A master tag is a specific keyword or phrase that is used to categorize and organize content on a website or social media platform. It serves as a label that helps users easily find and navigate through related content. Unlike regular tags, a master tag is carefully chosen and consistently used to represent a broad topic or theme, making it a powerful tool for content creators and marketers to reach their target audience. With its ability to group and connect diverse content, a master tag is a crucial element in creating a cohesive and effective online presence.
