Hello - I have recently added a new domain to a website in addition to the original domain (a parked domain).  Does anyone know if that will effect the website's search engine rankings - as long as that parked domain is not being marketed/submitted etc.  I really am just trying to make use of the domain name purchased vs having it go to an "under construction" page.  Also - the new domain name is very similar to the existing one (askvetadvice - askpetadvice).  Thanks in advance!

OK - Thanks for the advice - I feel that as long as I am not trying to mislead or resubmit the site under the additional domain, nor am I marketing both domain names, that it should be relatively ignored and I shouldn't have to worry.  Thanks again!
