    Hi there,

    I moved a shop from a subdomain to it maindomain (from shop.domain.com to www.domain.com). On this each and every url has changed + it has been migrated to a new shopping cart.
    Now it was very overworked and did a stupid thing (damn, I dont know why). Now it gets complicated (please red further):

    In the root of the subdomain I made an rewrite rule like this:

    Code:
    Rewrite engine on
    RewriteRule ^(.*) http://www.maindomain.com/$1 [R=301,L,QSA]
    
    This catched all the subfolders with it so http://shop.maindomain.com/category123 will automatically redirect to http://www.maindomain.com/category123

    Now comes the stupid part:

    Instead of redirecting all the sub-subfolders and productpages in this sub-subfolders from the htaccess file in the root of http://shop.maindomain.com/ I created the rules in the htaccess of http://www.maindomain.com/

    First everything went well and the new urls have shown up in the SERPs with the old positions and I thought fine. I tested the redirects and they worked flawless.
    But after 1 1/2 weeks the site dropped dramatically. I did nearly no linkbuilding at all - there was one service but due to the url change and its very safe nature it could not have caused this.

    So the question is does it make a difference for google from where the redirect is started? I really have the feeling that Google feels tricked, because the redirects have been initiated not from the subdomain, but from the maindomain.

    What do you think? Totally nonsense or the chance for a reason for the drop?

    Let me know what you think, I am eagerly waiting for your response!

    Has nobody experiences with redirecting from the wrong root directory and if it influences the way Google counts this redirects? Can this be the cause for a penalty/massive ranking drop?
