To find negative keywords for Google Ads with AI, ask an AI assistant connected to the Madgicx Google Ads MCP to read your search terms, pick out the ones that spent money without converting, and turn them into a list of negative keyword candidates. You review the list and add the negatives in Google Ads yourself.
TL;DR
- Negative keywords come from the searches that already cost you money, so the search terms report is the starting point.
- The assistant reads each search term with its campaign, clicks, cost and conversions.
- It flags terms that spent without converting and words that repeat across them.
- You get a list of candidates grouped by campaign, with the risky ones marked.
- The connection is read only: you add the negatives in Google Ads.
Who this is for
- Search advertisers who know their accounts leak budget on loose matches but never get through the whole report.
- Agencies taking over a Google Ads account and wanting a quick cleanup list.
- Founders running their own campaigns who are not sure what to exclude.
Analyze Google Ads with your AI assistant
Search terms, keywords and schedules in plain words. Read only. Included in the 7-day free trial.
Try for Free ($0 Trial)The prompt to paste
Read the search terms for my Google Ads account [account name] for the last 60 days. Find search terms with cost over [amount] and no conversions. Group them by campaign. Then list the single words that repeat across those terms, such as "free", "jobs", "how to" or competitor names. Prepare a negative keyword list for each campaign and mark any term that could be a real customer search, so I can double-check it before excluding it.
Follow-ups that work well:
Which of those terms are too close to my converting searches to exclude safely?
How much did the terms on this list cost in total over the period?
The prompt works in any AI assistant connected to the Madgicx Google Ads MCP. To set it up, connect your AI assistant and add the Google Ads server address shown there.
What the MCP reads
- Your Google Ads accounts. The accounts you can reach, with currency and time zone.
- Search terms. Each term with its campaign, clicks, cost and conversions for the dates you choose.
- More columns on request. The assistant uses a custom Google Ads query, so you can narrow it to one campaign or ask for extra metrics.
What the answer looks like
A table per campaign with the candidate negatives, their cost and conversions, and a short note on why each was flagged. Below it, a list of repeated words with how many terms contain them. Terms that look like genuine customer searches sit in their own "check first" group, because an exclusion that is too broad can block sales.
What to do next
- Start from the full report if you have not read it yet: read the search terms report.
- Check the keywords that triggered those searches: check keyword performance.
- Review the account again after the negatives are in: make a Google Ads report.
It only reads your account
The Madgicx Google Ads MCP is read only. It analyzes your account and changes nothing: no negative keywords, keywords, bids or budgets are added or edited. You add the negatives in Google Ads, at campaign or account level, using the list the assistant prepared.
Try it on your own account
The Google Ads MCP comes with a Madgicx subscription, alongside the Meta ads server, and the 7-day free trial includes both. If you advertise on Meta too, the same assistant can read your Meta ad account in the same conversation.
FAQ
What is a negative keyword in Google Ads?
It is a word or phrase that tells Google not to show your ad for searches containing it. It cuts spend on searches that will not turn into customers.
How do I know a search term is safe to exclude?
Look at cost, conversions and intent. A term with real spend, no conversions and a clearly different meaning is a good candidate. A term that could be a buyer in a different wording deserves a second look.
Can the assistant add the negatives for me?
No. The Google Ads MCP is read only, so it prepares the list and you add the negatives yourself.
How much history should I read?
Sixty to ninety days usually gives enough searches to judge. Shorter periods can miss terms that convert slowly.
