The ability to measure event ROI accurately, and to draw up a detailed analysis that correlates costs and benefits, is a real competitive advantage.
Quantitative, qualitative: a double trigger ROI
An optimized corporate events strategy is a sure bet for your company's growth. The benefits are both qualitative and quantitative.
Direct, easily quantifiable benefits include, in no particular order, increased sales and contracts signed during or after the event, new business opportunities, qualified leads, etc.
More subtle, the qualitative benefits can be seen over time, sometimes a very long time. They are an even better indication of a company's good health. To evaluate this aspect of the ROI of your event strategy, you can draw on several observations:
- You notice an increase in your loyalty capital with your customers and partners.
- The cohesion and motivation of your teams is strengthened post-event.
- Your brand image and reputation will make an impression on your target audiences (social networks, digital and print media).
These more gaseous measurements require longitudinal impact monitoring over several months. This is often the case for your ultra-premium VIP events, those that bring together your best customers and the key players in your business. These are long tail eventsand their real impact is measured over distance.
Our neighbors across the Channel have understood this perfectly: in the first three quarters of 2024, investment in events showed a net balance of 33%. And by the end of 2025, over 15% of companies were planning to increase the share of events in their marketing budgets, despite the uncertain economic situation. (5) (6)
