After the event, everyone has an opinion about how it went. Numbers settle the argument — and tell you what to change next time. These are the metrics worth tracking.
Before the event
Registrations over time
A chart of bookings per day shows which announcements worked. A spike after an email or a partner post is a channel worth repeating; a flat week is a gap in your promotion calendar.

Sales by ticket type
Which tiers sold, and which did not? A premium tier nobody buys is either over-priced or badly explained. A concession tier that sells out fast may be under-priced.

Revenue — per currency
If you sell in more than one currency, keep them separate. Adding different currencies into one total produces a confident, wrong number.
Where people heard about you
Ask on the registration form and chart the answers. It is the cheapest marketing research you will ever do.
On the day
Check-in rate
Checked-in attendees divided by confirmed bookings. The gap is your no-show rate — often 20–40% for free events and far lower for paid ones.

Attendance per day
For multi-day events, count each day separately. Day-two drop-off is common and tells you about your programme.

After the event
What you actually received
Revenue minus payment processing and platform fees — the number that pays your bills.

Who came
Charts from your own registration questions: institutions, roles, regions. This is what sponsors want to see next year.
Feedback
A short survey sent within two days. Ask one question that matters: would you come again, and why?
Turn metrics into decisions
- Registrations spiked after partner codes → give partners more codes.
- Premium tier did not sell → change what it includes, not just the price.
- High no-show rate → charge a small amount, or remind with something new.
