Trying to help a friend with his Google rankings and i have noticed that he has 4 domains redirecting to his site . When im on his site the original redirecting domain remains in the address box , so it appears as if this is the domain where the site is. Question 1. Will google penalize for duplicate content. 2. Are there any negative effects in terms of seo for using this type of redirect with multiple domains? thanx in advance any advice will be appreciated.
Hi, If he is using 301 redirection for his sites then google will not penalize that site. because this is permanent redirection. your all values will transfer at destination url. If you are using 302 redirection then it can be come under google penalization conditions. Because you are showing your one site at different domain names. that means your duplicate data is present at different domains. Solution: Remove 302 and use 301 redirection to make your site search engine friendly and improve your business and website ranking.
Thankyou so much for your response, How do i determine which type of redirects the site is recieving? when i asked the site builder , they told me cname redirect? thanx
Actually this sounds as though he is not redirecting at all... It sounds more like he is using a URL rewrite. With rewriting, if a browser requests URL A then the server will show them the content at URL B but leave URL A in their browser window. So the content of URL B gets indexed under URL A... If URL B is also indexed with that same content then, yes, you have created duplicate content issues. An easy way to tell is to go to www.urivalet.com and enter the URL that you 'think' is being redirected. If it is being redirected, it will show you something like: - Requesting URL A - Request returned 301 Permanantly Moved... Redirecting to URL B - Requesting URL B - Request returned 200 Ok If it is being rewritten (which is NOT good) you will see something like: - Requesting URL A - Request returned 200 Ok.
Oops. Just saw the CNAME comment... Sounds like the DNS entries for all of the domains are pointing to the same IP address. So you most likely have duplicate content issues. Go to Google and search for a unique sentence or paragraph of text from your home page. See if it comes up under multiple domains that they own that are pointing to the same content. If that is the case then I would suggest using Mod Rewrite (if on Apache hosting) to 301 redirect requests for URLs under the 'other' domains to the same URL on your primary domain. This will fix the duplicate content and give your primary domain credit for ALL inbound links to ALL of those domains. If the other non-primary domains have inbound links, this will strengthen your primary domain's PR and hopefully their rankings as well. It eliminates duplicate content issues and split page rank.
