Domain
Make sure your domain setting excludes subdomains (meaning remove `www` as well)
Ex: https://yourawesomesite.com
Subdomain conversion tracking
This is a critical for revenue tracking on many sites. If you utilize subdomains (i.e. if your primary website is mysite.com but the checkout is on shop.mysite.com), this will enable tracking between subdomains and their respective origins by using cookies to store experiment data.
