How to use Google Ads automation
Google Ads automation lets you set rules that automatically take action based on how your campaigns are performing. So instead of checking and adjusting bids all day, the system can do it for you when certain conditions are met.
There are three common ways to do this: using Google’s built-in rules, writing custom scripts, or relying on Google Ads automation software to handle more complex campaign management.
- Google’s built-in rules: Google’s built-in rules can be set up directly in the Google Ads interface. They’re a good fit for basic needs, but don’t offer much flexibility. If you’re running bigger or more complex campaigns, you might find them a bit limited.
- Automating using JavaScript: Custom scripts are snippets of JavaScript code that can control campaigns on your behalf. They make changes directly inside your Google Ads account, and there are no limits to how complex they can be. The only problem is that you need to know JavaScript fairly well to write them.
- Google Ads automation tools: There are third-party tools built specifically to automate Google Ads campaigns. These platforms connect to your account through APIs and offer more flexibility than Google’s built-in options or custom scripts. For example, Bïrch lets you create smart rules through a visual interface, without code, and supports features like sending alerts to Slack.
Using Google’s built-in automation features
Google Ads includes several built-in automation features that can take over different parts of campaign management. Some are fully automated: you choose a goal like leads or sales, and Google handles bids, placements, and targeting. Other built-in features let you keep more control but still use automation to help with tasks like bidding or ad creation.
These features can help you save time, especially if you’re managing multiple campaigns. But the downside is that you won’t always know why it makes certain decisions, and it can be harder to do custom adjustments.
Let’s look at some of the tools you’ll come across on the platform.
Smart Campaigns
Smart Campaigns are built for simplicity. You enter your business info, write a few lines of ad copy, and set a budget. Google takes care of targeting, bidding, and placements. They’re quick to launch and easy to manage, but you won’t get much visibility or control. Keyword targeting, audience selection, and reporting are limited, and most decisions happen behind the scenes.
Performance Max
Performance Max runs one campaign across all of Google’s channels, including Search, Display, YouTube, Gmail, and Discover. You upload headlines, images, videos, and audience signals, and Google automatically combines and delivers them. You don’t control where your ads show or which assets are used. The system is focused on driving conversions, but reporting is limited and it’s hard to know what’s working.
Smart Bidding
Smart Bidding adjusts your bids automatically based on the goal you set. You can optimize for conversions, keep your cost per lead within a target, or focus on return on ad spend. Google sets bids in real time using signals like device, location, and search behavior. It’s meant to improve results with less manual input, but it’s not always clear why certain bids happen or how to steer them.
Responsive Search Ads (RSAs)
Responsive Search Ads let you enter multiple headlines and descriptions, and Google automatically tests different combinations to see what performs best. Over time, the system shows the versions it predicts will get more clicks or conversions. You don’t control which combinations are shown, and performance data for each asset is limited.
Automated Rules
This feature lets you set specific criteria to automatically adjust bids, budgets, statuses, and more. For example, you can create a rule to pause low-performing ads or increase bids during peak hours.
💡 Google’s automations can be useful, and most of them can be adjusted or turned off. But if you rely only on what the platform suggests, you’ll eventually run into limits. Google’s goal is to spend your budget, not manage it to your liking. And when things get more complex (like comparing campaigns or making bulk edits) doing it all inside Google Ads can get time-consuming fast.
Automating using JavaScript
If you’re comfortable with code, Google Ads scripts let you automate tasks using JavaScript. These scripts can adjust bids, pause keywords, pull reports, or make changes based on custom logic. You write and manage them directly inside your Google Ads account.
To get started, go to Tools → Bulk Actions → Scripts → +. From there, you can write your own or use templates from trusted sources. Google offers a few, and there are also libraries online with ready-to-use scripts for common tasks like budget pacing or broken URL checks.
This option gives you more flexibility than built-in rules and can handle complex logic that would be hard to recreate through point-and-click tools. You can also schedule scripts to run at specific times or intervals.
The downside? You need to know JavaScript well enough to write, test, and maintain your code. If something breaks, you’ll have to debug it yourself. There’s also no visual interface, so it’s less accessible for teams that aren’t technical.
Using Google Ads automation software
Choosing the right Google Ads automation tool depends on your budget, ad channels, and the level of automation you need. Below is a side-by-side comparison of key features across Bïrch, Optmyzr, and Adalysis, including pricing, supported platforms, and core capabilities.
Bïrch stands out by supporting multiple ad platforms, including Meta, Google, TikTok, and Snapchat. It offers competitive pricing and includes built-in integrations with Slack and Google Analytics for streamlined reporting and alerts. Its automation tools simplify tasks like post boosting, rule creation, and creative tracking across channels.
3 best Google Ads automation rules
Automation works best when it's tied to clear, simple rules that reflect how you already think about your campaigns. These examples cover common tasks that can be automated to save time, protect your budget, and improve performance using Bïrch.
Pause underperforming keywords
Instead of letting expensive, low-performing keywords keep running, you can set a rule to pause them. For example, set a rule in Bïrch to pause any keyword with over 100 conversions in the past week if the cost per conversion goes above $20. It’s a simple way to cut waste and keep your budget focused.
Automate bid management
Automating bids helps you stay competitive without adjusting them all day. On Bïrch, you can schedule changes around peak hours, like raising bids in the evening when performance is better, then lowering them later to control ad spend. This keeps your bids aligned with real activity while staying within budget.
Increase and decrease campaign budget
Budget rules help you spend more on what’s working and cut back where results are weak. Using Bïrch, you can raise the budget on campaigns with steady conversions and low costs, or lower it when spend is high but returns are poor. These rules can run on a set schedule, so changes stay consistent and controlled.
Make Google Ads automation work for you
Google Ads automation helps you manage campaigns faster, scale smarter, and stay in control without doing everything yourself. Whether you’re running a single account or juggling multiple, automation gives you more time to focus on strategy instead of day-to-day maintenance.
With tools like Bïrch, you can set up custom rules, monitor performance, and adjust spend without writing a line of code.
