Google Ads Quality Score: What Actually Moves the Needle in 2026
Quality Score is one of those Google Ads metrics that everyone talks about and almost nobody understands well. The conventional wisdom — “improve your Quality Score to lower CPC” — is technically right but practically useless without knowing which levers actually move it. In the Smart Bidding era, the question is even more confused: does Quality Score still matter when the algorithm decides bids?
Yes, it still matters. Quality Score is a signal that compounds with Smart Bidding, not one that’s replaced by it. This guide walks through what Quality Score really measures in 2026, how to read it, and the specific actions that move each component.
What Quality Score actually is
Quality Score is Google’s 1-10 rating of your keyword’s relevance and likely user experience. It has three components, each rated “Above average”, “Average”, or “Below average”:
1. Expected CTR: how likely users are to click your ad when it shows for this keyword.
2. Ad relevance: how well your ad copy matches the keyword’s search intent.
3. Landing page experience: how relevant, useful, and well-designed your landing page is for users coming from this keyword.
The 1-10 score is a rollup of these three. Higher score → better Ad Rank → lower CPC for the same position, or better position for the same bid.
Why Quality Score still matters in Smart Bidding era
A common confusion: “Smart Bidding picks bids automatically, so Quality Score doesn’t matter, right?”
Wrong. Smart Bidding still bids in the same auction. Quality Score still affects:
- Ad Rank: the threshold to enter the auction and your position in it
- Effective CPC: the actual amount you pay when you win an auction
- Reach: whether your ad qualifies for various ad positions and surfaces
- Smart Bidding’s room to operate: better Quality Score → more auction opportunities at sustainable bids
A campaign with 8/10 average Quality Score pays 30-50% less per click than the same campaign with 4/10 Quality Score, even with identical Smart Bidding strategy.
Where to find Quality Score
In Google Ads → Keywords → Modify columns → add Quality Score columns:
- Quality Score (1-10)
- Expected CTR
- Ad relevance
- Landing page experience
The components are usually more actionable than the rollup score. If your Quality Score is 5/10, knowing whether Expected CTR or Landing page experience is the problem tells you what to fix.
Lever 1: Expected CTR
What it measures: how often users click your ad relative to what Google expects.
What moves it:
Tighter keyword-to-ad match. Ads with the keyword in the headline outperform ads that don’t. Smart Bidding has moved this further: broad-match keywords benefit from headlines that match the intent of the variations, not just exact word match.
Stronger calls to action. “Get a free audit” beats “Learn more.” “See pricing” beats “Click here.”
Specific value props. “Cut CPA by 40%” beats “Improve performance.”
Ad copy testing. Most accounts run 1-2 ads per ad group for years. Running 4-6 responsive search ads (RSAs) gives the algorithm more material to optimize.
Sitelink and asset utilization. Sitelinks, callouts, structured snippets all expand your ad and increase CTR. Underused assets = underused CTR potential.
Avoid hyper-broad targeting. If your ads serve queries that are loosely related, CTR drops. Use negative keywords aggressively.
Realistic improvement: from Below Average → Average usually possible with copy refresh and asset additions. Above Average is rarer and tied to true relevance + brand strength.
Lever 2: Ad relevance
What it measures: how directly your ad copy addresses the keyword/query.
What moves it:
Keyword in the ad copy. Headlines and descriptions should include the target keyword (or close variants). Modern RSAs auto-pin themes; let the algorithm match.
Match ad copy to search intent. “Buy” keywords need “Shop now” copy. “Best” keywords need comparison copy. “How to” keywords need educational copy.
Don’t bundle unrelated keywords in one ad group. “Google Ads management” and “SEO services” together in one ad group means your ad can’t match both well.
Use single-theme ad groups. Each ad group should target 3-10 closely-related keyword variations, with ads that speak directly to that theme.
This is the cheapest fix in most accounts. Restructuring ad groups + writing relevant copy moves Ad Relevance to Above Average within weeks.
Lever 3: Landing page experience
What it measures: how well your landing page serves users from this keyword.
What Google evaluates:
Relevance to the keyword. Landing page content should match the search query’s intent. Sending all keywords to your homepage rarely works.
Page speed. Slow pages hurt landing page experience. Core Web Vitals matter — covered in our separate CWV article.
