What happens when a de-indexed subdomain is redirected to another de-indexed subdomain

Hi all,

We are planning to de-index and redirect a sub domain A to sub domain B. Consequently we now need to d-index sub domain B also. What happens now to the link juice or page rank they gained from hundreds and thousands of backlinks? Will there be any ranking impact on main domain? Backlinks of these sub domains are not much relevant to main domain content.

Thanks

    When de-indexing the sub domain B, you will automatically lose all backlinks and also the ranking.
    But to your main domain there might be some dip in traffic and ranking as some of the link juice maybe gained from the sub domain.
    To conclude, yes you will see dip in traffic as well as ranking on main domain, but that is temporary only.

      Hi Dianna,

      Thanks for the answer.

      Why we loose all backlinks if we de-index sub-domain B? We are not taking it down right? Just deindexing. Still the pages will be intact right and website will be working. Please reply and clarify me.

        Alright so I misunderstood. Why are you deindexing a site that has gotten links to begin with if it still is going to exist? I see people talk about this but 8 times out of 10 its NOT the solution to any real problem.

          The reason to deindex these sites are....they are kind of forums where our product users will create own threads and content. Promotional spammy content has been increasing and we can't control it with manual work. We need these sites but don't want users to spam it for their promotional content. So decided to deindex. Is this Okay? Still these sites will have same backlinks right? Will there be any impact on ranking of main domain?

        Hi Micheal,
        I'm sorry I mistook for down the website and was talking about backlinks. You cannot deindex subdomain as Byrede said. You have to either 301 redirection or block it from robots.txt and remove the url from sitemap.xml

    This is a little confusing. Why do you need to de-index subdomain B?

    When you redirect subdomain A to subdomain B, the links and authority of subdomain A pass to subdomain B.

    However, if subdomain B is de-indexed, that won't matter much because it is not going to show up in search results anyhow.

    unless I am just reading this wrong then lets forget about the whole deindex thing.

    If a site or subdomain no longer exists then there is little reason to worry aobut deindexing it (that happens automatically).

    so its a matter of redirection and the only thing you should worry about is links to those sub domains beign conveyed to the still existing site,

    If you have got links pointing to those subdomains then you should redirect both to the new locations NOT try and do a double redirect

    but agree with MikeF above - confusing OP the way it was put.

    I think deindexing works on a domain, not subdomain. Because if you deindex a domain, all of its subdomains will also be deindexed. However, if you are blocking the subdomain in robots.txt, Google and other search bots can still access the main domain and will not access the specific subdomain that is blocked in the robots.txt.

      The intention behind deindexing is to stop users on these sites posting promotional content. So no new pages of the site will be indexed in Google except rare cases. So users will not likely post any spam. My intention is to know whether there will be any ranking dip for main domain due to de index of these sub domains? Yes. we are going to block via robots. Is that fine?
