As of today Instagram is adding three new features to Stories which allows you to use URL links, tag friends and use Boomerangs in Stories.
URL Links in Stories
Verified Instagram Users have the ability to add links directly in their Stories posts. The link itself appears as a See More text link but they will be able to send Users directly to pages of their choices anywhere without Instagram Users ever leaving the app.
All Instagram Users can now add up to 10 Mentions at a time to their Stories. This can be done by simply using the add text feature and including the @ symbol and the Usernames.
Boomerang is a standalone app that allows Users the ability to create 1 second video loops that use to need to be created first in Boomerang and then imported into Instagram. Now you can create Boomerang videos directly within Instagram from your Stories but not from within your regular Instagram feed. To use Boomerang just swipe to left to select it.
As to whether or not Instagram will roll out the URL links to the rest of it's Users it is still to be seen though this is probably the number feature that all Users want. Brands who enjoy the additional reach that Stories like Snaps give them are sure to be giving good feedback as to how they are working!
