5 Google Ads Scripts Every Agency Should Run in 2026
After 13 years of managing Google Ads accounts and writing scripts for agencies of all sizes, these are the five automations I consider non-negotiable. They save hours every week and catch problems before clients notice them.
1. Placement Cleaner (Display & PMax)
If you run Display or Performance Max campaigns, bad placements are silently eating your budget. Mobile game apps, parked domains, kids' YouTube channels β Google's targeting is broad by design.
A placement cleaner script checks your placement reports daily and automatically excludes URLs and apps that waste money. At the MCC level, it can protect all client accounts at once.
Get it free: PMax Placement Cleaner handles Performance Max, and Placement Exclusion Manager covers Display β install either in one click.
Impact: Agencies typically see 5-15% budget savings in the first month after deploying this script.
2. Search Term Mining & Negative Keywords
Search term reports grow every day, and no human can review them all across 50+ accounts. A script that runs daily, flags irrelevant search terms, and adds them as negatives keeps your accounts clean without manual effort.
The best versions use n-gram analysis β looking at 1-word, 2-word, and 3-word patterns β to find systemic issues rather than just individual bad queries.
Get it free: the Search Term Harvester surfaces converting queries worth adding, and the Search Term N-Gram Analyzer exposes the systemic waste patterns behind them.
Impact: Reduces wasted spend by 3-10% and improves Quality Scores over time.
3. Budget Pacing
Nothing frustrates a client more than running out of budget on the 20th of the month β or underspending by 30%. A budget pacing script tracks daily spend against monthly targets and adjusts campaign budgets to stay on track.
Smart versions account for day-of-week performance patterns: spend more on high-converting Tuesdays, less on slow Sundays.
Get it free: the Budget Pacing Monitor tracks spend against monthly targets, and Flexible Budgets shifts daily budgets to match your performance calendar.
Impact: Keeps monthly spend within 2-5% of target, every month.
4. Disapproved Ad & Product Monitoring
Google can disapprove ads or products at any time, and the notifications are easy to miss β especially across many accounts. A monitoring script checks for newly disapproved items daily and sends alerts to your team.
For Shopping and PMax campaigns, this is critical. A disapproved product means zero impressions for that product, and it can take days before anyone notices.
Get it free: the Disapproved Ads Monitor watches your ads, and Newly Disapproved Products catches Shopping and PMax feed rejections.
Impact: Catches disapprovals within hours instead of days, preventing revenue loss.
5. Anomaly Detection Alerts
This is your early warning system. The script compares today's metrics (spend, clicks, conversions, CPA) against historical averages and alerts you when something is significantly off.
A 50% drop in conversions on a Tuesday? That is probably a tracking issue, not a performance dip. A sudden spike in CPC? Competitor entered the auction. These scripts catch problems that dashboards miss because nobody watches dashboards 24/7.
Get it free: the Account Anomaly Detector compares today's spend, clicks, conversions, and CPA against historical norms and alerts you when something breaks.
Impact: Turns reactive firefighting into proactive management.
Running These at Scale
The challenge with all five scripts is deployment. Writing them once is the easy part. Deploying them to 50 accounts, keeping versions in sync, and monitoring their execution β that is where it gets messy.
This is exactly why we built chiliad. Install a script once, deploy it to every account with one click, and monitor all executions from a single dashboard. No more copy-pasting.
Every script linked above lives in the chiliad marketplace β free to install, one click each, and updated automatically when we ship improvements. Browse the full library of 100+ scripts while you are there.
