Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it. **Card class:** [Sensitivity](/nerve-centre/overview#card-classes-explained) • **Category:** [Revenue at Risk](/nerve-centre/connectors#connectors-by-type) ## At a glance > The money tied to listings that have drifted out of sync with your source of truth, usually your DTC catalogue, in a way that risks sales. Catalogue drift means the Amazon listing no longer matches the canonical product: a wrong price, a stale title or image, a changed pack size, a discontinued variant still live, or an attribute that no longer matches the DTC record. This card values the revenue exposed by that drift so an owner, marketing, or finance lead can see the cost of letting the Amazon catalogue fall out of step. It is a cross-channel card because the comparison is Amazon listing versus DTC source of truth. | | | | ------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **What it counts** | The estimated revenue at risk from ASINs whose Amazon listing has drifted from the DTC source of truth in a sales-affecting way (price mismatch, content mismatch, pack/variant mismatch, or discontinued items still live). | | **Cross-channel basis** | Compares the live Amazon listing against the canonical DTC catalogue. The drift is the delta; the revenue at risk is the value of the affected ASINs' sales exposed by it. | | **Why it matters** | Drift quietly erodes conversion and trust: a wrong image or stale title lowers conversion, a price mismatch can break margin or trigger MAP issues, and a discontinued variant still live invites returns and bad reviews. | | **Relationship to other drift cards** | The catalogue-level comparison is [Catalogue Drift vs DTC](/nerve-centre/kpi-cards/amazon-seller/catalogue-drift-vs-dtc); the price-specific risk is [MAP Violation Risk (vs DTC)](/nerve-centre/kpi-cards/amazon-seller/map-violation-risk-vs-dtc). This card is the money roll-up. | | **Chart** | KPI value. | | **Unit** | Currency. | | **Time window** | `30D`. | | **Alert trigger** | `>$1k/month` (drift-exposed revenue above roughly one thousand per month in account currency). | | **Roles** | owner, marketing, finance | ## Calculation Calculated automatically from your Amazon Seller Central data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading. ## Worked example A UK home-fragrance brand selling on amazon.co.uk and its own Shopify DTC store. Period: 01 Apr 26 to 30 Apr 26 (30D). | ASIN | Drift type | DTC source of truth | Amazon listing | 30D revenue exposed | | ----------------------------------------------- | ------------------------ | ---------------------- | ---------------------- | ------------------- | | B0XXXX1 | Pack size mismatch | Now a 3-pack | Still listed as single | £640 | | B0XXXX2 | Price drift | £24 DTC list | Listed at £18 | £980 | | B0XXXX3 | Stale content | New scent name + image | Old name and image | £410 | | B0XXXX4 | Discontinued, still live | Removed from range | Still buyable | £290 | | **Catalogue Drift Revenue at Risk (this card)** | | | | **£2,320** | ```text theme={null} Revenue at risk = £2,320/month exposed to drift Alert threshold = £1k/month → card raised Largest driver = B0XXXX2 price drift (£980) and B0XXXX1 pack mismatch (£640) ``` Three things to notice: 1. **Each drift type carries a different harm.** The price drift (£980) is a margin and MAP problem, the pack mismatch (£640) drives wrong expectations and returns, the stale content (£410) suppresses conversion, and the discontinued-but-live item (£290) generates orders you cannot fulfil to spec. The total is one number, but the fixes are four different jobs. 2. **Price drift is the most urgent.** Selling the £24 DTC product at £18 on Amazon erodes margin and undercuts your own channel, which can breach MAP and train customers to buy the cheaper Amazon offer. Cross-check [MAP Violation Risk (vs DTC)](/nerve-centre/kpi-cards/amazon-seller/map-violation-risk-vs-dtc) and re-align the price first. 3. **The discontinued item is a returns and review trap.** A product removed from your DTC range but still buyable on Amazon means customers receive something you no longer support, which invites returns and negative feedback. Close or update the listing before it costs more than the £290 of revenue it carries. With £2,320/month exposed the card is raised (`>$1k/month`). The action: re-align the price drift, correct the pack-size and content mismatches against the DTC source of truth, and retire the discontinued listing.

