Custom channel groups in Google Analytics 4

GA4’s Custom Channel Groups are rule-based traffic categories based on site visit sources.

Grouping channels gives you a high-level overview of what marketing channels are driving revenue and lets analysts understand which channels are the best performers. This is important for the channel’s optimization.

Through the Traffic Acquisition report, you can see your data organized according to default channel groupings like organic search, refer, direct, paid, etc..

The difference with the Default Channel Groups is that now GA4 increases the flexibility of creating these groups according to the rules that are set.

Previously, there was no option to add your own channels. Now you can create new channel groups, change groups, change channels in a group, add new channels to a group, remove them, reordering, etc.. 

Custom channel groups also serve as dimensions in custom reports, explorations, and when building conditions for audiences. This versatility allows you to leverage custom channel groups across different analytics features, enhancing your ability to segment and analyze data in a way that aligns with your business needs.

This allows you to customize your channels to better fits company’s preferences.

Limitations of Custom Channel Groups

There are the following limitations in the GA4 Custom Channel Groups:

Standard Properties360 Properties
Groups per property25
Channel within each group2525

And yes, the Default Channels Groups are excluded from this count.

Creating a channel group helps categorize traffic-source data based on reporting needs. 

For example, a new channel group can be created to monitor social media exposure of a spring campaign for camping. 

Regional channels can also be created for localized content. 

These channel groups can be used in Acquisition > User acquisition and Acquisition > Traffic Acquisition reports to view data associated with each channel.

Each channel in the group appears as a separate row in the report with associated data like the number of new users, engagement rate, and conversions.

Additionally, custom channel groups may not cover all scenarios, especially if your website receives traffic from unconventional or emerging sources. It’s essential to regularly review and update your custom channel groups to accommodate changes in your traffic sources and ensure accurate data analysis.
