Bitly is a convenient tool for creating brief URLs to share in location of long URLs. Some individuals use Bitly to attempt to mask URLs to try to get you to click on nefarious links.
The technique is to simply add a “+” to the end of any Bitly URL. When you add the “+” the URL will redirect to Bitly rather of to whatever the original URL was. That will then show you the Bitly page on which the reduced URL is hosted and will show you what the original link was..

Ive produced a number 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.

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 attempt the very same link but add “+” to the end of it so it reads like this.
bit.ly/ 2ZZnuP2+ you will go to the Bitly page where I shortened my initial URL.
