Understanding Metrics in Google Analytics
In Google Analytics, a "metric" is a quantitative measurement that shows how a website or digital product performs. Metrics are expressed through numbers (number values, %, $, time) in a Google Analytics report. They show you what a user did on your site, expressed in numbers. For example, the most common metric in a GA report is the “users” metric, which is a count of the number of people who visit your site.
How are Metrics Calculated?
Metrics are calculated in two basic ways:
- As overview totals where the metric is displayed as a summary statistic for your entire site, such as bounce rate or total pageviews.
- In association with one or more reporting dimensions where the metric value is qualified by selected dimension(s).
What are Dimensions and Metrics?
Every report in Analytics is made up of dimensions and metrics. Dimensions are attributes of your data. For example, the dimension City indicates the city, for example, "Paris" or "New York", from which a session originates. The dimension Page indicates the URL of a page that is viewed. Metrics are quantitative measurements. The metric Sessions is the total number of sessions. The metric Pages/Session is the average number of pages viewed per session.
Example of Metrics in a Report
Here's an example of how metrics are used in a report:
DIMENSION | METRIC | METRIC |
---|---|---|
City | Sessions | Pages/Session |
San Francisco | 5,000 | 3.74 |
Berlin | 4,000 | 4.55 |
In this table, City is the dimension, and Sessions and Pages/Session are the metrics.
