Last month, I sent out a newsletter asking you:\u00a0“What AI + PPC question is on your mind right now?”<\/a><\/em><\/p>\n\n\n\n

Many of the responses I got were in line with:\u00a0<\/p>\n\n\n\n

“Do you still use scripts now that AI Agents have entered your agency?”<\/em><\/p>\n<\/blockquote>\n\n\n\n

Yes. I still use (Google Ads) scripts. A lot.<\/p>\n\n\n\n

My two main applications of scripts are:<\/p>\n\n\n\n

First, Google Ads Scripts for monitoring and alerting.<\/strong><\/p>\n\n\n\n

Scripts are great for simple, repetitive tasks that do not require a lot of complex reasoning. Scripts are also great for automating rule-based logic based on numbers. They are also extremely reliable. They run, they do their thing, exactly the same thing and the same way every time.<\/p>\n\n\n\n

Agents that use LLMs are much less reliable. LLMs are Large Language Models, not Large Number Models -> better with text than numbers. LLMs also tend to hallucinate and respond differently every time you ask them the same question. Therefore, agents make mistakes, just like us humans.<\/p>\n\n\n\n

So, just like I use Google Ads scripts to monitor the changes made by humans, I use Google Ads scripts to monitor the changes made by agents. And I have them send me alerts when things go wrong.<\/p>\n\n\n\n

Here are just a few of the many examples of the things I still like to automate via Google Ads Scripts (with no AI involved):<\/p>\n\n\n\n

    \n
  1. Monitor account uptime, and send an alert if, for whatever reason, an account is down: https:\/\/nilsrooijmans.gumroad.com\/l\/account-down-alerts<\/a><\/li>\n\n\n\n
  2. Monitor change history, and send an alert if someone, or something, outside of my team made a change in the account: https:\/\/nilsrooijmans.gumroad.com\/l\/change-history-alerts<\/a><\/li>\n\n\n\n
  3. Conversion drop alert, sends an alert if a significant drop in tracked conversions occurs: https:\/\/nilsrooijmans.com\/daily\/google-ads-script-conversion-drop-alerts-and-a-big-thank-you<\/a><\/li>\n<\/ol>\n\n\n\n

    My second application of scripts is: software code as part of the agent skills.<\/strong><\/p>\n\n\n\n

    These days, agents often have so-called “skills” \u00a0to perform tasks. These skills consist of Markdown files (skill.MD) with natural-language instructions telling the agent how to approach a task. Example: “When adding new headlines, always spellcheck them before adding and make sure they respect the character limit.”<\/p>\n\n\n\n

    Skills can also have scripts. These are pieces of deterministic code that the agent can use to perform the task reliably. Example: “takes a list, returns per-headline pass\/fail with reasons (over 30 chars, duplicate of headline #3, excessive punctuation, banned symbol, etc.). Pure deterministic check, no LLM needed.”<\/p>\n\n\n\n

    Without scripts, the agent skill would have to reinvent the deterministic parts on every run \u2014 e.g., re-deriving character-count checks, dedup logic, and API call structure from scratch in the model’s head. This is slower, more expensive, and far less reliable than simply executing code that already works.<\/p>\n\n\n\n

    So, yeah, scripts are here to stay.<\/p>\n\n\n\n

    Happy scripting!<\/p>\n\n\n\n
