Hey Leo!
Thanks for the taking the time to answer me. I am going to set this up exactly as you recommend.
1. I will install the same GA code from domain.com on tickets.domain.com
2. Do you think I need to set the canonical URL on the various ticketing pages all back to the main domain?
e.g. tickets.domain.com ---> canonical to domain.com
e.g. tickets.domain.com/event1 ---> canonical to domain.com
e.g. tickets.domain.com/event2 ---> canonical to domain.com
e.g. tickets.domain.com/event3 ---> canonical to domain.com
and so on?
3. We did make all the header links of tickets.domain.com point straight back to their counterpart on domain.com.
Does this seem like I basically got it all correct?
Thanks again
Adam
