What Is Google Ads Quality Score?
Quality Score is Google’s estimate of the quality and relevance of your ads, keywords, and landing pages, reported at the keyword level on a scale of 1 to 10. It is not a vanity metric: it feeds directly into Ad Rank, which decides whether your ad shows at all and how much you pay when it does. Two advertisers can bid $8.00 on the same keyword and pay wildly different amounts — the one with stronger quality signals might pay $5.20 while the one with weak relevance pays $9.80 and still ranks below.
Every keyword gets its own score, computed from real-time and historical performance across the auction. Google evaluates three component statuses — Expected Clickthrough Rate, Ad Relevance, and Landing Page Experience — each rated as Above average, Average, or Below average. The 1-10 number is a synthesis of those components plus signals Google does not disclose.
The Three Reported Components
| Component | What Google Measures | Common Cause of a Below Average Rating |
|---|---|---|
| Expected CTR | How likely your ad was to be clicked when shown for that query, adjusted for position, assets, and your historical clickthrough rate | Generic copy that could describe any company, no call to action, and broad keywords stuffed into one ad group |
| Ad Relevance | How closely your ad copy matches the intent behind the keyword | One ad group targeting dozens of unrelated terms, or the keyword missing from the headline entirely |
| Landing Page Experience | Relevance and usefulness of the page: original content, load speed, mobile usability, and clear alignment with the ad promise | Sending traffic to the homepage, slow mobile pages, thin or duplicated content, popups that block the answer |
Check the components before touching anything else. A keyword rated Average / Average / Below average needs a landing page fix, not new ad copy — advertisers routinely spend weeks rewriting headlines when the actual leak is the page behind the ad.
How Quality Score Affects Ad Rank and CPC
The auction formula is simple to state: Ad Rank = bid × quality factors (+ ad assets impact). Your actual CPC is then calculated as the Ad Rank you needed to beat, divided by your quality factors, plus $0.01. High quality acts like a bid multiplier; low quality acts like a tax.
Google no longer publishes an official CPC adjustment table, but the mechanic has not changed, and the adjustments Google disclosed in earlier years remain the best public reference for what quality is worth:
| Quality Score | Historical CPC Adjustment vs. QS 5 Baseline | What It Means in Practice |
|---|---|---|
| 10 | -50% | You pay half the going rate for the same position |
| 8-9 | -30% to -40% | Consistent discount; budget stretches noticeably further |
| 6-7 | -10% to -20% | Healthy; most well-run accounts live here |
| 5 | Baseline | Average — no discount, no penalty |
| 3-4 | +25% to +65% | Paying a premium just to appear; budget drains fast |
| 1-2 | +80% to +400% | Severe penalty; keywords rarely show at acceptable cost |
Run the math on a real budget: an account spending $6,000 per month at an average Quality Score of 4 versus the same account at 7 can expect roughly 30-50% more clicks from identical spend once the discount compounds through the auction. That is why quality work almost always beats raising bids — published Google Ads cost benchmarks show CPC inflation of 5-10% year over year, and quality is the only variable that moves in the opposite direction.
Quality Score vs. Ad Rank: What Actually Gets Scored
A common trap is chasing the 1-10 number itself. The reported score is a diagnostic, not the auction input. The auction uses the underlying quality factors at the moment of each search — including context signals the reported score ignores, such as the searcher’s device, location, time of day, and the other ads competing in that instant.
Two practical consequences follow. First, a keyword showing a reported 6 can still win auctions cheaply in contexts where its relevance is strong. Second, Ad Rank thresholds mean some queries — medical, financial, legal — demand a minimum quality bar regardless of bid. A $25 bid with weak relevance will not buy its way into those auctions. Google’s own documentation on how Quality Score works frames the score as an estimate of relevance, and the auction as the place where that estimate gets cashed in.
This distinction also explains why Performance Max and Demand Gen campaigns report no keyword-level scores at all: those campaign types evaluate quality dynamically per impression rather than per keyword. Advertisers consolidating everything into asset-based campaign types lose the diagnostic — a real cost, which is why we recommend keeping at least one search campaign structure alongside Performance Max so quality data keeps flowing into the account.
