Default channel groupings are predefined categories that GA4 uses to classify your incoming traffic. These categories include paid, organic search, referral, and others. The system definition of these groupings is reflected in the GA4 reporting view.
It's important to note that you cannot modify the default channel group definitions. However, you can use them to tag your landing page URLs. GA4 does not enforce case sensitivity when using these definitions in your landing page URLs.
For instance, suppose you run an online bookstore and you're promoting a new collection of books through an email campaign. You could tag your landing page URL as "www.bookstore.com/new-collection?utm_medium=email". Regardless of whether you use "email", "Email", or "EMAIL" as the medium, GA4 will group all these variations under the 'Email' channel. This allows you to consistently track the effectiveness of your email campaign.
