Sorry for the duplicate question but I'm a newbie and see that I posted wrong the first time. Parked a domain from my previous company website on top of my existing company website. The URL from the other site is now showing for some of my top keywords in the SERPS but with my meta info and linking to my page. How do I fix this?
Do a 301 redirect from the parked domain to the new domain. That will tell the search engines that the existing domain is the main one and will eliminate potential duplicate content issues. It will also be less confusing for your users as they will see a consistent domain when accessing your site.
If you are using Apache you can do this easily with a snippet in an .htaccess file in your root web directory:
