A user can create a tag on Facebook, by first tapping the teardrop-shaped icon under his status, and then typing in his location or scanning a list of locations that is automatically generated by Facebook. The user then clicks on the name that matches where he is, and then posts his status.
Some mobile Facebook users also have a Check-In option displayed on their screens when they log on. Tapping the icon pulls up a list of surrounding location using the phone's GPS. After choosing a location, users also get the option of tagging their friends in their statuses as well.
Many businesses use the Places option on Facebook to generate attention for themselves. Owners who set up Facebook pages for their businesses give users the option of tagging that page in their statuses, which gives them some free advertising when the status appears in the news feed. They can also create a specific place in the main menu for people to use when tagging.
Many home security companies and local law enforcement agencies advise users to limit how much tagging they do on Facebook and other social media platforms. When users tag themselves at specific locations, it alerts everyone on their news feeds that their homes are empty, potentially exposing themselves to thieves.
