As the name suggests, geotagging involves “tagging” a geographical location to something like a status update, a tweet, a photo, or anything else you post online. It’s especially useful because many people now share content on their favorite social networks via their smartphones or tablets while on the go, so they’re not always in one specific location like they used to be when we could only access the web from a desktop computer.

Geotagging a location to your posts gives your friends and followers a deeper insight into where you are and what you’re doing. For example, if you’re tweeting about a restaurant experience downtown, you can tag that restaurant location to your post to let everyone know exactly where you are so they know to visit (or even avoid, depending on what you share about it). Or if you’re posting photos while on vacation, you can tag the specific hotel, resort, or other location to give people a sense of the places you’re visiting.

Most major social networks now have geotagging features built into both their web versions and their mobile apps. Here are some quick tips on how to use them.

When you make a status update or other media post on Facebook, you should see a small location pin icon that you can click to “check in” to a place. Use the dropdown menu to choose a nearby place or search for a specific place. Your location will be posted next to your Facebook post.
