3Quick Read
Conversion Rate Optimization (CRO), or in other words, increasing the conversion rate, is all about boosting your conversion rate! To achieve this increase, you make changes to your website, such as adjusting the text, design, colors, and then measure the impact of these changes using tools like A/B testing and heatmaps to see how effective they are. Let's dive in and understand what conversion and conversion rate mean so we can work on increasing them.
What is Conversion?
Conversion is the action you want your Website/E-shop visitor to take. And by action, we mean anything that turns your site's casual viewer into an active User (newsletter) or, even better, into your Customer.
Example: For a website, conversion can be signing up for the newsletter or sending a message through a form. For an E-shop, it is buying a product.
What is the Conversion Rate?
The Conversion Rate is the number of conversions divided by the total number of visitors to your website.
How do we measure the Conversion Rate?
We measure the Conversion Rate as a percentage. To find it, divide the number of visitors to your site (total traffic) by the number of conversions, and multiply the resulting number by 100.
Example: 100 people visit your e-shop, and 5 of them make a purchase, so your Conversion Rate is 5%.

How do we do Conversion Rate Optimization (CRO)?
To perform Conversion Rate Optimization (CRO for short), we use A/B testing tools, Heatmaps, and Google Analytics. With the data collected, we optimize our Landing Page or our E-shop. Some of the optimizations we make are as follows.
Branding and Consistency
Maintaining consistent branding everywhere increases CRO because your customer knows what to expect from you. Optimize your ads based on your brand, as well as all the CTAs you use.
UX and UI Design Optimization
Changes in UX (user experience) design play a huge role in conversion.
Keep in mind that good UX design should be:
Useful
User-friendly
Accessible
Reliable
Functional
Desirable
Valuable
Also, changes in UI (user interface) design increase the Conversion Rate.
Very small changes in content, titles, and colors can make a difference.

5 Benefits of Conversion Rate Optimization
Here are the main benefits of Conversion Rate Optimization, because there are many more. To understand how important CRO is, think about the psychology studies conducted by social media.
Increases Sales
100 visitors entered your E-shop, and 4 purchased. With CRO, 100 visitors will still come in, but 6 or 10 will buy.
Reduces Bounce Rate
The bounce rate is the rate at which users enter your website and then leave (bounce). In a simple example with time to understand it easily (bounce rate doesn't measure time, though).
Again, those 100 visitors enter, and leave in 10 seconds. Conversion Rate Optimization keeps them on your site for another 20 seconds, thus reducing the bounce rate.
Measures Everything
With CRO, you don't have to guess; it measures everything. You use A/B testing and heatmaps to see what's not working correctly and optimize it.
