Dimensions are attributes of your data. The dimension Page indicates the URL of a page that is viewed. Dimensions are used to categorize and organize the data, while metrics are used to measure and track the performance.
Dimensions are attributes or characteristics that describe your data. They are uses to categorize and organize the data.
Dimensions are typically Non-Numeric values, such as:
- Page Title
- City
- Device
- Source
- Campaign
Metrics are quantitative measurements that provide insight into your data. They are used to track and measure the performance of your website or App.
Metrics are typically Number Values Such As
- Sessions
- Views
- Event Counts
- Engagement Rate
- Conversion Rate
Not every metric can be combined with every dimension. Each dimension and metric has a scope: user-level, session-level, or hit-level. In most cases, it only makes sense to combine dimensions and metrics that share the same scope. For example, Sessions is a session-based metric so it can only be used with session-level dimensions like Source or City. It would not be logical to combine Sessions with a hit-level dimension like Page.
Metrics calculation is also affected by stacking more than one dimension with a given metric. In both the preformatted and custom reports, you can use multiple dimensions together.
