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)

Google Analytics 4 ecommerce tracking

Many carts like Shopify, Magento 2 or Woocommerce have great plugins which you can easily enable the ecommerce tracking.

For other apps it is a little bit complicated than it used to be in the Universal Analytics.

Google suggests to use Google Tag Manager for adding ecommerce measurement.

Actually it is true and we modify tags there.
