  9. Summary

Every online store is full of numbers: visits, clicks, orders, sales. But tracking everything effectively means tracking nothing. These few indicators give you a clear picture of your store’s performance and where the opportunities are.

1. Conversion rate

Conversion rate = orders ÷ visits × 100. If 2,000 people visit your store and you get 40 orders, your conversion rate is 2%. It measures how well your store persuades visitors to buy. Better images, descriptions, reviews and an easier checkout raise it directly.

2. Average order value

Average order value = total sales ÷ number of orders. Raising it is one of the easiest ways to increase profit, because you don’t need more traffic. Bundles, complementary products and free shipping above a threshold are effective levers.

3. Customer acquisition cost

CPA = marketing spend ÷ number of orders or new customers. This cost must stay below the profit an order generates. Calculate it alongside your break-even ROAS with our ROAS calculator.

4. Gross profit margin

The share of sales left after product and direct costs. Tracking it monthly reveals rising shipping or supplier costs before they eat into your profit. Calculate it per product with our profit margin calculator.

5. Cart abandonment rate

The share of customers who add products to the cart but don’t complete the purchase. Common causes: unexpected shipping costs, a long checkout or forced account creation. Abandoned-cart reminder emails recover part of these sales.

6. Repeat purchase rate

The share of customers who buy more than once. A returning customer doesn’t cost you a new ad, so they are more profitable. Good customer service, complementary products and useful emails increase this rate.

7. Return rate

A high return rate usually signals a gap between what customers expect and what they receive, meaning images or descriptions are inaccurate. Every return costs double shipping and sometimes a damaged product.

How to organize tracking

Summary

Profit = visits × conversion rate × average order value × margin − costs. Improving any one of these factors shows directly in the result. Start with your store’s weakest element; it is usually the easiest growth opportunity.
