## About RevWise

[RevWise](https://revwise.com/) is an award-winning UK-based specialist affiliate channel management agency that helps e-commerce brands drive scalable growth through strategic affiliate partnerships. Acting as an extension of in-house teams, they focus on unlocking incremental revenue by building, managing and optimising high-value publisher relationships that deliver measurable results.

Their hands-on, data-led approach combines commercial insight with day-to-day execution, ensuring affiliate activity supports wider performance goals and long-term growth. They support a portfolio of retailers through the [Awin](https://www.awin.com/) network.

## Building a Partnership

Recognising that strong affiliate programmes are built on diversity, innovation and data-led partnerships, RevWise made CSS diversification a core pillar of their affiliate strategy. This perfectly aligned with Awin recently reporting that advertisers who embrace a diverse partner mix see an average sales uplift of 33%.

From day one, they included Redbrain within their partner lineup to help retailers unlock additional Shopping performance with a low-risk, CPA model.

Together, they focused on three things:

### Smarter CSS adoption

RevWise identified CSS as a channel capable of driving immediate incremental value. With investment from brands across Awin’s 304 active CSS partners increasing 57% YoY, there was significant opportunity to accelerate growth for their retail clients.

### Feed-first optimisation

A strong foundation was built on clean product feeds and continuous optimisation, ensuring maximum coverage and visibility across high-intent search moments. Redbrain CSS proprietary technology dynamically adjusts bids and applies AI-driven title optimisation, testing variations aligned to the attributes most likely to win Shopping placements.

### Transparent three-way collaboration

RevWise, Awin and Redbrain worked in sync, sharing data, insights, and optimisation opportunities to ensure activity aligned with retailer goals and maintained clear measurement throughout.

## Key strengths

The partnership between RevWise, Awin and Redbrain is a standout example of collaboration and transparency driving real results.

Key strengths included:

- RevWise’s approach with a dedicated CSS Champion, supporting clients through implementation and ongoing product feed optimisation to drive performance.
- Benchmark-driven insights from Awin dedicated to growth.
- Redbrain’s commitment to feedback, incrementality testing and performance data transparency enabling efficient optimisation and powerful scaling.

Across the Top 10 RevWise × Awin × Redbrain retail clients, CSS diversification delivered performance well above Awin benchmarks:

YoY Growth (Sep 2024 -Aug 2025 Vs previous 12 months):

- +136% revenue growth
- +44% uplift in conversions (click → sale)
- +37% increase in click-through rate
- 15:1 average ROI — outperforming Awin’s 14:1 CSS benchmark

Retailers also benefited from:

- Expanded Shopping visibility across competitive retail verticals
- Improved new customer acquisition
- Stronger brand presence in high-intent auctions
- Low-risk, fast-to-activate performance gains

This three-way transparent partnership consistently delivers reliable, incremental revenue for brands, with Redbrain celebrated as being one of RevWise’s top publishers for Q4 growth.

CSS proved to be a low-friction performance lever that could deliver measurable incremental revenue, improve Shopping visibility and support new customer acquisition, without disrupting existing Paid Search strategies or internal reporting.
