Quality Score is a 1–10 diagnostic metric Google assigns at the keyword level, built from three components: Expected Click-Through Rate, Ad Relevance, and Landing Page Experience. It influences Ad Rank and the actual CPC you pay — a higher Quality Score means you pay less for the same position. Use it as a directional signal for where your account structure or landing pages need work, not as a KPI to chase in isolation.
Key takeaways
Quality Score is a lagging, keyword-level diagnostic built from historical data — it is not the real-time quality signal Google uses inside the auction. [1]
The three components — Expected CTR, Ad Relevance, and Landing Page Experience — each require a different fix, so always diagnose before acting.
A higher Quality Score directly lowers your cost-per-click: in competitive verticals, the CPC gap between a QS 4 and a QS 8 keyword can exceed $10–$30 per click.
Quality Score does not apply to Performance Max campaigns, where Google's machine learning manages relevance internally. [2]
Pausing a low-QS keyword without diagnosing its components is one of the costliest mistakes in account management — a QS 4 keyword can still be your best converter.
Key terms
Quality Score
A 1–10 keyword-level metric Google uses to estimate the relevance of your keyword, ad, and landing page relative to a user's search query.
Ad Rank
The value Google calculates in each auction to determine your ad's position and the actual CPC you pay, influenced by your bid, real-time quality signals, and expected ad extension impact.
Expected Click-Through Rate (CTR)
Google's prediction of how likely your ad is to be clicked for a specific keyword, benchmarked against other advertisers competing on that same keyword.
Landing Page Experience
Google's assessment of how relevant, useful, and trustworthy your landing page is for a user who clicks your ad, factoring in content relevance, page speed, and mobile-friendliness.
Ad Relevance
A Quality Score component that measures how closely your ad copy matches the intent of the search query associated with your keyword.

What is Quality Score and what does it actually measure?
Quality Score is Google's 1–10 estimate of the relevance and quality of your keyword, ad, and landing page relative to a user's search query. [1] This question came up in the r/googleads community, and it surfaces constantly because the metric is easy to misread. The score you see in the interface is a historical, aggregated snapshot — it is not the live quality calculation Google runs in each individual auction. Think of it as a report card that tells you where your account has structural problems, not a live grade you're being judged on in every auction.
Key Insight: The Quality Score in your interface is a lagging indicator. The real-time quality signal inside each auction can differ from what you see reported. This is why practitioners who obsess over moving the number week-to-week are solving the wrong problem — focus on the structural inputs instead.
What are the three components of Quality Score and how are they rated?
Each Quality Score is built from three components, rated "Below Average," "Average," or "Above Average" — and each one points to a different root cause. [1] Understanding which component is dragging your score down is the only way to apply the right fix efficiently.
1. Expected Click-Through Rate
Expected CTR is Google's prediction of how likely your ad is to be clicked for a specific keyword, adjusted for position and auction context, benchmarked against other advertisers competing on the same keyword. A "Below Average" rating typically means your ad copy isn't compelling for that keyword's intent, or your match types are pulling in queries that don't align with your ad. Negative keywords are one of the fastest levers here — irrelevant queries suppress your CTR and drag this component down. [3]
2. Ad Relevance
Ad Relevance measures how closely your ad copy reflects the intent of the search query tied to your keyword. [1] "Below Average" here almost always means your ad groups are too broad — one ad is serving too many semantically different keywords. Tightly-themed ad groups of 5–15 closely related keywords with tailored copy per theme is the current best-practice structure. [4] Single Keyword Ad Groups (SKAGs) were once the go-to fix, but they create significant management overhead with minimal additional benefit in the era of Responsive Search Ads.
3. Landing Page Experience
Landing Page Experience is Google's assessment of how relevant, useful, and trustworthy your landing page is for a searcher who clicks your ad — incorporating content relevance, page speed, mobile-friendliness, and site transparency. [1] This is the hardest and slowest component to improve because it requires development resources and has a long feedback loop. It is also the most commonly neglected because it sits outside the ad platform itself.
