ARA key terms

The state in which a seller's product listings, inventory, pricing, and brand registry status meet Amazon's requirements to advertise effectively. Listings must be in stock, buyable, and accurately categorized before campaigns can run.

Whether a product can actually be purchased on Amazon at a given moment. Out-of-stock, suppressed, or unavailable items are not buyable, and ads pointing to them stop serving or waste spend.

The default purchase option shown on a product detail page, awarded to one offer per item. Sponsored Products ads generally link to the winning offer, so losing it can redirect ad traffic to a competitor.

Amazon's program that verifies trademark ownership and unlocks brand-protection tools, A+ Content, Sponsored Brands, Sponsored Display, and Stores. Enrollment is a prerequisite for most brand-level advertising formats.

A status where a product page is hidden from search because it lacks required attributes, has restricted content, or violates policy. Suppressed listings cannot receive ad traffic even if campaigns are active.

Enhanced product descriptions using formatted modules such as comparison charts and images, available to brand-registered sellers. It can improve conversion rate on ad landing pages and is often used alongside Sponsored Brands.

A free, multi-page branded website hosted on Amazon that brand-registered sellers can build. Stores serve as landing destinations for Sponsored Brands and Sponsored Display ads and can be measured for traffic and sales.

Amazon Standard Identification Number, a ten-character identifier unique to each product listing. Advertisers target, exclude, or report on products by ASIN, making it a core unit for campaign structure and analysis.

Stock Keeping Unit, a seller-defined identifier for a specific sellable variant such as size or color. Unlike ASINs, SKUs are unique to a seller and are used for inventory and offer-level tracking.

Cost-per-click ads for individual product listings that appear in search results and on detail pages. They use keyword or product targeting and are the most common format for driving direct sales.

Cost-per-click ads that feature a brand logo, custom headline, and multiple products or a video, linking to a Store or landing page. They require Brand Registry and build brand awareness alongside sales.

A Sponsored Brands ad format that uses an autoplaying video in search results, linking to a product detail page. It is suited to demonstrating product use and capturing attention in competitive results.

Cost-per-click or cost-per-thousand-impressions ads that reach shoppers on and off Amazon using audience and product targeting. They support awareness, remarketing, and defensive or conquesting strategies.

A Sponsored Display audience option that re-engages shoppers who viewed a product detail page but did not purchase within a set lookback window. It is commonly used to recover lost conversions.

Self-service advertising that places video ads on streaming TV content, bought without the managed service of Amazon DSP. It targets broad audiences and is typically used for upper-funnel awareness.

Video advertising served within ad-supported streaming television environments, often purchased through Amazon DSP or managed service. Measurement leans on reach, frequency, and brand-lift studies rather than clicks.

Amazon's demand-side platform for programmatic buying of display, video, and audio ads on and off Amazon. It offers audience targeting, automation, and access to Amazon shopper signals.

Automated, auction-based buying of ad inventory using software rather than manual insertion orders. Amazon DSP enables programmatic access to Amazon-owned and third-party supply with data-driven targeting.

Selecting ad recipients based on attributes such as in-market interest, lifestyle, demographics, or past shopping behavior. It contrasts with contextual targeting, which keys off page content or keywords.

A group of shoppers Amazon infers are actively researching or likely to buy within a product category. Advertisers use these segments in DSP and Sponsored Display to reach near-term buyers.

A DSP audience segment based on inferred long-term interests and habits rather than immediate purchase intent. It suits awareness campaigns aimed at shoppers whose profile matches the brand's customer.

Placing ads based on the content of the page or the products shown rather than on who the viewer is. It works without personal identifiers and is common for product-detail-page placements.

A specific marketplace or publisher where DSP ads can appear, such as Amazon-owned sites, third-party exchanges, or streaming services. Advertisers include or exclude supply sources to control placement quality.

The process of crediting a conversion, such as a purchase, to the ad interaction that earned it. Amazon reports attributed sales using defined windows and models, which affects how campaign performance is judged.

The period after an ad interaction during which a resulting conversion is credited to that ad. Amazon uses windows such as 7 or 14 days for clicks and 1 day for views, varying by report and format.

Revenue from purchases credited to an ad campaign within the attribution window. It is the numerator in return-on-ad-spend calculations and excludes organic sales made without ad exposure.

A metric counting sales or customers who purchased a brand's product for the first time within a lookback period. It helps advertisers distinguish brand growth from repeat purchases.

A conversion credited to an ad impression even though the shopper did not click it. View-through credit is typically measured over a shorter window than click-based conversions.

Return on ad spend, calculated as attributed sales divided by ad spend. A ROAS of 4 means four dollars of sales per dollar spent, and targets vary by margin and campaign goal.

Advertising cost of sales, calculated as ad spend divided by attributed sales, expressed as a percentage. It is the inverse of ROAS and is used to gauge whether a campaign is profitable.

Total advertising cost of sales, calculated as total ad spend divided by total sales including organic. It shows advertising's share of overall revenue and reflects whether ads are lifting the whole business.

The ACOS at which ad-driven sales generate zero profit after product cost and fees. Campaigns above this threshold lose money on each attributed sale, so it sets a practical bid ceiling.

The maximum amount an advertiser is willing to pay for a click or thousand impressions in an auction. The winning bid is combined with relevance and placement to determine whether and where an ad serves.

An automated bidding strategy that adjusts bids in real time based on likelihood of conversion or placement opportunity. Options typically include down-only, up-and-down, and fixed bidding.

A percentage adjustment applied to base bids for specific ad placements, such as top-of-search or product pages. It lets advertisers pay more where performance is stronger without changing base bids.

Serving ads to shoppers whose search queries match chosen keywords, with match types controlling how closely queries must align. It captures demand at the moment of search.

A setting defining how closely a shopper's search must match a keyword, commonly broad, phrase, and exact. Broader match types reach more queries but require negatives to control relevance.

A keyword or phrase that prevents an ad from serving on matching searches. Negatives are used to block irrelevant traffic and reduce wasted spend as campaigns scale.

Serving ads to specific products, categories, or brands rather than to keywords. It is used to place ads on competitor detail pages or to defend a brand's own listings.

A report listing the actual shopper queries that triggered ads along with performance metrics. Advertisers mine it to add converting terms and to add negatives for wasteful ones.

The number of times an ad is displayed, regardless of clicks. Impressions underpin click-through rate and reach calculations and indicate whether ads are serving at all.

Clicks divided by impressions, expressed as a percentage. It measures how well an ad's creative and targeting attract interest and is often a leading indicator of relevance.

The average amount paid each time a shopper clicks an ad, calculated as spend divided by clicks. It reflects auction competitiveness and bid strategy effectiveness.

The average number of times a unique viewer sees an ad within a period. Managing frequency prevents fatigue and wasted budget, especially in streaming TV and display campaigns.

The number of unique people or households exposed to an ad at least once. Reach is a primary upper-funnel metric for streaming TV and DSP awareness campaigns.

The maximum amount a campaign is allowed to spend over a set period, such as daily or lifetime. Caps prevent overspend but can throttle delivery and limit impressions if set too low.

How ad spend is distributed over a campaign's schedule, either evenly or as fast as possible. Proper pacing keeps budgets from exhausting early and maintains consistent delivery.

Purchases that occur without a click or view on a paid ad, such as through free search ranking. Comparing organic and ad sales helps assess whether advertising is incremental.

The portion of sales that would not have occurred without advertising. It is estimated through experiments or control groups and distinguishes true ad impact from sales that would happen anyway.
