Deprecation of Custom-Parameter Reporting in Google Analytics
In Google Analytics, custom-parameter reporting is no longer in use. Previously, individual events required the identification of parameters, leading to the creation of multiple custom dimensions and metrics. However, with the deprecation of custom-parameter reporting, the focus has shifted to property-wide identification of dimensions and metrics. This enhancement allows you to create a single dimension or metric based on a parameter and report on it for multiple events. The change simplifies the setup of custom dimensions and metrics while improving data processing.
Custom-Parameter Reporting versus Property-Wide Reporting
In the past, custom dimensions and metrics were associated with specific parameters tied to individual events. This meant creating multiple custom dimensions and metrics to account for different event parameters. However, Google Analytics now allows you to identify dimensions and metrics at the property level, rather than on a per-event basis. This property-wide approach enables you to define a single dimension or metric based on a parameter and apply it to multiple events within your property. As a result, you can streamline your reporting and analysis process while still capturing granular data points.
Benefits of Property-Wide Reporting
Adopting property-wide reporting for custom dimensions and metrics offers several advantages:
- Simplified Setup: With property-wide reporting, you only need to define a dimension or metric once for a parameter. This eliminates the need to create multiple custom dimensions or metrics for different events with the same parameter.
- Consistent Analysis: By having a single dimension or metric tied to a parameter, you can analyze and compare the data across multiple events. This ensures consistency in your reporting and makes it easier to identify trends and patterns.
- Efficient Data Processing: Property-wide reporting reduces the processing overhead associated with custom dimensions and metrics. It allows Google Analytics to optimize data handling and storage, resulting in faster and more efficient analysis.
Transitioning to Property-Wide Reporting
If you were previously using custom-parameter reporting, transitioning to property-wide reporting is straightforward. Simply identify the parameters you want to create dimensions or metrics for and define them at the property level in your Google Analytics account. Once set up, you can start utilizing these dimensions and metrics across multiple events without the need for additional setup or configuration.
Example Use Case: Property-Wide Custom Dimension
Let’s consider an example where you want to track the source of traffic to your website. With custom-parameter reporting, you would have needed to create a separate custom dimension for each event that captures the source parameter. However, with property-wide reporting, you can create a single custom dimension called “Traffic Source” and apply it to various events, such as pageviews, button clicks, and form submissions. This allows you to analyze the traffic source across different user interactions without the need for redundant dimensions.
Custom-Parameter Reporting versus Property-Wide Reporting
| Custom-Parameter Reporting | Property-Wide Reporting |
|---|---|
| Multiple custom dimensions and metrics for each event parameter. | A single custom dimension or metric tied to a parameter at the property level. |
| Complex setup and management of custom dimensions and metrics. | Simplified setup and consistent application of dimensions and metrics. |
| Potential for redundant and unnecessary custom dimensions. | Elimination of redundant dimensions and streamlined reporting. |
