I've been asked (in order to improve SEO results) to remove a certain web address from a Robots.txt.
I'm struggling (SEO is not my forte) to figure out how to block a certain domain, even though both addresses point to the same website.
For Example:
http://foo.example.com -- Web Address I need to stop from being Indexed
http://www.examplefoo.com -- Web Address I want to be indexed
From What I can tell, using a disallow / will only block from both (as they are the same site)
Any help?! Sorry if this is a silly question..
