Google Shopping Ads are the fastest way to drive qualified traffic to your Shopify store.
When someone searches “blue running shoes,” Shopping Ads show product images, prices, and your store name—right at the top of search results. These visual ads capture attention and drive high-intent clicks.
Average ROAS across our clients: 420% (That’s $4.20 revenue for every $1 spent)
Here’s how to replicate that success.
Why Shopping Ads Work
Unlike text ads, Shopping Ads show:
- Product image
- Price
- Store name/rating
- Availability
Customers see what they’re getting before clicking, which means: ✅ Higher click-through rates ✅ More qualified traffic ✅ Lower cost per conversion
Setup: The Technical Foundation
Step 1: Google Merchant Center
Before running Shopping Ads, set up Merchant Center:
- Create account at
merchants.google.com - Add your Shopify store URL
- Connect Google Shopping app in Shopify
Step 2: Product Feed Optimization
Your product feed is crucial. Google pulls data from your Shopify catalog:
Required fields:
- Product ID (SKU)
- Title
- Description
- Link
- Image link
- Price
- Availability
Optimization tips:
Title Format:
Brand - Product Type - Key Features - Color/Size
Example: “Nike - Running Shoes - Lightweight Breathable - Black/White - Men’s Size 10”
Why this works: Google matches search queries to your title. More relevant keywords = more impressions.
Description (500-1000 characters): Include:
- Primary benefits
- Use cases
- Materials
- Key specifications
- Size/fit info
Use natural language (not keyword stuffing).
Image Requirements:
- Minimum 800x800px
- White or transparent background
- Show full product
- No watermarks or text overlays
- High quality (no blurry images)
Step 3: Campaign Structure
Create separate campaigns for:
- Best sellers (highest budget)
- New products (test budget)
- Seasonal items (adjusted budget)
- Branded searches (defensive campaign)
Don’t lump everything into one campaign—you lose control over optimization.
Bidding Strategies
Starting Out: Manual CPC
Begin with manual Cost-Per-Click bidding to:
- Understand what clicks cost
- See which products perform
- Gather conversion data
Start conservative: $0.50-1.00 CPC depending on niche.
Scaling: Smart Bidding
Once you have 30+ conversions, switch to:
Target ROAS (Return on Ad Spend): “Google, get me 400% ROAS”
Google’s algorithm automatically adjusts bids to hit your target.
Maximize Conversion Value: “Google, spend my budget to get maximum revenue”
Best for stores with variable product prices.
Negative Keywords
Shopping Ads trigger on search queries Google deems relevant. Add negative keywords to filter out:
- Irrelevant searches: “free,” “diy,” “homemade”
- Information queries: “how to,” “tutorial,” “review”
- Competitor names: Unless you want to compete for their brand
- Wrong products: If you sell “men’s shoes,” add “women’s” as negative
Check search terms weekly and add negatives religiously.
Product Groups & Segmentation
Break campaigns into product groups for granular control:
By Performance
- High performers (high ROAS)
- Medium performers
- Low performers (low budget or pause)
By Margin
- High margin products (aggressive bidding)
- Low margin products (conservative bidding)
By Brand
Different brands have different search volumes and competition levels.
Optimization Tactics
1. Bid Adjustments
Device: If mobile converts worse, reduce mobile bids by 20-30%.
Location: If certain cities/states convert better, increase bids there.
Time of day: If conversions happen mostly evenings/weekends, adjust accordingly.
2. Priority Campaigns
Use campaign priority (High, Medium, Low) to control which campaign serves:
Example:
- High priority: Best sellers, highest margin
- Medium priority: New products
- Low priority: Catch-all for everything else
3. Dynamic Remarketing
Show ads to people who viewed specific products:
“Remember these blue running shoes? They’re on sale now.”
Result: 2-5x higher conversion rate than cold traffic.
4. Promotions
Add sales, discounts, and promotions directly to Shopping Ads:
“20% off” or “Free Shipping”
These show alongside your ad and boost click-through rate 15-30%.
Tracking & Measurement
Conversion Tracking
Install Google Ads conversion tracking to measure:
- Purchases
- Add to carts
- Begin checkout
Without this data, you’re blind.
Key Metrics
Track weekly:
- ROAS (revenue ÷ ad spend)
- CPA (cost per acquisition)
- Conversion rate
- Average order value
- Click-through rate
Good benchmarks:
- ROAS: 300-500%
- Conversion rate: 2-5%
- CTR: 0.5-1.5%
Google Analytics Integration
Link Google Ads to Analytics to see:
- Time on site
- Pages per session
- Bounce rate
- Shopping behavior
This reveals which products attract engaged visitors.
Common Mistakes
❌ No negative keywords (wasting money on irrelevant clicks) ❌ Poor product titles (not matching search queries) ❌ Low-quality images (reducing click-through rate) ❌ One catch-all campaign (no optimization control) ❌ Setting and forgetting (must optimize weekly) ❌ No conversion tracking (can’t measure what matters)
Scaling Profitably
Once you’ve proven campaigns work:
- Increase budget gradually (10-20% per week)
- Expand product coverage (add more SKUs)
- Test new countries (if you ship internationally)
- Layer in Performance Max (Google’s AI-driven campaigns)
The key: maintain ROAS as you scale. If ROAS drops, you’re scaling too fast.
The Testing Mindset
Always be testing:
- Different product images
- Title formats
- Bid strategies
- Campaign structures
- Landing pages
Small improvements compound:
- 10% better CTR
- 10% better conversion rate
- 10% higher AOV
= 33% more revenue from same ad spend
Advanced: Feed Optimization
Use third-party tools to enhance your feed:
- DataFeedWatch: Custom rules, optimization
- Feedonomics: Enterprise-level feed management
Optimize:
- Custom labels (for segmentation)
- Product types (for categorization)
- GTINs (Global Trade Item Numbers—improves visibility)
Budget Recommendations
New stores: Start with $500-1000/month
- Test different products
- Gather conversion data
- Build pixel data
Established stores: 10-20% of revenue on ads
- If making $50k/month, spend $5-10k on ads
Scaling stores: Increase until ROAS drops below target
