Web site data multi language
I have a website, let´s say mydomain.com and it is a multilanguage website which I optimized for the pt.mydomain.com (for portuguese keywords). My question in here is I have separated in different properties in Webmaster tool. Should I do the same in Analytics so I control the data to that specific sub domain? Because it will take me into another problem, if I add more 2/3 languages. I will need to create different properties to collect data from each one in analytics. Is there any simple solution for this? I have them both separated in SEO tool that I use (SEMrush) and Webmaster.
Thanks in advance.
