Google Ads Scripts: The 5 'Bionic' Tools for 8-Figure Accounts

A human being cannot watch a Google Ads account 24 hours a day. A script can.

Google Ads Scripts are snippets of JavaScript that live in the backend of your account. They run on a schedule (Hourly, Daily, Weekly) to perform tasks that are either too boring or too complex for humans.

You do not need to be a developer to use them. You just need to know how to Copy and Paste.

In this guide, we break down the "Essential Stack"—the 5 scripts we install on every single client account on Day 1.

1. The "Link Checker" (The Insurance Policy)

The Problem: You are spending $1,000/day. Your web developer changes a URL structure or deletes a product page. The page returns a "404 Error". Google Ads doesn't know. It keeps sending traffic. You keep paying. We have seen companies lose $10,000+ this way.

The Script Solution: The Link Checker crawls every single active ad in your account. It follows the URL.

• If it sees a 200 OK status -> It does nothing.
• If it sees a 404 Not Found (or 500 Server Error) -> It Pauses the Ad Group immediately and sends you an email with the subject line "EMERGENCY: BROKEN LINKS."

Verdict: Mandatory. (Google has a simple version of this in their library, but we recommend the "Advanced Link Checker" by Russell Savage).

2. The N-Gram Analyzer (The Insight Generator)

The Problem: You have thousands of search terms. It's hard to spot patterns. You might look at "cheap shoes" and "cheap socks" and "cheap hat" and delete them one by one. But you miss the pattern: the word "Cheap" is the problem.

The Script Solution: An N-Gram script breaks down your search queries into 1-word, 2-word, and 3-word strings. It aggregates the data.

• Output:
  • "Cheap" (1-gram): 5,000 Impressions, $500 Spend, 0 Conversions.
  • "Free" (1-gram): 2,000 Impressions, $100 Spend, 0 Conversions.
  • "Review" (1-gram): 1,000 Impressions, $50 Spend, 10 Conversions.

Verdict: This is the fastest way to build a powerful Negative Keyword list. It reveals the "Root Causes" of wasted spend.

3. The "Zero Impression" Pauser (The Janitor)

The Problem: In large accounts (especially Ecommerce), you build up "Cruft." Thousands of ad groups for products that are out of stock or have low search volume. This "Zombie Data" slows down the Google Ads Editor and makes the account hard to manage.

The Script Solution: The script looks for any Ad, Keyword, or Ad Group that has had 0 Impressions in the last 180 days.

• It labels them "Zero Impressions".
• (Optional) It pauses them.

Verdict: Essential for account hygiene. A clean account is a fast account.

4. The Budget Pacer (The CFO)

The Problem: Google's "Daily Budget" is a suggestion (see our Budget Pacing Guide). It's hard to land exactly on $10,000/month manually.

The Script Solution: This script runs every hour.

1. It checks SpendSoFar + DaysRemaining.
2. It calculates the RequiredDailySpend to hit the target.
3. If you are Overspending, it lowers daily budgets by 5%.
4. If you are Underspending, it raises daily budgets by 5%.

Verdict: This allows you to "set it and forget it." You never have to explain to a client why you overspent by $500 or why you "left money on the table."

5. The Pricing/Inventory Sync (Dynamic Data)

The Problem: You run an ad saying "Price: $99". You change the price on your site to $129. The ad still says $99. Users click, see the price hike, and bounce. You look like a liar.

The Script Solution: This script connects your Google Ads to a Google Sheet (or JSON feed) containing your product data.

• It checks the price in the ad copy vs. the price in the feed.
• If they don't match, it pauses the old ad and creates a new one with the correct price parameters.

Verdict: Critical for fast-moving retail or travel (e.g., flight prices).

How to Install a Script

1. Get the Code: Find a reputable script (Google Developers Library is a good start).
2. Navigate: Tools & Settings → Bulk Actions → Scripts.
3. New Script: Click the + button.
4. Paste: Delete the placeholder code and paste yours.
5. Authorize: Click "Authorize" to give it permission to email you and edit campaigns.
6. Preview: ALWAYS CLICK PREVIEW FIRST. It will simulate the changes without running them. Check the logs. Did it try to pause your best campaign? Fix the logic.
7. Schedule: Set it to run Daily (usually at 6 AM or Hourly for Pacers).

Conclusion

Automation is not about replacing humans. It's about freeing humans to do human things (Strategy, Copywriting, Creative). Let the robots check the links. You write the ads.
