I have what is probably a very simple problem, I'm just having trouble wrapping my head around it because it's so simple.
I have a website which talks about 2 items. I've just bought another domain that refers to one of the items and want it to point to the part of my website that refers to that item. Since I don't have a second website - just want to point the new domain to an existing domain, do I even need a redirect? I've pointed a domain name to an existing web site before (not a 301 redirect) but not to an internal page of an existing web site.
Example: www.dogcatsite.com is the existing site. Part of it is devoted to dogs, i.e. www.dogcatsite.com/dogs and part of it is devoted to cats, i.e. www.dogcatsite.com/cats . I just bought the domain name www.dogheaven.com. When someone types in www.dogheaven.com, I want them to go to www.dogcatsite.com/dogs .
What's the best way to do this without getting dinged for duplicate content in the search engines?
