We are very familiar with it as the icon that marks a current location or destination on digital map apps. That's why it conveys location more intuitively than text when sharing online.

Beyond just a location, it's also effective for emphasizing the "main point" or "target" of a conversation. Using it like "The key point of today's meeting is 📍 this" can visually highlight important content, and it's often used when sharing plans, like "My goal for this year 📍."
