Data AnalyticsData Visualisation

Effective data analysis is critical to achieving business success. GA4 reporting surfaces provide the necessary tools to collect, analyse, and visualise data. These surfaces help companies understand user behaviour and track performance metrics, aiding in strategic decision-making.

To fully utilise these tools, it’s essential to understand what GA4 reporting surfaces encompass. Let’s begin with an overview of these surfaces and their functionalities.

What are GA4 Reporting Surfaces?

GA4 reporting surfaces are how companies collect, analyse, and visualise data within Google Analytics and through third-party integrations. Reporting surfaces provide various tools and interfaces for creating reports, exploring data, and customising visualisations. Companies use these surfaces to gain insights into user behaviour, track performance metrics, and make data-driven decisions.

What Reporting Surfaces Does GA4 Support?

GA4 offers three reporting surface types:

  • Reports, Insights, & Explorations: GA4’s standard reporting capability available to every user within Google Analytics.

  • Google Analytics Data API: Provides access to third-party data visualisation tools like Looker Studio.

Choosing the Google Analytics Data API over standard and exploration reports provides unmatched flexibility and depth. It suits businesses looking for detailed, customised reporting solutions integrating data from multiple sources.

How to Choose the Right GA4 Reporting Surface

Here’s a step-by-step framework to help you choose the ideal reporting surface for your Google Analytics 4 data needs. 

Step 1: Define your reporting goals

First, define your reporting goals; what questions are you trying to answer with your data? (user acquisition, campaign performance, user behaviour)? 

How deep do you need to dive (high-level overview or detailed user journeys)? Consider combining GA4 data with other sources like CRM or marketing automation platforms. This initial goal definition will guide your selection process.

Step 2: Assess your technical expertise

Understanding your team’s expertise and limitations is essential, as this will define the labour and resources required to answer the questions and meet the goals outlined in step one.

For example:

  • Are you comfortable with basic data analysis techniques and filtering data?

  • Do you have experience with coding or querying databases?

Data integrity is vital for developing accurate, reliable insights. If you cannot work with data effectively, it’s best to use GA4’s standard reporting or exploration—meaning you’re restricted to only analysing GA4 data.

If this doesn’t align with the goals you’ve set out in step one, consider hiring data analytics experts to set up advanced reporting and dashboards, combining your various data sources, including Google Analytics.

Step 3: Consider your data volume and complexity

Data volume and complexity are crucial in choosing the right GA4 reporting surface. Here’s why:

Data Volume: The amount of data you collect in GA4 impacts the performance and efficiency of different reporting options.

  • Smaller data sets (thousands of events): Basic reporting surfaces like Reports & Explorations can efficiently handle smaller datasets. They provide a quick overview without requiring complex tools.

  • Larger data sets (millions of events): For larger datasets, it’s better to use a more advanced option like Looker Studio or BigQuery, specifically designed to handle massive data volumes and enable faster analysis.

Data Complexity refers to the intricacy of user interactions you want to analyse.

  • Simple User Journeys: If your analysis focuses on basic user actions (e.g., page views, purchases), Reports & Explorations might suffice.

  • Complex User Journeys: To analyse intricate user journeys with multiple interactions (e.g., abandoned carts, specific product usage), consider options like Looker Studio or BigQuery. These tools allow more advanced analysis and filtering to understand complex user behaviour.

By understanding your data volume and complexity, you can choose a reporting surface that efficiently handles your data and allows you to analyse it at the desired level of detail. Remember, simpler tools suit smaller, less complex data sets, while more powerful options are necessary for large, intricate datasets.

Step 4: Evaluate your reporting needs

The functionalities you require in your reports will significantly impact your choice of reporting surface. Here’s a breakdown of key considerations:

Pre-built reports vs. customised dashboards:

  • Pre-built reports: These are readily available reports within GA4. They offer a quick overview of essential metrics and are suitable for basic needs but offer limited customisation.

  • Customised dashboards: If you need to tailor reports to your needs, consider options like Looker Studio or BigQuery. These advanced options let you build visually appealing and highly customised dashboards that showcase the data most relevant to you.

Data visualisation, filtering, and drill-down:

  • Data visualisation: Do you need basic charts or more advanced visualisations to communicate insights effectively? Looker Studio offers a broader range of interactive charts and graphs for impactful data presentation.

  • Filtering and drill-down: How important is filtering data and deep-diving into specific segments for further analysis? Advanced options like Looker Studio and BigQuery provide powerful filtering and drill-down capabilities to explore individual data points in greater detail

Collaboration:

  • Sharing reports: Do you need to share reports with your team and collaborate on insights? Looker Studio’s real-time collaboration allows you to collaborate on reports and share findings efficiently.

Evaluating your reporting needs can help you determine the required customisation, data visualisation, and collaboration features. Pre-built reports and basic tools may suffice for simple needs, while more advanced options offer extensive customisation and functionalities for in-depth analysis and team collaboration.

Step 5: Choose the right reporting surface

Based on your answers to the previous steps, consider the following options:

  • Reports & explorations: Great for basic reporting needs with pre-built reports and fundamental exploration functionalities—easy to use, but limited customisation and confined to GA4 data only.

  • Google Analytics Data API: Ideal for developers with coding expertise who need maximum flexibility and programmatic access to GA4 data for custom reports or integration with other tools. Requires technical knowledge and data analytics expertise.

  • BigQuery: A powerful data warehouse for storing and analysing large GA4 datasets alongside data from other sources. It enables complex analysis with SQL queries but requires technical expertise and potentially high costs for large datasets.

  • Looker Studio Integrates well with all the above and offers a user-friendly interface for building comprehensive dashboards. It connects to various data sources (GA4 reports, Data API, and BigQuery) for holistic reporting and complex visualisations. Depending on the plan, it may have a learning curve and potential data limitations.

Step 6: Choosing Looker Studio as a central data hub

For most clients, we recommend using Looker Studio as a central hub for your GA4 reporting, regardless of their chosen initial reporting surface. Here’s why:

  • Connects to various data sources: Looker Studio can seamlessly integrate with Reports & Explorations, data extracted via the Data API, and data residing in BigQuery for a holistic view of your data from multiple sources.

  • User-friendly interface: Building visually appealing and interactive dashboards is more accessible with Looker Studio’s drag-and-drop functionalities, even without extensive coding knowledge.

  • Customisation and flexibility: Looker Studio offers greater customisation compared to Reports & Explorations and allows for more interactive visualisations than BigQuery alone.

  • Collaboration: Share and collaborate on reports with your team in real time using Looker Studio’s collaboration features.
