Definition
Negative keywords tell Google not to show your ads for specific search queries. Adding them prevents your budget from being spent on searches that contain those terms, regardless of your regular keyword targeting. They are the cheapest and fastest way to protect your budget from traffic that isn’t going to convert either way.
Negative Keyword Match Types
Negative keywords use their own match type logic, working differently from regular match types.
[table]
Match Type | Syntax | What It Blocks
Negative Broad | keyword | Blocks queries containing all the words in any order
Negative Phrase | "keyword" | Blocks queries containing the exact phrase in order
Negative Exact | [keyword] | Blocks only queries that match exactly
[/table]
Negative broad match is different from positive broad match. It only blocks the specific terms you add, not synonyms or related words.
For example, adding “free” as a negative broad match blocks searches containing “free”. It won’t block searches like “no cost” or “gratis.” You need to add those terms separately.

Why Negative Keywords Matter More Than People Think
Demo volume is a vanity metric if the wrong people are showing up.
An account that generates 100 demos per month sounds impressive until you learn 70 of them are job seekers, students, or people looking for free versions of your product.
Those 70 demos cost real money to produce zero pipeline.
Negative keywords are the cheapest lever for fixing lead quality. Cheaper than better ad copy, landing pages, and tighter targeting. A well-built negative list stops the bleeding before it starts.
This is the reason negative keyword lists should be the first-week deliverable for any B2B SaaS Google Ads account. Not the third-month optimization. Skipping it is one of the Google Ads mistakes costing B2B SaaS accounts six figures.
How to Build Your Own Negative Keyword List
Beyond the starter list, every account needs custom negatives based on its specific vertical. Try the following process.
Review search terms weekly. Look at what queries triggered your ads. Anything obviously junk gets added as a negative. Explore our guide on PPC keyword ideas.
Add negatives at the right level. Account-level for universal junk (jobs, free, tutorial). Campaign-level for competitor names in non-competitor campaigns. Ad group-level for tightly scoped exclusions.
Cross-check between campaigns. Add negatives for your brand terms in non-brand campaigns. Add competitor names as negatives in your brand campaign. This prevents traffic from bleeding across campaigns.
Update monthly. Search behavior changes. New junk terms appear. Established terms stop being relevant. Treat negatives as a living list, not a one-time setup.
Our complete Google Ads optimization checklist covers negatives as one of the core weekly tasks.
And the guide on PPC keyword research covers how you can identify negative themes during keyword research.

- Move to a monthly cadence after the account stabilizes.
