Companies that do this sort of activities get high levels of interaction. Have your customers like, follow, pin, share your website or posts on the web as a task to find missing items, get clues, or participate in a giveaway.
Follow these instructions to pull this off! Keep in mind than your typical “Like, share and comment” type of contests are losing their touch, instead give small awards to the last people that shared or liked your page, have guessing games, award users that engage the most, have a #hashtag photo contest, make a contest on the most creative way to use your product, possibilities are infinite! Use all your social platforms to promote this! Gleam.io is a great tool for this hack!
