[GA4] Custom channel groups

A channel group is a set of channels, which are rule-based categories of your website's traffic sources. Analytics has a default channel group of predefined channels, but you can create your own custom channel groups.

You can use your custom channel groups as a primary dimension in reports that already support the default channel group as a primary dimension (e.g., the Acquisition reports). Additionally, you can use your custom channel groups as a secondary dimension in default reports (e.g., Events report).

Custom channel groups are also available as dimensions in custom reports, explorations, and when you're building conditions for audiences.

Example

Your company, example.com, is running a summer campaign for beachwear and you want to monitor data from the campaign that focuses on social media. You want to

1. Create a new channel group "Summer Swim Social Media"
2. Keep the existing channel Paid Social to capture all traffic-source data related to social media ads
3. Create new regional channels for each of the Facebook Market Pages you create for localized content (e.g., Côte d'Azur, Liguria, etc)

To do this, you could configure each of your new regional channels as follows:

Then, to see your data, use the Acquisition > User acquisition and Acquisition > Traffic acquisition reports and use your new channel group "Summer Swim Social Media" as the primary or secondary dimension for the report.

Each of the channels in your group is a dimension value and will appear as a separate row in the report, for example:

• Paid Social
• Cote d'Azur
• Liguria

Per-property limits

Setting your own default (primary) channel group

Any custom channel group can be turned into your property’s primary default by selecting it as your property’s primary channel group in Admin, under Channel Group admin page.

The primary channel group is initially set to the same definition as the Default Channel Group. You can update the criteria used to categorize primary channel group values at any time by selecting any single custom channel group as your primary. When this is done, the criteria for the selected custom channel group will be used to populate values into the primary channel group dimension on future reporting. The primary channel group serves as your property’s editable default channel group, and is an active record of your properties data in alignment with channel grouping over time.

You can locate this setting at the top of the custom channel group admin page. To set your primary channel group, click on the pencil icon to load a slider that will allow you to select any Custom Channel Group as the new definition for your primary channel group. Data will populate using the new criteria from that point forward.

Create and edit channel groups

In Admin, under Data display, click Channel Groups.

The table lists the default channel group and any additional groups you've created.

Create a channel group

You create a channel group by copying an existing group and making modifications. If you haven't created any groups yet, you start with a copy of the default group. If you have created other groups, you can start with a copy of one of those or with a copy of the default group.
