Negative Keywords Google Ads: Complete Strategy Guide + Starter List 2026

Negative keywords are the words and phrases that prevent your ads from showing for irrelevant searches. Unlike most Google Ads optimizations, adding negatives is purely additive — you only block bad traffic, you never risk losing good traffic. Yet most accounts use a fraction of the negatives they should.

Why Negative Keywords Matter More Than You Think

Review irrelevant search terms using your own account data. Negative keywords can prevent future irrelevant matches, but neither a fixed saving nor a lower CPC is guaranteed. Check that exclusions do not block valuable demand.

The Three Match Types for Negatives

• Negative broad match: Blocks queries containing ALL your negative words in any order. Default type. Use for general irrelevancies
• Negative phrase match: Blocks queries containing your exact phrase. Use when word order matters (e.g., 'price list' but not 'list price')
• Negative exact match: Blocks only the exact query. Use when a word is irrelevant in one specific context but relevant in others

Universal Negatives: Add These to Every Account

These terms are almost never relevant for a paid product or service and should be in every account's shared negative list:

• Intent negatives: free, cheap, budget, low cost, cheapest, discount, affordable (unless you sell on price)
• Learning intent: how to, tutorial, course, training, learn, DIY, guide (unless you sell educational content)
• Job/career: jobs, careers, salary, hiring, job openings, internship, resume
• Research intent: what is, definition, meaning, history, wiki, wikipedia
• Negative social proof: scam, fraud, lawsuit, complaints, fake
• Download/software: download, torrent, crack, free download

Industry-Specific Negatives

Beyond universal negatives, build a list specific to your industry. For a B2B SaaS product, add: student, nonprofit, personal, hobby, side project, consumer, individual. For ecommerce: wholesale, bulk, B2B (if B2C). For local services: nationwide, virtual, remote (if local-only).

How to Build Your List from Search Terms Data

The best source for negative keywords is your own account's search terms report. Here's the systematic process:

1. Download search terms report for the last 90 days, sorted by cost descending
2. Filter for queries with zero conversions and cost above your target CPC
3. For each term: is this someone who could realistically buy? If no → add as negative
4. Look for patterns: common word stems that appear in many irrelevant queries
5. Add stems as broad match negatives (catching the whole pattern, not just one query)

Negative Keyword Lists vs. Campaign-Level Negatives

Shared negative keyword lists (found in Tools → Negative keyword lists) let you apply a set of negatives to multiple campaigns at once. Create at least one account-level list for universal negatives. Then create campaign-specific lists for negatives that apply only to certain product lines.

Preventing Positive-Keyword Conflicts

A common mistake: adding a negative that inadvertently blocks a keyword you're actively bidding on. Before adding any negative, check whether it matches any of your active keywords. In the Negative keywords section, Google will warn you of conflicts — pay attention to these warnings.

Maintenance: Quarterly Negative Keyword Audits

Add the quarterly negative audit to your regular schedule: review search terms from the last 90 days, check if any existing negatives are over-blocking valuable traffic (use 'Added/Excluded' column in search terms), and refresh your industry-specific negatives based on new products or market changes.
