Is having more than one domain point at a website a bad thing?

In google's eyes?

 

Not if you do it with 301 redirects.

For example: Any good webmaster has both example.com and www.example.com pointing at their web site. That's two domains right there.

If you have two domains pointing to the same file area in your Apache conf... I do not know.

 

It seemed to be a useless venture for me. Because google only indexes one. For instance, if you have abc.com and xyz.com, if google sees and index xyz.com first, then it sees abc.com, then if you do any searches for abc.com, like site:abc.com xyz.com shows up. It only seems to index the first one it sees, and it knows the other just points to it, so it's not worth much.

I thought it would help if I had a domain with keywords in it, but it never really showed up in google, so it seemed like a waste for me, especially if it's a new domain and doesn't have any PR to pass on to the site it's pointing at, then I think it's not worth much, if anything.

That is just what I saw when I tried it, it could be different for other folks.

 

I'm with Will. As long as the server response code comes back "301 Moved Permanently" I don't see a problem.

 

Hi,
I just wondered how Amazon do that though.
They have lots of extensions all pointing to them.
Like .com and .co.uk for instance.
They all have the same PR as well.
Are these all mirror sites? and if so, how come they don't get a penalty, like having their mirror sites dropped in to cyberspace.
I assume that the main site would be .com

Also, I see the main reason to have a mirror site. That's when you want to target a particular region. Some search engines will only list .co.uk for UK searches for instance.
A UK .com company would need a .co.uk extension if it was to show in the SE's results.

 

Amazon isn't pointing their localized sites to their main page, the localized pages each have their own content - ie. amazon.co.uk doesn't redirect to amazon.com, rather it's their UK site which is different from Amazon.com - no pointers involved here

 

Thanks,
Point taken.
They still have a very High duplicate content though for the .com and .co.uk sites.
Don't you agree?

 

I have lots of mirrors with PR and dup content - they just dont really show up in the serps.

 

Not really, the layout of the yahoo.com & yahoo.co.uk pages may be the same, but the content is greatly different.
