How can an ArcGIS Online administrator analyze an item’s effectiveness upon reviewing its details?

The effectiveness of an item within ArcGIS Online can be comprehensively analyzed by evaluating the amount of usage information and metrics available. This analysis allows administrators to gain insights into how often the item is accessed, how it is being used, and its overall impact on users. Metrics such as view counts, shares, and interactions provide quantitative data which can inform decisions on whether to keep, revise, or retire an item.

While other answers may offer some insights — such as checking layers or user feedback — they do not provide the detailed, quantitative data that usage metrics can deliver. Assessing these metrics gives a clearer picture of the item's performance and utility in the context of organizational goals, making it a crucial tool for effective administration.
