Quality Score might be the most misunderstood metric in Google Ads. Advertisers obsess over it, yet most don't actually understand what it measures or how to improve it. Some chase a perfect 10 on every keyword while watching their actual results suffer. Others ignore it entirely and wonder why their CPCs keep climbing.
Here's the truth: Quality Score isn't a vanity metric. It directly affects how much you pay per click and whether your ads show at all. A keyword with a Quality Score of 10 can cost 50% less per click than the same keyword with a score of 5—for the exact same ad position. That's not a small difference. That's the difference between a profitable campaign and one that bleeds money.
This guide breaks down everything you need to know about Quality Score: what it actually measures, how Google calculates it, where to find it in your account, and most importantly—how to systematically improve it. No fluff, no outdated tactics, just what works in 2026.
What Is Google Ads Quality Score?#
Quality Score is Google's rating of the quality and relevance of your keywords, ads, and landing pages. It's measured on a scale of 1 to 10, with 10 being the highest. Each keyword in your account gets its own Quality Score based on historical performance data.
But here's what most people miss: the Quality Score you see in your account is a diagnostic tool, not the actual number Google uses in the ad auction. Google uses a real-time calculation called Ad Rank to determine your ad position and cost per click. Quality Score gives you visibility into the factors that influence Ad Rank, but the actual auction happens with more granular, real-time data.
Think of visible Quality Score as a health indicator. If your score is low, something is wrong with relevance or experience. If it's high, you're generally aligned with what Google (and searchers) expect. But don't mistake the diagnostic for the actual mechanism.
Why Quality Score Matters: The Real Impact on Your Campaigns#
Quality Score isn't just a number—it has direct financial consequences. Google rewards high-quality ads with lower costs and better positions. Here's exactly how it works.
Lower Cost Per Click
Google Ads uses a second-price auction modified by Quality Score. You don't pay your maximum bid—you pay just enough to beat the Ad Rank of the advertiser below you. Higher Quality Scores mean you need to bid less to achieve the same Ad Rank.
The math works like this: Ad Rank = Bid x Quality Score (simplified). If your competitor bids $5 with a Quality Score of 6, their Ad Rank is 30. You could match that Ad Rank by bidding $3 with a Quality Score of 10, or $4.29 with a Quality Score of 7. Higher quality literally costs less.
We've seen accounts reduce their average CPC by 30-40% simply by improving Quality Scores from below average to above average—without changing bids at all. That's pure profit straight to the bottom line.
Better Ad Positions
With equivalent bids, higher Quality Scores win higher positions. This matters because top positions get dramatically more clicks. Position 1 might get 30%+ of clicks, while position 4 gets single digits. Quality Score is your lever for earning those premium positions without overpaying.
Access to Ad Extensions and Formats
Google only shows ad extensions (sitelinks, callouts, structured snippets) when your Ad Rank exceeds certain thresholds. Low Quality Scores can prevent your extensions from showing entirely, even if you've set them up perfectly. You're leaving clicks on the table.
Eligibility for Ad Auctions
If your Quality Score is too low, your ads might not show at all for certain searches. Google sets minimum Ad Rank thresholds, and if your combination of bid and quality doesn't meet them, you're excluded from the auction. This is especially common on competitive keywords where low-quality advertisers get filtered out.
The Three Components of Quality Score#
Quality Score breaks down into three distinct factors, each measured as 'Above Average,' 'Average,' or 'Below Average.' Understanding each component lets you diagnose problems and prioritize fixes.
1. Expected Click-Through Rate (CTR)
Expected CTR predicts how likely your ad is to be clicked when shown. Google calculates this based on historical performance of your keyword, normalized for position and other factors. It answers the question: when people see your ad for this keyword, do they click?
This is often the most impactful component because it reflects ad quality most directly. A 'Below Average' expected CTR usually means your ad copy doesn't resonate with the search intent, or your offer isn't compelling enough to earn the click.
Important nuance: Google compares your expected CTR to other advertisers on the same keyword, not to your account average or industry benchmarks. A 3% CTR might be great for one keyword and terrible for another, depending on competition.
- Above Average: Your ads get clicked more often than competitors for this keyword—keep doing what you're doing
- Average: You're in line with competitors—room for improvement but not urgent
- Below Average: Your ads significantly underperform competitors—prioritize ad copy testing immediately
2. Ad Relevance
Ad relevance measures how closely your ad copy matches the intent behind the keyword. It's about alignment between what someone searches and what your ad promises. If someone searches 'emergency plumber near me' and your ad talks about bathroom remodeling, that's a relevance mismatch.
This component is usually the easiest to fix because it's largely about structure. Include keywords in your ad headlines. Make sure your ad groups are tightly themed. Write ads that speak directly to the search query.
