I have a website available via
www.mydomain.com that is also available via
svr7464z.vps.hostingcompanycom. The content is 100% identical, it's a mirror.
I don't want search engines to know about
svr7464z.vps.hostingcompany.com and probably they never will but just in case they do I want to avoid duplicate content issues.
Unfortunately, blocking the offending URL is not possible and neither are 301-redirects.
So it seems rel=canonical should come to my rescue, but I'm confused where to place it.
Do I have to place the tags only on the
svr7464z.vps.hostingcompanycom pages or also on the pages available via the official domain
Also, do the tags have to be different based on the page?
link rel="canonical" href="http://www.mydomain.com"
link rel="canonical" href="http://www.mydomain.com/about"
link rel="canonical" href="http://www.mydomain.com/contact"
