How Coolblue should run Meta ads.

Thin electronics margins make first-order prospecting a losing game. The machine runs on the catalogue, retargeting, and the service premium that earns the repeat.

Our read

The margin decides the plan. At roughly 16% gross on a ~€220 basket, the contribution per order is thin, so chasing new customers to a first-order ROAS is a losing game, the break-even sits near 6×. Coolblue doesn't win there. It wins on the catalogue feeding retargeting, on accessory and service attach that thickens the order, and on a repeat rate built by being the easiest, fastest, most human retailer to buy from.

So the paid-social job isn't prospecting efficiency, it's keeping the retargeting pool full and the feed clean, then measuring on blended contribution including attach and repeat, not last-click ROAS on a single product ad. Spend follows blended payback, and the "glimlach" service story is the creative moat that justifies paying full price instead of chasing the cheapest box.

The economics we assumed

AOV

€220

Est. gross margin

~16%

Break-even ROAS

~6×

Blended target

~2.5×

Real: revenue €2.56B (2025), 75% electronics, order margin 3–7%. Estimated: AOV ~€220, ~16% gross margin (electronics benchmark), so first-order break-even ROAS lands near 6×. You never run prospecting to that; you target a blended ~2.5× that leans on accessory attach and repeat. Our estimates from public figures, not Coolblue's data.

Set it up

Main campaign

Advantage+ Shopping off the product catalogue, weighted to retargeting. At these margins, cold prospecting is a small line item; warm and catalogue traffic is where it pays.

Catalog / feed

The engine. Clean feed with live stock and price, plus product sets for the high-margin categories (accessories, services, energy). Push those sets harder than the thin-margin hardware.

Objective

Sales, optimised for Purchase, server-side via the Conversions API. Track accessory and service attach as a second value.

Targeting

Broad for the catalogue campaign; retargeting off browsers and cart-abandoners. Layer purchase-based lookalikes only once volume is high.

Placements

Advantage+ (all placements).

Budget

Weighted to retargeting and high-margin product sets. Scale on blended contribution, not per-ad ROAS.

Creative

Feed for the products; a small set of service-premium videos on top (delivery, install, real people). See below.

The first three weeks

Fix the feed, weight the sets. Clean the catalogue, then split product sets so the accessory and service ranges get their own budget. Launch retargeting first.

Measure blended, with attach. Judge on account-level contribution including accessories and repeat, not a single product ad's ROAS. Add the service-premium videos for cold reach.

Scale where it pays. Add budget to product sets that clear blended ~2.5×. Keep cold prospecting small; it exists to refill retargeting, not to hit ROAS.

Creative angles

Feed first. The catalogue carries the mid and lower funnel with dynamic product ads. The two concepts below sell the one thing a price-comparison shopper can't get from a marketplace: the Coolblue service premium.

How we built this plan

We modelled the economics from Coolblue's published revenue and category mix plus electronics-retail margin benchmarks. The derived numbers are estimates, not Coolblue's data, meant to show what a thin-margin, catalogue-and-service plan looks like and what "good" is.
