The real problem is that when I put the old url of this site with www.example.com.br, the competitor analyses only track links and stuff till the change of the domain, because now, all the urls are like www.example.mtv.com.
I have no idea what I could do track this site anymore, because I don't see any change at all.
I think the tool itself should realise that I just want the "subdomain", even if that is no relation between the sites.
