What is Cardinality? A short definition - NewMetrics

1 minute reading time

In databases, cardinality refers to the number of unique values or distinct count of a particular dimension or metric in a given time frame.

It is an important concept in data analysis as it helps to identify and understand user behavior and measure the performance of marketing campaigns.

A dimension with high cardinality has many unique values, while a dimension with low cardinality has fewer unique values.

Understanding the cardinality of dimensions and metrics in for example GA4 can help businesses make data-driven decisions and optimize their marketing strategies to improve user engagement and conversion rates.
