Wettbewerbe » Tag a Friend Sweepstakes

One method is to provide an opportunity for users to submit their contact information (as in the example above), and another is to enter by sharing the contest with a friend.
When it comes to sharing, one quick and easy method to allow people to enter is to get them to tag a friend on Instagram of Facebook.
Basically all you need to do is create a post that describes what the grand prize is, and then ask users to tag a friend in the comments below for a chance to win.
