E‑commerce performance metrics are quantifiable indicators—such as conversion rate, average order value (AOV), cart abandonment rate, and customer lifetime value (CLV)—used to evaluate the health and growth of your online store. These metrics help identify opportunities, prioritize optimization, and understand the effectiveness of your funnels and marketing efforts.

- Improve ROI on traffic: Knowing AOV and conversion rates helps ensure paid traffic delivers value.
- Prioritize improvements: Areas with high drop-off receive immediate focus for UX or messaging adjustments.
- Support revenue planning: Insights into CLV, average order, and funnel velocity enable better forecasting.
