Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it. **Card class:** [Hero](/nerve-centre/overview#card-classes-explained) • **Category:** [Cross-Channel: Revenue at Risk](/nerve-centre/connectors#connectors-by-type) ## At a glance > **Session Frustration vs Cart Abandonment** is a cross-channel 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. | | | | --------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **What it counts** | FullStory session frustration plotted on a dual axis against the store's cart abandonment rate across the period. | | **Sample type** | Backend API data from FullStory combined with the connected ecommerce platform, refreshed on the standard data refresh. | | **Why it matters** | It links a soft experience signal to a hard revenue outcome. Co-moving spikes turn "we should improve UX" into "this specific friction is costing this many abandoned carts". | | **Reading the value** | Look for the two lines moving together. A frustration spike that precedes or coincides with an abandonment spike is the actionable pattern. | | **Currency** | percent | | **Time window** | `30D` | | **Alert trigger** | `frustration spike co-occurs with abandonment spike` | | **Sentiment key** | `fs_xc_session_quality_vs_cart_abandonment` | | **Roles** | owner, marketing | ## 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. ## Sibling cards merchants should reference together | Card | Why merchants reach for it | | ---------------------------------------------------------------------------------------------------------- | ------------------------------------------- | | [`ful_cart_abandonment_rate`](/nerve-centre/kpi-cards/fullstory/cart-abandonment-rate) | The abandonment side of this comparison. | | [`fs_frustration_score`](/nerve-centre/kpi-cards/fullstory/avg-frustration-score) | The frustration side of this comparison. | | [`fs_checkout_path_frustration`](/nerve-centre/kpi-cards/fullstory/checkout-path-frustration-events) | Checkout-specific friction behind the link. | | [`fs_form_abandonment_rate`](/nerve-centre/kpi-cards/fullstory/form-abandonment-rate) | Form friction that feeds cart abandonment. | | [`fs_high_frustration_sessions`](/nerve-centre/kpi-cards/fullstory/high-frustration-sessions-review-queue) | The replays that prove the cause. | ## 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:** | Reason | Direction | What to do | | ---------------------------------------------------------------------------------------------------------- | --------- | ---------------------------------------- | | **Abandonment definition.** How the platform defines an abandoned cart affects the line. | Variable | Align the abandonment definition. | | **Period boundary.** Vortex IQ uses 30-day rolling by default; source dashboards may use calendar periods. | Variable | Match the period range. | | **Timing alignment.** Frustration and the resulting abandonment may not fall on the exact same hour. | Variable | Allow for a short lag between the lines. | **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 sensitivity is configurable per profile in the Sensitivity tab. Tune how closely the spikes must align to trigger. *** ### Tracked live in Vortex IQ Nerve Centre *Session Frustration vs Cart Abandonment* is one of hundreds of KPI pulses Vortex IQ tracks across FullStory and 70+ other ecommerce connectors.
