Google Analytics 4 is the current version of Google’s marketing analytics tool, which simplifies advertising campaign audits. However, after migrating from Universal Analytics, even experienced marketers may encounter difficulties due to the updated operating logic, interface changes, the disappearance of some reports, and the introduction of new data collection parameters. Let’s break down how GA4 traffic channels work.
What Are Traffic Channels in Google Analytics 4
Channels are traffic sources grouped by certain characteristics. Their purpose is to provide data on the paths users take to reach the site and the effectiveness of attracting the target audience. Google Analytics 4 traffic channel groups are traffic sources classified by specific attributes to distinguish between different types of traffic. GA4 differs from Universal Analytics by the presence of new categories.

New GA4 Traffic Channels Not Present in Universal Analytics
Cross-network – traffic generated by advertising running across multiple platforms. These are typically Performance Max or Smart Shopping campaigns that display ads in search, social media, Google Shopping, Gmail, YouTube, and more. These GA4 traffic sources allow you to evaluate the effectiveness of comprehensive audience acquisition solutions.
Organic Video – organic traffic analysis from free content, when a user clicks a link in a video description on YouTube, Instagram, TikTok, and so on. This channel helps identify which video platforms generate organic visitors.
Organic Shopping – visits resulting from organic product/service searches on trading platforms and marketplaces (OLX, Prom, etc.).
How to Perform Google Analytics 4 Traffic Analysis in Reports
The “User Acquisition” and “Traffic Acquisition” reports are ready-made collections of marketing information. The first provides data on which channels best attract new users, while the second covers traffic sources overall, including new, returning, and repeat visitors to the site or app. The “Traffic Acquisition” report also enables cross-channel traffic analysis in Google Analytics 4. To access it, open Google Analytics, select Reports → Traffic Sources → Traffic Acquisition / User Acquisition from the left-hand menu.
Tips for Custom GA4 Channel Configuration
Custom traffic channels in Google Analytics allow you to classify traffic according to your own objectives. This enables more precise source analysis and tracking of the effectiveness of achieving specific business goals across different platforms. GA4 channel configuration uses parameters such as source, UTM tags, keys, attribution, and more. The most convenient way to create Custom Channel Groups is to copy a standard group and adjust the parameters to suit the specifics of your project. Step-by-step instructions: Admin → Data Display → Channel Groups → Create.
UTM Tags and Their Impact on Channel Grouping
The format of UTM tags determines which channel group traffic is assigned to and how it is classified. UTM tags are code snippets added to the end of a URL. There are several mandatory and optional tags.
| Parameter | Data | Value |
| utm_source | The search engine from which traffic originates | utm_source=googleutm_source=bing |
| utm_medium | Type of traffic | utm_medium=cpcutm_medium=cpmutm_medium=email, etc. |
| utm_campaign | Reference to a specific advertising campaign | e.g. utm_campaign=coffee_shop |
| utm_term | The keyword that triggered the ad display | e.g. utm_term=buy_coffee |
| utm_content | Data that helps identify a specific ad when previous parameters match | e.g. utm_content=text |
UTM tag syntax requires the “=” sign between a key and its value, and the “&” sign to separate parameters from one another. An advantage of GA4 tagging compared to Universal Analytics is that it is case-insensitive.
