Long before your event starts, your event page and online community should be in place with FAQ's and people in place to answer questions quickly and honestly.
Here are 7 steps to help you grow your event with Twitter:
*Create a unique event hashtag and start a TWUB. Start using it early and often. Make sure to ask and remind your attendees, speakers and sponsors to use it consistently.
*Set up social listening tools to monitor conversations around your event. This will help you understand in a concise way, what your attendees liked and disliked.
*Engage attendees before, during and after the event.
*Use Twitter to share, curate & post content relevant to your event.
*Create "click to Tweets" for your blog and use them from the conception of your events.
*Use followerwonk to find additional event attendees, speakers and targeted prospects.
*Read every post, comment, email or suggestion and reply.
Remember that your communities ability to interact with the event attendees and planners is key. You'll also want to take a moment each month to introduce an attendee to the community and thank them for participating.
