The Google Ads Script Bible: 152 Scripts to Automate Your PPC Campaigns

Every Google Ads manager reaches the same point: too many campaigns, too many manual tasks, and not enough hours. You are checking budgets, pausing underperformers, pulling reports, adding negative keywords, and monitoring quality scores — all before you even get to strategy.

Google Ads scripts solve this problem. They let you automate repetitive tasks using JavaScript that runs directly inside your Google Ads account. No external tools. No APIs to configure. Just paste a script, set a schedule, and let it run.

I have compiled 152 Google Ads scripts across 11 categories — the most comprehensive collection available anywhere. In this post, I am giving away the top 10 scripts every PPC manager needs, with full details on what they do and how to implement them. If you want the complete library of all 152, you can download the full PDF at the bottom of this post.

Why Google Ads Scripts Matter in 2026

Manual campaign management does not scale. Whether you are managing a single account spending $5,000 a month or an agency portfolio burning through $500,000, the operational work is the same. Scripts handle the grunt work so you can focus on what actually moves the needle: strategy, creative, and growth.

Here is what scripts give you:

• Time savings: Automate tasks that would take hours every week, from budget monitoring to negative keyword management
• Faster response times: Get alerts within minutes when performance drops, budgets deplete, or ads get disapproved
• Consistency: Scripts do not forget, skip steps, or get distracted. They run the same checks every single time
• Scale: Apply optimizations across hundreds of campaigns simultaneously instead of doing it one by one

The 10 scripts below are the ones I consider essential for any serious PPC operation. They cover the core areas: bidding, budgets, quality, maintenance, reporting, and monitoring.

The Top 10 Google Ads Scripts You Need Right Now

1. Advanced Ad Scheduling Script

Category: Bidding | Source: Brainlabs

The default ad scheduling in Google Ads gives you basic day-parting options. This script goes far beyond that. It enables flexible bidding based on any minute of any day on any device, giving you granular control over bid adjustments by both time and device.

Why it matters: Most accounts have wildly different performance at different times. A B2B SaaS company might convert at 3x the rate during business hours compared to evenings. An ecommerce brand might see mobile conversions spike during commute hours. This script lets you capture those patterns and bid accordingly, which can reduce wasted spend by 15-30% in many accounts.

How to implement: Install the script from the Brainlabs GitHub repository. Configure your bid multipliers in a Google Sheet, specifying the adjustment for each hour block and device type. Set the script to run hourly.

2. Performance-Based Budget Allocation Script

Category: Budget Management

This script automatically redistributes budget from underperforming campaigns to high-performing ones based on CPA or ROAS. Instead of manually shifting budgets every few days, the script monitors performance in real time and makes the moves for you.

Why it matters: Budget misallocation is one of the biggest profit killers in Google Ads. You might have a campaign crushing it at a $15 CPA while another one burns cash at $80 CPA, and both are getting equal budget. This script fixes that imbalance automatically, typically improving overall account ROAS by 10-25%.

How to implement: Define your target CPA or ROAS for each campaign. Set minimum and maximum budget thresholds so no campaign gets starved or overloaded. Schedule the script to run every 4-6 hours to give campaigns enough data between adjustments.

3. Quality Score Monitor

Category: Quality Score and Performance

Tracks quality score changes across your entire account and alerts you when scores decline significantly on high-performing keywords. It logs historical quality score data so you can spot trends over time rather than reacting to snapshots.

Why it matters: Quality score directly impacts your cost per click and ad rank. A keyword dropping from QS 8 to QS 5 can increase your CPC by 50% or more. Most managers do not notice these drops until they have already lost money. This script catches them early so you can investigate the cause and fix it before it compounds.

How to implement: Set up a connected Google Sheet to store historical QS data. Configure alert thresholds (for example, alert when any keyword with more than 100 clicks per month drops by 2 or more points). Schedule the script daily and route alerts to your email or Slack via webhook.

4. Negative Keyword Manager

Category: Maintenance | Source: Brainlabs

Automatically reviews your search term reports and adds irrelevant terms as negative keywords. You define the rules — minimum spend with zero conversions, irrelevant categories, brand terms that should be excluded from generic campaigns — and the script enforces them continuously.

