4 Key KPIs for CRO

1. New Users vs. Returning Users

The primary factor to consider is analyzing the new vs. returning users. You need to calculate the users every month to determine how many users are coming to your website repeatedly. If people are not coming to your website, it means there is something wrong with your website. For example, your content is not engaging, your website is not user-friendly, design is not attention-grabbing.

So, let’s say you are getting thousands of users in a month, but less than 5% of users are coming to your website, and that too for a few seconds. Now that sounds problematic. Because you are getting less than 5% retention and no user is converting.

That’s with CRO, you will be able to come up with a percentage or a number that will help you determine new and returning visitors. Remember to increase the percentage of your returning visitors.

2. Bounce Rate

People who leave your website without taking action come under the bounce rate. Bounce rate is measured from the inaction of the users, users who scroll through your website without doing anything, are considered bounced users. If that happens often to your website, it means your content or the offering is not good enough, you need to revamp or redesign your website and test the bounce rate again. Harness the power of professional website redesign services to strategically enhance your site, fostering user engagement and minimizing bounce rates.

Since bounce rate is an important factor for CRO and helps businesses to make proper changes before launching the website.

3. Cost Per Conversion - CPC

Your website users are converting but at what cost? This is one of the essential questions to ask when it comes to executing conversion campaigns.

This type of KPIs will help you calculate campaign ROI, enabling you for new tactics or at the very least help you in making important decisions to perform proper adjustments.

Let’s take an example to understand this. While performing ads your CPC might be high since, you spend a lot on ads but didn’t get many conversions, which means your investment in marketing was not fruitful and didn’t generate any ROI).

The reason could be anything, it may be visitors bouncing from your website without converting meaning, your investment has resulted into a waste.

An easy-to-navigate website plays an important role when you are out looking for clients. The easy navigation and overall usability are extremely important factors to consider.

Another important aspect is the mobile responsiveness of the website. Since, the majority of the website users are mobile users, if the website is mobile-friendly, the conversion chances will surely increase.

2. Crispy Content

4. Engaging Call to Action Button
