Metrics and dimensions

What is a metric?

• A metric is a measurement
• Examples of metrics are “number of visits”, “pages viewed per visit”, and “average time on site”
• Metrics appear in scorecards and as columns in tables
• Metrics can also be graphed
• Groups of metrics are organized into tabs

What is a dimension?

• Many reports contain tables. These tables usually break out your data by a single dimension
•  Each row in the table shows the data for a different value of the dimension. For example, "City", "Browser"
• A secondary dimension lets us see data for each combination of two dimensions
