Systematically validates all URLs across ads, keywords, and sitelinks by making HTTP requests and checking for error responses. Uses labels to track progress across runs, enabling large accounts to be checked in chunks without re-testing already-verified URLs.

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.
Link Checker fetches the final and mobile URLs of your ads, keywords, and campaign sitelinks and flags any that return an unexpected HTTP code (or whose page contains a failure string). Broken URLs are logged, emailed, and appended to an auto-created Google Sheet. A tracking label records which entities have been checked, so large accounts complete across multiple runs; once a full pass finishes the label is cleared and the next run starts fresh. It only adds/removes its own label — it never changes your ads.

BROKEN [404] https://example.com/old-page (Ad: Summer Sale) BROKEN [failure string: Out of stock] https://example.com/sku/123 (Keyword: running shoes) === Link Checker: 2 broken URL(s) this run === Emailed report to you@example.com All URLs checked — tracking label cleared; next run starts a fresh cycle.
The only write to your account is its own tracking label; URLs are never modified. ValueTrack parameters ({ifmobile:...}, {keyword}, etc.) are stripped before fetching. The failure-string check downloads each page, so it is slower — leave FAILURE_STRINGS blank to check HTTP codes only. Run the script (not preview) at least once so it can create the label.
