Hi, Currently I am doing SEO of a company which has good name in its services, I am facing a strange problem. We have 3 .com domains 1st is for company name (eg.: CompanyName.com) and initially I am optimizing it for same keyword. 2nd is like CompanyNameXXX.com (XXX represents one more word and not adult) 3rd domain is totally different from company name(based on one of the company's product. All domains have PR3 and the CompanyName.com is more than 5 years old. What happend earlier, the domain CompanyName.com was not with us so the company bought other 2 domains and those domains have good number of backlinks from some of the authority sites. After some time the company was able to obtain CompanyName.com and now they want me to optimize it. The Problem: All three domains have same site running, means same html files are uploaded to all three domains, so if i search Google for my company name other two domains are ranking but not the one I wam working on. What i think is we are running same sites on all 3 domains so probably big G sees it as duplicate content and it is not ranking my desired domain. I don't want to loose the benifit of backlinks to other domains, should i just redirect them to the first domain or I read some where that there is some error 300 file or something like that (Just rough memory) [like error 404] which can inherit all the properties of a domain to new domain including backlink power. What should I do, any inputs welcome. Thanks in advance.
