Call tracking is a system used to track incoming phone calls and measure the effectiveness of marketing campaigns. The system captures the source of each incoming call, such as a website, search engine, or advertisement, and records the caller’s information, such as their number and location, so that businesses can measure the ROI of their campaigns. Call tracking also helps businesses improve customer service by providing insights into customer preferences, such as the time of day they prefer to be contacted, as well as the types of products and services they are interested in.
