About a year ago, Google announced they would be shutting down their URL shortener service March 30, 2019. Goo.gl has been around since 2009. This is unfortunate because so many people rely on goo.gl for creating short links. Bit.ly is a good choice if you need to shorten a few URLs, but once you go over the free plan (10,000 a month), you have to upgrade to their enterprise edition which cost around $1,000 a month.
Fortunately, there are a few free options such as t.ly, tinyurl, is.gd, to.ly, and cutt.ly. Also, there are extensions such as Link Shortener, that allow you to shorten links in one click using multiple different shorteners. If you have a need to shorten URLs, give Link Shortener a try!