A 'Below Average' ad relevance score often indicates one of two problems: either your ad groups contain too many loosely related keywords, or your ad copy is too generic and doesn't address specific search intents.
- Above Average: Your ads directly address the searcher's query—excellent alignment
- Average: Reasonable match but not perfectly tailored—consider tighter ad groups
- Below Average: Significant mismatch between keyword and ad copy—restructure immediately
3. Landing Page Experience
Landing page experience evaluates how useful and relevant your landing page is to people who click your ad. Google considers content relevance, page load speed, mobile-friendliness, navigation ease, and transparency about your business.
This component often gets overlooked because it requires website changes, not just account changes. But landing page experience increasingly matters as Google emphasizes user experience across all its products. A slow, confusing, or irrelevant landing page drags down your entire Quality Score.
Google's crawlers evaluate your landing pages, so the assessment happens even without significant click volume. They're checking: Does the page deliver on the ad's promise? Can users easily find what they need? Does the page load quickly on all devices?
- Above Average: Your landing page provides excellent experience—fast, relevant, and user-friendly
- Average: Acceptable experience but room for improvement—audit for quick wins
- Below Average: Significant problems with relevance, speed, or usability—fix before scaling spend
How to Check Your Quality Score#
Quality Score isn't visible by default in Google Ads. You need to add the columns to see it. Here's exactly how to access this data.
Adding Quality Score Columns
- 1Sign in to your Google Ads account and navigate to the Keywords section
- 2Click the columns icon (looks like three vertical lines) above your data table
- 3Select 'Modify columns' from the dropdown menu
- 4Expand the 'Quality Score' section in the column list
- 5Add: Quality Score, Exp. CTR, Ad Relevance, Landing Page Exp., and optionally the historical versions
- 6Click 'Apply' to save your column configuration
You'll now see Quality Score data for each keyword. Note that keywords need sufficient impression history before Google calculates a score—brand new keywords may show '--' until they accumulate data.
Understanding Historical Quality Score
Google also provides historical Quality Score columns (Quality Score (hist), Exp. CTR (hist), etc.) that show how your scores have changed over time. This is valuable for tracking the impact of your optimization efforts. If you made changes last month, historical data shows whether scores improved.
Set your date range to a specific period, and historical columns will show the Quality Score during that time. This helps you correlate score changes with specific actions you took.
How to Improve Expected Click-Through Rate#
Expected CTR is often the most impactful lever for Quality Score improvement. Here are proven strategies to boost your click-through rates.
Write Compelling Headlines
Your headlines are the most visible part of your ad. They need to grab attention, match search intent, and differentiate you from competitors. Generic headlines like 'Quality Products - Shop Now' won't cut it.
- Include the keyword or close variation in Headline 1—this shows immediate relevance
- Lead with benefits, not features—'Save 40% on Energy Bills' beats 'High-Efficiency Windows'
- Use numbers and specifics—'47,000+ 5-Star Reviews' is more clickable than 'Great Reviews'
- Create urgency when appropriate—'Limited Time: Free Installation' drives action
- Test questions that resonate with pain points—'Still Paying Too Much for Insurance?'
Leverage All Available Ad Real Estate
Google allows multiple headlines and descriptions. Use them all. More ad copy means more chances to include relevant keywords, more space to communicate value, and larger visual presence on the search results page.
For Responsive Search Ads, provide the maximum 15 headlines and 4 descriptions. Google will test combinations and surface the best performers. Pin your most important messages to ensure they always show, but leave room for Google's testing.
Use Ad Extensions Strategically
Extensions make your ad bigger and more useful, which improves CTR. At minimum, every campaign should have sitelinks, callouts, and structured snippets. For local businesses, add location extensions. For promotions, add promotion extensions.
- Sitelinks: Direct users to specific pages—pricing, features, testimonials, contact
- Callouts: Highlight benefits—'Free Shipping', '24/7 Support', 'No Contracts'
- Structured Snippets: List offerings—services, brands, types, destinations
- Call Extensions: Let mobile users call directly—huge for local businesses
- Image Extensions: Add visual elements that catch the eye in search results
Test Continuously
CTR improvement is iterative. Create ad variations with different angles, benefits, and formats. Let data determine winners. A headline that seems clever in your head might flop with actual searchers, while a straightforward benefit statement outperforms everything.
Run experiments for at least 2-4 weeks or until you have statistical significance. Don't judge too quickly—early data can be misleading. Once you identify winners, iterate on them rather than starting from scratch.
How to Improve Ad Relevance#
Ad relevance is fundamentally about structure and alignment. The goal is ensuring your ads speak directly to the keywords that trigger them.