Best Practice: Before changing anything, add the component columns in the Keywords view: Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. Export, sort by impression volume, and look for patterns. If 80% of your "Below Average" ratings are in Landing Page Experience, that is where your resources go first — not into rewriting headlines.
How does Quality Score affect what you actually pay per click?
Quality Score feeds into Ad Rank, which determines your position in the auction and the actual CPC you pay. [5] The relationship is direct: a higher Quality Score lets you win a higher position at a lower bid, or hold the same position for less spend. Below is a simplified illustration of how this plays out across three advertisers:
Advertiser
Max CPC Bid
Quality Score
Ad Rank
Actual CPC Paid
Advertiser A
$5.00
8/10
40
~$2.50
Advertiser B
$8.00
4/10
32
~$5.00+
Advertiser C
$3.00
10/10
30
~$1.50
Advertiser A wins over Advertiser B despite bidding 37.5% less. Advertiser C achieves a competitive position at a fraction of the cost. In accounts I manage across competitive verticals like legal, insurance, and SaaS, the CPC difference between a QS 4 and a QS 8 keyword routinely runs $10–$30+ per click. Across thousands of clicks a month, structural Quality Score improvements translate directly into six-figure annual savings.
What Quality Score benchmarks should I target?
A score of 7–8 for non-branded commercial keywords is genuinely strong performance — don't benchmark against your branded terms, which almost always score 9–10 because intent alignment is near-perfect. For context on what the best Quality Score looks like in practice, here is the framework I use when auditing accounts:
Quality Score
Interpretation
Action Required
1–3
Critical — actively hurting efficiency
Pause or emergency triage immediately
4–5
Below average — paying premium CPCs for poor position
Prioritize all three components
6–7
Average — acceptable but inefficient
Optimize ad copy and landing pages
8–9
Strong — well-optimized
Maintain and monitor for degradation
10
Excellent — typically branded terms
Protect with consistent messaging
Common Mistake: Pausing keywords with low Quality Scores without diagnosing why they're low. A QS 4 keyword can still be your highest-converting term — it just needs structural work on ad copy and the landing page. Pausing removes a valuable keyword without addressing the underlying problem. If you're seeing this pattern, the discussion on low Quality Score with high conversion rate covers how to handle it.
How do I actually improve Quality Score?
Improve the inputs — not the score itself. Each component requires a different intervention, and working in priority order prevents wasted effort.
Build dedicated landing pages per campaign theme rather than routing all traffic to your homepage.
Make the conversion path obvious — a confused visitor bounces, and bounces hurt this component.
Step 2: Tighten ad group structure (for Ad Relevance issues)
Audit ad groups with more than 20 keywords — they are almost certainly too broad.
Group keywords by search intent, not just topic: "buy running shoes" and "running shoe reviews" serve different audiences and need different ads.
Write ad copy that directly reflects the keyword theme — if the keyword is "emergency plumber near me," the first headline should say "Emergency Plumber — Available Now." [6]
Use Dynamic Keyword Insertion strategically for large keyword lists, but do not rely on it as a substitute for genuine relevance.
Step 3: Optimize ad copy for Expected CTR
Lead with a specific, compelling value proposition in your first or second headline.
Use concrete numbers: "Save 40%," "Ships in 24 Hours," "4.9★ Rating (2,000+ Reviews)."
Match your CTA to funnel stage — "Get a Free Quote" outperforms "Learn More" for bottom-funnel commercial intent.
Review your Search Terms Report regularly to identify irrelevant queries lowering CTR, then add negatives. [7] This is both a waste-reduction lever and a Quality Score lever.
Common Mistake: Writing clickbait ad copy to inflate CTR. Expected CTR may improve, but you attract unqualified clicks, conversion rate tanks, and ROAS suffers. Always optimize Quality Score components through the lens of relevance and intent — the score should follow from doing things right, not from gaming individual signals.
Best Practice: Build a monthly Quality Score audit into your management rhythm. Export keyword-level QS data with all three component scores, filter for keywords with >100 impressions and QS <6, then sort by impression volume × CPC. This keeps your effort focused on the keywords where fixing a structural problem has the largest dollar impact. Our 250-point Google Ads audit engine surfaces these patterns automatically.
Where does Quality Score not apply?
