On-site, off-site, and in-store retail media: differences, data, and a unified campaign model
On-site retail media operates across retailer-owned digital channels, such as e-commerce websites and mobile apps. Off-site uses retailer data or audience segments beyond its proprietary channels. In-store retail media encompasses physical store media and experiences, including screens, audio, kiosks, and shelf-edge formats.

Three environments, distinct roles
On-site is closely aligned with product search and online conversion. Off-site drives incremental reach and retargets specific audience segments. In-store delivers impact right where the shopper sees the physical product, evaluates variants, and makes the purchase decision at the shelf or checkout.
A unified campaign requires shared identifiers
An omnichannel plan should share a common campaign ID, product SKU, flight dates, location cluster, creatives, budget, and KPI definitions. This does not mean measurement should be identical. An on-site click is not equivalent to an OTS impression before a screen. Reporting must respect channel-specific nuances before consolidating outcomes.
Data and privacy
First-party data can inform media planning, but not every data linkage is necessary or compliant. In-store environments often gain maximum value from aggregated sales, zone, dayparting, and footfall metrics. Network architecture must minimise personal data while clearly defining processing purposes and operational accountability.
The Nedilo perspective
Nedilo powers the in-store layer and seamlessly exchanges campaign data and delivery reports with the wider retail media ecosystem. The platform’s role is to guarantee verified playback and physical store context—without artificially flattening diverse channels into a single, generic metric.
Frequently asked questions
How does in-store differ from DOOH?
In-store applies to media within a retail network and leverages retailer data, including sales data. Traditional DOOH encompasses outdoor/public spaces outside the network and relies on different measurement and sales models.
Can a multi-channel campaign be reported jointly?
Yes, at the level of a shared campaign identifier and shared objectives. However, channel-specific metrics should be presented separately, rather than reduced to a single blanket figure.
What data connects these channels?
Typically a shared product, flight date, location cluster, and campaign objective, alongside sales data on the performance side.
Does retail media include in-store audio?
Yes. In-store audio is a measurable communication channel and can form part of a retail media offering, provided it has dedicated play logs and frequency rules.
