Sub Domain Problems

HI

I have a site. prospect of our site is to provide online courses. actually i just want to know that for every courses, should make a diffrent sub domain?
Example
xyz.com is my site name

now for IIT
iit.xyz.com
medical.xyz.com

Is this better way to make site or should make a diffrent pages for this.


Plz suggest me, I am confused.

Thanks
Dhiraj

 

This would be an appropriate use of the subdomain, so feel free to use it. (I'm saying this primarily from an Information Architecture standpoint, though SEO does borrow heavily from it at times - either way, it's still appropriate in this case.)

 

you must use dns tools (bind) vs. u set to many sub domains this way

 

thanks for the nice suggesion