Why it matters: Wasted spend on irrelevant search terms is the silent killer of PPC profitability. In a typical account, 20-40% of search terms are irrelevant. Most managers review search terms weekly at best, which means days of wasted spend before action is taken. This script reviews terms every time it runs and takes immediate action.

How to implement: Create a Google Sheet with your negative keyword rules: minimum spend threshold before flagging, explicit exclusion terms, and the negative keyword lists to add them to. Configure the script to run every 6 hours for active accounts.

5. Daily Performance Report Generator

Category: Reporting | Source: Brainlabs

Generates automated daily reports with all key metrics — spend, clicks, impressions, conversions, CPA, ROAS — and delivers them via email. Reports are formatted with comparison periods (yesterday vs. same day last week, week-over-week, month-over-month).

Why it matters: Building reports manually eats up 2-5 hours per week for most PPC managers. This script generates them automatically before you even open your laptop in the morning. It also ensures nothing slips through the cracks — you will see anomalies in your daily numbers immediately rather than discovering them during a weekly review.

How to implement: Configure the script with your preferred metrics, comparison windows, and email recipients. Use the Google Sheets template to customize the report format. Schedule it to run at 7 AM daily so reports are ready when you start work.

6. Disapproved Ads Monitor

Category: Monitoring and Alerts | Source: Brainlabs

Tracks all ad disapprovals in your account and sends instant notifications for urgent review. It categorizes disapprovals by type (policy violation, trademark issue, landing page problem) and prioritizes them by the impact on campaign performance.

Why it matters: A disapproved ad in a high-volume ad group can cost you thousands in lost revenue before you notice. Google does not always send email notifications for disapprovals, and when they do, they often get buried. This script catches every disapproval the moment it happens and tells you exactly which campaign, ad group, and ad is affected — plus the reason.

How to implement: Install the script and configure your notification preferences (email, Slack, or both). Set priority levels based on campaign daily spend so high-value disapprovals get flagged immediately. Run the script every 2 hours.

7. Weather-Based Bidding Script

Category: Bidding

Automatically increases or decreases bids based on real-time weather conditions in your target locations. It pulls weather data via API and applies bid multipliers you define for different conditions (rain, sunshine, temperature ranges, and more).

Why it matters: Weather has a massive impact on buying behavior in many industries. HVAC companies see search volume spike during heat waves. Umbrella retailers convert better when it rains. Restaurants get more delivery orders in bad weather. This script lets you capitalize on those patterns automatically instead of scrambling to adjust bids when the weather changes.

How to implement: Connect a weather API (OpenWeatherMap has a free tier). Define your bid multipliers in a Google Sheet: which weather conditions increase or decrease bids, and by how much. Map your Google Ads locations to weather API location codes. Schedule the script to run every 2-4 hours.

8. Expired Landing Pages Finder

Category: Maintenance

Scans all active ads in your account and checks whether the landing pages return proper HTTP responses. It identifies pages returning 404 errors, 500 server errors, redirect chains, or pages that have been taken down, and alerts you immediately.

Why it matters: Sending paid traffic to broken pages is literally throwing money away. It also tanks your quality score, which increases CPCs across the board. In large accounts with hundreds of landing pages, broken links are almost inevitable as products get discontinued, pages get restructured, or domains change. This script catches broken pages before they drain your budget.

How to implement: The script iterates through all enabled ads, extracts final URLs, and checks each one. Configure it to alert on any non-200 HTTP response code. Set up automatic pausing for ads with confirmed broken pages (optional) and run it daily.

9. Click Fraud Monitor

Category: Monitoring and Alerts

Detects unusual click patterns that may indicate fraudulent activity. It monitors metrics like click frequency from specific IPs, abnormal CTR spikes, and geographic anomalies where clicks do not match your target market.

Why it matters: Click fraud costs advertisers billions every year. While Google has built-in invalid click detection, it does not catch everything — especially sophisticated competitors or bot networks. This script adds an extra layer of monitoring and alerts you when patterns deviate from normal behavior, so you can investigate and add IP exclusions or adjust targeting before significant budget is wasted.

