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.
