In-store commerce media

In-store commerce media uses advertising space in a retailer’s physical stores, often planned or measured with retail data. For a UK campaign, ask three questions: will shoppers meet the message at a useful point in their visit, can they buy the advertised product, and what evidence will show the media ran? A screen booking alone cannot answer all three.

Providers and channel portfolios

UK retailers are building media businesses around their owned spaces. Tesco, Boots and Currys hold first-party insights into millions of loyalty members and shoppers. Boots Media Group, with millions of Advantage Card members, works with Threefold Agency on a media solution covering online ads, email, in-app placements and in-store activations.

Choose the job before the format

Decide what the message should help shoppers do: notice a range, find a product or consider an offer. Then choose a location that suits that task.

An entrance can introduce a range; an aisle can give category context; a checkout position offers another, shorter decision moment. These are planning possibilities, not measured claims that one zone performs better.

UK provider Nectar360 lists in-store broadcast and entrance gates among its channels and has described an internal digital-screen rollout.

Nectar360’s published channel portfolio includes in-store formats such as digital 6 sheet, trolley media, in aisle shelf fins, shelf barkers, coupon at Till, and experiential, in-aisle and convenience sampling. These sit across the customer journey alongside mobile app, email, direct mail, display advertising, Sainsbury’s magazine, social media and groceries online. The list mixes store-based formats with online and loyalty channels.

Physical format distribution

Sainsbury’s Live network had over 550 external and internal full-motion digital screens across Sainsbury’s stores. An October announcement extended the rollout to over 800 internal and front-of-store digital screens nationally, in collaboration with Clear Channel. Eleven months later, the programme was halfway through phase three of a four-phase plan, with screens to be rolled out through 2024/25 and front-of-store screens upgraded or installed.

The four-phase plan covered partnership, plan and trial, scale, and future developments or alignment. Phase two considered screen type, energy consumption, data connectivity, colleague impact, customer feedback and governance processes.

Fit the message to the location

Ask for the position, orientation, sightline and likely obstructions. For screens, check the creative length and its share of the loop against the time a shopper might pass the display. For audio, check the stores and areas covered, the schedule and how audibility is assessed. The same creative need not suit both formats.

Sainsbury’s Live screens may carry advertisements and navigational content directing customers to specific products. Nectar360 describes this as further enhancing the customer’s shopping journey.

Connect media coverage to product availability

Compare the proposed media stores with the stores ranging the product over the same dates. Ranging does not guarantee that an item stayed in stock. A broad awareness message may remain useful outside immediately stocked stores; a direction to find a named item needs a closer match.

Keep screen count, store count and shopper traffic separate. Differences in store size, traffic, stock and local demand can also affect sales comparisons between placement groups.

Ask for evidence in layers

A schedule shows what was planned. Playback records and operating-status data provide different parts of the delivery picture. An estimated opportunity to see describes potential exposure under a stated method; it does not prove attention. Ask which traffic, zone, timing and share-of-voice inputs the estimate uses.

IAB Europe opened its in-store measurement proposals for comment in September 2026; they remain proposals rather than a final standard. Ask which definitions the retailer’s report uses.

For sales reporting, agree the eligible products, stores, dates, returns treatment and comparison method. Sales recorded during a campaign are not automatically caused by it. Keep an agreed booking record and compare it with delivery and any changes after the flight.

The September 2026 IAB Europe proposals set out a five-zone framework covering retail media placements from outside the store through to in-aisle environments. They propose a simplified opportunity-to-see model based on six inputs: footfall, store count, campaign duration, number of placements, aisle penetration and share of voice. Impression measurement would focus on footfall and the opportunity for visual contact with an ad, rather than ad play alone.

The same proposals include a tiered approach to aisle penetration, from full beacon deployment to category-level market research, and greater transparency where impressions are modelled without sensor technology. They would remove sales lift and brand sales lift metrics and align the sales reporting window to 28 days. The feedback deadline was 23 October 2026.
