Mutiple domains pointing on the same web site issues

[opic]

We have in out company lots off different domains pointing to the same web site (On for most major countries actually...) . Unfortunately this was done by having all the DNS names to point to the same IP address to the target web site, and not by using a redirect as should have been done.

As most of the pages on the web site are linked internally (All the pages of the site links at least to the front page), this resulted to have all the different domains linking one to each other causing artificial external backlinks to our main .com web site.

I just wonder if google is giving us a penallity for this backlinks ? Also this causes the same content to be shared among different domains, resulting probably to self competition for keywords.

Should we now remove all other domains resulting to a loss of these "artificial backlinks" ?

No just get your 301 in place, make sure all internal links point dirctly to the domain you choose so not to get un-necessary redirects.

Then your link juice should consolidate within a few weeks
