Todd provides tips for using social media to promote events in 3 stages: before, during, and after the event. Before the event, promote on social media by adding handles, hashtags, and asking connections to share. During the event, engage with attendees using the hashtag and share photos. After the event, continue conversations online, write a blog recap, and stay connected to promote future events. The overall advice is to use social media consistently at all stages to create buzz and engage attendees.
