Abandonment Rate
Abandonment rate measures the share of entrants who start a giveaway's entry process but leave before finishing it, often because the form is too long or asks for too much information too soon. Example: if a giveaway form has 5 fields and most entrants drop off right after the phone number field, that step is responsible for most of the abandonment rate, a strong signal to make that field optional or move it later in the flow. The lower the abandonment rate, the closer the completion rate gets to 100%.
