"Scripts" sounds like a developer word. It scares off every founder who doesn't code — which is most of them. Here's what nobody tells you: you don't write Google Ads Scripts. You copy them. Google and the wider ad community have published hundreds of ready-made scripts that paste straight into your account and run on a schedule. The skill isn't JavaScript. It's knowing which three to install and where to get them safely.
What a Google Ads Script actually does
A script is a small automation that logs into your account on a schedule — hourly, daily, weekly — checks something, and either acts or emails you.
Real examples:
- Pause any ad pointing at a landing page that returns a 404
- Email you the moment daily spend jumps 40% above normal
- Pull yesterday's search terms and flag the ones burning budget with zero conversions
- Label keywords that haven't had an impression in 30 days
It runs while you sleep. You check Ads Manager once a week instead of every morning.
Where to get scripts without getting burned
Two safe sources, full stop:
- Google's official scripts library (developers.google.com/google-ads/scripts) — written and maintained by Google
- Named industry sources — Optmyzr, Brainlabs, well-known PPC bloggers who put their name on it
That's it. A script copied from an anonymous forum post or a YouTube comment is a real risk. More on that below.
The 3 scripts every founder should install first
1. The link checker (404 monitor)
This script crawls every final URL in your account and emails you if one is broken. A dead landing page means you're paying for clicks that land on an error. For a Thai SMB spending ฿1,000/day, one broken URL over a weekend is ฿2,000 gone. Run it daily.
2. The spend / anomaly alert
It compares today's numbers against your recent average and emails you when something swings hard — spend up 40%, CPC doubled, conversions dropped to zero. You find out in an hour, not when you open the account three days later.
3. The search-term cleaner
For accounts running Broad or Phrase match, this pulls the search-term report and surfaces queries that spent money with no conversions. You still approve the negatives — the script just hands you the list. It turns a 30-minute weekly chore into a 2-minute review.
The trap nobody talks about
A script runs with your full account permissions. It can pause campaigns, rewrite bids, and spend money — exactly like you can. A malicious or just sloppy script from a random source can do real damage before you notice.
When NOT to use a script
Google Ads has automated rules built in — no code, no library, just a form. If a rule does the job, use the rule. It's simpler.
| You want to... | Use |
|---|---|
| Pause an ad when cost-per-conversion exceeds ฿300 | Automated rule |
| Raise budget on weekends | Automated rule |
| Check landing pages for 404s | Script |
| Pull data from a Google Sheet or external source | Script |
| Run cross-account anomaly checks | Script |
Rules handle simple "if this number, do that" logic. Scripts are for things rules can't reach: external data, crawling URLs, multi-step logic. Don't script what a rule already covers.
What to do next
Pick one script — the link checker — and install it this week. Tools → Bulk actions → Scripts → +, paste, preview, schedule daily. Once that's running and you trust it, add the spend alert. Two scripts cover the two things that quietly drain a small budget: broken pages and runaway spend.
Automation handles the watching. The strategy — which campaigns to run, what to bid, who to target — still needs a human call. When you build a Google Ads blueprint in AdBlueprint, the campaign structure it gives you is exactly what these scripts then monitor for you. Set the strategy once, let the scripts hold the line.
