Google Ads Scripts let advertisers automate repetitive campaign management tasks using JavaScript code that runs directly inside the Google Ads platform — no external tools, APIs, or servers required. For Indian PPC managers handling multiple client accounts with budgets ranging from ₹50,000 to ₹50,00,000 per month, Ads Scripts can automate bid adjustments, budget pacing, quality score monitoring, negative keyword management, and custom reporting, saving 10–20 hours per week of manual work.

What Are Google Ads Scripts and How Do They Work?
Google Ads Scripts are JavaScript programs that run inside your Google Ads account to read data, make changes, and interact with external services. Key features:
- No coding environment needed: Scripts run in the Ads interface under Tools → Bulk Actions → Scripts.
- Scheduled execution: Run scripts hourly, daily, weekly, or monthly.
- Read and write access: Scripts can read campaign data, modify bids, pause/enable ads, add negative keywords, and send email alerts.
- External data access: Fetch data from Google Sheets, external APIs, and URLs using UrlFetchApp.
- MCC scripts: Run a single script across all accounts in a Google Ads Manager (MCC) account.
Essential Google Ads Scripts for Indian Advertisers
1. Budget Pacing Monitor
This script checks daily spend against the monthly budget target and sends email alerts if spending is ahead or behind pace. Critical for Indian clients with strict monthly budgets where overspending is not acceptable.
The script calculates: (total spend so far / days elapsed) vs (monthly budget / total days in month). If the daily run rate exceeds 120% of target, it sends an alert. If it falls below 80%, it sends a different alert suggesting bid increases.
2. Quality Score Tracker
Google Ads does not provide historical quality score data natively. This script logs quality scores for all keywords to a Google Sheet daily, creating a historical record that shows trends over time. This is invaluable for identifying quality score drops that impact CPC and position.
The script iterates through all active keywords, records the current quality score, expected CTR, ad relevance, and landing page experience, and appends a new row with the date. Over weeks and months, this data reveals which keywords are improving or degrading.
3. Automated Negative Keyword Mining
This script analyses search term reports, identifies irrelevant terms that triggered your ads, and automatically adds them as negative keywords. It filters for search terms with impressions but zero conversions, or terms with CTR below a threshold. For Indian campaigns, this catches irrelevant terms in Hindi transliterations and misspellings that human review often misses.
4. Broken URL and 404 Checker
Ads pointing to 404 pages waste budget and hurt quality score. This script checks all active ad URLs daily and pauses ads with broken landing pages, sending an immediate email alert. Essential for ecommerce advertisers whose product URLs change frequently.
5. Bid Adjustment by Time of Day and Day of Week
This script analyses conversion data by hour and day, then applies bid modifiers automatically. For many Indian B2B advertisers, conversions peak between 10 AM–1 PM and 3 PM–6 PM IST on weekdays. The script increases bids during peak hours and decreases them during low-conversion periods (late night, early morning, weekends).
How to Write and Deploy a Google Ads Script
- Access the script editor: Go to Tools & Settings → Bulk Actions → Scripts → New Script.
- Write or paste your script: Scripts use Google Ads JavaScript API, which provides objects like AdsApp.campaigns(), AdsApp.keywords(), AdsApp.ads(), and reporting functions.
- Authorise: Click “Authorise” to grant the script access to your account data.
- Preview: Always run in Preview mode first. Preview shows what changes the script would make without actually applying them. This is critical — a buggy script can pause all your campaigns or change thousands of bids incorrectly.
- Schedule: Set the frequency (hourly for bid scripts, daily for reporting, weekly for negative keyword mining).
- Monitor: Check script execution logs regularly. Scripts can fail silently if API quotas are exceeded or data formats change.
Advanced Script Techniques
Connecting to Google Sheets
Google Sheets integration allows scripts to read configuration (bid rules, budget targets, keyword lists) and write output (reports, logs, alerts). Use SpreadsheetApp.openByUrl() to connect. This is how most Indian agencies manage multi-client scripts — each client has a configuration sheet.
MCC-Level Scripts for Agencies
If you manage 20+ client accounts under an MCC, MCC scripts iterate through all child accounts and apply the same logic. This is how agencies automate budget pacing and reporting across their entire portfolio. The script uses MccApp.accounts() to loop through accounts.
External API Integration
Use UrlFetchApp.fetch() to call external APIs — weather data (adjust bids for AC companies when temperature exceeds 40°C), stock levels (pause ads for out-of-stock products), or CRM data (adjust bids based on lead quality feedback). Indian ecommerce advertisers use this to sync with inventory management systems.
Common Pitfalls and Best Practices
- Always preview first: Never deploy a script directly to production. A single misplaced decimal can multiply all bids by 10.
- Respect API quotas: Scripts have execution time limits (30 minutes) and API call limits. Batch operations and use selectors efficiently.
- Version control: Keep script copies in Google Docs or a Git repository. The in-platform editor has no version history.
- Error handling: Use try-catch blocks and email notifications for errors. A silently failing script is worse than no script.
- Document your scripts: Add comments explaining the business logic, thresholds, and assumptions. When a team member inherits your scripts, they need to understand the intent.
Cost and Time Savings for Indian Agencies
A typical Indian PPC agency managing 15 clients can save 15–25 hours per week by automating budget pacing, quality score tracking, search term analysis, and performance reporting through Ads Scripts. At an average analyst salary of ₹4–6 LPA, this translates to approximately ₹3–5 lakhs in annual savings per analyst, or the ability to manage more accounts without hiring additional staff.

Frequently Asked Questions
Do I need to know JavaScript to use Google Ads Scripts?
Basic JavaScript knowledge helps, but you can start with pre-built scripts from Google’s script library, community repositories, and resources like BrainLabs and FreeAdWordsScripts.com. Customising existing scripts is much easier than writing from scratch.
Can scripts replace Google Ads automated bidding strategies?
No. Google’s machine learning bidding strategies (Target CPA, Target ROAS, Maximise Conversions) process real-time signals (device, location, time, audience, query context) that scripts cannot access. Scripts are best for account management automation, monitoring, and reporting — not real-time bid optimisation.
Are Google Ads Scripts free?
Yes. Scripts are a free feature available to all Google Ads accounts. There is no additional cost beyond your regular ad spend and any third-party tools you integrate with.
How many scripts can I run per account?
Each Google Ads account can have up to 250 scripts. MCC accounts can have up to 250 MCC-level scripts. Each script has a 30-minute execution time limit per run.
Can scripts work with Performance Max campaigns?
Ads Scripts have limited access to Performance Max campaigns. You can read basic performance data and adjust budgets, but you cannot access or modify individual assets, audience signals, or listing groups within PMax campaigns. Google is gradually expanding script access to PMax.
