The Negative Keyword Audit: Cleaning Up a Live Search Terms Report
Objective: Given a real Search Terms report export and a Quality Score breakdown, identify which triggered queries are wasting spend and diagnose the weakest Ad Rank component, using the lesson's match-type and auction framework.
You're a paid search associate at Lenskart reviewing a broad-match eyewear campaign that has been live for three weeks with a rising cost per lead.
Find the irrelevant triggered queries burning budget, build a themed negative keyword list, and read the Quality Score breakdown to find the one component actually dragging down Ad Rank.
Before you start
What you'll need
Free path (everything below is enough to finish)
No account access needed, works entirely on the provided exports
Paid upgrades (optional, faster/deeper)
Surfaces waste patterns across hundreds of ad groups instead of a manual weekly scan
No access? The manual Google Sheets scan above catches the same waste at low query volume
The process
2 steps
Step 01 of 02
The lesson's warning callout on match types: broad match with zero negative keywords lets Google spend your budget on searches unrelated to your business, so the Search Terms report has to be checked weekly.
This 18-row Search Terms export is from a broad-match 'prescription eyeglasses' ad group. Which triggered queries should become negative keywords before next week's spend?
Procedure
- Import the export and freeze row 1
- Sort by Cost descending to see which queries consumed the most budget
- Flag every query with zero conversions and a clear intent mismatch
- Group flagged queries into negative keyword themes (repair, jobs, free, DIY)
Search Terms report (excerpt, sorted by cost) eyeglasses repair near me Cost $38.10 Clicks 22 Conv 0 prescription glasses jobs Cost $19.40 Clicks 11 Conv 0 free eyeglasses government Cost $16.70 Clicks 9 Conv 0 buy prescription eyeglasses Cost $61.20 Clicks 34 Conv 4 prescription eyeglasses online Cost $54.90 Clicks 29 Conv 3
Healthy
The three zero-conversion, intent-mismatched rows (repair, jobs, free/government) become negatives; the two converting rows stay untouched and may get their own tighter ad group.
Unhealthy
Treating every low-converting row the same and cutting 'prescription eyeglasses online' along with the true negatives, which removes a query that is already converting.
What this means
A negative keyword decision is about intent mismatch, not just a low conversion count on its own.
So what do I do about it?
| Symptom | Action | Effort |
|---|---|---|
| Cost per lead has been climbing week over week with no ad or bid changes | Pull the Search Terms report and check it before touching bids or budget | 5 min |
Step 02 of 02
Ad Rank = Bid x Quality Score x expected impact of ad extensions. Quality Score itself is built from three components Google scores separately: Expected CTR, Ad Relevance, and Landing Page Experience.
This keyword's Quality Score is 4/10. Given the three-component breakdown below, which one lever, if fixed, most directly explains the low score?
Procedure
- Record Expected CTR, Ad Relevance, and Landing Page Experience for the keyword
- Compare each rating (Below Average / Average / Above Average) against the ad and landing page it maps to
- Identify which single component is rated Below Average
Keyword: prescription eyeglasses online Quality Score: 4/10 Expected CTR Average Ad Relevance Average Landing Page Experience Below Average Ad group's ads link to: lenskart.com/ (homepage)
Healthy
The diagnosis correctly names Landing Page Experience as the weak link, and the fix is a dedicated /eyeglasses/prescription landing page, not a rewritten ad.
Unhealthy
Rewriting ad headlines for another week when the ad itself is already rated Average, while the homepage-as-landing-page mismatch goes untouched.
What this means
Quality Score is diagnostic, not just a number: each of the three components points at a different fix.
So what do I do about it?
| Symptom | Action | Effort |
|---|---|---|
| Quality Score stays at 4-5/10 despite several rounds of new ad copy | Check Landing Page Experience specifically before writing another headline | 30 min |
Final deliverable
A themed negative keyword list (grouped by intent-mismatch category) plus a one-paragraph Quality Score diagnosis naming the single weakest component and its fix.
See a reference example
Warby Parker, prescription sunglasses ad group audit NEGATIVE KEYWORDS TO ADD repair: sunglasses repair, lens replacement free/jobs: free sunglasses, sunglasses warehouse jobs QUALITY SCORE DIAGNOSIS Keyword 'buy prescription sunglasses' scores 5/10. Expected CTR and Ad Relevance are both Average; Landing Page Experience is Below Average because the ad links to the general sunglasses category page instead of a prescription-specific page. Fix: build a dedicated /prescription-sunglasses landing page before touching ad copy.
Success criteria
You're done when you can:
- Correctly separates true intent-mismatch negatives from low-but-valid converting queries
- Names the single weakest Quality Score component from the breakdown, not a guess
- Ties the fix to the specific component diagnosed (landing page vs ad copy vs CTR)
