Google Ads Negative Keywords: The Ultimate List + Strategy
Every Google Ads account wastes money on irrelevant clicks. The search terms report tells the story — searches like "free," "jobs," "how to DIY," and dozens of other terms that will never convert but still cost you per click.
Negative keywords fix this. They tell Google which searches to exclude, keeping your budget focused on queries that actually lead to sales. Advertisers who actively manage negative keywords cut wasted spend by 20-40% — that's money you can redirect to converting traffic.
This guide gives you ready-to-use negative keyword lists plus the ongoing strategy to keep your account clean.

How Negative Keywords Work
Negative keywords prevent your ads from showing for specific searches. If you sell premium watches and add "cheap" as a negative keyword, your ad won't show when someone searches "cheap watches."
Negative Match Types
Just like regular keywords, negatives have match types:
Negative Broad Match (default): Blocks searches containing ALL the negative words, in any order.
• Negative: shoe repair
• Blocks: "shoe repair near me," "repair running shoes"
• Doesn't block: "shoe store," "repair services"
Negative Phrase Match: Blocks searches containing the negative phrase in order.
• Negative: "shoe repair"
• Blocks: "shoe repair near me," "best shoe repair"
• Doesn't block: "repair my shoes" (words not in order)
Negative Exact Match: Blocks only the exact search query.
• Negative: [shoe repair]
• Blocks: "shoe repair"
• Doesn't block: "shoe repair near me," "shoe repair cost"
Important difference from positive keywords: Negative keywords do NOT include close variants, synonyms, or misspellings. If you add "shoe" as a negative, it won't block "shoes." You need to add both.

Job-Related
Free/Cheap Seekers (if selling premium)
DIY/Information
Education/Research

Note: Only add "review" and "reviews" as negatives if you don't want review-seekers. For some businesses, "best [product] reviews" is high-intent traffic.

How to Find Negative Keywords
1. Search Terms Report (Most Important)
The search terms report shows exactly which queries triggered your ads. This is your primary source for negative keywords.
How to access:
1. Go to Keywords > Search Terms in Google Ads
2. Sort by cost (highest first)
3. Look for irrelevant queries that are wasting spend
4. Add them as negative keywords directly from the report
Review frequency: Weekly for the first 3 months, bi-weekly after.
2. Google Keyword Planner
When researching keywords, the Keyword Planner shows related terms. Many of these will be irrelevant — add them as negatives proactively before launching.
3. Google Autocomplete
Type your main keywords into Google and look at the autocomplete suggestions. Many suggestions will reveal irrelevant search patterns you should block.
4. Competitor Research
Use tools like SEMrush or SpyFu to see which keywords competitors bid on. The queries they DON'T bid on may indicate negative keywords they've identified.
5. Common Sense Audit
For every keyword you add, ask: "What other meanings could this have?" The word "apple" could trigger searches about the fruit, the company, or the record label. Block the meanings that don't apply to you.

Negative Keyword Strategy
Level 1: Account-Level Shared Lists
Create shared negative keyword lists in Tools > Shared Library > Negative Keyword Lists. Apply these across all campaigns:
• Universal Negatives — jobs, free, DIY, etc.
• Industry Negatives — terms specific to your vertical
• Brand Protection — competitor names you don't want to bid on (optional)
Level 2: Campaign-Level Negatives
Add negatives specific to each campaign's theme. If Campaign A sells "men's shoes" and Campaign B sells "women's shoes," add "women" as a negative in Campaign A and "men" as a negative in Campaign B. This prevents cross-campaign cannibalization.
Level 3: Ad Group-Level Negatives
For fine-grained control within a campaign. If Ad Group 1 targets "running shoes" and Ad Group 2 targets "hiking boots," add "hiking" as a negative in Ad Group 1 and "running" as a negative in Ad Group 2. This ensures the right ad group serves the right search.

The Weekly Negative Keyword Routine
Set a recurring 15-minute task every week:
1. Open Search Terms report — filter by last 7 days
2. Sort by cost — focus on what's spending the most
3. Identify irrelevant terms — anything that won't convert
4. Add as negatives — choose the right match type:
• Single word causing issues → Negative Broad Match
• Specific phrase causing issues → Negative Phrase Match
• One exact query causing issues → Negative
