"Tracking" in the field of web design refers to the measurement and recording of visitor behaviour on a website. It enables website operators to collect data on how visitors interact with the website, which pages they visit, how long they stay on a page and what actions they perform.

One example of tracking is the use of analytics tools such as Google Analytics. These tools can be installed to collect information about the number of visitors, the origin of the visitors, the most popular pages and the length of stay. With this data, website operators can understand how their website is used and which content or functions are particularly successful.

Matomo is an open source analytics tool that offers similar features to Google Analytics. It allows website operators to host their data themselves and thus offers more control over the data collected and the data protection guidelines.

Another example of tracking is the recording of conversions. If there is a goal on a website, such as the purchase of a product or the completion of a contact form, tracking can help to measure the number of conversions. It is possible to determine how many visitors actually reach the goal and which steps lead to a conversion.

Tracking enables website operators to gain insights into visitor behaviour, optimise their website, improve the user experience and make business decisions. However, it is important to use tracking responsibly and in accordance with data protection regulations in order to protect the privacy of visitors.
