Negative Keywords & Search Term Reports
Negative keywords are the single most misunderstood money-saving tool in Google Ads. They prevent your ads from showing for irrelevant searches, eliminating wasted spend and improving campaign Quality Scores. A well-built negative keyword list can reduce wasted budget by 20-40%, improving ROAS without increasing spend.
How Negative Keywords Work
- Adding a negative keyword tells Google: 'Do NOT show my ads when this term appears in the search query'
- Example: A premium Google Ads agency adds negative keywords: 'free', 'cheap', 'DIY', 'how to', 'course', 'tutorial' - preventing budget waste on people not looking to hire an agency
- Match types apply to negatives too: Negative Broad (blocks any search containing the word), Negative Phrase (blocks searches containing the exact phrase), Negative Exact (blocks only that specific query)
Reading the Search Terms Report
- Location: Campaigns → Keywords → Search Terms tab
- What it shows: The actual search queries that triggered your ads - not just the keywords you bid on
- Weekly task: Review the Search Terms Report and add irrelevant, low-intent, or competitor-adjacent terms as negatives
- Adding converting terms: If you see a search term converting well that you're not explicitly bidding on, add it as a keyword
- Negative keyword lists: Build a 'Master Negative' list containing universal terms irrelevant to your business and apply it across all campaigns
Starter Negative Keywords for Most Businesses
- Intent negatives: 'free', 'cheap', 'diy', 'how to', 'what is', 'definition', 'meaning of', 'example'
- Job/career negatives: 'jobs', 'careers', 'salary', 'resume', 'glassdoor', 'intern'
- Educational negatives: 'course', 'tutorial', 'training', 'certification', 'learn', 'study'
- Add competitor brand names as negatives (unless running a competitor campaign intentionally)
