What tool can be used on Facebook for reading and analyzing metrics?

Insights is the designated tool on Facebook specifically designed for reading and analyzing metrics related to your Facebook Page's performance, ad campaigns, and audience engagement. It provides detailed analytics that help users track the effectiveness of their content and advertising strategies. With Insights, users can view various metrics such as reach, engagement, impressions, and audience demographics, allowing for informed decisions to enhance their marketing efforts.

The other choices, while they sound relevant, do not specifically refer to the established tool on Facebook for this purpose. Analytics is a broader term that can encompass various types of data gathering and analysis across different platforms, and Reports generally refer to documents generated from data collected, but they lack the embedded analytical capabilities that Insight provides. The Metrics Dashboard may suggest a similar function but does not specifically correlate with Facebook's tools as officially defined.
