I have a 2 domain names same company name.com and same company name .net . Both are hosted in my Go daddy Hosting account in a single account . Same company name.com .is the primary domain and same company name .net is the aliased domain . Both are listed by major search engines like yahoo and google . Now I want to remove the aliased domain ie same company name.net . Will I be penalised for removing the aliased domain by the search engines Would be very grateful for a straight answer .
