When collecting conference metrics, there are various methods and tools to choose from, depending on the type and source of data. For example, registration and ticketing systems can provide information on the number, type, and demographics of attendees, as well as the revenue generated by ticket sales. Surveys and feedback forms can measure the satisfaction, learning, and feedback of attendees, speakers, sponsors, and exhibitors. Additionally, social media and web analytics can show the reach, engagement, and sentiment of your online audience. Mobile apps and QR codes can track the behavior, preferences, and interactions of attendees during the conference. Finally, RFID and NFC tags can monitor the movement, location, and dwell time of attendees in different areas of the venue.
