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 > **Listings Failing Feedonomics Validation** is the share of items that fail your feed-management validation rules before they can publish or update to Depop. When a brand syndicates a BigCommerce catalogue out to Depop through a feed platform like Feedonomics, every item must pass validation, complete fields, valid categories, acceptable images. The ones that fail never reach Depop, so they are silent lost listings. This card surfaces the failure rate so the gap does not go unnoticed. | | | | --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **What it counts** | The percentage of items failing feed validation rules in the syndication path to Depop over the window. | | **Sample type** | Cross-channel feed-validation data evaluated against the Depop publishing path, refreshed on the standard data refresh. | | **Why it matters** | A failed item never lists, so it can never sell. Unlike a removal, there is no notification; the listing simply never appears. A rising failure rate quietly shrinks your live Depop catalogue and the revenue it would have produced. | | **Reading the value** | Lower is better. A small percentage is normal noise; a rate above roughly 5 percent means a systematic mapping or data-quality issue is blocking real inventory. | | **Currency** | percent | | **Time window** | `7D` | | **Alert trigger** | `> 5%` | | **Sentiment key** | `dep_xc_feed_rejection_vs_listings` | | **Roles** | owner, operations, engineering | ## Calculation The card divides items failing feed validation by total items attempted in the syndication path to Depop over the window, expressed as a percentage. Vortex IQ reads validation outcomes from the feed layer and the Depop publishing path; the alert percentage is configurable in the Sensitivity tab. ## Worked example *A representative reading of **Listings Failing Feedonomics Validation** for a typical brand syndicating to Depop.* Over 7 days the failure rate jumped to 8 percent, above the 5 percent line. Vortex Mind grouped the failures and found most shared one cause: a category field that had changed format upstream and no longer matched the required mapping. Because it was one rule, not hundreds of bad items, the engineering owner fixed the mapping and the failures cleared on the next feed run. The recovered items published to Depop within a cycle. To investigate, ask Ask Viq for the top feed-validation failure reasons this week. ## Sibling cards merchants should reference together | Card | Why merchants reach for it | | ------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------- | | [`dep_xc_catalogue_drift_vs_bc`](/nerve-centre/kpi-cards/depop/listings-drifting-from-bc) | Cross-channel sibling: drift and feed errors often share a root cause. | | [`dep_xc_listed_but_oos`](/nerve-centre/kpi-cards/depop/active-depop-listings-for-sold-elsewhere-items) | Cross-channel sibling: another way the catalogue falls out of sync. | | [`dep_alert_listing_rejection_spike`](/nerve-centre/kpi-cards/depop/depop-removed-listings-24h) | Compliance sibling: failures that publish then get removed. | | [`dep_total_listings`](/nerve-centre/kpi-cards/depop/active-listings) | Catalogue sibling: failed items never reach this count. | | [`dep_revenue_at_risk`](/nerve-centre/kpi-cards/depop/revenue-at-risk) | Outcome sibling: unpublished inventory is forgone revenue. | ## Reconciling against Depop **Where to look in Depop's own dashboard:** These items never reach Depop, so they are invisible in the Depop app by definition. Reconcile against your feed platform's validation report, which lists failed items and reasons; the Vortex IQ rate aggregates those failures against attempted items. **Why the Vortex IQ value may legitimately differ:** | Reason | Direction | What to do | | ------------------------------------------------------------------------------------------- | --------- | --------------------------------------- | | **Denominator scope.** The rate is failures over items attempted, not your whole catalogue. | Variable | Confirm what counts as attempted. | | **Feed run timing.** Failures clear on the next run after a fix. | Variable | Allow a feed cycle before re-reading. | | **Rule configuration.** Validation rules live in the feed platform. | Variable | Confirm rules match Depop requirements. | **Cross-connector reconciliation:** this card lives at the seam between your feed platform and Depop. Read it with catalogue drift and the removals alert for the full publishing-health picture.

Fix the underlying data or rule and the item validates and publishes on the next feed run. The risk is leaving failures unnoticed, which this card prevents. **Q: Why group failures by reason?** Because most failures share a few root causes, a changed field format, a broken category mapping, a missing image rule. Fixing the rule clears many items at once, which is far faster than editing each. **Q: Can I customise the alert threshold?** Yes, the failure-rate threshold is configurable per profile in the Sensitivity tab. *** ### Tracked live in Vortex IQ Nerve Centre *Listings Failing Feedonomics Validation* is one of hundreds of KPI pulses Vortex IQ tracks across Depop and 70+ other ecommerce connectors.
