Is sub-domain is considered as different or new domain by search engines or not.

Hello,

I have a query :

Is sub-domain is considered as different or new domain by search engines or not.

Like my websites www.daniweb.com so www.domain.daniweb.com will be considered as new domain or different domain by search engine on not.

Also if i place links from subdomain to other websites, will that be considered from my main domain or from sub domain.

Little confused.........

I read some where in forums that sub-domain are considered as new domain but not sure.

Thanks

I will not place links from sub domain to my main domain. I will place links from subdomain to someone else domain.

subdomain's with real content is normal same as other domain.

10, 100, 1000... subdomains in a short period is dangerous. Black list or Long Sandbox

I believe subdomains are looked at as just that ... sub-sites or mini-sites which are self-contained. I think their biggest problem as far as SEO (and usability!) is concerned is that you can't use relative links among various subdomains of a single site.
