Budget Allocation Planner
Divide an SEM budget across campaigns in proportion to where conversions are most likely
What This Prompt Does
Spreading a paid budget evenly across campaigns feels fair but produces mediocre results. This prompt weighs each campaign's conversion potential and proposes a share-of-budget split, names the assumptions driving the plan, and marks the campaigns that should start small until data proves otherwise.
When to Use It
- •Launching multiple campaigns at once with a fixed monthly budget
- •Reallocating budget after the first 30–60 days of data
- •Seasonal rebalancing (emergency services in winter, HVAC in summer)
- •Preparing a budget proposal for a stakeholder who needs the reasoning
The Prompt Template
Act as an SEM budget strategist. Your goal is to recommend how to divide a paid search budget across campaigns so the business spends more where it is most likely to get results. Context: - Business type: [BUSINESS TYPE] - Monthly ad budget: [BUDGET] - Campaign list: [PASTE CAMPAIGNS OR THEMES] - Conversion goal: [GOAL] - Priority services or products: [PRIORITIES] Task: Recommend: 1. how to divide the budget across campaigns 2. which campaigns deserve the most budget 3. which campaigns should start smaller 4. what assumptions are driving the recommendation Process: 1. Review the campaign themes. 2. Identify the campaigns most likely to produce conversions. 3. Allocate more budget to high-intent, high-value areas. 4. Keep some budget for testing where appropriate. 5. Explain the recommendation in plain English. Constraints: - Use plain English. - Be practical. - Do not spread the budget evenly just to be fair. - Prioritize conversion potential. - State assumptions clearly when data is missing. - Favor recommendations that reduce wasted spend and improve conversion quality, not just click volume. Output format: Return a table with these columns: - Campaign - Budget Share - Why - Notes
How the Prompt Is Structured
"Do Not Spread Evenly"
The most important constraint in the prompt. Equal splits feel equitable but waste money on low-intent campaigns and starve the ones that actually convert.
"State Assumptions Clearly"
Without real data, any allocation is a hypothesis. Making the AI state its assumptions explicitly means you can challenge them ("we don't actually close winter emergencies at 2× the rate of summer ones") and adjust.
"Keep Some Budget for Testing"
Pure optimization starves new campaigns before they can prove themselves. Reserving a test bucket keeps the account from ossifying around its current winners.
Priority Services as Input
Sometimes the business reason for funding a campaign outweighs the SEM metrics (strategic new offering, customer acquisition for a flagship product). Naming priorities in context lets the AI respect that.
Example Output
| Campaign | Budget Share | Why | Notes |
|---|---|---|---|
| Emergency Services | 40% | Highest urgency and strongest likelihood of immediate conversion. | Exact and phrase match only. Call asset required. |
| Standard Plumbing | 30% | Larger service set, lower urgency. Covers drain, water heater, fixtures. | Good bucket for smart bidding once conversion data matures. |
| Remodeling & Install | 20% | Higher ticket, longer cycle — allocate less but maintain presence. | Pair with a lead form; phone calls underperform for this intent. |
| Test / New Offerings | 10% | Keeps the account learning and can absorb future seasonal shifts. | Review monthly; graduate winners into their own campaign. |
Assumptions:
Emergency campaigns convert at roughly 2× the rate of standard campaigns; remodeling has long sales cycles that should not be starved even at lower conversion rate; a 10% test reserve is appropriate for a maturing account.
Tips for Better Results
Feed In Historical CPA
Once you have 30 days of conversion data, paste each campaign's CPA alongside its theme. The allocation gets much sharper.
Challenge Every Assumption
The AI will confidently state assumptions it can't verify. Cross-check each one before locking in the allocation.
Rebalance Monthly
Run this prompt at the end of every month with the previous month's performance data. Share-of-budget should move as results evolve.
Cap High-Risk Campaigns
If a campaign's allocation feels unsafe, cap its daily budget in Google Ads itself — don't rely on planned share-of-budget to prevent overspend.
