Dear Zenners,

Currently I have this one major site which is doing very well. However, I want to hit certain keywords that I am not hitting by opening a new domain. SO I am wondering:

If my main store is
www.abc.com

Can I open
www.def.com and point to the same data base www.abc.com is using?

This way It would be two physical sites (so search engines will pick it up better). But it would be one central database which would be easy to update and most importantly one customer can sign up once and use both sites....

Thank you
