SH.SG - A Singapore based, full-featured URL Shortener that supports custom aliases, link expiration, password protection, geotargeting, device targeting, pixels, parameters, analytics and more! A URL shortener is a website or a program that allows a user to make long web addresses shorter. The shortened version of the address is known as a short URL. URL shorteners can be either free or paid, and can be accessed from any device with an internet connection. URL shorteners are a way to create shorter web addresses that can be used to direct people to a certain web page. One good reason to use a URL shortener is that it ensures the link will always go to the correct page. This is important because if a user sends out a URL from a shortened link and someone tries to access the content, they will always be redirected to the correct destination.
