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

The typical Google Ads account wastes 15-25% of its budget on irrelevant clicks. On a $3,000/month budget, that's $450-$750 per month going to people who will never buy. Negative keywords are the most direct way to stop this leak — and their benefit compounds: better traffic = higher CTR = better Quality Score = lower CPC for everyone.

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
