I am designing and optimizing a site for a company and had a question about the linking of the site. The company is a big company with many different names that it does business as. For example CompanyABC is the parent company, who sells letters. So there is going to be a site www.companyabc.com, which will have links to its other sites companydef.com who sells only def letters, companyghi.com who sells only ghi letters...etc. I know SE's don't like multiple sites to be the same...but, each site will have different links going to its other pages...rather than having www.companyabc.com/def the link would be www.companydef.com. How will search engines take and respond to this method. Thanks,