Tighten Your Ad Group Themes
The single biggest cause of poor ad relevance is ad groups that contain too many unrelated keywords. If one ad group has 'running shoes,' 'marathon training,' and 'athletic apparel,' no single ad can be perfectly relevant to all three intents.
Aim for 10-20 closely related keywords per ad group, all unified by a single theme that one ad can address. Some advertisers go even tighter with Single Keyword Ad Groups (SKAGs) for their most important terms, though this creates management overhead.
- Group keywords by intent, not just topic—'buy running shoes' and 'running shoe reviews' are different intents
- Create separate ad groups for different product categories, services, or audience segments
- When in doubt, split—it's easier to consolidate later than to untangle poor structure
Include Keywords in Ad Copy
This sounds obvious, but many advertisers write generic ads that could apply to any product. Your ad copy should include the keywords or close variations. When someone searches 'emergency plumber san diego,' they should see those words (or synonyms) in your ad.
Use keyword insertion ({KeyWord:Default}) strategically to automatically include the searched keyword in your ad. But don't over-rely on it—keyword insertion can create awkward copy if not managed carefully.
Match Ad Messaging to Search Intent
Relevance goes beyond keyword matching. Your ad needs to address what the searcher actually wants. Someone searching 'best CRM for small business' wants comparison information, not a hard sell. Someone searching 'CRM free trial' is ready to act and wants a clear path to sign up.
Study the search terms report to understand how people actually search. Write ads that speak to those specific needs, not just your preferred messaging.
How to Improve Landing Page Experience#
Landing page experience often requires website changes, but the impact on Quality Score and conversion rates makes it worthwhile. Here's what to optimize.
Ensure Content Relevance
The landing page must deliver on your ad's promise. If your ad mentions '50% off winter jackets,' the landing page better show winter jackets at 50% off—above the fold, immediately visible. Bait-and-switch destroys both Quality Score and conversion rates.
- Match headlines between ad and landing page—consistency builds trust
- Feature the promoted product, service, or offer prominently
- Address the search intent directly—if they searched for pricing, show pricing
- Include the target keywords naturally in page content
Optimize Page Speed
Slow pages kill Quality Score and conversions. Google explicitly factors load time into landing page experience. Every second of delay increases bounce rates and signals poor user experience.
Prioritize Mobile Experience
Most Google searches happen on mobile devices. Your landing page must work flawlessly on phones—fast loading, easy navigation, readable text without zooming, and tap-friendly buttons. Test on actual devices, not just browser simulations.
- Use responsive design that adapts to all screen sizes
- Make CTAs large enough to tap easily (minimum 44x44 pixels)
- Avoid popups that cover mobile screens—Google penalizes intrusive interstitials
- Simplify forms for mobile entry—fewer fields, larger inputs, autofill support
Build Trust and Transparency
Google evaluates whether your landing page is trustworthy. This includes clear business information, visible contact details, privacy policies, and secure connections (HTTPS). Sketchy-looking pages get penalized even if content is relevant.
- Display clear contact information—phone, email, physical address if applicable
- Show trust signals—security badges, reviews, testimonials, certifications
- Use HTTPS across your entire site—this is non-negotiable in 2026
- Be transparent about pricing, shipping, and policies
Quality Score Optimization Strategy: A Systematic Approach#
Improving Quality Score requires systematic effort, not random tweaking. Here's the approach we use at MBell Media to drive consistent improvements.
Step 1: Audit Current State
Export your keyword data including Quality Score and its three components. Identify patterns: Are most 'Below Average' ratings in CTR, relevance, or landing page? Are certain campaigns or ad groups consistently low? This diagnosis determines where to focus.
Step 2: Prioritize High-Impact Keywords
Not all keywords deserve equal attention. Focus optimization efforts on keywords that combine low Quality Score with high volume or strategic importance. A Quality Score improvement on a keyword getting 10,000 impressions/month matters more than one getting 100.
Step 3: Fix Structural Issues First
If ad relevance is 'Below Average' across many keywords, you likely have a structure problem. Restructure campaigns and ad groups before testing new ad copy. No amount of copywriting can fix a keyword sitting in the wrong ad group.
Step 4: Test and Iterate
Create new ad variations targeting the specific component that's lagging. If CTR is the issue, test new headlines. If landing page experience is low, test different landing pages. Run tests with sufficient budget and time to reach conclusions.
Step 5: Monitor and Maintain
Quality Score isn't a set-it-and-forget-it metric. Competitor actions, seasonal changes, and platform updates can shift scores over time. Review Quality Scores monthly and address any deterioration quickly before it impacts performance.
Common Quality Score Myths Debunked#
Misinformation about Quality Score is rampant. Let's clear up the most common misconceptions.
