The #1 CSS partner for peak performance
Since 2018, we’ve helped Europe’s leading retailers generate billions in incremental sales by appearing exactly where it counts: in the Shopping carousel, at the precise moment a customer decides to buy.
In 2024 alone, we delivered over £1.2BN in additional sales for our partners.

From small gains to serious results.
Don't just perform. Outperform.
You're looking to capture every possible sale. We help you win more through CSS. We create new Shopping carousel listings for you, optimised to appear to more shoppers ready to buy. Getting your products better visibility when it counts. Helping you capture more sales for your bottom line. Win-win.
Complementary, never competitive.
Google never shows identical products twice in one carousel. We enter the auctions you're skipping. When we overlap, your internal listings take priority. The result: additional placements that expand your visibility, rather than cannibalise it.
Making your budget work harder
Your performance machine already works hard. We build on those efforts. We simply create additional Shopping carousel listings that complement what you're already doing with Shopping campaigns. Getting more eyes on your carousel ads, more clickthroughs to your site, and a greater ROAS. Because every sale matters.
Eyes on the prize.
More eyeballs on your ads.
We don’t chase vanity metrics. We focus on what matters: provable, repeatable, incremental growth.

With Redbrain, you’re in control of your spend.
You control commissions
You decide what you're willing to pay, within our sector benchmarks. We optimise to that target. Simple, transparent, and always in your hands.
No hidden fees
No setup costs, monthly retainers, or long-term contracts. Just an extra boost to your existing sales, from the moment you switch us on.
Laser-focused on your success
You only pay commission when you make a sale from our Shopping carousel ads. Our incentives are completely aligned with yours. Together, we win.
No More Black Boxes. Just Clear Results.
We built Redbrain on a simple idea: our clients deserve total transparency and a partner whose goals are perfectly aligned with their own. In performance marketing, trust is everything. Yet many partners operate behind a wall of vague reports and secret algorithms. You are expected to trust the process without ever seeing the full picture. We do things differently. We give you the keys.
Our real-time Performance Dashboard is your single source of truth, offering complete visibility into the campaigns we run for you. Anytime you want it, you can see exactly what we see.
