Negative Keywords
Keywords you add to your campaigns to prevent ads from showing for irrelevant searches.
Definition
Negative keywords are words or phrases that, when included in a search query, prevent your Google Ad from showing. They are one of the most powerful levers for improving campaign efficiency — stopping your budget from being wasted on searchers with no intent to buy. For healthcare practices, a strong negative keyword list is often the difference between a profitable and unprofitable account.
The Practitioner's Perspective
Negative keywords come in three match types: Broad Negative (blocks any query containing the word in any form), Phrase Negative (blocks queries containing the exact phrase), and Exact Negative (blocks only the exact query). For healthcare, common negative themes include insurance-related terms (you don't bill insurance), DIY/home-remedy terms, competitor-specific terms that aren't targeting opportunities, job-seeking terms, and research-intent terms that won't convert.
Building a comprehensive negative keyword list is an ongoing process, not a one-time setup. Every week, review your Search Terms report to identify new queries that wasted budget. Over time, you accumulate a powerful exclusion list that makes your campaigns dramatically more efficient. Agencies managing healthcare accounts often maintain negative keyword lists of 500–2,000+ terms across industry, geography, and intent categories.
Negative keyword lists can be shared across multiple campaigns using Shared Lists, which is a significant time-saver for accounts with multiple campaigns targeting similar geographies and procedures. Create master lists by category — insurance terms, DIY terms, research terms — and apply them to relevant campaign groups. When you discover a new negative in one campaign, add it to the shared list to protect all campaigns simultaneously.
Frequently Asked Questions
What negative keywords should a medical spa use?
Key categories: insurance-related ('does insurance cover', 'insurance accepted'), DIY/at-home ('at home botox', 'DIY filler'), budget signals ('cheap', 'free'), research intent ('what is botox', 'how does botox work' if you're targeting buyers not researchers), and job terms ('botox jobs', 'aesthetician career').
How often should I update my negative keywords?
Weekly during the first 3 months of a campaign, then bi-weekly ongoing. Search behavior evolves — new irrelevant queries emerge over time. Consistent Search Terms report review is the single highest-ROI maintenance task in a healthcare Google Ads account.
Can negative keywords accidentally block good traffic?
Yes — this is called 'negative keyword conflict'. If you add a negative keyword that overlaps with your positive keywords, you'll block your own ads. Google Ads Editor has a conflict checker. Audit your negative list quarterly to identify accidental blocks.