The Factors That Move Quality Score
Google confirms three reported components, but accounts that consistently score 8-10 tend to perform well on a longer list of inputs:
Historical clickthrough rate. Your account’s past performance on similar queries is the strongest single signal. Keywords inherit the reputation of the ads and queries they have matched to, which is why search term hygiene compounds: every junk click today quietly lowers tomorrow’s expected CTR.
Ad copy relevance and specificity. Headlines containing the query’s core intent (not necessarily the literal keyword) consistently outperform clever-but-vague copy. Numbers, prices, and concrete outcomes raise CTR in almost every vertical we audit at Digimau.
Landing page speed and mobile experience. Pages that load in under 2.5 seconds on mobile and keep the ad’s promise above the fold convert and score better. A full Google Ads landing page setup covers the technical checklist; the short version is that page experience is now inseparable from paid quality.
Ad assets (formerly extensions). Sitelinks, callouts, structured snippets, and image assets raise absolute CTR, and expected CTR is measured relative to what was possible — an ad with a full asset set has a higher achievable ceiling, which lifts the rating.
Account structure. Tight keyword themes per ad group, mirrored ad variations, and one clear landing page intent per ad group remain the structural backbone of high scores, even in the era of broad match and smart bidding.
Geographic and device performance. Quality is contextual. The same keyword can be Above average in Texas and Below average in Quebec; strong accounts review scores by campaign geography rather than only at the account level.
How to Check Your Quality Score
The score is hidden by default. In the Google Ads interface, add the Qual. score column (Keywords → Columns → Modify columns → Quality Score) along with the three component status columns. Segment nothing at first: look at the keyword-level distribution across the account.
Sort by spend-weighted score. The question that matters is not how many keywords score 4, but how much of your monthly budget flows through keywords scoring 4 or lower. A 2,000-keyword account where 95% of spend sits on 40 keywords scoring 7+ is healthy; a 300-keyword account where 60% of spend hits keywords scoring 3-4 is bleeding, regardless of averages.
Review scores monthly, not daily — component statuses update on a lag and react slowly to fixes. Give any structural change two to four weeks before judging its effect, then compare the spend-weighted average rather than the simple mean.
Seven Fixes That Raise Quality Score
1. Split ad groups by theme. Break mega ad groups into groups of 5-15 tightly related keywords. If your ad group contains both liability insurance and commercial auto coverage, neither ad can be maximally relevant to both. This single change resolves most Below average relevance ratings within a month.
2. Insert the ad group’s core intent into headlines. You do not need exact keyword insertion everywhere, but each ad variation should echo the search intent in at least two of the fifteen available headline slots. Responsive search ads give you room to test intent-matched copy against benefit-led copy.
3. Send traffic to the most specific page that exists. If the keyword is commercial awning repair, the landing page should be about awning repair — not your services overview. Where no specific page exists, build one. Advertisers who map every high-spend keyword to a dedicated page routinely see landing page ratings flip from Below average to Average or Above average in one cycle.
4. Fix mobile speed before creative. Compress images, defer non-critical scripts, and check Core Web Vitals for the exact landing URLs ads point to. Pages above 4 seconds on 4G waste both score and conversion rate.
5. Prune search terms weekly. Add search terms that convert badly or mean something else entirely as negative keywords. Cleaning the query stream lifts historical CTR, which is the deepest input to expected CTR.
6. Expand assets aggressively. Fill every asset slot: four or more sitelinks, callouts, structured snippets, images, and where relevant lead forms or calls. Assets raise real CTR and widen your expected CTR ceiling.
7. Steal context from competitors. Studying what rivals run — their angles, offers, and landing pages — shortens the copy testing loop dramatically. Tools and workflows for finding competitor ads are free for Google and Meta, and the intelligence compounds. Pair creative intelligence with the keyword-level method in our competitor keyword guide to see both sides of their acquisition strategy.
