The question is there is one site named: www.example.com
.
But the issue with site is it can open after entering whatever instead of www.
e.g.:
xxx.example.com
john.example.com
micky.example.com
Is this a fault in the site? Can this affect SEO results?
john.example.com
? Do they see the same content as when they visit thewww
? Do they get a redirect? Do they get an error?
