What feature is required to collect the number of comments users posted to a web page?
- Custom Dimension
- Calculated Metric
- Custom Channel Groupings
- Custom Metric (Correct Answer)
The Custom Metric feature is what you need to gather the amount of comments that users post to your (or your clients’) webpage.
Explanation
Metrics (not dimensions) track quantitative data – in this case, the number of user comments.
But since Google Analytics’ most common metrics (i.e., events and views) don’t help you track every metric, the example above demands that you use a custom metric. Custom metrics are more flexible and allow you to track countless data types.
In another example, Google Analytics Help discusses how a gaming website can also use custom metrics to track when users complete a level. Custom metrics can sift out screens views and specific actions without “double counting,” allowing you to arrive at the desired metric.
