Of course, you have used more than one URL shortener, but goo.gl is one of the most famous URL shortening tools over the Internet, but it will end next year. As it has been confirmed that Google will permanently abandon this service.
Additionally there is a possibility that goo .gl data will be exported. Currently, the US company offers suggestions to users of other pages that can be used to shorten URLs.
Those options are: Bitly, Ow.ly, or Firebase.
so after 10 years of work and with milions of customers and shortlinks every one is confused what is the next shortner to use?.......
