How to understand visitor path conversion across multiple subdomains
So I have my analytics code running across multiple subdomains (2 different ones). One subdomain is for landing pages and one is for the main website. I'm also tracking form submits and conversions on each subdomain.
What is the best way for me to understand the journey path of visitors from subdomain of landing pages to main website as well as how many conversions happened where the visitor started on the landing pages and converted on the website? What would be the best way to set this up?
