What is Custom Dimensions in Google Analytics?
Custom dimensions allow you to create an additional dept of customized tracking that Google Analytics doesn’t automatically track for you. Think of it as adding a custom “dimension” where you can create a space to collect and analyze your custom data within Google Analytics.
For example, you can create a custom dimension that uses a javascript variable to collect and track your e-commerce shopping cart transaction values. Setting this dimension up will allow you to more accurately track your e-commerce analytics. Every time you have conversion you can accurately record the total transaction value and pass this information along to Google Analytics using custom dimensions.
