A2 is a Retail Media Platform (RMP) designed to empower e-commerce and retail businesses to effectively operate and manage their advertising initiatives. With A2, retailers can swiftly introduce diverse advertising products, enhancing advertiser satisfaction while maximizing their media revenue.

A2 Overview

The above image shows an example of ad management using A2. This site has three main ad locations:

  1. Top video banner
  2. Right-side banner
  3. Ads within product listings

A2 refers to the places where ads are displayed as placement.Placement managers can set target revenue (eCPM), permissible ad creatives, and serving rules for each placement.

Ads delivered to a placement are managed by campaign. Campaigns can be configured with various optimization goals, such as impressions, clicks, or conversions, to address a wide range of advertiser needs.

To boost both ad performance and placement revenue, A2 provides various technologies and features, including:

  • Machine Learning: A2 utilizes state-of-the-art machine learning to serve the most relevant ads to each visitor on a given placement.
  • First-Party Data Utilization: By integrating site data—such as customer clicks, purchases, and conversions—and product catalog items with A2, more precise ad targeting and more effective creative generation become possible.
  • Data-Driven Insights: A2 offers analytics to measure the performance of each campaign and placement. For example, you can compare click-through rates for side-banner placements or conversion rates for campaigns within product listings to determine which ad formats yield the best results. This enables advertisers to allocate their budget more effectively to the most profitable placements and creatives.

Through this, advertisers can more accurately reach their target audiences while achieving higher advertising efficiency on a lower budget. Retail site operators can increase advertising revenue on placements without compromising user experience, thereby enhancing satisfaction for both advertisers and customers—and ultimately fostering a virtuous cycle of sustainable business growth.

How to Use A2

A2 offers three account types:

  1. Administrator: Manages permissions, budgets, and system settings for retailers and advertisers
  2. Retailer: Oversees placements, analyzes placement performance, and approves allocations
  3. Advertiser: Manages campaigns, analyzes campaign performance, and requests allocations

You can issue and manage these accounts based on your specific needs. For instance, an administrator might handle site-wide advertising strategy, a retailer might manage ads on specific placements, and an external advertiser might promote their own products—each having role-appropriate permissions and features. If you prefer to operate A2 without distinguishing between retailer and advertiser accounts, you can simply use an administrator account.

When You Want to Quickly Launch an Advertising Business

By leveraging A2’s placement and placement catalog you can rapidly create an ad product catalog to offer to advertisers. Simply provide advertisers with an A2 account so they can register their own ads and request to serve them—your only task is to approve. If advertisers already use a separate system, you can integrate it seamlessly via the Data Management API.

If you integrate first-part data, advertisers can easily use products from their existing catalog registered on your retail site as ad creatives—even if they haven’t registered separate creatives.
