Download a ready-to-use budgeting template and cadence guide for week-based promotions using Google’s 2026 total campaign budgets.

Stop tweaking daily budgets for every short promotion — use a single total budget and a week-based cadence that works

If you run frequent week-long promotions, flash sales, or limited-time offers, you know the daily budgeting grind: manual daily caps, missed opportunities on peak days, and scramble to avoid underspend. Google’s January 2026 expansion of total campaign budgets from Performance Max to Search and Shopping gives marketers a new lever: set a total campaign budget across days or weeks and let Google optimize pacing automatically. This article gives a practical, downloadable budget template and a clear cadence guide so you can plan, predict, and measure week-based promotions with confidence.

Why this matters in 2026

Short, timeboxed promotions dominate modern marketing calendars. In late 2025 and early 2026, marketers responded by consolidating budgets and relying on platform-level pacing to reduce operational overhead. Google’s rollout (open beta as of Jan 15, 2026) of total campaign budgets for Search and Shopping is a pivotal update: instead of setting a daily budget and micromanaging, you can define a total campaign budget and a date range, then let Google's algorithms optimize delivery to use the budget by the end date.

This matters because it changes how you plan spend: you move from daily control to total-outcome planning. That reduces manual work, but it requires an upfront budgeting plan and a cadence that matches promotional objectives. Below, you’ll get a ready-to-use template design, formulas, and a week-based cadence guide for high-conversion short campaigns.

Quick primer: How total campaign budgets change your workflow

Plan at the campaign level: Decide the total spend for the promotion, not just a daily cap.
Let the platform pace: Google optimizes impressions across the date range to spend the total budget efficiently.
Align bidding strategy: Use conversion-focused bidding (tROAS, Maximize Conversions) and set guardrails (target CPA or ROAS) to keep performance predictable.
Monitor fewer levers: Fewer daily manual changes but more emphasis on pre-launch modeling and mid-campaign diagnostics.

Downloadable template overview — what to build

The template has two tabs: Campaign Plan and Pacing Grid. Build these in Google Sheets so you can copy formulas and export CSV for your MSSP or analytics team.

Campaign Plan tab (columns and formulas)

Use these columns in row 2+; row 1 is header row. Formulas assume dates in ISO format.

Campaign Name — text
Start Date — date
End Date — date
Total Budget — currency (e.g., $10,000)
Days — formula: =DAYS(End Date, Start Date) + 1
Avg Daily Budget (simple) — formula: =Total Budget / Days
Primary KPI — e.g., Conversions, Revenue, ROAS
Target CPA / tROAS — numeric
Notes — e.g., creative variations, high-peak days

These fields give you the high-level view. The Pacing Grid handles daily detail and weightings.

Pacing Grid tab (daily detail and weighting)

Columns per campaign, one row per day. Include formulas so totals update when you change total budget or weights.

Date
Day Number — incremental (1..N)
Week Number — helpful for longer promotions
Base Daily — =Total Budget / Days (pull from Campaign Plan)
Day Weight — multiplier (default 1.0). Use 1.2 for peak days, 0.8 for slow days.
Weighted Daily Budget — =Base Daily * Day Weight
Normalized Daily — To ensure total equals Total Budget, calculate a normalization factor: =Total Budget / SUM(Weighted Daily for campaign range). Then Normalized Daily = Weighted Daily * Normalization Factor.
Cumulative Spend Target — running total of Normalized Daily
Actual Spend (import) — fill from daily cost reports
Variance — Actual Spend minus Normalized Daily (or minus Cumulative target)

Normalization is the key: it preserves your weighting intentions while guaranteeing the plan uses the precise Total Budget by the end date. For tactical teams running pop-ups or in-person activations, combine this grid with a compact field kit checklist so on-the-ground spend and staffing match your daily targets.

Three pacing models and when to use them

1) Evenly paced (default)

Best for brand awareness or when conversion probability is stable across days. Set all Day Weights = 1.0. Use when you expect consistent daily performance and want predictable CPA.

