How to Boost Your Event Registration Form
Registration forms lose people quietly. Someone starts, hits a field they cannot answer, and closes the tab. This looks at what to cut, what to keep and how to make a form easy enough to finish on a phone in one sitting.
Most registration forms are longer than they need to be, because every team with a stake in the event asks for one more field. The result is a form built for internal reporting rather than for the person filling it in, and people give up part way through. The first question worth asking of every field is whether anyone will actually act on the answer.
After that it is mostly about clarity: plain labels, a sensible order, required and optional marked honestly, and dietary or access questions phrased so people know what you are asking. Assume plenty of registrations happen on a phone, so open the form on one before you send the link. If someone can get through it without stopping to think, you will see it in your completion rate.
