Quality Score is Google’s 1-to-10 rating of how relevant your keywords, ads, and landing pages are to the person searching. It’s built from three components: expected click-through rate, ad relevance, and landing page experience. A higher score generally means lower costs per click and better ad positions. A lower score means you’re paying a premium for the same traffic your competitors get cheaper.
At Gorilla Marketing, we manage Google Ads campaigns where Quality Score optimization is part of the work from day one, not an afterthought. This guide breaks down what Quality Score actually measures, what it doesn’t, where to find it, and how to improve the specific components that will make the biggest difference to your account performance.
What Is Quality Score, Exactly?
Quality Score is a diagnostic metric Google assigns to each keyword in your Search campaigns. It’s reported on a scale of 1 to 10, with 10 being the best. Google calculates it based on three factors:
Expected click-through rate (CTR) – how likely users are to click your ad for this keyword, relative to other advertisers
Ad relevance – how closely your ad copy matches the intent behind the search query
Landing page experience – how useful, relevant, and easy to navigate your landing page is for someone who clicks
Each component gets a rating of “Below Average,” “Average,” or “Above Average” based on how you compare against other advertisers who’ve shown ads for the same keyword over the past 90 days. The overall 1-to-10 number is a combined estimate from those three signals.
Here’s what matters: Quality Score is a diagnostic tool. Google has been explicit about this. It tells you where your ads might have problems, but it is not directly used in the ad auction. The actual auction uses real-time quality calculations that factor in the same signals but also account for the user’s device, location, time of day, search terms, and other context that a static 1-to-10 number can’t capture.
Think of it like a check engine light. It tells you something needs attention. It doesn’t tell the engine how to run.
Quality Score vs. Ad Rank: The Distinction That Matters
Most guides conflate these two things. They shouldn’t.
Ad Rank determines whether your ad shows and in what position. It’s calculated at auction time using your bid, your ad quality (a real-time assessment), the competitiveness of the auction, the context of the search, and the expected impact of ad extensions and other ad formats.
Quality Score is a simplified, backward-looking summary of your ad quality components. It’s updated periodically, not in real time. It doesn’t factor in device, location, or the specific search query the way Ad Rank does.
The practical implication: you can have a Quality Score of 8 and still lose auctions to someone with a 6, because their real-time quality signals and bid combination beat yours for that specific search. And you can have a Quality Score of 5 and win auctions where context works in your favor.
Quality Score is useful for spotting problems. It’s not a leaderboard position.
Where to Find Quality Score in Your Account
Quality Score isn’t visible by default in Google Ads. Go to your Keywords tab, click Columns, then Modify columns, and add Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience from the Quality Score section. You can also add historical columns to track changes over time.
Keywords need a minimum volume of impressions before Google assigns a score. New or very low-volume terms may show blank until enough data accumulates. That’s normal, not a red flag.
How Quality Score Affects Your Costs
While Quality Score itself isn’t used in the auction, the underlying quality signals it reflects absolutely are. Higher ad quality means Google needs less money from you to show your ad in a given position. Lower ad quality means you pay more.
The math works like this in simplified terms: your actual CPC is influenced by the Ad Rank of the advertiser below you, divided by your own quality. Two advertisers bidding the same amount for the same keyword can pay very different CPCs purely because of quality differences.
Over a large account, this compounds fast. If you’re running $50,000 a month through Google Ads and your quality signals are consistently weak, you could be paying 20-30% more per click than an advertiser with stronger relevance and landing page experience. That’s real money walking out the door every month, not because your bids are wrong, but because your quality signals are.
What Does a “Good” Quality Score Look Like?
Here’s the honest answer most guides won’t give you: a Quality Score of 7 is good enough for most keywords.
Chasing 10/10 on every keyword is a misallocation of effort. Brand keywords will naturally score 8-10 because you’re the most relevant result for your own name. Generic, high-competition keywords often sit at 5-7 even for well-optimized accounts because everyone is competing for the same terms with similar ads and pages.
A practical framework:
| Score | What It Usually Means | Action |
|---|---|---|
| 1-3 | Serious mismatch between keyword, ad, and landing page | Fix immediately or pause |
| 4-5 | Below average on at least one component | Diagnose and optimize |
| 6 | Acceptable but room for improvement | Optimize if high-spend keyword |
| 7 | Good. Competitive with most advertisers | Monitor, don’t obsess |
| 8-10 | Strong. Typically brand terms or tight ad groups | Maintain |
The keywords worth your optimization time are the ones where (a) Quality Score is below 6 AND (b) the keyword drives meaningful spend or conversions. A keyword with a Quality Score of 4 that gets 10 clicks a month isn’t worth hours of work. A keyword with a Quality Score of 5 that drives $8,000 in monthly spend is worth immediate attention.
Diagnosing Quality Score Problems: A Component-by-Component Approach
The 1-to-10 number is nearly useless for optimization on its own. You need to look at which component is dragging the score down. Each one points to a different fix.
When Expected CTR Is Below Average
This means Google predicts users are less likely to click your ad than competitors’ ads for the same keyword. The problem is almost always in your ad copy.
