomains, unless that main domain links to the penalized subdomain.

I also read that in the future Google plans to treat each subdomain just like any other URL from the domain. This means that a subdomain can have a lower rank on a searched query than it has a few months ago.