These give the detail and the specific risks: | Card | Why pair it with Catalogue Drift Revenue at Risk | | ---------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- | | [Catalogue Drift vs DTC](/nerve-centre/kpi-cards/amazon-seller/catalogue-drift-vs-dtc) | The per-ASIN list of what has drifted, behind this money total. | | [MAP Violation Risk (vs DTC)](/nerve-centre/kpi-cards/amazon-seller/map-violation-risk-vs-dtc) | The price-specific slice of drift, where the Amazon price has fallen below your DTC list price. | | [Channel Mix (Amazon vs DTC)](/nerve-centre/kpi-cards/amazon-seller/channel-mix-amazon-vs-dtc) | Context on how much each channel matters, which scales how serious cross-channel drift is. | | [Revenue at Risk (live)](/nerve-centre/kpi-cards/amazon-seller/revenue-at-risk-live) | The account-wide roll-up of all live revenue-at-risk signals, of which drift is one. | | [Suppressed Listings](/nerve-centre/kpi-cards/amazon-seller/suppressed-listings) | Severe drift (missing required attributes) can tip a listing into suppression, removing it entirely. | ## Reconciling against Amazon Seller Central **Where to look in Seller Central:** This card has no single native equivalent, because it compares Amazon against an external source of truth (your DTC catalogue). To verify it manually you compare two sources: > **Amazon side:** Seller Central → Inventory → Manage Inventory, for each listing's live price, title, images, and attributes. > **DTC side:** your canonical catalogue (Shopify admin, PIM, or master spreadsheet) for the same SKUs. Where the two disagree in a sales-affecting way, that ASIN's revenue is the exposure this card values. Amazon shows only its own side; the drift only exists relative to your source of truth. **Timing and reporting-lag table:** | Topic | Detail | | ----------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- | | **Source-of-truth freshness** | The comparison is only as current as the DTC catalogue feed. A change made on the DTC side moments ago may not yet be reflected in the comparison. | | **Amazon listing freshness** | Listing fields are read each sync; a correction you just pushed to Amazon takes a short while to clear from the drift list. | | **Revenue basis** | Revenue exposed uses the affected ASINs' recent sales as the value at risk; it is an estimate of exposure, not a settled loss. | | **Match quality** | Drift detection depends on reliable SKU/ASIN mapping between Amazon and DTC. Unmapped products cannot be compared and are excluded. | **Why our number may legitimately differ from a manual check:** | Reason | Direction | Why | | ------------------------------- | ----------------- | ------------------------------------------------------------------------------------------------------------------ | | **SKU mapping gaps** | Ours can be lower | Products without a clean Amazon-to-DTC mapping are not compared, so genuine drift on unmapped SKUs is not counted. | | **Source-of-truth lag** | Either direction | If the DTC catalogue feed is stale, the comparison reflects the last known DTC state, not the live one. | | **Revenue-at-risk is modelled** | Estimate | The money figure is an exposure estimate based on recent sales, not an Amazon-reported loss. | **Cross-connector reconciliation:** | Card | Expected relationship | What causes legitimate divergence | | ------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------- | | DTC catalogue / Shopify product data | **This card is the join.** It only exists because Amazon and DTC are both connected; the drift is the difference between them. | If the DTC connector is not linked or SKU mapping is incomplete, the card under-reports because it cannot see the source of truth for some products. | ## Known limitations / merchant FAQs **What counts as "catalogue drift"?** Any sales-affecting difference between your Amazon listing and your canonical DTC catalogue: a price mismatch, a stale title or image, a changed pack size, a different attribute, or a discontinued product still live on Amazon. It is drift relative to your source of truth, not an Amazon error. **Why is the revenue figure an estimate?** Because it values the exposure, the recent sales of the drifted ASINs, rather than a settled loss. Drift does not always cost you the full amount; it puts that revenue at risk through lower conversion, returns, margin erosion, or MAP issues. Treat it as a prioritisation figure. **Does this need my DTC store connected?** Yes. The card is a cross-channel comparison; it needs both the Amazon listing data and the DTC source of truth. Without the DTC side connected and SKUs mapped, there is nothing to compare against and the card cannot populate. **How is this different from the MAP violation card?** [MAP Violation Risk (vs DTC)](/nerve-centre/kpi-cards/amazon-seller/map-violation-risk-vs-dtc) is the price-only slice: where the Amazon price has dropped below your DTC list price. This card is broader, it covers price drift plus content, pack-size, attribute, and discontinued-item drift, rolled up into a single revenue-at-risk figure. **A SKU drifted but it is not showing here. Why?** Most likely it is not cleanly mapped between Amazon and your DTC catalogue, so the comparison skips it. Confirm the SKU/ASIN mapping. Drift can only be detected on products the system can match across both sides. *** ### Tracked live in Vortex IQ Nerve Centre *Catalogue Drift Revenue at Risk* is one of hundreds of KPI pulses Vortex IQ tracks across Amazon Seller Central and 70+ other ecommerce connectors.
