Welcome to the Q&A Forum

So if the placeholder domain you're using here -- "site.co.uk" -- is the same for both the Hubspot blog and your primary domain, this is more than likely what's going on. The only way Hubspot could serve pages on your domain and prevent you from redirecting them would be if you have CNAME records for your domain set up to point to Hubspot's servers. (Essentially this creates an alias.) So if you want your redirects to work, you need to go into your domain name registrar and look at your CNAME records. If there's something in there for Hubspot, then remove it. To answer your questions in order: You can check the index by googling this format, not in quotes: "site:blog.site.co.uk" If it's not indexed, no. Even if they are indexed, no. It just means you probably would not get much, if any traffic to them. I would just make sure the old hubspot blog is down and then add them at your new location, as long as they actually got decent traffic. Then, provided you've taken care of the subdomain/CNAME stuff, write 301s from the old locations to the new ones.

Thanks for your help in this Yiannis. We are now sifting through a lot of the duplicate alias's, creating redirects, and then going into delete them.  Also altered the option going forward.  I have decided to go with 'Do nothing' as i don't want it to make any URL alterations - That should be OK shouldnt it? I guess this is case closed - Really appreciate your time and help in this mate! Sunny

Thank you very much Chris.  Much appreciated!
