A negative keyword audit in Google Ads involves reviewing the search terms report to identify queries that triggered ads but are irrelevant to the business goal. Best practice is to audit weekly for new campaigns and monthly for established accounts. Negatives should be added using phrase or exact match to avoid blocking genuinely relevant traffic. Building shared negative keyword lists and applying them account-wide is the most efficient approach for multi-campaign accounts.
Negative keywords are the single most impactful way to reduce wasted spend in Google Ads. This checklist covers 20 audit checks across brand terms, competitor terms, funnel stage mismatches, and category exclusions — for both lead generation and ecommerce accounts.
✅ Key Takeaways
- Negative keywords block irrelevant queries before they waste budget
- Shared negative lists apply across campaigns — build them early
- Audit frequency: weekly for new campaigns, monthly for established ones
- Lead gen and ecommerce have different negative keyword priorities
- Match type affects negatives: exact, phrase, and broad negatives behave differently

Frequently Asked Questions
How often should I audit negative keywords?
Weekly for new campaigns (first 30 days), monthly for established accounts. High-spend campaigns warrant weekly review regardless of age.
What's the difference between campaign-level and account-level negatives?
Account-level (shared) negatives apply to all campaigns. Campaign-level negatives only block within that campaign. Build shared lists for universal exclusions, campaign-level for specific blocking.
Should I use exact, phrase, or broad match negatives?
Use exact match negatives for specific high-value terms you want to preserve in other contexts. Use phrase match for query patterns. Avoid broad match negatives — they can accidentally block relevant traffic.
Can negative keywords hurt my reach too much?
Yes. Over-negating is a real risk. Only add negatives when there is clear evidence of irrelevance (0 conversions, wrong intent). Review your impression share after major negative additions.
Do negative keywords apply to Performance Max?
Not directly — PMax uses account-level negative keyword lists and brand exclusions only. You cannot add negatives at the campaign level for PMax, which makes the search terms report analysis even more critical.