Quality Score is a Search campaign metric with specific blind spots every practitioner should know.
New keywords with low impressions: Google reports "—" until roughly 1,000 impressions have accumulated. Do not make structural decisions during this period.
Performance Max campaigns: Quality Score does not apply here at all — Google's machine learning handles relevance internally. [2]
Display Network: Quality Score for display campaigns is calculated differently and is a less reliable optimization signal than on Search.
Highly competitive niches: In verticals like legal services, finance, or healthcare, even well-optimized accounts regularly see QS 6–7 for non-branded terms because the competitive baseline is extraordinarily high. A 7 in personal injury law is the equivalent of a 9 in most other categories.
Always cross-reference Quality Score with actual performance metrics — conversion rate, CPA, ROAS — before making structural decisions. It is a useful directional signal, not gospel. For a broader take on how much weight to give this metric, the debate around whether Quality Score is a distraction is worth reading.
What to do next
Add the component columns now. In Keywords view, add Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. Export and sort by impression volume descending — this is your prioritized work list.
Identify your worst offenders. Filter for keywords with QS 1–5 and more than 500 monthly impressions. These are costing you the most in inflated CPCs right now.
Run a landing page speed audit. Take your top 10 landing pages by spend, run them through Google PageSpeed Insights, and flag anything scoring below 70 on mobile. Speed improvements alone can shift Landing Page Experience from Below Average to Average.
Restructure one problem campaign. Pick the campaign with the lowest average Quality Score and tighten its ad groups — aim for closely-themed groupings with tailored Responsive Search Ad copy per theme. In accounts I manage, this alone routinely produces QS improvements of 2–3 points within 30–60 days.
Purge irrelevant search terms. Open the Search Terms Report for your broad and phrase match keywords and add negatives aggressively. [7] Irrelevant queries are one of the fastest CTR suppressors in any account.
Frequently asked questions
Is a Quality Score of 7 out of 10 actually good?
For non-branded commercial keywords, a 7/10 is genuinely strong — not a cause for alarm. Branded terms almost always score 9–10 because intent alignment is near-perfect, so comparing your non-branded QS to your branded QS will always look unfavorable. In competitive verticals like legal or finance, a 7 represents well-optimized performance. See the full breakdown of what a 7/10 Quality Score means in practice.
Should I pause keywords just because they have a low Quality Score?
Not automatically. A low QS keyword can still be your best-converting term — the score reflects structural issues in your ad copy or landing page, not the keyword's commercial value. Diagnose which component is Below Average first. If you pause without fixing the root cause, you lose the keyword and the underlying problem remains. Triage before you cut.
Why does my Quality Score show a dash (—) instead of a number?
Google requires a minimum impression volume — typically around 1,000 impressions — before it calculates and displays a Quality Score for a keyword. New keywords or very low-volume terms will show "—" until enough data accumulates. This is normal. Do not restructure ad groups or pause keywords purely because of a missing score during this early data-gathering period.
Does Quality Score directly affect my Performance Max campaigns?
No. Quality Score is a Search campaign metric and does not apply to Performance Max campaigns at all. [2] In Performance Max, Google's machine learning handles ad relevance and audience matching internally across all channels. The diagnostic framework described in this article applies to Search campaigns only.
My Google Ads rep told me Quality Score doesn't matter anymore. Are they right?
Partially, and it depends on what they mean. Quality Score as a KPI to obsess over weekly is less important than optimizing the underlying inputs. But the inputs themselves — landing page relevance, ad copy alignment, CTR — absolutely still affect Ad Rank and the CPC you pay in every auction. Dismissing Quality Score entirely means ignoring a useful diagnostic. The full discussion on ignoring Quality Score unpacks where that advice goes wrong.
How long does it take to see Quality Score improve after making changes?
Landing Page Experience has the longest feedback loop — changes can take several weeks to register because Google needs to recrawl and re-evaluate pages, then accumulate new impression data. Ad Relevance improvements from ad group restructuring typically show within 2–4 weeks. Expected CTR changes driven by new ad copy or negative keyword additions can surface faster, often within 2–3 weeks of sufficient impression volume.