2) Front-loaded (early surge)

Use for launches, limited stock items, or when early momentum creates urgency. Set higher weights on days 1–3 (e.g., 1.5, 1.3, 1.1) and taper later days (0.8–0.9). This works when early sales create social proof or when you want quick learnings for creative/bid optimizations. See the micro-drops & flash-sale playbook for similar front-loaded tactics and conversion protections.

3) Weighted-by-day (weekday vs weekend)

Good for retail or B2C where weekends outperform weekdays, or for B2B where Monday is strongest. Create multipliers based on historical day-of-week conversion rates. Example: Mon–Thu = 0.9, Fri = 1.1, Sat = 1.3, Sun = 1.0. Normalize to keep total spend fixed. If you're shipping goods during a short promotion, coordinate your logistics plan with micro-fulfilment and packaging playbooks to avoid stockouts when you front-load traffic.

Sample scenario: 7-day flash sale ($20,000 budget)

Campaign length: 7 days. Total Budget: $20,000. Days: 7. Base Daily = $2,857.14.

Front-loaded weights (example): Day 1 1.6, Day 2 1.3, Day 3 1.1, Day 4 1.0, Day 5 0.9, Day 6 0.7, Day 7 0.4. Sum of weighted = 6.0 (example). Normalization factor = 20,000 / (Base Daily * 6.0) = 20,000 / (2,857.14 * 6) = ~1.1667. Normalized Day 1 = 2,857.14 * 1.6 * 1.1667 = ~$5,333 (approx). For tactical guidance on running flash sales and converting sudden traffic into repeat buyers, pair this approach with a short-form content burst and local live channels from a rapid edge content playbook.

This ensures Day 1 gets a meaningful burst while total spend equals exactly $20,000 by campaign end.

How to set a total campaign budget in Google Ads (step-by-step)

Open Google Ads and choose the campaign you plan to run as a timeboxed promotion.
Go to Settings > Budget. Select "Total campaign budget" (available in Search and Shopping as of Jan 2026 beta).
Enter the Total Budget and select start and end dates. Confirm the date range matches your template.
Choose a bid strategy aligned to your KPI: Maximize Conversions with a target CPA or Target ROAS if revenue-centric. Use Target Impression Share only for awareness-driven bursts.
Set conversion tracking and conversion windows that match your campaign’s sales cycle. Ensure tracking is validated before launch.
Consider using ad scheduling and asset-level experiments if you want to restrict ads on certain days, but avoid fine-grained daily budgets—use the template’s weights instead.

Performance guardrails and risk controls

Even with total budgets, you’ll want guardrails: target CPA/tROAS limits, negative keyword lists, location bid adjustments, and audience exclusions. Because Google will optimize pacing automatically, these constraints prevent undesired overspend on low-value queries.

Target CPA / tROAS: Set realistic targets derived from historical data. Tight targets restrict pacing; looser targets allow the engine to find volume.
Budget pacing alerts: Use Sheets scripts or platform alerts to warn if actual cumulative spend deviates >10% from target pacing on day 1–3.
Negative keywords: Pre-load the list to protect against irrelevant spend spikes.

Cadence guide: Pre-launch → Live → Post-campaign (7-day promotion example)

Pre-launch (D-14 to D-1)

D-14: Finalize total budget and build the Campaign Plan tab. Confirm creative assets and landing pages.
D-10: Run creative A/B tests at low spend or use dynamic assets to collect early signals.
D-7: Load Negative Keyword list and block low-intent placements. Validate conversion tracking in test environment.
D-3: Freeze major changes. Ensure Google Ads conversion modeling is active if signal gaps exist.

Live (Day 1–7)

Day 0 (launch): Confirm total campaign budget and start/end dates in Google Ads. Double-check bidding strategy.
Day 1: Expect higher volatility. Focus on data quality (conversion recording, invalid click monitoring). Do not change total budget unless absolutely necessary.
Day 2–3: Check pacing variance. If cumulative spend is well below the plan and performance is strong, consider raising target CPA slightly or relaxing constraints rather than manually increasing budgets.
Day 4–5: Use creative insights to swap underperforming assets. If variance is within acceptable bounds (<10%), avoid changes that could reset learning.
Day 6–7: If you are ahead of spend but under target CPA, reallocate to higher-performing audiences or increase ROAS targets to protect efficiency.

