Do you spend half of your day monitoring, updating, and tweaking your Google Ads?

If you do, that’s not sustainable—or the best use of your brain.

And the automated rules you set up don't cut it because they can't handle the frequency or level of detail you need to manage.

What you need is Google Ads Scripts

Oh yeah, this is the big leagues. And you can absolutely be a part of this big league. 

Starting from the top, we'll explain 

  • What Google Ads scripts are
  • How they work
  • How to set them up

By the end of this post, you’ll feel like a Google Ad Script pro...with a lot more free time on your hands.

What are Google Ads scripts?

Google Ads scripts are snippets of JavaScript code that give you better control of your campaigns. They automate internal functions within your Google Ads account and also interact with external data.

Why use Google Ads scripts?

Direct benefit: Google Ads scripts save time

Automate the more tedious processes in PPC account maintenance, then focus more on optimizing actual performance.

Scripts often catch minor issues or opportunities missed by us humble humans.

There’s a lot of data to comb through in any PPC campaign, so it’s understandable if you miss a low-performing keyword or don’t recognize where you should build a new ad group.

That's why you use an automation tool. As a whole, they're meant to help optimize your Google Ads optimization routine itself.

How to set up Google Ads scripts

Scripts are intimidating if you don’t have a coding background. There are 7 parts:

  1. Functions
  2. Variables
  3. Objects
  4. Entities
  5. Selectors
  6. Methods
  7. Iterators

The good news is, according to Google, you only need entry-level familiarity with JavaScript—the IDE helps with syntax highlighting, auto-complete, and previewing.

Plenty of pre-built scripts are available to the public if you want to use the plug-and-chug method. But, in our experience, a little customization goes a long way, even with these pre-built scripts.

Let's take a look at script elements.

Setting scripts up in Google

  1. Sign in to your Google Ads account.
  2. Click Tools > Bulk actions > Scripts
