Understanding the setup of Google Analytics 4 (GA4) is crucial. A poorly configured GA4 can lead to unreliable data, often referred to as “garbage in, garbage out”:
Critical Importance of Setup: The insights you derive from GA4 are only as good as how it’s configured. A setup that isn’t thought through can result in data that’s misleading or just plain incorrect. Some considerations include:
Don’t Rely on Enhanced Measurement Events:
Firstly, GA4’s Enhanced Measurement claims to automatically track certain interactions like YouTube video views and form submissions, but either don’t work at all or send misleading data to GA4.
Using GTM to Create Custom Events:
Custom event tracking via Google Tag Manager (GTM) allows for the addition of detailed parameters, offering richer data.
Managing events through GTM enables precise tracking setups tailored to specific business needs, also ensuring that every tracked interaction provides valuable insights.
Reducing the Impact of Sampling and Thresholding:
GA4 applies sampling to your data, which can distort analysis, especially when dealing with large datasets.
Automated thresholding in GA4 may also limit data granularity, hiding data for small groups of users to prevent identifying individual users.
Export Raw Data to BigQuery:
For comprehensive analysis, consider exporting raw data from GA4 to BigQuery.
This bypasses GA4’s internal limitations, allowing for full data retention and detailed analysis without sampling distortions.
Customise Your Setup:
Tailor your GA4 setup, including custom channel groupings, to better align with your organisation’s marketing spend and strategies.
This customisation allows for more accurate tracking of marketing effectiveness and ensures that analytics are fully aligned with your business goals.
Actionable and Reliable Insights:
A well-configured analytics setup transforms GA4 from a simple data collection tool into a powerful analytical asset.
Ensures the reliability and applicability of your data, turning it into actionable insights rather than just numbers on a dashboard.
Remember, setting up your analytics tool correctly from the start is less about avoiding ‘garbage’ and more about securing a treasure trove of actionable data that drives informed decision-making.
