We are entering a golden age for event data where more data is available and tools are smarter, allowing for improved targeting, offerings, and resource allocation. Event data can provide insights into loyalty spend, retention, consumption, time spent at events, favorite sessions, transactions, and behaviors which differ year to year for first-time attendees, new companies or exhibitors. Suppliers should make their data available to clients, while organizers should provide aggregate data and exhibitors should ask for the data. The future includes more data collection through technologies and customized experiences through machine learning.
