I have a number of domains that were 301 redirects to certain area's or the domain (example pizzaparis.com would redirect to the paris page on the site) and for some reason or another lost their redirects. This caused them to fall back as parked domains causing them to duplicate the site.
These have now been trawled by Google and due to a footer link for our sister site it has tens of thousands of incoming backlinks from the duplicate content between the domains. This has caused the sister site (and main site) to drop considerably in the rankings.
We were advised to redirect these domains away to an unrelated page. On a few I setup proper redirects like below as I don't think this suggestion was correct.
This is how I think the domains should be setup:
main.com --> www.main.com dupe1.com --> www.main.com www.dupe1.com --> www.main.com dupe1.com/page1 --> www.main.com/page1 www.dupe1.com/page1 --> www.main.com/page1 localdupe.com -> www.main.com/localpage
He had advised we create a landing page on one of the duplicate domains and redirect like this:
dupe1.com --> landingpage.com dupe2.com --> landingpage.com dupe1.com/page1 -> landingpage.com dupe2.com/page2 -> landingpage.com localdupe.com -> landingpage.com
I think he has suggested this to quickly remove the incoming links which is fine if it will work.
Please advise in which is correct? I've setup most of them to redirect to the landing page as advised but I like would like a second opinion.
It has been 2 weeks now and there has been no improvement in or drop in incoming links reported by webmastertools for the sister site. Searching on google site:dupe1.com is still showing all the duplicated content and the cached is still showing the older footer link.
Any idea on when google would go through and update? is there any way we can speed this up?
