Definition:
Custom dimensions are like the default dimensions in the web analytics tool, except that they are created by the analyst to study dimensions of his or her choice. These dimensions can be used to collect and analyze data that web analytics tools do not automatically follow, such as CRM data, phone calls, data about users who register…
Custom dimension in Google Analytics
In Google Analytics 4, custom dimensions can be created to capture additional information that is not available by default. These dimensions can be applied at the user, event or session level, allowing for detailed and meaningful categorization of data. This is especially useful for answering specific business questions and gaining deeper insights. Unlike previous versions, GA4 does not set a fixed limit on the number of custom dimensions that can be created, but it is important to manage these dimensions efficiently to maximize their usefulness. Custom dimensions in GA4 can be used in custom reports and scans, allowing analysts to drill down into the data and discover patterns of user behavior. In addition, custom dimensions in GA4 can be used as filters to segment data, enabling more granular and targeted analysis. This makes it easier to identify trends and make informed decisions based on accurate and relevant data.
Objectives
Custom dimensions and metrics allow data from the web analytics tool to be combined with other data such as CRM data. For example, if the gender of users of a CRM is recorded, it can be combined with Analytics data to see which pages each person has viewed according to their gender. These custom dimensions can be displayed as primary dimensions in custom reports. They can also be used as dimensions and child segments in standard reports.
