Bitly is a hassle-free tool for producing short URLs to share in place of long URLs. Some people utilize Bitly to attempt to mask URLs to attempt to get you to click on dubious links.
The trick is to just add a “+” to the end of any Bitly URL. When you add the “+” the URL will redirect to Bitly instead of to whatever the original URL was. That will then show you the Bitly page on which the shortened URL is hosted and will reveal you what the initial link was..

You can attempt this with my Bitly link of.
bit.ly/ 2ZZnuP2 which will take you to the registration page for my Practical Ed Tech Newsletter (.
https://practicaledtech.com/weekly-newsletter/). If you try the same link however include “+” to the end of it so it reads like this.
bit.ly/ 2ZZnuP2+ you will go to the Bitly page where I reduced my initial URL.

Ive created a couple of brief video presentations of how this technique works. This is the Instagram video that I made about it. This is the YouTube video that I made about it.
