At a glance
Listings Drifting from BC counts the AliExpress retail SKUs whose live listing no longer matches its BigCommerce source record. In this merchant’s setup BigCommerce is the source of truth, and AliExpress retail listings are expected to mirror BC on price, title, images, and stock. When a listing drifts, a buyer sees a price, photo, or description that the source catalogue has already moved past. That mismatch drives buyer confusion, mispriced orders, and disputes when the delivered product or charged price does not match the listing. The card renders as a table so you can see exactly which SKUs drifted and on which fields.
| What it counts | AliExpress retail SKUs that have diverged from their BigCommerce source record on price, title, images, or stock. Each drifting SKU is one row in the table. |
| Sample type | Backend API data from AliExpress compared against the BigCommerce source, refreshed on the standard data refresh over a rolling 30-day window. |
| Why it matters | Drift breaks the promise that AliExpress mirrors the source catalogue. It causes mispricing, buyer confusion, and disputes when the listing and the source no longer agree. |
| Reading the value | A non-zero count is a worklist. Open the table, sort by the drifted field, and prioritise price and stock drift over cosmetic title drift. |

Calculation
Vortex IQ matches each live AliExpress retail listing to its BigCommerce source SKU and flags any where price, title, images, or stock no longer agree across the two channels. 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 Listings Drifting from BC for a typical BC-to-AliExpress syndicating merchant. On 19 Mar 26 the card reads 23 drifting SKUs, above the 10-SKU alert threshold. The table shows 14 with price drift (a BC price update did not propagate), 6 with stock drift (BC marked them low while AliExpress still shows full stock), and 3 with title drift after a BC copy refresh. The merchant clears the 14 price-drift rows first because those risk underselling, then chases why the feed step failed to push the updates. For deeper investigation, use Vortex Mind to trace upstream causes; for natural-language exploration, ask Ask Viq.Sibling cards merchants should reference together
| Card | Why merchants reach for it |
|---|---|
aex_xc_feed_rejection_vs_listings | Drift often starts when an update is rejected at the Feedonomics validation step. |
aex_xc_listed_but_oos_on_bc | A stock-drift extreme: listings still buyable on AliExpress but out of stock on BC. |
aex_xc_price_parity | Another cross-channel pricing coherence check, this time against Alibaba B2B. |
aex_listings_with_fx_pricing_drift | Price drift caused by currency conversion rather than a stale source value. |
aex_total_listings | The denominator that puts the drift count in proportion to catalogue size. |
Reconciling against AliExpress Seller Center
Where to look in AliExpress Seller Center: Open a drifting SKU in Product Management and read its live price, title, images, and stock. The other half of the comparison does not live in Seller Center: the source values sit in BigCommerce, and the transform that should have synced them runs through the Feedonomics feed layer, so check all three to confirm a true drift. Why the Vortex IQ value may legitimately differ:| Reason | Direction | What to do |
|---|---|---|
| In-flight sync. A BC update may be mid-propagation, so the listing looks drifted for one cycle. | Marginal | Recheck after the next refresh before acting. |
| Intentional channel override. Some merchants deliberately set AliExpress-only pricing or imagery. | Variable | Whitelist intended overrides so they stop counting as drift. |
| FX conversion. A price that looks drifted may simply reflect currency conversion, not a stale source. | Variable | Cross-check the FX pricing drift card before treating it as true drift. |
