If you want to know what are custom channel groups in GA4 and how you can create one, this blog is for you. 

Dig in. 

What are Channels?

Channels are the sources of traffic to your website or app, defined by specific rules, whereas a channel group is a collection of rule-based traffic source categories. 

Default Channels

GA4 automatically collects data for your traffic sources, categorized into predefined default channels.  

Currently, GA4 has eighteen default channels, and they form the default channel group.  

These include the channels directly representing direct traffic from users entering your website into the URL or visiting from a saved link. 

Organic search traffic represents users visiting by clicking a link after a Google search, referral traffic comes from users arriving via clicking a link elsewhere, and others channel shows sources that do not fit elsewhere. 

Custom Channels

But businesses have unique needs.

To address this issue, GA4 offers to create custom channels for your website traffic sources defined by rules.  

Google Analytics 4 allows you to create 25 custom channels and two custom channel groups. 

You can use custom channel groups in the following ways. 

• View them in reports supporting the default channel group, such as the Acquistion reports. 
• Use them as secondary dimensions in the default reports.
• Build custom reports in Explorations using the custom channels as dimensions.

Why Create Custom Channel Groups?

The question arises, “Why bother creating the custom channel groups”? Let us go over the reasons below. 

1. Use customization - the default channel group does not allow customization. You can still isolate the traffic source critical to your business via custom channel groups. Also, it makes drawing analysis simpler.
2. Retroactive Application - the custom channel groups apply to your current and historical data, which makes comparisons to past data a smooth sailing. 
3. Underlying data remains unaffected - building and applying custom channel groups does not affect how GA4 collects data. So, if anything goes south, you can edit or delete an existing custom channel or custom channel group without losing data. 
4. Custom reporting with GA4 API - businesses not interested or lacking the capabilities to use BigQuery can benefit from customization in traffic sources (channels) for reporting purposes.
