Photo tagging is the process of identifying and labeling people, objects, or locations in a photograph. This is commonly done on social media platforms like Facebook and Instagram, where users can click on a person's face or an object to add a tag. Tags help others recognize who or what is in the photo, making it easier to connect with friends or share memories. When a photo is tagged, it often becomes linked to the tagged person's profile or a specific page. This allows others to view more information about the person or object, enhancing the social experience. Additionally, tagged photos can appear in search results, increasing visibility and engagement.
