Optimized Domains?

Hi, I know this is a newbish question, but is it possible to optimize a domain name? I have bought some domains with my keywords in them and was wondering if there is anything I can do to optimize them besides just pointing them to my site. When I type my domains in google they don't appear, but of course they will go to my main site if I type the address in. So my question is what can I do to optimize them to bring traffic?

thanx in advance for any help!

 

How old are the domains?? If you just reg-ed them "G" won't notice them yet.

 

Develop them or Park them

I think the idea of the guy is to point these domains containing specific keywords for a site he has mentioned to this particular site.
I don't know if there is much to be optimized in this case though...

 

Thanks for the advice, I guess the only thing I can do is either point them to my main site or host each domain and optimize them and then redirect them to my main site.

 

I don't think this will help in a long run. When you redirect them after some time google will reindex them and the previous optimization will be lost.
