This article covers Default channel groups in GA4 properties.
Default channel groups can't be edited in GA4. You have the option to create custom channel groups, which let you create your own rule-based categories of web-traffic sources.
We recently made improvements to default channel grouping for Google Analytics 4 properties. Learn more
Channels are rule-based definitions of your website's traffic sources that let you monitor the performance of all of the channels sending traffic to your website. You can find descriptions and definitions of the channels in the tables below.
You can see the default channels as values for the following dimensions:
| Dimension | Definition | Attribution model | Scope |

Editing the default channel group
It's not possible to edit the GA4 default channel group because Google maintains a universal default for all users that can be kept current, accurate, and serve as a reference for the life of every property.
You can edit the primary channel group at any time, which serves as your property's editable default channel group.
Learn How to enable the primary channel group.
Analytics' list of sources and categories
If you would like us to add your search, social, video, or shopping site to the list or if you would like to make a change to your current listing, contact us at [email protected]. Google Analytics reviews these requests at least once per year and often more frequently. Inclusion is based on Google’s assessment of a number of factors including but not limited to whether a significant volume of traffic is sourced from a given search engine, social site, or shopping site.
