FROM CHALLENGES TO SUCCESS
30,000 SKUs, One Broken Campaign
This auto parts brand had a strong product catalog and loyal customer base, but their paid media was running on autopilot. All 30,000+ SKUs were crammed into a single campaign with no differentiation between audiences, creative angles, or funnel stages. The result: rising acquisition costs, stagnant revenue, and no visibility into what was actually working.
Challenges
Inventory Trapped in a Single Campaign
The brand was running their entire product catalog through a single shopping campaign with no segmentation. This created a cascade of problems that compounded over time, making it nearly impossible to scale efficiently.
- No campaign structure: Thousands of SKUs competing for the same budget with no priority tiers, product grouping, or performance-based segmentation.
- Blind spending: No separation between prospecting and retargeting meant the brand couldn’t tell which dollars were acquiring new customers vs. recapturing existing ones.
- Rising nCAC: Without guardrails, customer acquisition costs climbed steadily while revenue plateaued, squeezing margins and limiting reinvestment capacity.
- Creative stagnation: The same ad creative had been running for months with no testing framework, leading to audience fatigue and declining click-through rates.
Solution
A Brand-Tiered Segmentation Matrix
We moved away from the “catch-all” approach and deployed a strict, value-based hierarchy to organize the 30,000 SKU catalog. The goal: prioritize products based on business value (Profitability > Volume) rather than treating every SKU equally.
Profit-First Prioritization
As a reseller, not all brands yield the same margin. We ignored the “long tail” initially and focused resources on the Most Profitable Brands, ensuring these high-margin lines had 100% coverage across both Search and Shopping, effectively dominating the shelf space for the products that contributed most to the bottom line.
Series-Level Granularity
Simply organizing by “Brand” wasn’t enough. We drilled down into Product Series and Price Points to align keywords with user intent. A customer searching for a premium performance kit was no longer shown an entry-level shock absorber. This drastically increased ad relevance and CTR.
Waterfall Expansion
Once the high-profit brands were stabilized, we expanded to High-Volume Brands using a “waterfall” approach, slowly working our way down to lower-visibility products without destabilizing what was already working.
Custom Label Logic
We utilized Custom Labels in the product feed to tag items dynamically as “Top Seller,” “High Profit,” or “High Volume.” This allowed aggressive bidding on winners while suppressing bids on low-margin inventory without manually adjusting thousands of product groups.
Results
Dominating Market Share with Lean Efficiency
In the low-margin world of auto parts reselling, volume means nothing without profitability. By cutting wasted spend on “zombie products” and funneling budget toward high-margin brands, we achieved a rare “double win”: skyrocketing revenue while driving down acquisition costs.
- Revenue scaled from $280K to $1.5M per month (+435%)
- nCAC decreased 30% within the first 3 months
- Maintained 10x MER ensuring the bottom line grew as fast as the top line
- Search Impression Share increased from 40% to 54%
- Total order volume doubled within the first 6 months
$280K → $1.5M monthly revenue in under 6 months
