How to track referrals from an alias domain?
We are setting up a separate domain for the radio campaign we are launching. Our main domain is, let's say, maindomain.com and we are setting up radiodomain.com and directing it (using NS records) to maindomain.com.
In this scenario, will I see radiodomain.com as a referral? This way we want to track how many people visited the website using that domain we used in a radio campaign.
