Merging Domains

Hi,

I have two domains. Each has many backlinks and is doing well on it's own.

If I merge the two, will google sum up all the backlinks and treat the two domains as one?

Or will it simply ignore the domain, which has fewer backlinks assuming that the content of the sites will be identical?

Somebody will real live experience on this?

fritzbayer - I'm not quite clear what your idea of "merge" is. You can't have the same content appearing on two different urls.

What you need to do is to decide which of the two domains you want to keep (generally, the one with the most backlinks), and to do a 301 server side redirect from the extra domain to your main one.

If you do this, the extra domain will be replaced by the main domain, and the extra domain will effectively cease to exist.

Visitors and spiders attempting to reach the extra domain will be redirected to the main domain, and only the main domain will appear in your browser's address window. The main domain should eventually benefit from the backlinks of the extra domain.

It's a good idea to list these backlinks before you do the redirect, and to try to get as many of the links changed as you can after you've done the redirect.

I agree with Robert.

I used to have a similar issue with 3 domains that were "mapped" and when Jagger came out I did the 301 and did no link research, it took several months for the links to become stable and level off, I do not really know if all of them have been calculated in Googles BL algo yet, but I will never do a 301 like I did back during Jagger. Next time, I will research the BL data heavily before making that leap.

I can say that now the domain I did the 301 has been stable and the rankings are what they once were (before jagger)

Good luck on that.

I'm not quite clear what your idea of "merge" is. You can't have the same content appearing on two different urls.

I have a website www.h.de and www.d.de. They both resolve to different IPs. The content differs on both sites. Each has around 400 backlinks.

I would merge them by setting the A record of the DNS entry of website www.d.de to the one which www.h.de resolves to. So then the same content appears on two different urls/domains.

What you need to do is to decide which of the two domains you want to keep (generally, the one with the most backlinks), and to do a 301 server side redirect from the extra domain to your main one.

That's dificult to explain. Let me try: I want to keep on running www.d.de, however with the content from www.h.de. So if I do a redirect from h-> then I probably can't use the content of h, or do I?

Of course I could change the A record of www.d.de to the one of www.h.de and then redirect from www.h.de via 301 to www.d.de. Sounds ugly, but achieve what I want.

If you do this, the extra domain will be replaced by the main domain, and the extra domain will effectively cease to exist.

That's sounds like a bad dead. So basically I can throw it away. Then I rather would keep the traffic from it, if I'm not being rewarded for it's backlinks. That's actually what I'm trying to get at.

Visitors and spiders attempting to reach the extra domain will be redirected to the main domain, and only the main domain will appear in your browser's address window.

Thx I am aware of that.

The main domain should eventually benefit from the backlinks of the extra domain.

Any proof? I have seen that the link: command throws the backlinks of several domain into one pod, however, I have no prove that they positively count for the ranking of the strongest of the domains.

It's a good idea to list these backlinks before you do the redirect, and to try to get as many of the links changed as you can after you've done the redirect.

That's impossible, because there are too many and they evolved naturally over time.

i can't find the reference so don't quote me here, but i read that if you maintain the directory structure when merging the domains you will gain some benefit in the reindexing process.
hopefully someone will speak with authority on this...

We did that before (merged two domains) so that if you typed in any-one of the two urls you ended up on the same site.

All I can say is "Don't Do It"

nothing but problems for years and never recovered.
