I’ve addressed<\/a> the benefits of Google Ads scripts to automate aspects of account management. Producing custom scripts is now much easier with generative AI platforms.<\/p>\n

Scripts can go beyond automation to solve problems. For example, it’s not always evident when an account stops serving ads. The payment method may fail, or Google could reject them. The “Account Down<\/a>” script runs hourly and sends an email when an account hasn’t seen an impression in a designated period.<\/p>\n

I’ve struggled with campaigns that set a higher target cost per acquisition than the budget. It’s not always obvious. A budget might be $500, but the tCPA is $600. The budget should be at least three times the tCPA in my experience.<\/p>\n

AI for Ad Scripts<\/h3>\n

Here’s where AI comes in. Tools such as ChatGPT, Gemini, and Claude (my favorite) can generate scripts quickly.<\/p>\n

\"Sample<\/a>

Generative AI platforms such as Claude can produce scripts quickly.<\/p><\/div>\n

Here’s my prompt in Claude to create a script:<\/p>\n

Please write a Google Ads script that reviews all campaigns and sends an email alert when the tCPA is higher than the campaign budget.<\/em><\/p>\n

Here’s Claude’s response:<\/p>\n

Google Ads tCPA Alert Script<\/em><\/p>\n

This script:<\/em><\/p>\n

1. Iterates through all enabled campaigns in your Google Ads account<\/em>
\n2. Identifies campaigns using Target CPA bidding strategy<\/em>
\n3. Compares each campaign’s tCPA value against its daily budget<\/em>
\n4. Creates a list of campaigns where tCPA exceeds the budget<\/em>
\n5. Sends you an email alert with details if any campaigns meet this condition<\/em><\/p>\n

I pasted the script into Google Ads and received an error.<\/p>\n

3\/5\/2025 3:47:20 PM TypeError: campaign.bidding(...).get is not a function\r\nat main (Code:39:40)\r\nat Object.<anonymous> (adsapp_compiled:20555:54)<\/pre>\n
I then prompted Claude to fix the error. Here’s Claude’s response:<\/p>\n
Google Ads tCPA Alert Script – Fixed<\/em><\/p>\n
I’ve fixed the error by correcting how the script retrieves the target CPA value. The issue was with the line `var bidding = campaign.bidding().get();` which was using an incorrect method call.<\/em><\/p>\n
Key changes made:<\/em><\/p>\n
1. Replaced the problematic method chain with a direct call to `campaign.bidding().getTargetCpa()`<\/em><\/p>\n
2. Added error handling with try\/catch blocks to gracefully handle different API versions and bidding strategy configurations<\/em><\/p>\n
3. Added support for retrieving tCPA from shared bidding strategies (which have a different access method)<\/em><\/p>\n
4. Added validation to ensure tCPA was successfully retrieved before comparing it to the budget<\/em><\/p>\n
The script \u2014 download it here<\/a> \u2014 now runs in Google. I solved a problem through a series of prompts.<\/p>\n
Not perfect<\/h3>\n
My next AI task was to obtain a script that identified all active ad groups in live campaigns with no impressions in 21 days. The alert would trigger me to investigate the cause.<\/p>\n
Claude’s script worked, but it had two errors:<\/p>\n
