[GA4] Default channel group

This article covers Default channel groups in GA4 properties. Default channel grouping for Universal Analytics (UA) properties is covered in this article.

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
Default channel group	The channels by which users arrived at your site/app	Attribution model set for the property. Default is data-driven attribution model	Event
Session default channel group	The channels by which users arrived at your site/app when they initiated new sessions	Paid and organic channels last click	Session

You can see the dimensions listed above in the Acquisition reports, the Advertising section, and if you include them in custom reports.

Unassigned is the value Analytics uses when there are no other channel rules that match the event data.

(other) is the value Analytics uses for an aggregated row due to cardinality limits. Learn more

You may see inconsistent data from Analytics integrations for default channel groups if your reports or explorations include dates prior to June 15, 2022. For example, a channel that should be identified as Organic Shopping can be misidentified as Organic Search. Data from June 15, 2022 and later is not subject to this type of inconsistency. You can accurately identify the data from each integration by using the source platform dimension.

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.

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 [e-mail]. 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.
