Got an .eu domain, if I point at it my site will SEs see it as duplicate content?

My main site is doing well, I got a related theme .eu domain, and want to point it to the same site, but do I risk getting banned from search engines for duplicate content?
Both domain names are good so I want to maximize on it.

Now I have a .eu domain name (not the same wording as my existing domain name) what's the best thing to do?

 

No you will not get any penality.

 

I suppose redirecting a domain to your main site will have you penalised from SE probably. I have suffered from penalisation on one of my sites. I suggest you get some more opinion on this topic.

 

admans, its not a redirect. Its just another domain name pointed to the same site.
I have had redirects in the past and google didnt like them at all.

Thanks for the comment Mong.

 

Oh ok...cool. That way it doesnt hurt. Eg. Namepros.

 

301 redirect ONLY

 

Hi Jim, do you mean that a 301 redirect only is a problem?

 

No. I mean that nothing else than 301 is a problem.

301 is the only valid redirection for SEO.

And don't put a copy of the site there, that's dup content.
