Definition

Form drop-off is the percentage of users who start filling the registration form but don't complete it. It is one of the critical points of the event funnel: every 1% of form drop-off means hundreds of euros lost in acquisition cost.

Details and formula

Typical rate by number of fields:

  • 3–4 fields: drop-off 15–25% (low)
  • 5–6 fields: drop-off 25–40% (medium)
  • 7+ fields: drop-off 45–65% (high)
  • Multi-step: drop-off distributes across steps. Typically: step 1 conversion 80%, step 2 70%, step 3 60%.

Context and typical ranges

Most frequent drop-off causes:

  • Useless mandatory fields (e.g., fax, tax ID for free events)
  • Unclear fields (e.g., "company" without specifying if it's legal name or brand)
  • Aggressive validation (rejects emails with uncommon domains)
  • Visible captchas (-20% conversion)
  • Form not mobile-optimized (-30% conversion from smartphones)
  • Load time >3s

Quick wins: reduce to 4 mandatory fields, eliminate captchas (use honeypot), gentle validation (warn, don't block).

How it applies in OAK EVENTS

OAK EVENTS measures drop-off field by field in the registration form with abandonment heatmap, automatically identifies the "killer" field (e.g., the 6th field where 18% of users drop), and suggests concrete optimizations based on benchmarks from similar events.