Myth: You Need a Quality Score of 10 on Every Keyword
Reality: A 7-8 is often perfectly healthy, especially for competitive keywords. Chasing a perfect 10 can lead to over-optimization at the expense of other priorities. Focus on improving 'Below Average' components rather than perfecting already-good scores.
Myth: Quality Score Updates Instantly
Reality: Visible Quality Score updates periodically based on accumulated data. You might make changes and not see score movement for days or weeks. The real-time auction uses fresher signals than the diagnostic score you see in the interface.
Myth: Display and Search Quality Scores Work the Same
Reality: Search Quality Score (what this guide covers) is different from how Google evaluates Display and Video campaigns. Display uses different relevance signals focused on audience and placement fit rather than keyword-ad alignment.
Myth: Pausing Keywords Resets Quality Score
Reality: Quality Score history persists even when keywords are paused. Pausing a low-QS keyword and reactivating it won't magically reset the score. You need to actually fix the underlying issues.
Quality Score and Smart Bidding: How They Interact#
With the rise of automated bidding strategies, some advertisers wonder if Quality Score still matters. The answer is absolutely yes—but the relationship is nuanced.
Smart Bidding strategies like Target CPA and Target ROAS still compete in auctions where Quality Score affects Ad Rank and actual CPCs. Higher Quality Scores mean the algorithm can achieve your targets more efficiently. The bidding is automated, but the quality signals still drive costs.
Think of it this way: Smart Bidding optimizes your bids, but Quality Score determines how much value those bids generate. Two advertisers with identical Smart Bidding targets will achieve different results if one has significantly better Quality Scores.
Quality Score by Campaign Type#
Quality Score applies differently depending on your campaign type. Here's what to understand for each.
Search Campaigns
This is where Quality Score matters most and is most visible. Every keyword has a Quality Score that directly impacts auction dynamics. Optimization efforts here yield the clearest, most measurable results.
Performance Max Campaigns
Performance Max doesn't show traditional Quality Scores because it doesn't use traditional keywords. However, Google still evaluates asset quality internally. Provide strong creative assets, relevant landing pages, and clear audience signals to help the algorithm perform.
Shopping Campaigns
Shopping doesn't use Quality Score in the same way. Product relevance comes from your feed data and how well it matches search queries. Focus on feed optimization—titles, descriptions, images, and attributes—rather than traditional QS factors.
Tracking Quality Score Impact: Metrics That Matter#
Quality Score improvements should translate to measurable business outcomes. Track these metrics to confirm your efforts are paying off.
- Average CPC: Should decrease as Quality Scores improve, all else equal
- Impression Share: Higher quality earns more auction wins
- Click-Through Rate: Direct input to Quality Score and validation of ad improvements
- Cost Per Conversion: The ultimate measure—better quality should mean more efficient conversions
- Average Position (via Impression metrics): Better quality earns better placement
Build a dashboard tracking Quality Score distributions alongside these performance metrics. When QS improves but performance doesn't, dig deeper—something else might be broken. When both improve together, you've found a genuine optimization.
When Quality Score Isn't the Problem#
Sometimes advertisers blame Quality Score when the real issue lies elsewhere. Quality Score won't save you if:
- Your offer isn't competitive—no amount of ad optimization fixes a weak value proposition
- You're targeting wrong keywords—high QS on irrelevant terms still wastes money
- Your conversion tracking is broken—you can't optimize what you can't measure
- Budget is too limited—some keywords need significant spend to compete regardless of quality
- Market dynamics shifted—what worked last year might not work today
Quality Score Quick Wins: Start Here#
If you want immediate improvements, focus on these high-impact actions first:
- 1Add Quality Score columns to your keyword view if you haven't already
- 2Identify your highest-volume keywords with Quality Score below 6—these are priority fixes
- 3Check for 'Below Average' ad relevance—this usually means restructuring ad groups
- 4Review landing pages for your worst-performing keywords—ensure content matches ad promise
- 5Test new ad copy variations for keywords with 'Below Average' expected CTR
- 6Add missing ad extensions—sitelinks, callouts, and structured snippets at minimum
Conclusion: Quality Score as Competitive Advantage#
Quality Score isn't just about saving money on clicks—though that alone makes it worth optimizing. It's about building a sustainable competitive advantage in paid search. Advertisers who consistently earn high Quality Scores can outbid competitors while paying less, show in more auctions, and access premium ad formats that others can't.
The advertisers who win on Google Ads aren't always those with the biggest budgets. They're the ones who understand that relevance and experience matter as much as dollars. Quality Score is Google's way of rewarding that understanding.
Start with the foundations: tight ad group structure, compelling ad copy, and relevant landing pages. Measure the three components separately and address weak spots systematically. Monitor over time and adapt as conditions change. Do this consistently, and you'll build Quality Scores that translate to lower costs and better results.
