SpaceAid — Brand Due Diligence Report

Executive Summary

Scope, Sources & Methodology

How to read the metrics

Category position

Where the brand's best-ranked listing sits in the Amazon browse category its own listings are filed under, together with the number of listings ranked above it. Taken from Amazon's own published sales rank — not a search term we chose, and checkable in a browser. Rank order says who is ahead, never by how much: it is not a share of category sales.

Catalog covered

The share of this brand's listings that a seller account OFFERS. Measured from Amazon's own offer data, independently of who wins any buy box — an account carrying nearly the whole catalog is behaving like its owner, one carrying a sliver among thousands is a reseller. Evidence of ownership, not proof: legal ownership is not visible from outside Amazon.

Buy box held

The share of the last year a seller account won the buy box, averaged over the listings it actually contests. Measured separately from catalog coverage so the two can be compared: carrying the catalog and winning its boxes is control; carrying it without winning is a brand losing its own shelf; winning boxes it barely carries is a reseller or a hijacker.

Head share

How the measured head of a category — the listings ranked above this brand, plus the brand itself — divides between brands, weighted by rank so higher placements count for more. A share of that head only, never of the whole category.

HHI

Herfindahl–Hirschman Index of niche concentration (Σ of head shares squared, scaled 0–10,000). Below 1,500 = competitive; 1,500–2,500 = moderately concentrated; above 2,500 = concentrated. Read a small field against its floor, not against 0: N participants split perfectly evenly still score 10,000 ÷ N, so across 2 the minimum is 5,000 and across 3 it is 3,333.

Suppressed buy box

No featured offer for the ASIN — typically a pricing, account-health or hijacking signal. Does not by itself confirm a hijacker.

Data quality

Complete = full enrichment; Partial = thin coverage, read directionally.

The Competitive Position

A brand appears once, at the position of its best-ranked listing, so these are Amazon’s own category positions and not consecutive places in a league table — a gap between two rows is another brand’s listing, or another listing of a brand already shown. Head share is each brand’s rank-weighted share of the listings measured at the top of this category, not of the category’s sales.

Demand is this brand's Amazon-measured units sold in the niche, month over month — not the category's demand, which this report does not measure. Amazon publishes units in brackets ("100+ bought"), so on a Partial series a large percentage can be a single bracket step rather than a measured change; read those directionally at most. A dash means the direction was not measured — usually too few months to compare a start window against an end one. Where the brand added or lost listings in a niche, the figure shown is per listing, because the total would count a bigger catalogue as more demand: a niche going from 1 listing to 12 can show a large total rise while each listing sells less than it used to. The listing change and the total are shown beneath it.

The seller census examined 276 of the 846 listings this run analysed (281 ASINs in the catalogue). Shares below are of those examined, not of the whole catalogue.

1 distinct account (other than Amazon’s own retail, reported separately) sell this brand across the 276 listings read. Concentration of the selling is 10,000 against an arithmetic floor of 10,000 for 1 account — read it against that floor, never against zero. What this measures is the spread: a seller’s reported revenue comes from one Seller Central account, while every account counted here sells the brand. Amazon lists this brand among the ten largest brands of 1 account in all, 1 of which has been seen offering in the last 31 days. This read found that account among the 1 account on its listings. Those are also the accounts still offering, so what this read reached and what is currently selling are the same set here. The index counts only brands among a seller's ten largest, so it is a FLOOR, never a total.

Amazon’s own retail arm also stocks this brand on 5 listings examined — a vendor relationship (Amazon buys wholesale and resells it as first party), not a marketplace reseller, and excluded from the count above. It is a channel an acquirer inherits; its terms are worth confirming.

Catalog covered is measured from Amazon’s offer data, independently of who wins any buy box. This report does not establish which account legally owns the brand — that is a trademark and Brand Registry question, outside its scope — and no figure here should be read as doing so. Registered business names are shown where Amazon publishes them.

One rival ahead in one category is a category fact. The same rival ahead across several says the brand is losing to a single competitor portfolio-wide rather than to a different incumbent in each corner — a different problem, and priced differently. Rivals that lead in only one of this brand's categories are deliberately absent from this table and may still dominate the category they are in; they appear in Exhibit C, per category.

Historical Momentum

Trailing ~12-month trajectory from Keepa — the velocity and control signals a point-in-time snapshot can't show. Sparklines read left-to-right; each self-scales to its own range, so shape is the signal, not absolute level. Rank is inverted so up = improving position.

Hero products = top 12 by revenue that carry Keepa history. Rank inverted (up = better); offers and price use natural direction. A dash marks a trend that could not be drawn — too little history, or, in the reviews column, a count that switches between the listing’s own reviews and the pooled total Amazon shows across its variation family. That switch looks like a collapse and is not one, so it is left undrawn rather than plotted.

Rows are listings where the box was contested or held by an account other than the brand's own; a listing the brand holds alone is control, not a finding, and is omitted. The brand's own account is marked brand. A non-brand account dominating the window points to a persistent hijacker; high churn points to an open contested listing. Ambiguous — verify against the brand's authorized-seller list.
