Key Takeaways

The Highlights

Collaboration built trust and long-term success
Seasonality used capture peak demand
A Feed-first strategy unlocked scalable growth
High-performing products drove smarter optimisation

The Challenge

With the challenge of proving the incremental success a CSS partner can offer in addition to internal activity, the Redbrain team saw an opportunity to boost online sales for B&Q. Initially, campaigns were limited to a subset of key products (Tools & Hardware) to assess impact before expanding to other categories.

The Approach

01/05

A Product Feed built to outperform

Redbrain optimised B&Q’s product feed accuracy to boost visibility and conversion

Performance-led targeting

Campaigns focused on high-performing products and real shopper demand

Seasonality that sells

Insights and Google tools combined to push in-demand products at the right time

Scaling through trust

Proven results led to full-category rollout, built on transparency and collaboration.

Optimisation without pause

Continuous data-led adjustments kept every campaign sharp and performing at its peak.

The Approach

The strategy focused on three key areas -

  • Product feed optimisation
  • Products
  • Seasonality

The Redbrain team quickly identified feed improvements, optimising for product availability and using the [sale_price] attribute. Progressively setting up targeted campaigns around these adjustments, Redbrain quickly gathered performance data on product trends and combined this with Google’s seasonality adjustments tool to push in-demand products. With real-time data monitoring, the team made constant adjustments to drive campaign incrementality. By May 2024, successful campaign performance prompted B&Q to allow Redbrain full access to their product feed. Redbrain optimised these new campaigns based on learnings from initial campaigns, leading to continued strong performance.
