THE CHALLENGE
One PMax. Zero control.
Trade Mart were facing significant obstacles in their Google Shopping campaigns. High CPCs, a single broad-targeted PMax campaign, no clear control to steer performance toward high-margin, seasonal or promotional items. Budget was spread too thin across the catalogue with no segmentation, and they were uncertain where to allocate spend for maximum impact.
High CPCs, low efficiency
Budget spread too thin across the catalogue.
Poor ROI on every click.
No strategic targeting
One catchall PMax. No way to steer toward high-margin or seasonal lines.
THE STRATEGY
Margin first. CSS second.
We restructured Google Shopping around product categories and profit margins — separating high-margin lines from commoditised ones so budget tracked profitability, not just revenue. Then we partnered with ProductCaster CSS (alongside Jigsaw Media) to unlock a 20% CPC saving on every click. The savings went straight back into the highest-performing categories, amplifying exposure and driving more conversions.
Two pillars
Product & margin-based segmentation. ProductCaster CSS partnership.
Smart reinvestment
CSS savings funnelled into the highest-converting product groups.
