Question for SEO people
 

does having subdomains like http://blah.subdomain.domain.com hurt you or is it okay?

yes. I get headache

I have some old sub-domains that has good placements.

It can get good placements, but surfers don't like seeing stuff that matches their results too well.

IE. I search for "adult entertainment website".

Surfers dislike adult.domain.com/adult-entertainment-website.html

I think all of us on this board are constantly surprised at the shit that ranks higher than our own stuff.

What are you basing this on?

use only single level subdomains ... keyword naming the directories and files AFTER the .com will give you much better weight. :thumbsup

Keep in mind that SEs do not see domain.com and sub.domain.com as the same domain, but rather as two completely different domains.

google and yahoo love sub-domains

the real question is:
do you like shemales?

No, it doesn't hurt, but better take a domain, or you'll depend on the host.

alright... but im not sure how to setup dynamic directories so that it is not redirected to some kind of script... anyone know?

I have an itchy rash :(

subdomains like that shouldnt hurt.
