Are you wondering how to automate the management of your Google Ads campaigns to save time? Google Ads scripts are snippets of code that work in the background to automate repetitive tasks like detecting URL errors, spotting negative keyword conflicts, or alerting you when an account is not receiving impressions. For an e-commerce merchant, these scripts free up valuable time to focus on strategy and critical optimizations.
However, setting them up requires a minimum of technical knowledge and a good understanding of the parameters to customize. Without this, you risk receiving unnecessary alerts or missing out on key information. So, how do you automate the management of your Google Ads campaigns with scripts? On the agenda:
What is a Google Ads script and why use it?
How to configure change history alerts?
How to extract Performance Max search terms?
How to analyze Performance Max insights in detail?
How to check for the presence of responsive ads?
Let's go.
Summary
What is a Google Ads script and why use it?
A Google Ads script is a small program written in JavaScript that runs automatically in your Google Ads account. It can perform actions such as checking URLs, analyzing reports, sending emails, or modifying bids. The main benefit is to reduce the time spent on repetitive tasks and to react faster to anomalies.
For an e-commerce business, this means less time manually monitoring each campaign and more time to focus on strategy. For example, a script can detect that a product is no longer getting impressions and alert you immediately, which prevents lost sales.
Scripts are customizable: you can adjust thresholds, alert recipients, and execution frequency. They are accessible via the Google Ads interface, under the "Scripts" tab.

How do I set up change history alerts?
The "Change History Alerts" script monitors changes made to your Google Ads account. It is useful when multiple users have access to the account, as it helps track who changed what and when. For example, if a colleague pauses an important keyword, you are immediately alerted.
To set it up, you need to create a Google Sheet and paste its URL in the SPREADSHEET_URL parameter. Next, fill in the email addresses of the recipients in EMAIL_ADDRESSES. You can also ignore certain users by adding their emails in IGNORE_USERS.
The script sends a daily email with the details of the changes. You can customize the subject and body of the message, as well as the analyzed period (defaulting to "yesterday"). This automation is ideal for keeping an eye on your team's actions without having to check the history manually.
How to extract Performance Max search terms?
The "Performance Max Search Terms and Categories" script retrieves the queries that triggered your ads in Performance Max campaigns. For a long time, Google did not share this data, but it is now available in the insights report. This script organizes them into an easy-to-filter Google Sheets spreadsheet.
This allows you to identify queries that convert well and add them as keywords in your search campaigns. Conversely, queries with many clicks but few conversions can be added as negative keywords to avoid wasting your budget.
Customize the minimum impression threshold with MINIMP (default 10) to avoid entities with little activity. The REPORTLASTNDAYS parameter defines the analysis period (30 days by default). If you leave SPREADSHEET_URL blank, the script generates a new sheet each time it runs.
How to analyze Performance Max insights in detail?
The "Performance Max insights" script provides comprehensive data on your Performance Max campaigns. It displays the percentage of spend by channel (Shopping, Video, Display, Search/Other), costs and conversions by campaign and network, as well as performance by asset group.
It is a valuable tool because Performance Max leaves little control over ad placement. For example, if you sell products with a feed, you expect the majority of spend to go to Shopping. If the script shows that the Display share is too high and is not converting, you can re-evaluate your strategy.
To use it, copy the Google Sheets template and paste the URL into the SS parameter. The script analyzes the last 30 days by default, but the paid version allows for longer periods. This transparency is essential for optimizing your campaigns.
How to check for the presence of responsive ads?
The "RSA Checker" script identifies ad groups that do not have active responsive search ads (RSAs). Google now classifies all new ads as responsive, but some groups may still contain expanded text ads or disapproved ads.
This script is particularly useful when transitioning to RSAs or for new accounts. It also checks if an ad has been disapproved by Google, which may explain the absence of an ad. You can configure CHECKPAUSEDCAMPAIGNS, CHECKPAUSEDADGROUPS, and CHECKPAUSEDADS to include paused items.
The ALERTONNEWENTITIESONLY parameter allows you to receive alerts only for new ad groups without RSAs. Add recipients in RECIPIENTEMAILS and define a label (default is "no_rsa_present") to mark the affected groups. Run this script weekly to stay up to date.
What are the concrete benefits of scripts for an e-merchant?
Google Ads scripts offer several practical benefits for an online merchant. First, they reduce daily management time: instead of manually checking each campaign, you receive automatic alerts in case of a problem. Second, they improve responsiveness: a drop in impressions or a URL error is detected immediately, which limits budget waste.
They also allow for better transparency, especially for Performance Max campaigns where data is often opaque. Finally, they help maintain a high account quality by regularly checking for the presence of responsive ads and avoiding negative keyword conflicts.
For an e-merchant, this translates into more time for strategy, bid optimization, and improving the customer experience. Scripts are therefore a profitable investment in the long term.
How to integrate scripts into your daily routine?
To get the most out of scripts, integrate them into a daily or weekly routine. For example, run "Change History Alerts" every morning to check the previous day's changes. The "Performance Max Insights" script can be launched once a week to analyze spending trends.
The "RSA Checker" is useful every week to ensure that all ads are active. As for the search terms script, it can be run after each data collection period, for example every 15 days, to adjust your keywords.
The important thing is not to overload your inbox with unnecessary alerts. Customize thresholds and recipients to receive only relevant information. This way, you keep a clear view without being overwhelmed.
What are the limitations of Google Ads scripts?
Google Ads scripts have a few limitations to keep in mind. First, they require basic technical skills to customize. If you are not comfortable with coding, you may need to hire a developer or use ready-made templates.
Second, they do not replace human analysis. A script can detect an anomaly, but it is up to you to decide on the best action. For example, if a script reports a drop in impressions, you need to understand why and adjust your strategy accordingly.
Finally, scripts are limited by the data available in Google Ads. Some information, such as advanced conversion data, may require additional configuration. Despite these limitations, scripts remain a powerful tool for automating repetitive tasks.
How to avoid common mistakes when using scripts?
A common mistake is setting thresholds too low, which generates unnecessary alerts. For example, with MINIMP at 10, you will receive notifications for terms with very few impressions, which can be noisy. Adapt the threshold to the size of your account.
Another mistake is forgetting to update the email addresses of the recipients. If a colleague leaves the team, they will continue to receive alerts, which can pose privacy issues. Regularly check the settings.
Finally, do not neglect the execution frequency. A script that runs too often can overload your account and slow down performance. Follow the frequency recommendations for each script and adjust as needed.
How do scripts integrate with other automation tools?
Google Ads scripts can be combined with other automation tools for even more effective management. For example, you can use scripts to export data to Google Sheets, then analyze it with visualization tools like Google Data Studio.
They can also be triggered by external events via the Google Ads API, allowing for advanced automation. For example, a script can be launched when a product is out of stock, to pause the corresponding ads.
For an e-commerce retailer, this integration is valuable because it allows synchronization of advertising campaigns with inventory and sales data. This reduces the risk of wasted budget and improves the relevance of ads.
