How does a location tracker by link actually work?

According to a study published in the Journal of Cyber Security Technology, location tracking via link typically requires the recipient to click on the link and grant permissions, allowing the tracker to access their device’s location services (1). Research suggests that the accuracy of link-based location tracking can be limited compared to installed monitoring apps, with a study by the International Journal of Digital Crime and Forensics finding that link-based methods can be affected by various factors, including device type and operating system (2).
