How long should your Facebook posts be to get the most engagement? What words drive the most retweets on Twitter? What time should you send email to get the most opens? Our keynote speaker has the answers! Using massive data sets, social media scientist Dan Zarrella studies social media behavior from a data-backed position to teach marketers scientifically grounded best practices. His presentations, webinars and data have made him the web’s preeminent social media scientist, and someone whose expertise is backed by more data than nearly anyone else in the marketing field. We love his recently published book, The Science of Marketing, When to Tweet, What to Post, How to Blog, and other proven strategies. Copies will be available for purchase at the conference.
