Negative keywords are the single fastest way to recover wasted spend in B2B SaaS Google Ads. Our audit of 43 enterprise accounts found $4.87 million lost to irrelevant search terms — the #1 waste pattern by dollar volume. And the fix takes less than an hour: add the right negative keywords and the bleeding stops immediately.
After auditing 300+ B2B SaaS accounts at GrowthSpree, we’ve compiled the definitive negative keyword list organized into 8 categories. Each category represents a pattern of wasted spend we see repeatedly. The list below is the template. Customize it for your specific product, but start here — 80% of these negatives apply to nearly every B2B SaaS account.
Category 1: Educational and Informational Intent (Blocks Researchers and Students)
These searchers want to learn, not buy. They’re students, analysts writing reports, or professionals researching for certifications. They click your ad, consume your content, and never fill out a demo form.
Negative keywords: course, courses, tutorial, tutorials, certification, certifications, training, class, classes, degree, university, college, school, academic, student, scholarship, syllabus, curriculum, textbook, exam, quiz, study, learn, learning, education, educational, define, definition, what is, meaning of, explain, example, examples, pdf, ppt, presentation, paper, thesis, dissertation, free course, online course
These 40 negatives alone typically eliminate 8–15% of non-brand wasted spend.
Category 2: Job and Career Searches (Blocks Job Seekers)
Job seekers searching for roles that include your product category. “Data governance” triggers both buyers and people looking for data governance analyst jobs.
Negative keywords: jobs, job, careers, career, hiring, vacancy, vacancies, salary, salaries, compensation, resume, CV, interview, recruiter, recruiting, recruitment, glassdoor, indeed, linkedin jobs, work from home, remote job, internship, intern, entry level, junior, associate, coordinator
Category 3: Competitor Brand Names (Blocks Competitor-Loyal Searchers)
Unless you have dedicated competitive conquest campaigns with comparison landing pages, competitor name searches waste budget. The searcher wants Competitor X, not your product.
Negative keywords (customize for your market): [Competitor A name], [Competitor B name], [Competitor C name], login, sign in, dashboard, support, documentation, docs, status page, pricing page (when preceded by competitor name). Add all major competitor brand names as phrase match negatives at the account level.
Category 4: Free and Open Source (Blocks Non-Paying Intent)
If you sell commercial software, these searches indicate the user isn’t willing to pay. They want a free alternative, not a demo.
Negative keywords: free, freeware, open source, open-source, free trial (if you don’t offer trials), free download, free tool, free software, free version, free alternative, cracked, pirated, torrent, github, community edition
Category 5: Unrelated Products Sharing Your Keywords (Product Name Collision)
If your product name or category overlaps with non-software products, you’ll attract irrelevant clicks. This is the $10K+ category from our $145K account audit where “brand keyword” triggered searches for HR platforms, CRM features, university tools, and industrial IoT products.
Negative keywords (highly account-specific): [your product name] + HR, people, employee, hubspot, salesforce, bloomberg, university, [any brand that shares your product name keywords]. Run a search term report for the last 90 days and extract every non-relevant product or platform that appeared.
Category 6: Overly Generic and Ambiguous Terms (Blocks Random Browsers)
Negative keywords: what is, how to, meaning, definition, vs, versus (unless in competitive campaigns), review, reviews, reddit, quora, forum, blog, article, news, comparison, compare, list, top 10, best (use selectively — “best [category]” can be high intent)
Category 7: Wrong Geography or Language (Blocks Non-Target Markets)
If you only sell in the US, add negatives for non-target country searches.
Negative keywords: uk, united kingdom, australia, canadian, india, deutsch, french, espanol, en español (and any non-English language terms that trigger from your keywords)
Category 8: Support and Existing Customer Queries (Blocks Non-Prospect Intent)
Your own customers searching for support documentation will trigger ads. You’re paying to reach people who already bought.
Negative keywords: login, log in, sign in, support, help, documentation, docs, API, bug, error, issue, troubleshoot, download, update, upgrade, cancel, cancellation, refund
Implementation: How to Deploy These Negative Keywords
Step 1: Account-level negatives. Categories 1, 2, 4, 6, 7, and 8 should be added as account-level negative keyword lists. These apply to every campaign.
Step 2: Campaign-level negatives. Category 3 (competitors) should be applied to all campaigns except dedicated competitive conquest campaigns. Category 5 (product name collisions) should be applied to all campaigns.
Step 3: Ad group-level negatives. Add specific negatives for each ad group based on search term analysis. Example: the “metadata” ad group should exclude “module,” “file,” “image,” “video” to block programming context searches.
Step 4: Weekly maintenance. Review the search terms report every Monday for the first 90 days. Add any new irrelevant terms as negatives. Use Google Ads MCP to automate this through AI.

FAQ: Negative Keywords for B2B SaaS Google Ads
How many negative keywords should a B2B SaaS Google Ads account have?
A healthy B2B SaaS account typically has 200–500 negative keywords across account, campaign, and ad group levels. Start with the 200+ terms in the template above, then add 20–50 per month from ongoing search term analysis. The list should grow continuously — if your negative keyword list hasn’t changed in 3 months, nobody is maintaining it.
Should I use broad, phrase, or exact match for negative keywords?
Use phrase match for most negative keywords. Phrase match negatives block any search that contains that phrase, which is appropriate for most categories (e.g., phrase match “certification” blocks “AI governance certification,” “data governance certification,” etc.). Use exact match negatives only when a phrase match would be too restrictive — for example, exact match [free] if you don’t want to block “free trial” but do want to block “free data catalog.”
How much money can negative keywords save in B2B SaaS?
Based on our audits of 300+ B2B SaaS accounts, proper negative keyword implementation typically recovers 10–25% of total ad spend. For a $50K/month account, that’s $5K–$12.5K per month in recovered budget — immediately available for reallocation to converting campaigns. The savings are front-loaded: the first 100 negatives typically capture 80% of the waste. Ongoing weekly maintenance captures the remaining 20% incrementally.
