To set a budget for a Google Ads campaign across multiple products or services, follow a strategic, data-driven approach to ensure effective allocation. Here's how you can do it:
✅ 1. Define Campaign Structure
Break down your products/services into separate campaigns or ad groups, depending on how differently you want to manage budgets, targeting, and performance.
-
Separate campaigns if products have very different goals or audiences.
-
Ad groups within a campaign for related products/services.
✅ 2. Set a Total Monthly Budget
Decide how much you can spend overall (e.g., $3,000/month), then break it down into daily budgets for each campaign:
✅ 3. Allocate Based on Business Priorities
Prioritize based on:
-
Profit margins
-
Conversion value
-
Product inventory or seasonality
-
Sales goals or demand
E.g.:
| Product/Service | Priority | Allocation (%) | Budget ($) |
|---|---|---|---|
| High-margin product | High | 50% | $1,500/month |
| New service launch | Medium | 30% | $900/month |
| Low-performing SKU | Low | 20% | $600/month |
✅ 4. Use Shared Budgets (Optional)
Google Ads allows you to set shared budgets across multiple campaigns:
-
Good for flexibility—Google will allocate where performance is better.
-
Avoid if you need strict control per campaign.
✅ 5. Monitor & Optimize
-
Use performance data (CTR, CPC, ROAS, conversions) to reallocate.
-
Pause low-performing ad groups or increase budget to high-performers.
-
Test with automated bidding strategies (like Maximize Conversions or Target CPA) after collecting enough data.
✅ 6. Use Portfolio Bidding (Advanced)
If managing multiple campaigns with similar goals, use portfolio bid strategies to optimize spending and performance across campaigns automatically.
