Google Ads script: a daily email when search terms waste money

What the script does

Once a day it reads your search terms report, keeps the terms that spent money and brought no conversions, and emails you the list, highest spend first, with the campaign, the cost and the clicks of each one. If nothing crosses the threshold, it sends nothing.

It runs inside your own Google Ads account with your own permissions: once it is pasted, no outside server sees your data, ours included.

How to install it in five minutes

1. In Google Ads, open Tools, then Bulk actions, then Scripts, and press the plus button to create a new script.
2. Delete the example code and paste the script Ads MCP gave you. It already has your email and threshold in the first lines.
3. Press Authorize, then Preview: the log shows what the script found.
4. Save, go back to the list of scripts and set the frequency to Daily.

Google explains scripts and their permissions in its own guide (Google Ads Help).

Getting the script

Connect Ads MCP to your AI assistant (two minutes) and ask: "set up the daily watchdog script for my account". The tool watchdog_script returns the script with your email, the days to look back and the minimum spend already filled in. It is part of the paid plans.

Settings you can change

• EMAIL: where the alert goes. For more than one address, separate them with commas.
• DAYS: how many full days back it looks, up to yesterday. 7 is a good start; use 14 or 30 for small accounts.
• MIN_SPEND: the smallest spend, in your account currency, that makes a term worth an email.

What to do with the email

For each term, ask one question: do you sell that? If not, add it as a negative keyword. If yes, keep it and give it time.

If you manage many accounts, or want the negative keywords file built for you, Ads MCP does the same review from ChatGPT, Claude or another AI assistant and returns a file ready for Google Ads Editor. It is read-only too.
