Conversion rate optimization (CRO)

What is conversion rate optimization (CRO)?

Conversion Rate Optimization (CRO) is the process of improving your website or sales funnel to increase the percentage of visitors who complete a desired action, such as making a purchase, subscribing, or filling out a form. It’s a crucial part of growing your ecommerce or subscription business efficiently.

It’s a structured, data-driven method of enhancing the performance of a digital experience to boost the percentage of visitors who convert. It involves testing, user feedback, analytics, and continual improvement.

How to calculate conversion rate (CRO)?

Use this simple formula:

Conversion Rate = (Number of Conversions ÷ Total Visitors) × 100

For example, if your product page gets 2,000 visitors and 100 people buy, your conversion rate is 5%.

What are the benefits of conversion rate optimization (CRO)?

Optimizing conversions directly boosts revenue. Here’s how you benefit:

• Boosts sales and revenue without increasing traffic
• Improves user experience and site performance
• Lowers customer acquisition costs
• Reduces bounce and abandonment rates
• Strengthens customer trust and satisfaction

What is a conversion rate optimization (CRO) strategy?

A successful conversion rate optimization strategy includes:

• Use clear, compelling CTAs that are easy to find.
• Help visitors find what they need in as few clicks as possible.
• Optimize images and remove unnecessary scripts to load the website faster.
• Offer guest checkout, fewer form fields, and multiple payment options.
• Add product reviews, testimonials, and security badges to build confidence.
• Test headlines, layouts, colors, and copy to see what actually boosts results.
• Set up automated emails or ads to bring them back with reminders or offers.
• Make sure your site looks and works great on phones—most traffic comes from mobile.

Example of conversion rate optimization in action

Imagine you run an online store that gets about 5,000 visitors each month. Right now, only a small number of them — say 2% — end up buying. You decide to make a few simple changes: clearer product descriptions, a faster checkout, and a stronger call-to-action. As a result, your conversion rate doubles to 4%, and without any extra traffic, you’re making twice as many sales.
