If you didn’t already know, web browsers like Chrome, Firefox and Internet Explorer include geolocation services on the backend. It works similar to GPS or geolocation on your mobile device. It identifies your local area either through your active Wi-Fi connection, IP address or network location. Once it finds this information and stores it successfully, it can be used in a number of different ways.
For example, every time you post a status update on Facebook or Twitter and it includes your location, the browser was accessing your geolocation data. Some websites even tap into this information automatically to deliver you local search results or more personalized information and news.
