}За този script
Campaign Spend Spike Monitor compares last 7 days spend against prior 7 days and flags campaigns with sharp increases. It helps identify budget leakage, targeting drift, or auction changes before they materially impact performance.
The script includes conversion context and growth percentages to separate healthy scale-up from risky overspend.
Like your other scripts, sheet output is resilient: blank URL creates a new spreadsheet; provided URL writes to existing spreadsheet and creates the tab if needed.
Implementation notes
- Set MIN_RECENT_COST and MIN_SPIKE_PERCENT for your account scale.
- Run manually and tune thresholds to avoid low-volume noise.
- Review flagged campaigns for query shifts, targeting expansion, and budget/bid changes.
- Schedule daily or 3x weekly for anomaly detection.
