To track website traffic you need analytics software. That anonymously logs every visitor to your site and keeps track of their actions. One of the most popular analytics apps is Google Analytics. It’s free, but there can be a learning curve in getting it set up correctly. If you don’t add your tracking code the right way, then you won’t be able to track your traffic. Consider getting an analytics expert to help you create the right setup for your website.
Not all web traffic is welcomed. Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. There is also "fake traffic", which is bot traffic generated by a third party. This type of traffic can damage a website's reputation, its visibility on Google, and overall domain authority.
