Conducting regular search term audits represents a core campaign maintenance exercise for software media buyers. In B2B SaaS paid search, bidding on broad match keywords can drive up click costs on educational and non-commercial queries. Reviewing and filtering out these low-intent terms ensures your ad spend is directed exclusively to prospects with buying power. To understand how search term audits align with your broader search campaign architecture, read our comprehensive B2B SaaS Performance Marketing Guide which outlines our keyword match type rules.

1. Why Search Term Audits are Critical
In paid search, keywords are not the same as search terms. You bid on keywords, but you pay for search terms (the exact queries users type). If you bid on the keyword “crm software,” Google might match your ad to “free crm software tutorial,” driving up click costs on non-buying traffic.
Search term audits allow you to see exactly what queries triggered your ads, allowing you to add negative keywords to block waste spend, protecting your acquisition margins.
Without regular audits, campaign Quality Scores decline as CTRs drop on irrelevant search queries, raising your average CPC and overall acquisition costs.
Regular audits also highlight new keyword patterns. If you identify a high-volume search term that converts well, adding it as an exact keyword allows you to set custom bids, raising traffic volume.
2. Distinguishing Educational vs. Commercial Intent
Classify user intent by analyzing search patterns. Educational queries focus on learning (e.g. “what is pipeline velocity”). Commercial and transactional queries focus on evaluation and purchase (e.g. “crm pricing tiers”).
B2B SaaS campaigns must focus on commercial intent. Filter out search terms containing informational queries like “career,” “salary,” “resume,” “free,” and “classes” immediately, ensuring your budget is saved for target buyers.
3. Building Master Negative Keyword Lists
Create a master negative keyword list containing these non-commercial terms and apply it across all search campaigns. Below is our standard B2B SaaS negative keyword list:
| Negative Category | Negative Keywords (Broad Match) | Attribution Protection Goal |
|---|---|---|
| Career / HR | job, salary, resume, career, internship, hiring | Filter out job seekers and recruiters |
| Education / Tutorials | class, course, book, guide, tutorial, pdf, what is | Filter out students and research queries |
| Existing Customers | login, support, sign in, portal, api doc | Filter out active customers looking to log in |
4. The Impact of Match Types on Query Volume
Keyword match types (Exact, Phrase, Broad) determine how closely a search query must match your keyword. While exact match keywords provide tight control, they limit campaign scale.
Broad match keywords capture a high volume of search queries, but require aggressive negative lists to prevent matching to low-intent terms, balancing scale with efficiency.
5. Automated Scripts for Search Term Audits
Manually auditing search reports is time-consuming. You can implement Google Ads scripts to automate the review process. Below is a standard Python-ready script schema that filters out search terms containing negative query lists:
# Example Google Ads script logic (JavaScript-based)
def main():
report = AdsApp.report(
"SELECT SearchTermView.SearchTerm, Metrics.Clicks, Metrics.Cost FROM SEARCH_TERM_VIEW WHERE Metrics.Cost > 50 AND Metrics.Conversions = 0 DURING LAST_30_DAYS"
)
# Filter search terms locally and flag for negative additions
Configure similar scripts to run weekly, alerting your media buyers to add high-cost, zero-conversion search terms as negative keywords automatically.
6. Smart Bidding and Broad Match Synergy
If you use Google’s automated bidding models (like Target CPA), combining broad match keywords with strict smart bidding allows Google’s algorithm to analyze user intent signals in real-time.
However, you must maintain your negative keyword lists. Smart bidding cannot foresee external events (such as new competitor product releases or PR events), requiring manual negative audits to keep campaigns on track.
7. Filtering Out Competitor Brand Clashes
Search term audits often highlight that your ads are displayed on competitor brand searches. If you bid on the broad keyword “crm software,” your ad might appear for “HubSpot CRM login.”
If competitor brand clicks are driving high costs without conversions, add competitor brand names as negative keywords to keep your budget focused on category terms.
8. Quality Score Calculations and Search Term Relevancy
Google Ads calculates Quality Scores based on expected CTR, ad relevance, and landing page experience. If your campaigns match to educational search terms, ad CTRs will naturally drop as users seek landing pages with informational resources rather than demo forms. Regular negative keyword audits keep your matched queries highly relevant, boosting Quality Scores and lowering your average CPC.
9. Standard negative list exclusions
Consolidate your negative keywords into shared library lists. Apply lists like “Job Search Terms” and “Customer Login Terms” across all active search campaigns, ensuring that any new search campaign immediately inherits these exclusions, keeping keyword pools clean.
11. Negative Match Types Rules
Understand the rules governing negative keyword match types (Exact, Phrase, Broad). Adding a negative keyword as a broad match (e.g. -free) blocks all search terms containing that word, regardless of order.
Conversely, exact match negatives (e.g. -[free crm]) only block searches matching the exact phrase, allowing related queries (like “free CRM software”) to trigger ads. B2B media buyers must use phrase match negatives to block specific low-intent queries while maintaining campaign scale.
Regularly audit your ad account for negative keyword conflicts. Google Ads flags occurrences where a newly added negative keyword blocks search terms that match your active keywords. Resolving these alerts immediately prevents accidental impressions drops. Executing this cleanup step weekly maintains active campaign health.
Set up a regular, recurring calendar notification to audit search terms every Friday afternoon. Reviewing search queries weekly prevents minor non-commercial keyword matches from accumulating high spend, preserving campaign efficiency. This discipline keeps negative keyword list optimizations accurate.
Ensure you filter out student and researcher queries. B2B campaigns must exclude terms like “classroom,” “exam,” and “syllabus” to prevent academic traffic from depleting budgets meant for commercial procurement targets. This filtering maintains a clean search traffic pool.
Organize negative keywords systematically. Creating a dedicated negative list for each primary search campaign ensures you do not block queries that are relevant to secondary campaigns, preserving traffic flow. Visual checklist updates help you spot negative conflicts early.
10. Frequently Asked Questions
What is the difference between keywords and search terms?
Keywords are the target terms you bid on inside your ad account. Search terms are the actual queries users type on Google that trigger your ads.
Should I add all competitor names as negatives?
Only if you are not running dedicated competitor conquesting campaigns. If competitor clicks are driving high costs with zero sales opportunity, negative list them.
What is a master negative list?
A reusable list of negative keywords configured inside your ad account library that can be applied to multiple search campaigns simultaneously, simplifying maintenance.
Should I use broad match keywords?
Only when combined with smart bidding models and comprehensive negative lists. For new accounts, start with exact and phrase match keywords to establish a baseline.
