PPC or online advertising can be tracked via the PPC platforms and web analytics platforms to ensure there are enough good quality leads or high enough sales for the money spent (known as return on investment or return on ad spend).

The PPC Platforms I have used previously include Google Ads and Bing Ads as well as other social media advertising platforms such as Meta. There are several web analytics tools that can be used to track PPC, for example Google Analytics 4.
