Welcome to the Q&A Forum

What's the correct method for tagging dupe content between country based subdomains? We have: mydomain.com // default, en-us www.mydomain.com // en-us uk.mydomain.com // uk, en-gb au.mydomain.com // australia, en-au eu.mydomain.com // europe, en-eu In the header of each we currently have rel="alternate" tags but we're still getting dupe content warnings in Moz for the "WWW" subdomain. Question 1) Are we headed in the right direction with using alternate? Or would it be better to use canonical since the languages are technically all English, just different regions. The content is pretty much the same minus currency and localization differences. Question 2) How can we solve the dupe content between WWW and the base domain, since the above isn't working. Thanks so much
