Many of our apps allow you to pick a winner in multiple ways.
To choose a winner, just go to the Winners page of your left sidebar menu when managing your offer.
Depending on your offer you'll have multiple choices.
"Pick A Winner" - This lets you pick winners at random, choose one at a time, or multiple at once. You can also choose between specific dates of entry as well.
"Referrals" - Only available in Sweepstakes, Pin-To-Wins, and Quizzes, this will show you the top 50 users with the most referrals. If you want to award users based on referring others into the contest, you'd want to look here to see who referred the most people.
Top Votes: In a Photo, Video, or UGC contest, you'll see a third option. If you're doing a voting based contest you can see who the top votes are easily by clicking "Top Votes".
For flexibility reasons, our app does not contact any winners when they're chosen. You can send them a personalized email or contact them through other means (Facebook promotional guidelines do require you to contact them outside of Facebook, however).
