Web Beacons are small, transparent images embedded in web pages or emails that help track user behavior. They are often used by marketers to gather data on how users interact with content, such as whether an email was opened or a webpage was visited. This information helps companies understand the effectiveness of their campaigns. These beacons work by sending information back to the server when the image is loaded. Although they are useful for analytics, Web Beacons can raise privacy concerns, as users may not always be aware that their actions are being monitored.
