Every term that shows up in RankASIN docs — ASIN, SKU, UPC, ACoS, TACoS, and 25 more.
Definitions for every term used across RankASIN docs and the app UI.
Products and identifiers
| Field | Type | Required | Description |
|---|---|---|---|
| ASIN | identifier | yes | Amazon Standard Identification Number. A 10-character alphanumeric code unique to a product variant in the Amazon catalog. |
| Parent ASIN | identifier | no | Umbrella ASIN for a variation family (e.g. a t-shirt offered in three sizes). The parent ASIN does not itself have a buy box or sell directly. |
| Child ASIN | identifier | no | A specific variant within a variation family — the sellable unit with its own inventory, price, and buy box. |
| SKU | identifier | no | Stock Keeping Unit. A seller-defined identifier for a listing, distinct from ASIN. One ASIN can map to multiple SKUs across accounts. |
| UPC | identifier | no | Universal Product Code. A 12-digit barcode used as the product identifier before an ASIN is assigned. RankASIN stores UPCs in the same asin_code field and the dedicated upc column. |
| Brand | identifier | no | The brand name as registered in Amazon Brand Registry. Enables access to A+ Content, Brand Analytics, Sponsored Brands ads, and the Brand Store. |
Accounts and teams
| Field | Type | Required | Description |
|---|---|---|---|
| Organization | account | no | Top-level account in RankASIN. An organization contains one or more seller accounts and can have multiple members with different roles. |
| Seller Account | account | no | A single Amazon selling account (Professional seller account) linked to an organization. All reports, ASINs, and campaign blueprints are scoped to a seller account. |
| Marketplace | account | no | The Amazon storefront country (e.g. US, UK, DE). RankASIN tracks the marketplace on each seller account. |
| Owner | role | no | Full admin access to an organization — can manage members, billing, and all data. |
| Editor | role | no | Can create, edit, and delete content but cannot manage organization settings or billing. |
| Viewer | role | no | Read-only access to all organization data. |
Advertising metrics
| Field | Type | Required | Description |
|---|---|---|---|
| ACoS | metric | no | Advertising Cost of Sales — ad spend divided by attributed ad revenue, expressed as a percentage. Lower is more efficient. Target varies by margin; a common starting threshold is 25–30%. |
| TACoS | metric | no | Total Advertising Cost of Sales — ad spend divided by total revenue (organic + paid). TACoS trending down over time indicates growing organic share, which is the goal. |
| CPC | metric | no | Cost Per Click — the amount paid each time a shopper clicks an ad. Amazon Ads uses a second-price auction, so you pay the next bidder's amount plus one cent. |
| CTR | metric | no | Click-Through Rate — clicks divided by impressions. Low CTR suggests weak creative (image or title) for the placement. |
| CVR | metric | no | Conversion Rate — orders divided by clicks (also called Unit Session Percentage in Business Reports). A healthy CVR for Amazon is typically 10–15%+ for established products. |
| ROAS | metric | no | Return on Ad Spend — ad revenue divided by ad spend. Inverse of ACoS; higher is better. |
| Buy Box | metric | no | The "Add to Cart" button placement on a listing. Winning the Buy Box is required for ads to run. Buy Box percentage is the share of page views where you held it. |
| Placement modifier | setting | no | A bid multiplier applied on top of the base keyword bid for a specific placement — Top of Search, Rest of Search, or Product Pages. Values range from 0% (no modifier) to 900%. |
| Match type | setting | no | Controls how loosely Amazon matches a keyword to customer search terms. Options: Exact, Phrase, Broad, Broad Modified. Auto campaigns use automatic targeting rather than keywords. |
| Ad product | setting | no | The ad format. SP = Sponsored Products (keyword and ASIN targeting). SB = Sponsored Brands (headline banner). SBV = Sponsored Brands Video. SDI = Sponsored Display image. SDV = Sponsored Display video. |
| Negative keyword | setting | no | A term explicitly excluded from triggering an ad. Negative Exact blocks that exact query; Negative Phrase blocks any query containing the phrase. Applied at campaign or ad-group level. |
Ranking and reports
| Field | Type | Required | Description |
|---|---|---|---|
| BSR | metric | no | Best Sellers Rank. Amazon's real-time sales rank within a category. Lower rank (closer to 1) means more sales. BSR is a lagging indicator — it reflects recent velocity, not keyword position. |
| A10 | concept | no | The informal name for Amazon's current product-ranking algorithm. Compared to A9, A10 gives more weight to organic sales velocity, external traffic, seller authority, and click-through relevance. |
| COSMO | concept | no | Amazon's semantic understanding layer that maps search intent to product attributes, not just keyword matching. Important for understanding why a product ranks for terms not in its listing. |
| Rufus | concept | no | Amazon's AI shopping assistant, introduced in 2024. Answers shopper questions directly in search results. Listings with structured, factual content (bullets, A+, Q&A) are more likely to be surfaced by Rufus. |
| Keyword Master | feature | no | RankASIN's unified keyword list — the set of ranked and classified keywords attached to an ASIN. Built by harvesting from SQP, TST, and STR reports, then tiered and classified. |
| SQP | report | no | Search Query Performance. A brand-analytics report showing impressions, clicks, cart adds, and purchases for every search query that surfaced your ASIN. Available weekly and monthly. Requires Brand Registry. |
| SCP | report | no | Search Catalog Performance. A brand-analytics report similar to SQP but at the catalog (brand) level rather than per-ASIN. Upload alongside SQP for cross-reference analysis. |
| TST | report | no | Top Search Terms. Shows the top 1,000 search terms in a category seeded by a keyword, plus the top 3 clicked ASINs and their click/conversion share for each term. Used for competitor research and keyword discovery. |
| STR | report | no | Search Term Report. An Amazon Ads report showing which customer search terms triggered your ads, along with impressions, clicks, spend, and orders. The primary source for keyword harvesting and negative targeting. |
RankASIN-specific
| Field | Type | Required | Description |
|---|---|---|---|
| Tier | concept | no | Keyword priority tier (1, 2, or 3) in the Keyword Master. Tier 1 = highest strategic priority; tier 3 = supporting/long-tail terms. Distinct from ASIN tier assignment. |
| Keyword class | concept | no | Per-ASIN classification assigned by the listing classification engine or manually. Values: conviction (manually pinned focus keyword), proven (ranking + converting), opportunity (showing signal but not yet ranking), none (unclassified). See Conviction / proven / opportunity. |
| Hero | concept | no | ASIN tier assignment for top performers (overall score 4.5 or above). Gets the most ad spend and optimization attention. |
| Growth | concept | no | ASIN tier assignment for products with strong potential (score 3.5–4.4). Prioritized for listing optimization and moderate ad investment. |
| Long-tail | concept | no | ASIN tier assignment for steady but low-volume products (score 2.5–3.4). Maintained with minimal active work. |
| Evaluate | concept | no | ASIN tier assignment for underperforming products (score below 2.5). Flagged for review — consider optimizing, discounting, or sunsetting. |
| Diagnostic | feature | no | RankASIN's per-ASIN audit that scores title, bullets, images, A+, keywords, and ads. Runs automatically after keyword harvest. Produces an action plan. |
| Action plan | feature | no | A prioritized list of improvement tasks generated from the diagnostic. Each item has an effort and estimated impact rating. |
| Mission board | feature | no | The dashboard's progress tracker for the current optimization phase. Tracks completion across all active work streams. |

| Strategy brief | feature | no | A seller-authored document attached to an ASIN that captures positioning, target customer questions, and audience notes. Feeds the AI listing optimizer as context. See Strategy briefs and keyword classes. |
