What Is the Negative Keyword Generator & Why Is It Essential?
Filter out unwanted search terms, stop wasting ad spend on irrelevant clicks, and export clean negative lists for Google Ads.
Every time someone clicks your Google Ad on an irrelevant search term, your budget takes a hit. If you sell paid commercial services or products, you do not want to pay for clicks from people searching for DIY guides, student projects, customer support phone numbers, or job openings. Adding negative keywords stops your ads from showing on these wasteful searches.
This tool provides pre-built negative keyword lists across 16 common waste categories and lets you paste your own custom search terms. Everything runs directly in your browser, so your campaign data stays on your machine while you format and export clean negative lists in seconds.

Google Ads Negative Match Type Behavior Matrix (Cheat Sheet)
Understanding how each negative match type functions prevents blocking qualified buyers while eliminating non-converting traffic:
| Negative Match Type | Google Ads Syntax | What It Blocks | What It Does NOT Block | Best Practice Use Case |
|---|---|---|---|---|
| Negative Broad Match | running shoes |
Blocks queries containing all terms regardless of word order (e.g. blue running shoes, shoes for running). | Does NOT block queries missing any single term (e.g. blue shoes, running gear). | Account-wide exclusion of broad irrelevant service categories. |
| Negative Phrase Match | "running shoes" |
Blocks queries containing the exact phrase in identical sequence (e.g. buy running shoes, cheap running shoes). | Does NOT block queries with extra words inserted between terms (e.g. running red shoes). | Filtering multi-word commercial confusion (e.g. "zero cost", "customer support"). |
| Negative Exact Match | [running shoes] |
Blocks queries matching the exact term only with zero additional words (e.g. running shoes). | Does NOT block queries with even one extra search term (e.g. running shoes sale, best running shoes). | Preserving high-intent long-tail traffic while isolating single ambiguous queries. |
Frequently Asked Questions (FAQs)
A campaign-level negative list applies strictly to a single Google Ads campaign. A shared negative keyword list is created in your account Shared Library and can be linked to multiple search campaigns simultaneously, ensuring account-wide protection against unwanted search queries with a single update.
No. Unlike positive keyword targeting, Google Ads negative keywords do not automatically match close variants, plurals, or misspelled terms. If you exclude 'shoe' as a negative, your ad may still trigger on 'shoes' unless both variants are explicitly added to your negative list.
Google Ads allows up to 5,000 negative keywords per campaign-level list, up to 10,000 negative keywords per shared list, and up to 20 shared lists per account. Utilizing curated silos ensures you block common waste terms without exceeding account boundaries.
Use negative exact match [term] when a single standalone query produces zero conversions, but longer searches containing that term represent qualified commercial intent. For example, [crm] alone might be too broad and costly, but 'enterprise crm software' represents a qualified buyer.
