Bitly is a hassle-free tool for creating short URLs to share in location of long URLs. Some people utilize Bitly to try to mask URLs to attempt to get you to click on nefarious links.
The trick is to simply add a “+” to the end of any Bitly URL. When you include the “+” the URL will reroute to Bitly rather of to whatever the original URL was. That will then show you the Bitly page on which the shortened URL is hosted and will show you what the initial link was..

Ive created a couple of short video demonstrations of how this trick works. This is the Instagram video that I made about it. This is the YouTube video that I made about it.

You can try 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 however include “+” to the end of it so it checks out like this.
bit.ly/ 2ZZnuP2+ you will go to the Bitly page where I reduced my initial URL.
