Google Analytics 4 multi-site tracking
under one account is a very common request from our clients.
You can track:
Subdomains automatically —all visitors to both dogs.example.com and www.example.com, with data for both showing in the same report view (profile)
Subdirectories—only visitors to the www.example.com/dogs subdirectory in a separate report as if it were a single site
3rd-party shopping carts—visitors to your online store and to your shopping cart hosted on another domain
Top-level domains—all visitors to two domains that you own, such as www.example-petstore.com and www.my-example-blog.com, with data for both showing in the same report view (profile)
