CRO stands for Conversion Rate Optimisation. This term stands for the various activities involved in optimising a website in order to increase the conversion rate. These changes are related to user experience, i.e. trying to make the website more user-friendly and successful. It is also related to website testing, such as A/B testing, which examines which form of website is more appealing to the customer. Another method can be audience research, which aims to get to know your target audience so that marketers can tailor their campaigns and online sales.
