What is Conversion Rate Optimization (CRO)?
CRO is the systematic process of increasing the percentage of website visitors who complete a desired action (purchasing a product, signing up, adding to cart).
Conversion Rate = (Number of Purchases ÷ Total Visitors) × 100
Example: 50 purchases from 2,000 visitors = 2.5% conversion rateAverage E-commerce Conversion Rates by Industry (2025)

|---|---|---|
| Food & Beverage | 4.5-6% | 8-10% |
| Health & Beauty | 3.5-5% | 7-9% |
| Fashion & Apparel | 2.5-4% | 5-7% |
| Electronics | 1.5-3% | 4-6% |
| Home & Garden | 2-3.5% | 5-7% |
