Overview

Budget Pacing Monitor runs on a schedule (every 2 hours) and compares each enabled campaign's actual spend against the proportional target for the current time of day. It logs campaigns that are significantly over- or under-pacing and can optionally pause overspenders automatically to protect your daily budget cap.

Setup

1Open your Google Ads account and go to Tools & Settings → Scripts.
2Click the + button to create a new script and paste the code below.
3Set PAUSE_OVERSPENDING = true if you want campaigns to be auto-paused when they exceed the overspend threshold.
4Adjust OVERSPEND_THRESHOLD (default 1.20 = 120%) and UNDERSPEND_THRESHOLD (default 0.50 = 50%) to suit your tolerance.
5Schedule the script to run every 2 hours (or more frequently for high-budget accounts).

Notes

This script only reads campaign budgets, not shared budgets. Campaigns using a shared budget will report the shared budget amount, which may not reflect actual per-campaign allocation.
