Have you ever felt uneasy managing large catalogs in Google Performance Max, almost like you’re handing over your wallet to an algorithm? I sure have.
La Maison Simons faced a similar struggle. With too many products and not enough control, they decided to rebuild their segmentation using Channable Insights. This change turned their perplexing campaign into a revenue powerhouse.
Step 1: Stop segmenting by category
Initially, Simons divided campaigns by product category. It seemed like a good idea until their popular sweater consumed the entire budget, leaving less visible or new products unnoticed.
Static segmentation brought limited visibility and sluggish decision-making. Marketers were trapped with manual tweaks, while Google auto-focused on what’s already succeeding.
Step 2: Segment by performance
With Channable Insights, product-level data like ROAS and clicks now fuel dynamic grouping:

Products automatically transition between segments based on performance. As Etienne Jacques, Digital Campaign Manager at Simons, expressed:
“One super popular item no longer takes all the money.”
Step 3: Shorten your analysis window
Instead of the usual 30-day signals, Simons decided to use a rolling 14-day window. This means quicker reactions, more accurate decisions, and less wasted spend in a fast-paced catalog.
Step 4: Push the strategy across channels
Why limit the strategy to Google? Simons applied the same segmentation across:

- Meta
- TikTok
- Criteo
This cross-channel consistency amplifies optimization.
Step 5: Watch the metrics climb
Simons unlocked impressive results without increasing ad spend:
- ROAS growth: from ~800% to ~1500%
- CPC decrease: $0.37 to $0.30
- CTR lift: 1.45% to 1.86%
- 14% increase in average order value
- 1300% ROAS for New Arrivals campaigns
- Faster workflows and fewer manual tweaks
Even previously invisible products turned into unexpected profit drivers with a spot in the limelight.
Step 6: Treat automation as control, not chaos
Automation has restored marketing control rather than taking it away. Now, teams can learn from data and actively influence product growth instead of leaving everything to PMax autopilot.
Your action plan
- Classify products as Stars, Zombies, and New Arrivals.
- Automate campaign reassignment based on real-time data.
- Refresh product insights every 14 days.
- Roll out segmentation logic to every paid channel.
- Scale what wins – test what’s yet to succeed.
