Conversion Rate is the percentage of website visitors who complete a desired action (conversion). It is calculated by dividing the number of conversions by the total number of visitors and multiplying by 100.

Common types of conversions include:

• Purchases: Completing a sale on an e-commerce site
• Lead generation: Filling out a contact form
• Subscriptions: Signing up for a newsletter or service
• Downloads: Downloading a resource or app

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

A good conversion rate varies by industry, but typically ranges from 2-5% for websites.
