Photo Contests – Photo contests are great for a number for reasons – they’re relatively easy to enter (anyone with Instagram and a few spare seconds can submit), and they also provide sponsors with a great form of user-generated content that can be reused and implemented elsewhere.

Video contests – Not as many people will enter video contests, but you’re more likely to get a higher caliber of content since creating a video requires more effort on the user’s part. This kind of content can be extremely valuable for businesses down the line, especially when you have talented filmers creating video content just for you!
Submit your vote contests – Voting contests get a ton of entries because they’re so easy to participate in (just click a button, in most cases). What’s cool about voting contests is that you can use the data obtained from the votes to create a mini data study. Share what you learned in a blog post!
Caption Contests – Post a photo and ask users to submit their best caption – this kind of contest can get some pretty great laughs.
Sweepstakes – The most traditional of contests, sweepstakes/giveaways are a tried and true classic. They are quick and simple to enter – plus it’s easy to ask for email subscriptions as part of the submission form.
Marketing Ideas for Contest Promotion
Post to deal sites – People love free stuff, some more than others. The people who really love a good deal tend to frequent deal sites and forums. There’s almost always a sweepstake/contest forum section where you can add your contest into the mix.
I’ve seen contests in which 90% of traffic is driven from these types of sites – alright, they aren’t always the most qualified leads, but if you want quantity over quality, this is a sound strategy. Start of submitting to Slickdeals and go from there. This can be a great form of restaurant marketing.
Hashtag-ify your contest – Adding a relevant (and unique) hashtag to your contest helps you keep track of entries and makes them easy to scan through and organize. Besides, they’re just plain fun.
Make contests super sharable – This means adding “share this contest” buttons if you have an entry form on a website, or simply encouraging social sharing in general. The more people who know about your contest, the merrier (for you anyway)! Need more ideas for Facebook?
Offer bonus points for sharing – If you offer users bonus points for sharing news of your contest via social media, they’ll be much more likely to concede. Tools like Rafflecopter make it easy to offer users extra entries for different actions (e.g. Joining the mailing list = +5 entries. Sharing contest on Twitter = +2 entries).
Notify email subscribers of contest – Remember, you already know that your email subscribers like you and are interested in what you have to offer. If you’re running a contest for a free year of your software, you know your subscribers are going to want in!
Promote your contest on (all) social media – If you’re running a photo contest via Instagram, make sure you still promote the contest on Facebook, Twitter, Pinterest, etc. You want all your followers, across all social media networks to know about your great giveaway!