Post-campaign (D+1 to D+14)

D+1: Export final performance and reconcile against template actuals. Calculate CPA, ROAS, conversion lift.
D+3: Run attribution checks—look for assisted conversions and cross-device effects.
D+7–D+14: Create net-new learnings and update day-of-week multipliers for future campaigns. Feed results into your model for improved forecast accuracy and operations notes from micro-fulfilment.

Measurement tips and 2026 trends

In 2026, measurement increasingly relies on aggregated modelling and platform-driven signals. Two important trends matter for timeboxed promotions:

1) Aggregated conversion modeling: As privacy-safe approaches continue, Google’s modeled conversions help fill gaps. Ensure conversion goals are prioritized in the campaign so models align with your commercial objectives.
2) Short-burst optimization techniques: Publishers and ad platforms optimize differently for short campaigns. Expect higher variance but faster learning. Use front-loaded tests when you need quick creative validation. For teams running live commerce or in-person activations, coordinate pacing with live-stream plans from live-stream shopping guides.

Combine these with post-campaign incrementality tests (holdout groups when possible) to measure true lift. The Escentual.com example from early 2026 — a UK retailer that used Google’s total campaign budgets during promotions — reported a 16% increase in traffic without exceeding budget while maintaining ROAS. This type of result is typical when planners combine a clear total-budget model with strong measurement discipline.

Automation and integration suggestions

Even though Google will pace spend, automation helps you monitor and react faster. Recommended automations:

Sheets automation: Use Apps Script to pull daily cost and conversions from the Ads API and compare to the Pacing Grid.
Alerting: Slack or email alerts if variance > 15% after Day 2.
Creative swapping: Automate asset rotation based on early CTR and conversion signals (via Ads API or creative management platforms).
Attribution hooks: Export campaign-level click IDs to your analytics warehouse and use server-side reconciliation for more accurate ROAS.

Common mistakes and how to avoid them

Changing total budget mid-flight: Avoid unless performance is catastrophically off. A single change can disrupt pacing algorithms.
Setting unrealistic CPA/tROAS: If your target is too tight, the engine may underdeliver—leaving budget unspent.
Ignoring normalization: If you apply day weights but don’t normalize, you risk under- or overspending vs the total budget.
Neglecting measurement: Don’t assume delivered conversions equal incremental sales. Use control groups where possible. For event teams and retail pop-ups, keep a field-level playbook to reconcile in-person and online metrics (field toolkit).

Forecasting: a simple algorithm you can use

To forecast daily volumes and expected conversions for a timeboxed promotion, use this simple approach:

Estimate baseline conversion rate (CR) from historical similar promotions.
Estimate CPC or average cost per click (CPC) for target keywords (use last 90-day average).
Compute expected clicks per day = Normalized Daily / CPC.
Compute expected conversions per day = Clicks per day * CR.
Sum across days for total forecast; refine with day-of-week multipliers.

This lets you translate spend into expected outcomes quickly and supports target CPA/tROAS setting in Google Ads.

How to adapt over time (continuous improvement)

After each promotion, update your template’s day-of-week multipliers and CPC/CR baselines. Maintain a library of promotion types (clearing sale, new product launch, holiday offer) and their optimal pacing templates. Over time you’ll build a catalogue that reduces planning time and improves outcomes. If you're running a series of short promotions, merge these learnings into an operational playbook for live events and pop-ups (community commerce and local activation guides are helpful references).

Next steps — use the template and cadence guide

To start: recreate the two-tab template in Google Sheets using the column layout above, paste in your campaign dates and total budgets, and choose a pacing model. Run one promotion using the total campaign budget feature in Google Ads (Jan 2026 rollout) and compare your actuals to the Pacing Grid. Expect initial variance but use the first three promotions to calibrate day weights. For teams coordinating in-person activation or merch rollouts, align your budget plan with vehicle or roadshow logistics (merch roadshow playbooks) and packaging plans (micro-fulfilment).
