Retail Media in the UK: Who's Winning the Sponsored Shelf?

Retail media has become one of the fastest-growing advertising channels in the world, and the UK is no exception. What started as a simple pay-to-play sponsored listing on Amazon has evolved into a multi-billion-pound industry where nearly every major retailer now offers brands the ability to buy premium product placement on their digital shelves. For brand managers and e-commerce professionals, understanding this landscape is no longer optional. The retailers you sell through are now also the advertising platforms you buy media from, and the line between organic visibility and paid placement is getting thinner every year.

This article examines the UK retail media landscape as it stands today: which retailers offer sponsored placements, how those placements actually work at a technical level, which brands appear to be investing most heavily, and what the data tells us about the balance between organic and paid visibility. We will also discuss the emerging risks of over-reliance on paid placement and how Share of Voice data can help brands spend smarter.

The UK retail media landscape: who offers sponsored slots

Not all UK retailers participate in retail media. In the consumer electronics and computing space that we monitor at Crawlbot, the retail media landscape breaks down into three tiers.

Tier 1: Sophisticated retail media platforms

Amazon is the undisputed leader. Amazon Advertising is a full-stack ad platform offering Sponsored Products (keyword-targeted placements in search results and category pages), Sponsored Brands (banner placements), Sponsored Display (retargeting), and DSP (programmatic display across the web). For most consumer electronics brands, Amazon advertising is a top-three media line item by spend. On a typical Amazon UK laptop category page, the first 2 to 3 results are Sponsored Products, and additional sponsored placements appear mid-grid and at the bottom of the page. The "Sponsored" label is present but visually subtle, and our data shows that many shoppers do not distinguish between sponsored and organic results.

Currys operates its retail media program through Criteo Retail Media. This is a significant and growing channel. On Currys category pages, sponsored products typically occupy the top 3 to 4 positions in the product grid. The Criteo platform supports real-time bidding, category targeting, and performance reporting. However, as we have written about previously, Criteo's own analytics have limitations: competitor data is anonymised, organic visibility is not measured, and data collection stops when no brands are actively bidding. On Currys laptop category pages, we consistently observe that the first row of results (positions 1 through 4) contains at least 2 sponsored products during business hours, rising to 3 or 4 during peak promotional periods.

Tier 2: Emerging retail media programs

Argos (owned by Sainsbury's) has been building out its retail media capabilities through the Nectar360 platform. Sponsored product placements do appear on Argos category pages, though the implementation is less mature than Amazon or Currys. The frequency and number of sponsored slots varies significantly by category, and the targeting options available to advertisers are more limited than what Criteo or Amazon offer.

Very (part of The Very Group) and AO.com have both experimented with sponsored placements, though their programs are less well-documented publicly. Our monitoring detects sponsored markers on some AO.com category pages, suggesting an active if limited retail media program. Very has been more public about its retail media ambitions, partnering with external ad-tech providers to monetise its digital real estate.

Tier 3: No sponsored placements

Several significant UK electronics retailers do not currently operate retail media programs in the computing category. Scan, Laptops Direct, Overclockers, Box.co.uk, John Lewis, and Costco all show category pages where every product position is organic. On these retailers, your shelf position is determined entirely by the retailer's merchandising algorithm, sales data, stock levels, and content quality. There is no option to buy your way to the top.

This is important strategic information for brands. If you have a strong organic position on Scan or Overclockers, no competitor can outbid you for that slot. Conversely, if your organic ranking is poor on these platforms, there is no quick fix through media spend. You need to improve the fundamentals: content, pricing, reviews, and availability.

How sponsored slots work: the mechanics

Understanding the technical mechanics of how sponsored products are served helps brand managers make better buying decisions. The process differs by retailer, but the general pattern is consistent.

When a shopper loads a category page, the retailer's platform makes a real-time call to its ad server (Criteo for Currys, Amazon's own ad system, etc.). The ad server evaluates all active campaigns targeting that category, runs an auction weighted by bid price, product relevance, and predicted click-through rate, and returns the winning products. These products are then injected into the top positions of the category grid, pushing organic results down by the corresponding number of positions.

This means that if 4 sponsored products are served on a Currys category page, the product that would organically rank in position 1 is actually displayed in position 5. For a brand investing heavily in organic optimisation (content quality, reviews, pricing), this displacement is a real cost. Your "number one" organic product is being pushed below the fold by a competitor's media spend. Without monitoring both sponsored and organic positions simultaneously, you cannot quantify this displacement or respond to it.

The timing dimension

Sponsored placements are not static throughout the day. Campaigns have daily budgets, and when a brand's budget is exhausted, its products are removed from the sponsored slots. This creates a dynamic where the sponsored landscape shifts throughout the day. Our hourly monitoring reveals patterns that would be invisible in a daily or weekly snapshot:

• Morning dominance: Larger brands with higher budgets tend to dominate sponsored positions from 8 AM onwards, capturing the morning commute browsing window.
• Afternoon gaps: By 2 to 3 PM, some brands have exhausted their daily budgets. Sponsored positions either go unfilled (reverting to organic) or are won by smaller brands with lower bids that are now competitive in a thinner auction.
• Evening recovery: Brands using day-parting strategies may reactivate in the evening to capture the 7 to 10 PM shopping peak.
• Weekend variation: Some brands reduce or pause retail media spend on weekends, creating opportunities for competitors to dominate at lower cost.

This hourly variation is one of the most actionable insights that SoV monitoring provides. If your competitor consistently runs out of budget by 3 PM, you can concentrate your spend on the afternoon hours when the auction is less competitive and your cost per click is lower.

Who is investing most heavily

Without naming specific brands (our client data is confidential), we can share general patterns observed across the UK electronics retail media landscape.

