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.

Product & margin-based segmentation. ProductCaster CSS partnership.
Smart reinvestment
CSS savings funnelled into the highest-converting product groups.
WORKSTREAMS

What we actually did.

01

Margin-based segmentation
Restructured Google Shopping into distinct campaigns by product category & profit margin. Bids and budgets aligned to profitability goals, not vanity volume.

02

ProductCaster CSS partnership
Joint partnership with Jigsaw Media and ProductCaster unlocked a 20% CPC saving across every click. Reinvested directly into the best-performing categories.

03

PMax overhaul
Killed the single catchall PMax. Replaced with margin-aware asset groups, custom labels and exclusion strategies giving real control over where budget went.

04

Reporting that meant something
Improved product-level visibility means Trade Mart can now predict future performance, react to seasonal trends and make proactive campaign decisions.
