Google has announced that it will block its goo.gl URL shortener for most users starting in April and for everyone else at the beginning of 2019. The service was launched in 2009, but the way users share content has changed significantly in recent years, Google says. Mobile devices are the primary method that most people use to get content, and the need for a URL shortener has dropped as a result.
Of course, a URL shortener is a service that takes the address of a page and shortens it to a smaller URL, in this case one containing "goo.gl". As mobile devices, apps, and web apps are now the most common method of accessing data, Google is moving goo.gl's focus to Firebase dynamic links – smart URLs that direct users to any region within a mobile app. [1
Existing users who have already created short links will do so. You can use the service until March 30, 2019, after which time it will be officially discontinued. Users can still manage short links through the console by this time, Google says. The good news is that existing goo.gl links will continue to work after the service has been discontinued.
