At a glance

Form Abandonment Rate % is a frustration-signal metric tracked from FullStory data. It measures the share of visitors who started interacting with a form, a checkout step, a newsletter signup, an account creation, and then left without submitting it. Because FullStory captures the field-level interaction, this is not a guess: it knows the visitor focused a field and never completed. A high rate flags forms that are too long, confusing, or throwing validation errors that the visitor cannot get past.

Calculation

Calculated automatically from your FullStory data. FullStory detects form interaction and submission events; Vortex IQ divides started-but-not-submitted form sessions by total started-form sessions for the period. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A representative reading of Form Abandonment Rate % for a typical merchant on FullStory. Suppose the checkout form shows a 47% abandonment rate, over the 40% guardrail. Replays of abandoned sessions cluster on the phone-number field, which rejects spaces without a clear message. Visitors retype, fail again, and leave. Relaxing the validation drops abandonment back toward the high thirties. Without this card the merchant would only see a soft checkout conversion rate with no field-level cause. For deeper investigation, use Vortex Mind to trace the abandonment to specific fields; for natural-language exploration, ask Ask Viq which forms abandon most.

Reconciling against the vendor’s own dashboard

Where to look in FullStory’s own dashboard: FullStory surfaces form interaction through its funnel and conversion tooling, where you can define a form-start and form-submit step. Confirm the form definition and period match the Vortex IQ profile to reconcile cleanly. Why the Vortex IQ value may legitimately differ: Cross-connector reconciliation: complement with the checkout-frustration and cart-abandonment cards for the full picture. For divergence investigations, use Vortex Mind.

Known limitations / merchant FAQs

Q: How often does Form Abandonment Rate % update? The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard. Q: Does a visitor who returns later and submits still count as abandoned? If the submission happens in a separate session outside the window, the original session may still register as abandoned. Treat the rate as directional and confirm patterns in the replays. Q: Why does my FullStory dashboard show a different number? The most common reasons are period-boundary differences, how the form-start step is defined, and segment scope. Match these settings before assuming a real divergence. Q: Can I customise the alert threshold? Yes, alert thresholds are configurable per profile in the Alert Rules tab. The 40% default is a starting point; tune it to your own baseline.
