What feature would you set up to collect company-specific data such as Member Status?
In many cases, you’ll have the option to use events, screen views, and/or a custom metric to track your most important metrics. However, custom metrics can produce more flexible and more readable custom reports and as such are a convenient way to track your most important metrics

Custom dimensions and custom metrics are like default dimensions and metrics in your Analytics account, except you create them yourself. You can use them to collect and analyze data that Analytics doesn’t automatically track.
Custom dimensions and metrics allow you to combine Analytics data with non-Analytics data, e.g. CRM data. For example:
- If you store the gender of signed-in users in a CRM system, you could combine this information with your Analytics data to see Pageviews by gender.
- If you’re a game developer, metrics like “level completions” or “high score” may be more relevant to you than pre-defined metrics like Screenviews. By tracking this data with custom metrics, you can track progress against your most important metrics in flexible and easy-to-read custom reports.
Custom dimensions can appear as primary dimensions in Custom Reports. You can also use them as Segments and secondary dimensions in standard reports.
Custom dimensions and metrics are only available for properties that have either been enabled for Universal Analytics or contain at least one app reporting view. Custom dimensions and metrics are supported by the Google Analytics SDKs for Android and iOS v2.x or higher, analytics.js, and the Measurement Protocol.
Custom dimensions and metrics require additional setup in your Analytics account and in your tracking code. Once you complete both steps of the setup, you can use them in your reports.
Limits and caveats
There are 20 indices available for different custom dimensions and 20 indices for custom metrics in each property. 360 accounts have 200 indices available for custom dimensions and 200 for custom metrics.
Custom dimensions cannot be deleted, but you can disable them. You should avoid trying to reuse custom dimensions. When you edit the name, scope, and value of a custom dimension, both the old and the new values can be paired with the either the old or the new dimension name. This conflates data in your reports in a way that cannot be accurately separated with a filter.
