## What you need to know

### How should ecommerce metrics be organized?

Organize metrics by business questions and customer stages: acquisition, engagement, conversion, merchandising, fulfillment, retention and profitability. Give each measure a definition, owner, data source and review frequency.

### What are acquisition metrics?

Acquisition metrics describe how prospective customers arrive and what it costs to attract them. Examples include qualified traffic, new customers, source, campaign, customer acquisition cost and acquisition contribution.

### What are engagement metrics?

Engagement metrics show whether visitors meaningfully interact with content and products before buying. Product views, search use, filters, product-detail depth and return visits are more useful when tied to intent.

### What are conversion metrics?

Conversion metrics measure progression toward a completed business outcome. They include product-view-to-cart, cart-to-checkout, checkout-to-purchase and overall purchase conversion rates.

### What are merchandising metrics?

Merchandising metrics evaluate how assortment, placement, categories, sorting and recommendations help customers find and choose products. Measure exposure as well as clicks, orders, margin and returns.

### What are fulfillment metrics?

Fulfillment metrics cover the period from accepted order through delivery, including processing time, on-time shipment, delivery reliability, cost, damage and exceptions. They connect operational performance to customer outcomes.

### What are retention metrics?

Retention metrics describe customer behavior after the first purchase, such as repeat purchase rate, time between orders, purchase frequency, cohort retention and contribution-based lifetime value.

### What are profitability metrics?

Profitability metrics show what remains after relevant costs, rather than how much was sold. Useful levels include product margin, order contribution, customer contribution, campaign profit and fully allocated operating profit.

### A quick store check

Place each KPI under acquisition, engagement, conversion, merchandising, fulfillment, retention or profitability and resolve duplicate definitions.

## Frequently asked questions

### Can one metric belong to two measurement groups?

Yes, but assign one primary purpose and definition so the same number is not interpreted differently across teams.

### Should profit metrics appear beside marketing metrics?

Yes. Acquisition volume without contribution or customer value can reward growth that destroys profit.
