Allocating your budget between Google Search and Display Networks is a strategic decision that hinges on your campaign’s primary objectives, the stage of your customer’s journey, and the nature of your product or service. There is no universal “best” split, but there is a best process for determining it, rooted in clear goals and iterative testing.
Understanding the Core Difference
First, it’s crucial to internalize the fundamental roles each network plays:
- Google Search Network: This is for capturing demand. Your ads appear when people are actively searching for keywords related to your business. It’s intent-driven, often lower-funnel, and typically has a higher immediate conversion rate but can come with a higher cost-per-click (CPC).
- Google Display Network (GDN): This is for generating awareness and building demand. Your ads appear on millions of websites, apps, and YouTube videos across the internet. It’s about reaching people based on who they are (demographics, interests) and what content they’re viewing. It’s upper-funnel, excels at brand building and remarketing, and generally has a lower CPC but a lower immediate conversion rate.
A Strategic Framework for Budget Allocation
Following a disciplined, data-driven approach-much like the “lean startup” and goal-oriented methodology we employ at Sagum-is key. Here’s how to think about it:
1. Establish Your Primary Goal & Funnel Stage
Your goal dictates the starting point. Align your budget with your most pressing business objective, just as we collaborate with clients to establish goals that are meaningful to their success.
- Goal: Immediate Sales/Leads (Lower-Funnel): Lean heavily into Search initially (e.g., 70-80%). Use Display for remarketing to users who visited your site but didn’t convert.
- Goal: Brand Awareness & Reach (Upper-Funnel): Lean into Display initially (e.g., 60-70%). Use highly visual and engaging formats to tell your story to a broad, targeted audience.
- Goal: Full-Funnel Growth: This requires a more balanced, yet dynamic, approach. A common starting test ratio is 60% Search / 40% Display. The Display budget fuels top-of-funnel awareness, which should, over time, increase branded search volume and improve the efficiency of your Search campaigns.
2. Begin with a Hypothesis and Test (The 30, 60, 90 Day Plan)
Don’t guess. Model your approach after our “30, 60, 90” day planning. Start with a clear hypothesis based on your goal.
- Days 1-30 (Launch & Learn): Implement your chosen starting split (e.g., 70/30 Search/Display). Instrument everything correctly-ensure conversion tracking and your analytics dashboard (like our custom BI dashboards with Grow) are flawlessly set up to “see the data,” which is as critical as water to us.
- Days 31-60 (Analyze & Adjust): Review performance data. Is Display driving valuable site traffic that later converts? Is Search capturing demand efficiently? Use this data to adjust the budget split. Perhaps you shift 10% from Search to Display prospecting because you see strong engagement metrics.
- Days 61-90 (Optimize & Scale): Double down on what’s working. If you discover a specific Display audience segment that converts nearly as well as Search but at half the cost, reallocate budget there. Your split is now informed by real-world performance, not just theory.
3. Key Tactical Considerations for Each Network
For Search Budgets: Focus spend on high-intent, commercial keywords. Use smart bidding strategies (like Target ROAS or Maximize Conversions) to let Google’s AI optimize for your goals. Segment budgets between brand vs. non-brand terms.
For Display Budgets: Do not let it run wild. Segment this budget purposefully:
- Prospecting (New Audiences): Use custom intent, affinity, and demographic targeting.
- Remarketing (Past Visitors): Create separate campaigns for cart abandoners, product viewers, and general site visitors. This is often where Display delivers its highest ROI.
- Placement & Topic Targeting: Use managed placements for high-quality sites relevant to your audience.
The Final Verdict: It’s a Dynamic Balance
The “best” split is not a fixed number but a dynamic balance that evolves with your data. It requires the focus and accountability of a dedicated manager (like our assigned Digital Marketing Managers) who can constantly interpret the dashboard, communicate findings, and pivot strategy.
Start with a goal-driven hypothesis, commit to a structured testing period, and let performance data guide your reallocation. The power lies not in finding a perfect initial ratio, but in building a data-first system that allows you to confidently shift budget to wherever it drives the most meaningful business outcomes.
