}За този script
Conversion Drop Detector compares campaign conversion volume between the last 7 days and the previous 7 days. It highlights statistically meaningful drops so teams can react faster to broken tracking, creative fatigue, auction shifts, or site issues.
The script calculates drop percent and includes spend context for both windows to avoid overreacting to low-volume noise.
It writes outputs to Google Sheets with the same resilient behavior: blank URL creates a new sheet, provided URL writes into existing sheet and creates missing tab.
Implementation notes
- Set MIN_PREV_CONVERSIONS and MIN_DROP_PERCENT to reduce false positives.
- Leave SPREADSHEET_URL blank to auto-create, or provide an existing URL.
- Run manually first to verify signal quality for your account size.
- Schedule daily or 2-3x weekly for early decline detection.
