Generate customized reports and deliver them via email on a schedule (e.g., daily, weekly).
For example, email a performance summary every morning, detailing impressions, CTR, and conversions.
Multi-account management
Use manager account (MCC) scripts to simultaneously adjust bids, budgets, or other settings across multiple accounts.
For example, adjust bids for all accounts during specific peak hours.
Data integration with external sources
Enhance campaigns by integrating data from Google Sheets, Google Analytics, or external APIs.
For example, dynamically adjust campaigns based on competitor pricing or inventory levels.
These examples demonstrate the versatility of Google Ads scripts in addressing common challenges while driving efficiency and precision in campaign management.
How Google Ads scripts work
Setup and execution
Scripts are managed within the Google Ads interface under Tools & Settings > Scripts.
The scripts interface is where you add, edit, and schedule scripts for your ad account or MCC account.
Advertisers can write, test, and schedule scripts directly from this dashboard.
Write the script using the Google Ads Script editor or copy-and-paste a script you found on a trustworthy site.
Preview changes before live deployment to avoid making unexpected changes to your account.
Save the script for manual use when needed or schedule it to run at desired intervals. Scripts can be run as often as once per hour.
When previewing a script to confirm it works as intended, pay close attention to two important sections:
The logs show details about all the steps a script goes through but it may be blank unless the script uses the Logger.log() function to write output to this section.
Changes will show if any parts of your account would change if the script were run in normal mode (not preview mode).
Logs and Changes help you confirm the script is working properly.