In the laptop category, the top 3 advertisers on Currys typically account for 60 to 70 percent of all sponsored impressions. These are major multinational OEMs with dedicated retail media teams and substantial budgets. The remaining sponsored slots are contested by 5 to 8 mid-tier brands, many of which use automated bidding strategies through Criteo's platform. The long tail of smaller brands rarely appears in sponsored positions on high-traffic categories like laptops, because the cost per click exceeds their unit economics.

On Amazon, the competitive intensity is even higher. The laptop category typically shows 4 to 6 sponsored results on the first page, and advertising Cost of Sales (ACoS) for premium positions can exceed 15 to 20 percent. Brands report spending six and seven figures annually on Amazon Sponsored Products in the UK computing category alone.

In niche categories like gaming monitors, projectors, or Chromebooks, the retail media landscape is less congested. Fewer brands bid, auction prices are lower, and it is possible to achieve top sponsored positions with relatively modest budgets. For brands with products in these categories, retail media can offer exceptional return on investment precisely because competitors have not yet saturated the space.

The organic vs paid balance: a growing tension

One of the most significant trends in UK retail media is the gradual expansion of sponsored slots at the expense of organic positions. Three years ago, a typical Currys category page might show 1 or 2 sponsored products. Today, it is common to see 3 or 4. On Amazon, sponsored products can occupy 30 to 40 percent of the visible first page. This trend is driven by retailer economics: retail media is enormously profitable, with margins that far exceed those on the products themselves.

For brands, this creates a strategic tension. If more of the visible shelf is paid, organic excellence matters less and media budgets matter more. Brands that historically won on product quality, reviews, and content are finding that their hard-earned organic positions are being displaced by competitors willing to spend more aggressively on retail media. The digital shelf is becoming a pay-to-play environment.

The risk of over-reliance on paid placement is real. When you stop spending, your products disappear from the top of the page entirely. Unlike organic visibility, which persists based on product merit, sponsored visibility evaporates the moment the budget runs dry.

The smartest brand strategies we see balance both channels. They invest in organic fundamentals — strong content, competitive pricing, review generation, complete specifications — while using retail media strategically to boost visibility during key promotional periods, new product launches, and competitive counter-attacks. They monitor both channels simultaneously so they can see the total picture.

Using SoV data to optimise retail media spend

This is where Share of Voice monitoring becomes a competitive weapon, not just a reporting tool. When you can see both sponsored and organic positions for every brand, across every category, every hour of every day, you can make decisions that would otherwise be impossible.

1. Identify wasted spend

If your product already holds organic position 1 in a category, paying for a sponsored slot in that same category may be cannibalising your own traffic. SoV data reveals when you are bidding against yourself. Reallocating that budget to a category where your organic position is weaker generates incremental visibility rather than redundant impressions.

2. Exploit competitor budget gaps

When SoV data shows that a key competitor's sponsored presence drops off at 3 PM daily, you know their budget is exhausted. You can set your campaign to increase bids in the afternoon, capturing their abandoned positions at lower cost. Without hourly monitoring, this pattern is invisible.

3. Benchmark across retailers

Your retail media budget is probably split across Amazon, Currys, and possibly Argos. SoV data across all three platforms lets you compare the marginal value of a pound spent on each. If your Amazon spend yields position 4 in a sea of 6 sponsored results, but the same spend on Currys gets you position 1 with only 2 competitors bidding, the Currys pound is working harder.

4. Measure the true impact of media

Retail media platforms report impressions, clicks, and attributed sales. But they do not tell you how your total visibility (organic plus sponsored) changed as a result of your spend. SoV data fills this gap. You can compare your total Share of Voice during media-on periods versus media-off periods and calculate the true incremental visibility that your budget purchased.

5. Defend against competitive attacks

When a competitor launches a new product with heavy retail media support, your SoV will drop. Hourly monitoring lets you detect this within the first hour of their campaign launch, rather than discovering it in a weekly report. Early detection means you can respond with counter-spend, promotional pricing, or content updates before the competitor establishes a dominant position.

What the future looks like

The UK retail media landscape is moving in a clear direction: more retailers will offer sponsored placements, more shelf space will be monetised, and brands' retail media budgets will continue to grow. Industry analysts project UK retail media spend to reach three to four billion pounds annually within the next two years. For categories like consumer electronics, where average order values are high and margins are tight, the competition for sponsored positions will only intensify.

This means that the brands which invest in measurement infrastructure today will have a structural advantage. When every retailer is a media platform, the ability to allocate budget efficiently across channels, detect competitive moves in real time, and understand the interplay between organic and paid visibility is not a nice-to-have. It is a core competency.

At Crawlbot, we track the organic and sponsored split across 14 retailers hourly. We detect Criteo-powered sponsored placements on Currys, Amazon Sponsored Products, and emerging retail media markers across other platforms. Our data captures which brands hold which positions, at what times, and whether those positions are earned or bought. This is the intelligence layer that turns retail media from a cost centre into a strategic weapon.

Key takeaways

• Retail media is now table stakes in UK electronics. Amazon and Currys operate mature sponsored product programs. Argos, Very, and AO are building theirs. Scan, Overclockers, and others remain organic-only.
• Sponsored products displace organic results. On Currys, the top 3 to 4 positions in laptop categories are typically sponsored during business hours. Every sponsored slot pushes organic products further down the page.
• The landscape changes hourly. Budget exhaustion, day-parting, and campaign launches create daily variation that weekly reports miss entirely.
• Balance paid and organic. Over-reliance on retail media is expensive and fragile. The strongest brands invest in organic fundamentals and use paid placement strategically.
• Measure both channels together. Retail media platforms only report their own data. True Share of Voice requires monitoring organic and sponsored positions simultaneously across every retailer you sell through.
