Should I use change of address when moving to subdomain

[awrikat]

Hi guys

So we had a domain that was only for one country, www.example.com

1 year later we decided to go to another country so we will have all the current website under a country subdomain like : ae.example.com

we did a 301 redirect
Should I perform a change of address action from www.example.com to ae.example.com  ?

please help
Thanks

I am a little unclear on the question however a 301 redirect is the best way to tell google to forget about the old URL focus on the end URL of the redirect.   It is as clean and efficient as you get.

But to be clear direct from google webmaster:-

"301 redirects are particularly useful in the following circumstances:

• You've moved your site to a new domain, and you want to make the transition as seamless as possible."

Hope that answers your query.

I assume you mean an "official" change of address in Search Console?  Yes, if this is an official, permanent move then you should do the official change of address in WMT.

Use the change of address tool

If you've moved your site to a new domain or subdomain, use the Change of address tool in Search Console. A change of address notification helps you manage the transition needed by Google to index your new URLs at the new address, while minimizing impact to your current ranking in Google Search results.

Thank you for your answer: we did a 301 but I was considering the "change of address tool" to make sure we don't lose any backlinks.

Thank you for your answer,  yes we moved from www.example.com to
uk.example.com and the new countries will have 
us.example.com

now since all old links were for the www.example.com UK we are thinking of using the  change of address in Search Console.
