The Starting Point: A Struggling eCommerce Brand
Before the transformation, this mid-sized Shopify store selling eco-friendly home goods faced common problems:
- Low click-through rate (CTR)
- High cost per acquisition (CPA)
- Poor conversion tracking
- Inconsistent ad copy and audience targeting
Despite offering quality products and investing in ads, their ROI plateaued at 2.5x — far below industry benchmarks.
They knew something had to change.
Step-by-Step: The Google Ads Tweaks That Transformed Their ROI
Here are the key adjustments that led to a 2x increase in ROI , without a significant budget boost.
1. Restructured Campaigns Around Profit Margins
Instead of treating all products the same, they segmented campaigns based on profitability .
What They Did:
- Used custom labels in Google Merchant Center to group products by margin tiers
- Allocated higher bids to high-margin items
- Paused or reworked low-performing SKUs
Why It Worked:
Better alignment between spend and return. Each dollar invested went toward products that delivered stronger returns .
2. Pruned Low-Performing Products
Not all products perform equally well in Shopping Ads. They reviewed product-level data weekly and paused underperformers.
Metrics Tracked:
- ROAS (Return on Ad Spend)
- Click-Through Rate (CTR)
- Conversion Rate (CVR)
- Cost Per Click (CPC)
Result:
Improved overall account health and reduced wasted spend by over 30% .
3. A/B Tested Product Titles and Descriptions
Small tweaks to language can significantly impact relevance score and user engagement.
Before:
“Organic Bamboo Toothbrush – Eco Friendly”
After:
“Eco-Friendly Bamboo Toothbrush – Natural & Sustainable Oral Care”
They also tested emotional triggers: “Perfect for Zero-Waste Lovers”
“One Small Change for Your Routine, One Big for the Planet
These subtle shifts increased CTR and improved Quality Score over time.
4. Shifted Bidding Strategy Based on Audience Intent
Instead of using standard bidding across the board, they aligned bidding strategies with search intent .
By adjusting bids according to customer journey stage , they saw better conversions and lower customer acquisition costs.
5. Leveraged Smart Shopping & Performance Max Campaigns
After running Standard Shopping campaigns for months with moderate success, they migrated to Performance Max — Google’s next-gen ad format.
Results:
- Unified campaign management
- Broader reach across YouTube, Gmail, and Display Network
- Auto-optimized for conversions
They set clear ROAS targets and let machine learning handle placements and bid adjustments.
Within 6 weeks, ROAS improved from 3.2x to 5.8x , with CTR rising by 18% .
