I have 3 domains pointing to the same website, with no redirects, so domain1.com, domain2.com and domain3.com show the same content and do not redirect between each other.
If I want to track all domains, do I have to check Multiple top-level domains
in the "What you are tracking" section and add this the following for each domain
_gaq.push(['_setDomainName', 'domain1.com']);
_gaq.push(['_setDomainName', 'domain2.com']);
_gaq.push(['_setDomainName', 'domain3.com']);
Or is it enough to just set it for domain1.com? Or maybe the regular tracking code under "A single domain" will do?
Thank you.