What Is a Good Quality Score in 2026?
Context decides the target. Branded keywords should score 9-10; generic commercial keywords scoring 6-8 are doing well; long-tail informational terms can be uneconomical even at 5 if the product is unrelated to the query. Use this table to set targets by keyword tier:
| Keyword Tier | Good Score | Investigate If Below | Typical First Fix |
|---|---|---|---|
| Branded terms | 9-10 | 8 | Add brand sitelinks and protect with exact match |
| Core commercial terms | 7-8 | 5 | Tighten ad group theme, intent-match headlines |
| Comparison / high-intent long tail | 6-7 | 4 | Dedicated landing page for the comparison intent |
| Informational terms | 5-6 | 3 | Reconsider goal — often better served by SEO content |
If an account’s spend-weighted average sits at 6 or above across search campaigns, quality is not the constraint on growth — budget, offer, or conversion rate probably is. Below 5, quality work typically returns more than any bid increase. For teams rebuilding an acquisition program from scratch, our competitor analysis framework covers the research phase, and the remarketing playbook covers how to monetize the clicks quality improvements bring you.
Quality Score rewards the same discipline that makes campaigns profitable in every other sense: specific structure, honest promises, and fast relevant pages. Fix those three and the score follows.
Frequently Asked Questions
What is a good Quality Score in Google Ads?
A score of 7 or higher is good for core commercial keywords, and 9-10 is excellent and typical for branded terms. Scores of 5 are average, and anything at 4 or below usually means you are paying a CPC premium of 25% or more for the same positions.
Does Quality Score directly lower my CPC?
Yes. The auction divides the Ad Rank you must beat by your quality factors, so higher quality means a lower actual CPC for the same position. Google’s historical adjustments ranged from a 50% discount at QS 10 to penalties exceeding 80% at QS 1-2.
Why did my Quality Score drop suddenly?
Common causes include new competitors with stronger ads, landing page changes that slowed the page or broke the ad-to-page message match, ad group expansions that diluted relevance, and rising CTR benchmarks in your vertical as creative standards improve.
How long does it take to improve Quality Score?
Component statuses typically respond within 2-4 weeks of a fix. Structural changes like splitting ad groups can lift relevance ratings in one update cycle, while expected CTR recovers more slowly because it depends on accumulated query history.
Do Quality Scores matter for Performance Max campaigns?
Performance Max does not report keyword-level Quality Scores because it has no keyword targets. Quality still matters inside those auctions, but it is evaluated per impression. Keep a standard search campaign running alongside PMax to retain the diagnostic.
Can I have a high bid with a low Quality Score and still win?
Sometimes, but expensively. A high bid can compensate for weak quality up to the Ad Rank threshold, and on sensitive categories like healthcare and finance the threshold can exclude weak-relevance ads no matter the bid. Winning this way burns budget that competitors spend profitably.
Does Quality Score affect how often my ads show?
Yes. Ad Rank determines eligibility for the top positions and for showing at all in competitive auctions, so low quality reduces impression share even when your bid is competitive. Low Ad Rank from quality is one of the most common causes of Lost IS (rank).
Should I pause keywords with a Quality Score of 3 or lower?
First diagnose, then decide. If the keyword is commercially important, split it into a tighter ad group with intent-matched copy and a dedicated page. If the keyword is peripheral and unrelated to your offer, pause it or make it negative — a low score on an irrelevant term is Google protecting you from spending.
Do landing pages affect Quality Score more than ad copy?
They matter at least as much. Ad Relevance and Expected CTR get attention, but Landing Page Experience is the component advertisers can control most objectively — speed, mobile usability, relevance, and original content — and it is the most common Below average rating we find in audits.
Is Quality Score the same on the Search and Display networks?
The 1-10 reported score applies to Search keywords. Display and video campaigns are evaluated on quality-related signals too, but they report different diagnostics, and the CPC adjustment mechanics are not published. Focus the 1-10 score work on search campaigns.
