p.p.s. Google announced today that they are shutting down their link shortener service goo.gl. From 2025, goo.gl shortened links will no longer work:

This is why link shorteners cause link rot, because eventually link shortener services close down, even ones run by megacorporations, and all their links break.
Your link will survive a lot longer if you avoid using shorteners. You don't need shorteners on Mastodon, all links count as 23 characters anyway.
