I have a website where content on few subdomains is the same as on main domain. The reason for this is that I run an affiliate program.
For example affiliate1.mydomain.com has same content as mydomain.com (except different style).
What I would like to know what should be canonical url on my affiliate subdomains. Should I put all links to start with http://mydomain.com (same as on main domain)?
Note: all internal links on affilate1.mydomain.com point to affilate1.mydomain.com/something-here/.
Please suggest me, thank you!
