\"CustomDefinition:<\/strong><\/p>\n

A custom metric<\/strong> is a quantitative measure configured in an analytics tool to analyse data that is not covered by its predefined metrics. In Google Analytics 4 (GA4), it allows numerical values sent through event parameters to be used.<\/p>\n

These metrics help analyse business-specific results and can incorporate information from other systems, such as a CRM, when an integration sends it to Analytics. Creating a metric does not establish that connection or automatically start data collection.<\/p>\n\n

Creating a custom metric<\/h2>\n

In GA4, custom metrics are event-scoped. Before registering one, the transmission of a numerical parameter from the website, application or relevant integration must be configured, and its receipt by Analytics must be checked.<\/p>\n

Creating a custom metric requires the Editor or Administrator role on the property. The process consists of these steps:<\/p>\n

    \n
  1. Select the property:<\/strong> open the GA4 property receiving the data.<\/li>\n
  2. Open custom definitions:<\/strong> in Admin, go to Data display and select "Custom definitions".<\/li>\n
  3. Start creating the metric:<\/strong> open the "Custom metrics" tab and click "Create custom metric".<\/li>\n
  4. Assign a name:<\/strong> use a clear, unique name that identifies the measure in reports. A description can be added to explain what it represents.<\/li>\n
  5. Specify the event parameter:<\/strong> enter the name of the numerical parameter being sent. It must match the name used in the implementation.<\/li>\n
  6. Choose the unit of measurement:<\/strong> select the unit corresponding to the data, such as standard, currency, distance or time. For monetary metrics, also specify whether they represent costs or revenue.<\/li>\n
  7. Save the configuration:<\/strong> once the data has been sent and the metric created, it usually takes between 24 and 48 hours to become available in reports.<\/li>\n<\/ol>\n

    The unit must correspond to the value being sent. If a duration is recorded in milliseconds, it should not be configured as seconds without the appropriate conversion.<\/p>\n

    Standard properties allow up to 50 custom metrics, and Analytics 360 properties allow up to 125. Before registering a new one, it is useful to check whether a predefined metric already meets the need. The full procedure is available in the GA4 custom metrics documentation<\/a>.<\/p>\n
