# Item Metric¶

This object is associated with an item as an array of metrics. These metrics can offer insight to assist with decisioning such as average recent viewability, click-through rate, etc. Each metric is identified by its type, reports the value of the metric, and optionally identifies the source or vendor measuring the value.
