Conversion rate is the percentage of users who complete a desired action out of the total number of visitors or users. Common conversions include purchases, sign-ups, downloads, or any other goal that indicates user engagement or revenue.

Conversion rate optimization is fundamental to growth. Small improvements in conversion can dramatically impact revenue without increasing traffic or spending.

Calculating Conversion Rate: Conversion Rate = (Conversions / Total Visitors) × 100

Example: 50 purchases / 1,000 visitors = 5% conversion rate

Types of Conversions: - Macro Conversions: Primary goals (purchase, subscription) - Micro Conversions: Secondary actions (email signup, add to cart)

Benchmark Conversion Rates: - E-commerce: 2-4% average - SaaS free trial to paid: 2-5% - Landing pages: 2-11% - Email click-through: 2-5%