How to implement: Define your baseline metrics: normal CTR ranges, expected geographic distribution, and acceptable click-to-conversion ratios. The script flags deviations that exceed your thresholds. Configure email alerts and review flagged activity weekly. Schedule the script to run every 4 hours.

10. Conversion Drop Alert

Category: Monitoring and Alerts

Identifies sudden drops in conversion rates or conversion volume across campaigns, ad groups, and keywords. It compares current performance against rolling averages and alerts you when conversions fall below expected thresholds.

Why it matters: Conversion drops can happen for dozens of reasons: a broken form, a tracking tag that stopped firing, a landing page change, a competitor undercut on price. The problem is that most managers do not notice until the end-of-week or end-of-month report. This script catches the drop within hours, giving you time to diagnose and fix the issue before it burns through significant budget.

How to implement: Set your comparison window (typically 7-day rolling average vs. today). Define the percentage drop that triggers an alert (e.g., 30% below average). Configure alerts for both conversion rate drops and absolute conversion count drops. Run the script every 6 hours.

How to Install Google Ads Scripts

If you have never used scripts before, the setup process takes about 2 minutes:

1. Open your Google Ads account and navigate to Tools, then Bulk Actions, then Scripts
2. Click the blue plus button to create a new script
3. Authorize the script to access your account when prompted
4. Paste the script code into the editor
5. Configure any variables at the top of the script (thresholds, email addresses, spreadsheet URLs)
6. Preview the script to test it without making changes
7. Set a schedule (hourly, daily, weekly) and save

Most scripts connect to a Google Sheet for configuration and output. This keeps the script code clean and lets you adjust settings without editing the code itself.

Best Practices for Google Ads Scripts

Start with monitoring scripts before automation scripts. Get comfortable with alerts and reports before letting scripts make bid or budget changes automatically. This gives you visibility into what the scripts would do before they do it.

Always use preview mode first. Every script has a preview option that shows you what changes it would make without actually making them. Use this every time you install a new script or change settings.

Set conservative thresholds initially. If a script pauses keywords below a certain performance level, start with a generous threshold and tighten it over time. You can always make scripts more aggressive later, but undoing automated changes is painful.

Monitor script execution logs. Scripts can fail silently if they hit API limits, encounter errors, or run into authorization issues. Check your script logs weekly to make sure everything is running as expected.

Layer scripts gradually. Do not install 20 scripts at once. Start with 2-3 essentials (like the daily report, disapproved ads monitor, and negative keyword manager), get them running smoothly, then add more over time.

Frequently Asked Questions

Are Google Ads scripts free to use?

Yes. Google Ads scripts are a built-in feature of Google Ads at no additional cost. You can create and run scripts directly in any Google Ads account. Some scripts connect to external APIs (like weather data) that may have their own free tiers or costs, but the scripting functionality itself is completely free.

Do I need to know JavaScript to use Google Ads scripts?

Not necessarily. Many scripts are available as ready-to-use templates that you can copy and paste. You just need to configure the variables at the top (like email addresses, thresholds, and spreadsheet URLs). However, basic JavaScript knowledge helps if you want to customize scripts or troubleshoot issues.

Can scripts break my Google Ads account?

Scripts can make changes to your account, so it is important to use preview mode before enabling any script that modifies bids, budgets, or campaign status. Start with read-only scripts (reports and alerts) and graduate to automation scripts once you are comfortable. Always set conservative thresholds and check execution logs regularly.

How many scripts can I run at the same time?

Google Ads allows up to 50 scripts per account. Each script can run for a maximum of 30 minutes per execution. For most accounts, 10-15 active scripts cover all the essential automation needs. The key is choosing scripts that complement each other without creating conflicts (for example, two scripts trying to adjust bids on the same keywords).

Will scripts work with Smart Bidding and Performance Max campaigns?

Scripts have limited interaction with Smart Bidding strategies and Performance Max campaigns because Google manages the bidding automatically. However, scripts are still valuable for monitoring, reporting, alerts, and budget management on these campaign types. You can track performance, detect anomalies, generate reports, and manage budgets even when Google handles the bidding.

Stop Managing Campaigns Manually

The difference between PPC managers who scale and those who burn out is automation. Scripts handle the repetitive work so you can focus on strategy, creative testing, and growth.
