The Nightmare of GA4 Referrals

In today's digital landscape, data is everything. Businesses rely on analytics platforms to track and understand user behavior, optimize campaigns, and make informed decisions. Universal Analytics has been a trusted tool for many marketers, providing valuable insights into Website traffic and referral sources. However, with the introduction of GA4, a new nightmare has emerged – the issue of self-referrals.

Introduction

Moving into a new house can be exciting, but it can also be filled with unexpected surprises. Similarly, transitioning to a new data-driven platform like GA4 can come with its own set of nightmares. One particular horror story begins with someone moving into a new house, or in this case, a new subdomain. The nightmare revolves around the mishandling of referrals in GA4, causing confusion and frustration for marketers and business owners.

Understanding Universal Analytics and GA4

Before diving into the nightmare of GA4 referrals, let's take a moment to understand the difference between Universal Analytics and GA4. Universal Analytics has been the go-to analytics platform for many years, offering a comprehensive set of features and capabilities. It tracks user behavior, measures conversions, and provides in-depth reports on traffic sources, audience demographics, and more.

GA4, on the other HAND, is the next generation of analytics from Google. It aims to provide a more holistic view of customer interactions across various platforms and devices. With GA4, businesses can track user interactions within websites, apps, and even offline events. It offers real-time data analysis, machine learning capabilities, and advanced tracking mechanisms.

The Issue with Self-Referrals in GA4

In the realm of analytics, a self-referral occurs when a visitor navigates from one page or subdomain of a website to another page within the same domain. In Universal Analytics, self-referrals were identified as such, allowing marketers to differentiate them from external referrals. However, in GA4, things work a bit differently.

In GA4, when a visitor navigates from a subdomain to the main domain, GA4 no longer recognizes it as a referral from a separate domain. It automatically ignores the referrer, bundling the visit into the "not set" bucket or unassigned traffic. This poses a significant challenge for businesses that rely on tracking and attributing referrals accurately.

The Silent Nightmare of Unassigned Traffic

The nightmare intensifies when businesses realize that GA4 silently assigns the unassigned traffic to the default Channel grouping of "direct/none." This means that the traffic from subdomains that used to be easily identified in Universal Analytics now gets lost in the sea of unattributed traffic. This can lead to significant problems in tracking and reporting, as marketers are unable to accurately measure the impact of their marketing efforts.

The Impact on Tracking and Attribution

Before the arrival of GA4, marketers could easily identify traffic coming from specific subdomains, enabling them to attribute conversions and optimize campaigns effectively. However, with GA4's handling of self-referrals, this becomes a challenging task. The nightmare Scenario arises when a marketing agency creates multiple subdomains on behalf of a business and drives paid traffic to those subdomains. Previously, the business could attribute all the traffic coming from those subdomains accurately. Now, they are left with a mountain of "not set" traffic, making it impossible to gauge the effectiveness of their campaigns.

Identifying and Fixing the Problem

Fixing the nightmare of GA4 referrals requires a proactive approach. The first step is to identify whether your website is affected by this issue or not. Exploration reports come in handy for this purpose. By creating a blank report, importing the page referral dimension, and using entrances as a metric, you can assess the impact of unassigned traffic on your site. Setting up a filter to include only your domain's page referrals ensures accurate results.

Using Exploration Reports to Assess the Issue

Exploration reports provide valuable insights into the extent of the nightmare. By populating the report and filtering for referrals that contain your brand or domain name, you can determine the number of unassigned entrances in a given time period. This report allows you to compare the data with the original referral report and observe the discrepancy caused by GA4's handling of self-referrals.

Creating Filters to Determine Referrals

To get to the root of the problem, it's essential to explore hostnames. By importing hostname as a dimension and filtering out hostnames that contain the subdomain causing the issue, You can identify the exact host that is receiving the traffic. Additionally, filtering source medium to only display data Revenue/referral ensures that you are examining the correct source of the self-referrals.

Exploring Hostnames to Uncover the Culprit

Delving deeper into the exploration reports can involve adding landing pages as Dimensions to pinpoint the specific pages receiving the self-referrals. However, privacy concerns may limit the extent to which you can explore this aspect. Structuring your exploration with hostname as a dimension and entrances as a metric is crucial to unravelling the mysterious self-referrals.

Conclusion

The nightmare of GA4 referrals is a perplexing challenge for businesses relying on accurate tracking and attribution. The shift in how GA4 handles self-referrals has caused unassigned traffic to go unnoticed, leading to a loss of valuable insights and measurement of marketing efforts. By utilizing exploration reports, creating filters, and diving into hostnames, businesses can shed light on the issue and take steps towards reclaiming the accuracy and effectiveness of their analytics.
