How is Snapchat a key to reaching your audience?

You can take a photo or short video and have some fun with it. In order to build brand awareness, focus on creating a series of Snaps that tell a story. Motivate people to keep coming back in order to get the whole story. This will surely help you grow your audience! Here have a look at this example: 

In 2014 a candy brand Sour Patch Kids had a goal to grow awareness among teenagers in the United States. They decided to use Snapchat to focus on delivering “fun, highly-shareable content”. Sour Patch Kids used it's slogan “sour-then-sweet” to inspire their snaps, putting a creative edge on cultural conversations.

The company also partnered with social influencer Logan Paul, they started a campaign on the streets of New York City for five days, playing pranks and sharing their product. What was the result of this campaign? Well, during that week they managed to earn 120,000 NEW snapchat followers and also grew their Snap impressions from 500,000 to over 2 million.