Mobile usability. Most clicks are mobile in 2026. Pages must work on mobile.
Easy navigation. Clear CTA, no dark patterns, no excessive ads or popups.
Original content. Thin or scraped content drops the score.
HTTPS. Mandatory baseline.
Transparency. Clear ownership, contact information, privacy policy.
This is often the biggest lever in mature accounts. Sending all keywords to a generic homepage caps Landing Page Experience at Average. Dedicated landing pages per campaign or major keyword theme push to Above Average.
A 30-day Quality Score improvement sprint
Days 1-5: Audit.
- Add Quality Score columns to your keywords view.
- Identify keywords with QS 1-5 (urgent improvement targets).
- For each, note which component (CTR, Relevance, Landing Page) is weakest.
Days 6-15: Ad relevance + structure.
- Restructure ad groups: each should target 3-10 tight thematic keywords.
- Write fresh ad copy with target keywords in headlines.
- Build 3-5 RSA variants per ad group.
- Verify Ad Relevance shifts upward over 7-14 days.
Days 16-25: CTR improvements.
- Add or expand sitelinks, callouts, structured snippets, image extensions.
- Test new headlines focused on specific value propositions.
- Add negative keywords to reduce noise.
Days 26-30: Landing page improvements.
- Identify keywords sending to mismatched landing pages.
- Build or repurpose dedicated landing pages for high-spend keywords.
- Implement basic Core Web Vitals fixes (image optimization, font loading).
Expected impact by day 60-90: average Quality Score lift of 1-3 points; CPC reduction of 15-30% on improved keywords.
Common Quality Score mistakes
1. Treating Quality Score as a single number. The 1-10 rollup is less actionable than the 3 components.
2. Sending everything to the homepage. Lazy landing page strategy caps your Quality Score.
3. One ad per ad group. Smart Bidding needs creative variety. RSAs are designed for multiple variations.
4. Ignoring Quality Score in Performance Max. PMax doesn’t report Quality Score the same way, but the underlying relevance signals matter. Strong asset groups and audience signals improve PMax’s equivalent of QS.
5. Optimizing only for Quality Score. It’s a means, not the end. A 10/10 keyword that doesn’t convert is worse than a 6/10 that does. Always tie improvements back to CPA/ROAS.
6. Not refreshing ads. Stale ad copy gradually loses CTR. Test new copy every 2-3 months.
Quality Score in modern broad-match world
Smart Bidding pushed broad match as the default. Broad match means more keyword variations, which complicates Quality Score interpretation.
What still applies:
- Tight keyword-to-ad theme alignment within ad groups
- Relevant landing pages
- Strong CTR-driving creative
What changed:
- Don’t obsess over per-keyword Quality Score with broad match — focus on ad group level performance
- Audience signals matter more (Customer Match, in-market, lookalikes)
- Smart Bidding lifts otherwise low-Quality-Score keywords if they convert well
The right mental model: Quality Score still affects CPC and Ad Rank, but Smart Bidding can route around it for high-conversion users. Don’t ignore Quality Score, but don’t worship it either.
Frequently asked questions
What’s a good average Quality Score? 7+/10 is solid. 8-9 is excellent. 10 is rare and usually tied to branded keywords. Below 5 needs attention.
Does Quality Score affect Performance Max? PMax doesn’t show Quality Score. But the underlying signals (relevance, asset quality, landing page experience) still influence PMax’s auction performance.
Can I improve Quality Score quickly? Ad Relevance changes in days. Expected CTR shifts in 1-2 weeks. Landing Page Experience shifts in 2-6 weeks. Full Quality Score improvements compound over 30-90 days.
Does Quality Score apply to display ads? Display has its own relevance scoring but doesn’t show “Quality Score” the same way. Apply similar principles (audience-creative match, landing page relevance).
Will Quality Score continue to exist? Google has signaled investment in moving from explicit Quality Score to internal relevance models. As of 2026, it’s still visible and still useful. Plan for it being deprioritized over time but still relevant in the medium term.
Quality Score isn’t dead — it’s still the cleanest single diagnostic of whether your account is structured well. A 30-day systematic improvement sprint delivers measurable CPC reduction and CPA improvement for almost every account that hasn’t done one recently. The work is unglamorous (ad copy iteration, ad group restructuring, landing page improvements), but the payback is immediate and lasting.
