Conversion Rate
Conversion Rate (CR) is the conversion coefficient that shows the percentage of users who completed a target action: a purchase, form submission, call, subscription, registration, or any other business result. It is one of the key performance indicators for a website, advertising, and marketing.
What is Conversion Rate?
Conversion Rate (CR) is a metric that shows the proportion of visitors who completed a desired action that the business considers a conversion.
A conversion can be:
- Purchase
- Form submission
- Phone call
- Subscription
- Download
- Registration
- Adding to cart
- Visiting a specific page
Example:
Out of 1,000 website visitors, 50 placed an order → Conversion Rate = 5%.
Formula for calculating Conversion Rate
CR = (Number of Conversions / Number of Visits) × 100%
Example:
- Visitors: 2,000
- Conversions: 80
80 ÷ 2000 × 100 = 4%
Types of conversions
- Micro-conversions
Intermediate actions:- Viewing a product page
- Adding to cart
- Clicking on a CTA
- Watching a video
- Macro-conversions
Primary business goals:- Purchase
- Subscription
- Form submission
- Payment

CR helps:
- Evaluate the effectiveness of advertising campaigns

A high CR = lower customer acquisition cost → higher ROI.
