SEO on TDPRI

I noticed that tdpri.co.uk does not redirect to tdpri.com

I think this could hurt search engine rankings. Why doesn't tdpri just 301 redirect the .co.uk to the .com?

it worked for me when i did it as tdpri.co.uk...

Of course it works. I just mean that Google will look at it as duplicate content. 2 different domains, same content.

Need to just do a 301 perma redirect!

See, I have about 10 domains that point here. Some of them are set up as Alias's in my domains DNS records. While some are Forwarded.

The forwarded domain names redirect to TDPRI.COM, but, and I didn't realize this until you mentioned it, the Domain Aliases don't redirect.

I'm very unsure on the 301 syntac to forward those Aliases. If you've got any suggestion on the proper systax I'll add that to my SEO software, it has a section to include 301 Redirects for specific files or domains.

Any help would be appreciated. If you give me one for tdpri.co.uk I'm sure I can figure out the rest.

Thanks so much.
