An ecommerce analytics dashboard should include five categories of metrics: revenue and sales performance, marketing efficiency, customer behavior, inventory health, and a forward-looking projection layer. Within those five categories, the specific metrics should be limited to ones that connect directly to a decision someone makes this week. A dashboard that includes 40 metrics teaches you nothing. A dashboard that includes 12 to 15 carefully chosen metrics, updated automatically from every channel you operate on, tells you exactly where to focus and what to do. The brands that build dashboards this way review them in under 15 minutes and make better decisions than brands spending two hours with a report that covers everything and clarifies nothing.
