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 exact 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.

Bitly is a convenient tool for creating short URLs to share in place of long URLs. Some people use Bitly to attempt to mask URLs to attempt to get you to click on dubious links.
The trick is to simply add a “+” to the end of any Bitly URL. When you include the “+” the URL will redirect to Bitly instead of to whatever the initial URL was. That will then reveal you the Bitly page on which the reduced URL is hosted and will show you what the initial link was..

Ive developed a number of short video presentations 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.
