Budget Pacing
Budget pacing is how evenly a campaign spends its budget across its flight dates. Pacing alerts warn when spend is tracking toward overspend or underdelivery — ideally forecast-based, so the warning arrives while there's still time to act.

Budget pacing is how evenly a campaign spends its budget across its intended flight. Pacing ahead means the budget exhausts early (overspend risk); pacing behind means underdelivery. Pacing alerts exist to surface both while there's still time to fix them — the difference between a mid-month correction and a month-end surprise.
Why pacing breaks silently
Platform automation reallocates spend continuously — Advantage+ campaign budget on Meta, Performance Max and Smart Bidding on Google — and a budget approval or bid change can shift delivery within hours. A campaign that paced perfectly for three weeks can be tracking 30% hot days after one edit, and nothing on a dashboard announces it.
Threshold vs. forecast-based pacing alerts
| Threshold ("80% spent") | Forecast-based | |
|---|---|---|
| What it tells you | Where spend is now | Where spend will land at flight end, at current trajectory |
| When you find out | After the problem is most of the way in | While the correction is still cheap |
What good pacing monitoring includes
Projection to flight-end at current trajectory, per-campaign and per-account rollups across platforms, alerts pushed where the team works (Slack), and — when pacing breaks — the change that broke it, from the account's change record.
