Unfortunately, not all Bitly users are using them for good reasons. Some people use them to hide nefarious links. Fortunately, there is an easy way to quickly determine what's behind a Bitly URL without actually clicking on the link. The trick is to simply 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 show you what the original link was.
You can try this trick with a URL that I recently shortened. Bit.ly/THWTAPRIL will lead you directly to a copy of the slides that I used my recent Intro to Teaching History With Technology webinar. Bit.ly/THWTAPRIL+ will lead you to the Bitly page where you can see my original presentation URL and see when I created the shortened URL.
Watch this short video to see how you can use the "+" trick to find out what's hidden behind a Bitly link.
