# Amazon Marketplace

Presence tells you a company sells on Amazon. Timing shows how the storefront is moving — so outreach can prioritize accounts with a live reason to talk.

_Data source — Amazon Marketplace signals Propensify detects: review velocity, sales rank, catalogue movement, quality checks, and growth-phase patterns._

Channel identity and attribution live here. Channel voice — returns, defects, stockouts — lives on Customer reviews and Company socials.

- **Also read:** [Customer reviews](https://propensify.io/data-sources/customer-reviews) — returns, defects, felt-tricked language
- **Also read:** [Company socials](https://propensify.io/data-sources/company-socials) — stockout comments and in-channel voice

## Presence is a gate. Timing is prioritization.

### Presence

A validated Amazon seller, storefront, or ASIN-bearing product page attributable to the company.

### Timing

Movement over a research window (typically ~90 days): reviews, rank, catalogue, and seller feedback — alone or stacked.

## How marketplace evidence stacks

Four timing axes — read each alone, then stack when you want a stronger reason to reach out now. Growth-phase labels sit on the stacked reading, not on a fifth axis.

1. **Reviews** — Demand
2. **Sales rank** — Purchase
3. **Catalogue** — Footprint
4. **Feedback** — Seller activity

- **Four axes:** Reviews, rank, catalogue, and seller feedback each move on their own — one clear signal can prioritize an account.
- **Stack when useful:** Combine axes when you want a stronger now-reason. Do not treat every seller as in-market.
- **Growth phase:** Pattern cards label the stacked reading — expanding, mixed, or contracting — not a fifth exclusive continuum.

## Timing signals

Four ways a storefront can move. Each row is one axis — cards show how strong (or weak) that movement looks.

One clear signal can prioritize an account. Stack a few when you want a stronger reason to reach out now.

## Review velocity

Lagging demand proxy from review accumulation over the window.

_Stronger → weaker_

- **Accelerating:** Demand momentum compounding — prioritize now.
- **Growing:** Clear upward demand without needing acceleration.
- **Decelerating:** Still growing, but cooling — sequence after true accelerators.
- **Flat:** Avoids false urgency when reviews aren’t moving.
- **Declining:** Cooling demand — don’t treat every seller as in-market.
- **Missing:** Keeps scoring honest when history can’t support a claim.

## Sales rank

Category-relative purchase momentum. Glyphs show business direction, not the raw rank number.

_Improving → declining_

- **Improving:** Relative purchase momentum inside a category.
- **Flat:** Prevents over-reading noise as a timing trigger.
- **Declining:** Losing category position — deprioritize vs real movers.
- **Missing:** Explicit coverage gap instead of a silent miss.

## Catalogue footprint

ASIN count and product footprint change — a separate growth axis from reviews or rank.

_Expanding → contracting_

- **Expanding:** Listing push often implies inventory and ops scale.
- **Flat:** Stable footprint — no invented catalogue urgency.
- **Contracting:** Portfolio reduction — don’t assume expansion.
- **Missing:** Transparent when storefront history isn’t measurable.

## Seller feedback

Seller-profile reputation timing — useful when fresh; de-weighted when stale.

_Active → missing_

- **Momentum:** Secondary confirmation of recent seller activity.
- **Stale:** Don’t treat a quiet profile as current demand.
- **Missing:** Coverage honesty when profile history isn’t there.

## Checks

Simple confirmations that sit alongside timing — presence, live catalogue breadth, and quality at scale — including when those checks don’t fire.

## Checks

- **Presence verified:** Confirms a real marketplace operator — not a brand-name guess.
- **Active ASIN cluster:** Live catalogue breadth beyond a single hero SKU.
- **No active cluster:** Avoids overstating activity when the footprint looks thin.
- **Quality at scale:** Momentum attached to products buyers rate well.
- **Quality at scale not detected:** Surfaces weak quality evidence before you invest outreach time.

## When signals stack

Combinations that are sharper than any single axis — plus a plain-English growth phase when evidence is strong enough.

## Composites

- **Multi-dimensional growth:** Higher-confidence “why now” than any single axis.
- **Rank leads reviews:** Momentum without review confirmation — dig deeper.
- **Reviews lead rank:** Early social-proof heat that may precede rank confirmation.
- **Expansion with contraction:** Portfolio rotation — not a binary growing/dying label.
- **Scale without quality:** Volume growth that may not be the account you want.
- **Stale seller, active products:** Weight product timing; ignore the quiet seller profile.

## Growth phase

When evidence is strong enough, dimensions roll up into one phase for prioritization queues.

## Phases

- **Accelerating:** Review velocity up + sales rank improving + no contraction.
- **Expanding:** Velocity or rank up + catalogue/ASIN growth.
- **Mixed:** At least one dimension improving and one declining.
- **Sustaining:** Measured dimensions flat within thresholds.
- **Decelerating:** Velocity declining/flat + rank worsening/flat + no growth.
- **Contracting:** Catalogue contraction with soft velocity and rank.
- **Unclear:** Insufficient evidence for a meaningful phase.

## What it looks like in a verified fit

Amazon timing evidence lands as findings on the account — with the same Fit and Signals score grammar as the product.

## Findings

- **Accelerating review velocity**
- **Sales rank improvement**
- **Multi-dimensional growth**

## Boundaries & method

- Timing windows follow available history (commonly ~90 days); thresholds can be tuned per ICP.
- Review velocity is a lagging demand proxy — not direct GMV or unit sales.
- Sales rank is category-relative; absolute meaning depends on category depth.
- Catalogue expansion can reflect rotation or onboarding — not always net business growth.
- Coverage states (missing, stale) are first-class — we prefer “insufficient data” over weak speculation.
- Seller-level timing requires verified attribution; unattributed brand-store products may inform product demand only.
