What Is Conversion Rate Optimization?
Conversion rate optimization, or CRO, is the process of changing and improving a website so that more visitors take a key action. This action can be buying a product, filling out a form, signing up for a newsletter or clicking a button.
Definition
Conversion rate optimization is a set of steps used to raise the percentage of visitors who complete a chosen goal on a website or app.
The conversion rate is usually:
Number of people who convert ÷ Number of total visitors × 100
CRO tries to make this percentage higher over time.
Why Conversion Rate Optimization Matters
Conversion rate optimization is important because it helps you get more value from the visitors you already have, without always paying for more traffic.
- You get more sales or leads from the same number of visitors.
- You save money on ads and marketing.
- Visitors have a smoother and easier experience on your site.
- Your business can grow faster with less waste.
How Conversion Rate Optimization Works
CRO is usually done in small steps:
- Set a clear goal for example more sign ups, more sales, more clicks on a button.
- Measure the current conversion rate so you know your starting point.
- Study user behavior using tools like analytics, heatmaps, recordings and user feedback to see where people get stuck or leave.
- Create ideas for what to change, such as button text, colors, page layout, images or form length.
- Run tests often A B tests, where version A is the original and version B is the new design.
- Compare results and keep the version that gives a higher conversion rate.
- Repeat the process on other parts of the site.

Example of Conversion Rate Optimization
Imagine an online store where 1 out of 100 visitors buys something. The conversion rate is 1 percent.
The store runs a CRO test. They:
- Make the Buy Now button larger and a brighter color.
- Shorten the checkout form from 8 fields to 4 fields.
- Add trust signals, such as secure payment icons and reviews.
After testing, now 3 out of 100 visitors buy. The conversion rate is 3 percent. That is CRO working well.
