Free Negative Keyword Generator
for Google Ads

Negative keywords are words and phrases you add to your Google Ads campaign to stop your ads from showing for searches that are not relevant to your business. For example, if you sell a paid digital marketing course, adding "free" as a negative keyword stops your ad from showing when someone searches "free digital marketing course". This prevents wasted ad spend on clicks that will never convert.

You enter your product, service or campaign topic and the tool analyses the keyword against a library of common negative patterns grouped by intent. It detects your industry from the keyword and loads the most relevant negative categories: job seekers, researchers, free-only searchers, students, DIY seekers and more. Each keyword comes with a recommended match type and the reason it was flagged. The output is ready to copy or download as a Google Ads Editor CSV.

A broad match negative blocks any search containing that word anywhere. A phrase match negative blocks searches containing that exact sequence of words. An exact match negative blocks only that specific search. For most negative keywords, phrase match gives the right balance. Use broad for short, safe exclusions like "free" or "jobs". Use exact when you want to block one specific query without over-filtering.

There is no fixed number, but 30 to 60 negative keywords is a practical starting point for most campaigns. The right number depends on your industry and how broad your seed keyword is. Prioritise job seeker terms, informational terms and free-only terms first, since these account for the majority of irrelevant clicks in most B2C and B2B campaigns. Add more as you review your Search Terms report after the first two weeks of running.

Start at campaign level. Campaign-level negatives apply to every ad group in that campaign, which gives you full coverage with less maintenance. Move to ad group level only when you have a specific ad group whose targeting you want to protect without affecting others. For most small and mid-sized accounts, campaign-level negatives are sufficient.

Over-adding negatives can restrict your reach more than intended and reduce the number of auctions your ad enters. This is most common with broad match negatives applied to short words. If your impressions drop sharply after adding negatives, check your Search Terms report for valuable queries that are now being blocked. Remove or change the match type for any negative that is blocking relevant traffic.

Yes, but with differences. Shopping campaigns do not use keyword targeting, so negative keywords work differently. You still add them the same way, but since you are not bidding on specific keywords, you rely entirely on negatives to filter irrelevant searches. Phrase and exact match negatives are more useful in Shopping campaigns than broad match negatives, which can block too many product queries.

Review your Google Ads Search Terms report every two weeks for the first three months of a new campaign. Add new irrelevant terms you find there. After that, a monthly check is enough for established campaigns. Your negative list is never final — new search patterns emerge constantly, especially around seasonal events, trending topics and changes in how people search for your category.

For anyone advertising a digital marketing product or service, the highest-priority negatives are: job-related terms ("digital marketing jobs", "digital marketing salary", "digital marketing internship"), informational terms ("what is digital marketing", "digital marketing meaning"), free-seeking terms ("free digital marketing course", "digital marketing pdf") and student research terms ("digital marketing notes", "digital marketing ppt", "digital marketing assignment"). These four categories account for the majority of irrelevant spend in this niche.

Yes, completely free. No account, no credit card, no hidden cost. The tool allows a set number of uses per day to keep it running for everyone. If you need to generate lists for more campaigns in a day, use the daily limit for your highest-priority campaigns first.
