Monitors your account for unexpected performance deviations by comparing today's stats against historical averages for the same weekday. Sends an alert email when impressions, clicks, conversions, or cost deviate beyond configurable thresholds.

One 0-100 score for the whole account, built from seven objective checks — tracking flatlines, disapprovals, serving status, budget losses, negative coverage and query hygiene — with the deduction breakdown as your fix list.
Finds the structural gaps that stop ad groups from serving: ad groups without active ads, without an RSA, without keywords, keyword-stuffed themes, and multi-RSA ad groups.
Generates a daily at-a-glance performance overview of your entire Google Ads account. Writes prior-day stats to a Google Sheet with running history and optionally emails a formatted comparison of yesterday vs. two days ago vs. one week ago.
Generates a Google Spreadsheet with ad performance stats segmented by headline and final URL, including distribution charts. Covers all ad types and optionally emails the report link weekly.
Maps every campaign's ad schedule and flags forgotten narrow serving windows, stale schedule bid modifiers that Smart Bidding ignores, and (optionally) campaigns running 24/7.
Sends customized Slack and email alerts when metric anomalies are detected across your account, with thresholds and rules defined in a Google Sheet. Supports MCC.
Account Anomaly Detector compares today's account performance, up to the current hour, against the average of the same weekday over the past few weeks. When impressions, clicks, or conversions fall below your thresholds — or cost rises above yours — it logs the anomaly and (if an email is set) sends an alert. Self-contained: no companion spreadsheet needed.

Self-contained — no companion spreadsheet required (the original Google template needed one). It compares only the hours of the day that have elapsed against the same hours on the same weekday in prior weeks. Schedule daily rather than hourly to avoid repeat alerts.
