web beacons

Web beacons are tiny, invisible images or scripts embedded on websites or emails used to track user behavior. When a user opens a webpage or email containing a web beacon, it sends a signal back to the server, revealing information like whether the content was viewed, when, and from what device or location. They help website owners analyze visitor engagement, improve user experience, and measure the effectiveness of marketing campaigns. While useful for analytics, web beacons raise privacy concerns because they can collect data without explicit user awareness or consent.
