As you consider event promotion ideas, social media has several key benefits. Number one, it's (more than likely) where your audience spends their time, so it's essential for reaching them in the first place. Second, social media event promotion has the potential for exponential exposure – if you share compelling content, and attendees share it with their networks, too, you can reach a much larger audience. Social media also enables a two-way conversation. You can ask questions, crowdsource content and start conversations. So, the question remains: what's the best way to approach social media for your event? Use these five tips and you'll be ahead of the game.
