Yes, you are diluting your domain authority by having multiple domains service the same = content. There's even a potentially worse problem though... Depending on how many domain names you have, more than 2 or 3 maybe, Google will view your single website as multiple websites. This is = known as duplicate content.
Google knows not to penalize someone for the "duplicate" version of
www.domain.com and simply
domain.com, but when it comes to things like:
www.domain1.com domain1.com www.domain2.com domain2.com www.domain3.com domain3.com www.domain4.com domain4.com www.domain5.com domain5.com then Google starts to get upset because this looks like 10 different websites. =46rom their point of view, you've sold = or syndicated your information, and it will work against you.
Many of the sites I manage have 5 or more domain names we use for offline marketing. I use a few different methods to handle = this. Normally, I would just use the domain forwarding feature with GoDaddy to 301 the alternate domain names to the primary domain names. But I also add extra Google Analytic UTM tracking = codes so I know what domain the person used in the first place.
However, for your situation, since you already have pages in the Google index, you should change your Apache configuration to test the domain name, and rewrite the URL to the primary domain = name. That way you can still keep the pages and variables. You = would want to make sure the Apache config uses a 301 to indicate the changed URLs.
You could also build this feature into WebDNA using the
[redirect] context, but you might run into issues depending on which version of WebDNA you are using because the
[redirect] is a 302, not a 301. Using a 302 will not solve the duplicate content = issue.
Hope that helps,

Hi
Just looking for a bit of advice - I have a site that is available via many different domains and at the moment there are no redirects so if you arrive via
domain1.com then every page thereafter stays on that domain, likewise if you arrive = as
domain2.com it stays there but all the content is the same from the same = CMS.
My question is do you think I am wasting Google ranking by effectively sharing out my hits across domains or do you think I should redirect all requests to one of the domains?
I read somewhere that I am weakening my position a bit because my "popularity" is being shared out across multiple domains, it seemed logical just wondered what everyones experiences were.
If redirecting is the answer, what is the easiest way on an Apache server, using WebDNA or using an Apache redirect?
Thanks for any input.
Cheers
