At a glance

Session Frustration vs Cart Abandonment is a cross-platform card that overlays FullStory’s session frustration against your store’s cart abandonment rate over time. The hypothesis it tests is the most actionable one in ecommerce UX: that visitors abandon carts because they hit friction, not just because of price or shipping. When a frustration spike and an abandonment spike line up on the same dates, you have evidence that fixing the experience will recover sales, and a replay queue to prove exactly what broke.

​
Calculation

Calculated automatically from your FullStory and ecommerce-platform data. Vortex IQ plots session frustration against cart abandonment on a shared timeline and flags windows where both rise together. 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 Session Frustration vs Cart Abandonment for a typical merchant on FullStory. Suppose abandonment jumps from 68% to 79% over three days and the frustration line spikes on the same days. Opening the high-frustration replays from that window shows the shipping-options widget failing to load, leaving the total blank, so wary shoppers leave. The overlay made the link obvious; without it, the abandonment rise would have been blamed on price. Fixing the widget pulls abandonment back. For deeper investigation, use Vortex Mind to confirm the causal step; for natural-language exploration, ask Ask Viq whether frustration is driving abandonment.

Reconciling against the vendor’s own dashboard

Where to look in FullStory’s own dashboard: The frustration line comes from FullStory; the abandonment line comes from your ecommerce platform. Reconcile each against its own source over identical dates, then compare the timing of the spikes. Why the Vortex IQ value may legitimately differ: Cross-connector reconciliation: this card is itself a join, so use Vortex Mind to confirm the causal direction when the lines move together.

​
Known limitations / merchant FAQs

Q: How often does Session Frustration vs Cart Abandonment 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 co-movement prove causation? Not on its own, but it is strong evidence and it points you straight to the replays that confirm it. Watch the high-frustration sessions from the spike window to see the actual cause. Q: Why does my FullStory dashboard show a different number? The most common reasons are the abandonment definition, period boundaries, and timing alignment between the two lines. Align these before assuming a real divergence. Q: Can I customise the alert threshold? Yes, the co-occurrence alert threshold is configurable per profile in the Alert Rules tab. Tune how closely the spikes must align to trigger.
