Duplicate Content Problem!

[KillAccountPlease]

Hi folks,

I have a quite awkward problem. Since a few weeks a get a huge amount of "duplicate content errors" in my MOZ crawl reports. After a while of looking for the error I thought of the domains I've bought additionally.

So I went to Google and typed in site:myotherdomains.com

The results was as I expected that my original website got indexed with my new domains aswell. That means:

For example my original website was index with www.domain.com/aboutus - Then I bought some additional domains which are pointing on my / folder. What happened is that I also get listed with:

www.mynewdomains.com/com

How can I fix that? I tried a normal domain redirect but it seems as this doesn't help as when I am visiting www.mynewdomains.com the domain doesnt change in my browser to www.myoriginaldomain.com but stays with it ... I was busy the whole day to find a solution but I am kinda desperate now.

If somebody could give me advice it would be much appreciated.

is your site hosted in apache environment?  if so, read up on htaccess.

Something like this should do it;

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.alias_domain.eu [NC]
RewriteRule ^(.*)$ http://www.main_domain.com/$1 [L,R=301]

Hi,

thank you for your response. I think that was nearly what I needed. I used this one here:

RewriteEngine On

RewriteCond %{HTTP_HOST} !^(www.)?lillymeetslola.com$ [NC]
RewriteRule ^(.*) http://www.lillymeetslola.com/$1?domain=%{HTTP_HOST} [R=301,L]

Now every request on every domain but NOT the mein domain should be redirected. Correct?

Can you check that with one of my alternatives if this works properly?
