Event KPI

Definition

An event KPI (Key Performance Indicator) is a predefined numerical metric that measures the effectiveness of a specific aspect of the event. It differs from a simple metric because it has: 1) a target value, 2) an owner, 3) a consequent action based on the result.

Details and formula

Most relevant B2B event KPIs, grouped:

Pre-event (acquisition):

• Total registrations (absolute target)
• CPR (cost per registration)
• Landing → form conversion
• Channel distribution (% registrations per source)

During (engagement):

• Attendance rate (1 − no-show rate)
• Average session dwell time
• Q&A/poll participation rate
• App download rate over total attendees

Post-event (impact):

• Attendee NPS
• Survey completion rate
• Qualified leads / attendees
• Pipeline value generated
• Event CAC (cost per customer acquired)

Context and typical ranges

The "vanity KPI" trap: measuring metrics that look good (e.g., "we had 1,000 registrations") but aren't actionable. A real KPI must answer "if this value is low, what do we change in the next event?".

Example: "Total registrations 1,000" is vanity. "CPR €35 vs benchmark €20" is actionable (we know we need to optimize channels). The first is just observed, the second generates a decision.

How it applies in OAK EVENTS

OAK EVENTS produces native KPI dashboard pre/during/post event, with comparison against benchmarks of similar events managed on the platform and against previous editions of the same event. Each KPI has configurable alerts when it exits the target, to enable intervention before it's too late.
