How In-Store Media Connects to the Broader Retail Media Stack

The Retail Media Stack

Modern retail media networks operate across three channels. Onsite retail media includes sponsored product listings, display ads, and branded content on the retailer's website and app. This is the most mature and highest-revenue channel. Offsite retail media uses the retailer's first-party data to target ads across the open web, social platforms, and CTV through DSP partnerships. In-store retail media reaches shoppers in physical stores through digital screens, audio advertising, interactive kiosks, and ambient media.

Where In-Store Media Fits

In-store media is unique within the retail media stack because it reaches shoppers at or near the point of purchase, which is where the majority of purchase decisions are finalized. It leverages physical-world assets (screens, speakers, spaces) that the retailer already owns. It can be measured against in-store transactions rather than relying on cross-channel attribution models. It serves both operational purposes (wayfinding, menu boards, promotions) and media purposes (advertising).

Integration Points

Unified Audience Strategy

The most advanced retail media networks use a consistent audience taxonomy across onsite, offsite, and in-store channels. This means the same customer segments used for website personalization can inform in-store signage content and audio advertising targeting.

Cross-Channel Measurement

Connecting in-store media exposure to the same measurement framework used for onsite and offsite media allows brands to compare performance across channels. This requires integrating in-store media platforms with the RMN's measurement and reporting infrastructure.

Content and Campaign Management

Ideally, a brand running a campaign across onsite, offsite, and in-store channels can manage it from a single platform or set of integrated platforms. In practice, in-store media often requires a separate content workflow due to the physical and technical differences from digital channels.

DSP / SSP Connectivity

For programmatic buying, in-store screens and audio inventory need to be available through the same SSPs and DSPs that brands use for other media. Vistar Media, Place Exchange, and Broadsign Reach are the primary SSPs connecting in-store inventory to programmatic demand.

The Convergence Opportunity

For retailers, the strategic opportunity is to position in-store media as a premium extension of their retail media network — not a separate, siloed channel. In-store media commands attention in a way that digital ads cannot (you can ignore a banner ad; you can't ignore a 65-inch screen at eye level). For brands, in-store media closes the gap between awareness (offsite), consideration (onsite), and purchase (in-store). A unified retail media strategy that includes in-store is more valuable than any single channel alone.

Getting Started

Retailers building out in-store media capabilities should audit existing physical assets (screens, speakers, kiosks) across locations, evaluate in-store media platforms that can integrate with existing RMN infrastructure, start with proof-of-play and basic measurement before promising closed-loop attribution, and work with SSPs to make inventory available programmatically alongside existing DOOH and onsite inventory.
