The Reports & Dashboards app gathers, analyzes, and synthesizes data from your realm, and configures it into logical data sets called dashboards. You can use the Reports & Dashboards portal, to review your site's sales, product, promotion, technical, traffic and other data. Each dashboard presents analytics that help you identify trends over time.
The metrics in the Reports & Dashboards can help you identify trends and modify your storefront strategies. Focus on the correlation between metrics and finite numbers such as revenue and number of orders. The overall goal of using metrics is to identify trends over time.
