Hi, i have been browsing through many forums and sites with regard to 301 redirects and have a few conerns. Firstly, some forums and sites i've been to state explicitly that a 301 redirect is the most efficient and search engine friendly method of redirecting a domain and that by doing this you will not lose any page rank, ranking positions or backward links, yet others state that there is no certainty whether this will be the case or not. please can someone tell me what the deal is? i can't take any risks with my clients site and need to know what the facts are. the domain i want to redirect is http://www.westbury.co.uk/company_formation/companiesmadesimple/. it has a good PR and plenty of backward links. i need to redirect it to http://www.companiesmadesimple.com. Can someone please tell me what the best way would be to redirect without losing backward links, PR, etc. also, i'm a bit confused as to what a subdomain is. would the westbury.co.uk URL above be considered a subdomain. please clarify for me. Your help would be very very much appreciated. Many thanks in advance.
