From attendees to customers and revenue
Maximizing Event Marketing ROI
Event marketing delivers high ROI when executed properly. Target 300-500% ROI for trade shows and conferences. The key is optimizing each funnel stage: attract qualified attendees through pre-event promotion, capture 30-50% as leads with engaging booth/presentations, and close 15-20% with immediate follow-up. A $10,000 event generating 60 leads (200 attendees × 30%) and 9 customers (60 × 15%) at $5,000 each produces $45,000 revenue - 350% ROI. Focus on lead quality over quantity, follow up within 48 hours while warm, and track long-term customer value beyond initial sale.
- Include all costs: booth, travel, staff time, materials
- Target 30-50% lead capture rate for trade shows
- Follow up within 24-48 hours for best close rates
- Track CAC: should be 3-5× lower than customer LTV
- Compare event ROI to other marketing channels
- Measure long-term value: initial sale + upsells + referrals