Check these first:
Does your headline include the keyword or a close variation? Users scan for relevance before they read.
Is your value proposition clear in the first two headline slots? Don’t bury the benefit.
Are you using all available ad assets (sitelinks, callouts, structured snippets)? Ads with more real estate get more clicks.
How does your ad compare visually to competitors? Search for the keyword and look at what’s showing. If everyone else has a stronger offer or clearer messaging, your CTR will suffer.
Expected CTR is normalized for ad position, so you’re not being penalized just for showing in position 4 instead of position 1. Google adjusts for the natural CTR differences between positions.
When Ad Relevance Is Below Average
This means Google doesn’t see a strong connection between your keyword and your ad copy. The keyword is triggering ads that don’t feel like a direct answer to what the user searched.
Check these first:
Is the keyword actually in your ad text? Not buried in description line 2, but prominently in a headline.
Is the ad group too broad? If you’ve got 30 keywords in one ad group with two generic ads, most of those keywords won’t match the ad well. Tighter ad groups with fewer, closely related keywords solve this.
Does the ad address the specific intent behind the keyword? “Affordable CRM software” and “enterprise CRM platform” need different ads even though they’re both about CRM.
Ad relevance is often the fastest component to fix. Reorganizing ad groups and rewriting ad copy to match keyword themes can move this from Below Average to Average within a few weeks of data collection.
When Landing Page Experience Is Below Average
This means the page users land on after clicking doesn’t meet Google’s standards for relevance, usefulness, or usability. This is the component that takes the longest to fix because it involves changes to your website, not just your ad account.
Check these first:
Does the landing page content match what the ad promises? If your ad says “free trial” and the landing page leads with pricing, that’s a mismatch.
Is the page mobile-friendly? Google evaluates mobile experience heavily.
How fast does the page load? Slow pages hurt landing page experience scores. Run it through PageSpeed Insights.
Is the content original and substantive? Thin pages with minimal content or duplicate content from other pages on your site will score poorly.
Can users easily find what they need? Clear navigation, visible CTAs, and logical page structure all factor in.
Landing page experience is also where your broader SEO and UX work directly benefits your paid campaigns. A well-built, fast, relevant landing page improves Quality Score, conversion rates, and organic rankings simultaneously.
The Diagnostic Flowchart
When a keyword’s Quality Score drops or stays stubbornly low, work through this sequence:
Step 1: Check which component is Below Average. If more than one, start with ad relevance (fastest to fix).
Step 2: If ad relevance is the issue – look at your ad group structure. Does the keyword belong in a tighter group? Does the ad copy reference the keyword or its intent? Restructure the ad group or write new ads that match the keyword theme more tightly.
Step 3: If expected CTR is the issue – compare your ad copy against competitors. Is your offer compelling? Are your headlines specific or vague? Test new headlines with stronger value propositions. Make sure you’re using all available ad assets.
Step 4: If landing page experience is the issue – check page speed, mobile usability, and content relevance. Does the page deliver on the ad’s promise? Is there enough content to satisfy the query? Are there technical issues (slow load, broken elements, intrusive popups)?
Step 5: Give it time. Quality Score updates aren’t instant. Allow 2-4 weeks of impression data before judging whether the fix worked. Isolate variables so you know what moved the needle.
Step 6: If all three components are Below Average – the keyword, ad, and page combination is fundamentally misaligned. Sometimes the right move is to pause it and redirect budget to keywords where the match is stronger.
Quality Score Myths That Won’t Die
“Quality Score directly determines your CPC”
Not exactly. The underlying quality signals influence your CPC through Ad Rank calculations, but Quality Score itself (the 1-to-10 number you see in your account) isn’t plugged into the auction formula. It’s a simplified summary of the signals that are. Improving the components that make up Quality Score will generally lower your costs, but the relationship isn’t as direct as “raise QS by 2 points, save 20%.”
“Pausing a keyword resets its Quality Score”
It doesn’t. Quality Score is tied to historical performance data. Pausing and reactivating a keyword brings back the same score. If you want a fresh start, you’d need to delete the keyword and re-add it, but even then, account-level historical performance still influences initial scoring.
“You need a Quality Score of 10 to compete”
Rarely. A 10 is typical for brand keywords and very little else. For competitive generic terms, scores of 6-8 are normal across strong accounts. Chasing 10/10 usually means over-segmenting ad groups to the point where you lose volume and create management overhead that doesn’t justify the incremental savings.
“Quality Score applies to all campaign types”
It doesn’t. Quality Score as a visible, reportable metric applies to Search campaigns only. Display, Video, Shopping, and Performance Max campaigns don’t surface a Quality Score number. Those campaign types have their own quality signals, but they’re not exposed in the same way.
“Higher bids improve Quality Score”
Bids have no impact on Quality Score. Google has stated this explicitly. Expected CTR calculations are normalized for ad position, so bidding more to get a higher position won’t artificially inflate your CTR component. Quality Score is about relevance and experience, not how much you’re willing to pay.
“Match type affects Quality Score”
Quality Score is calculated at the keyword level using exact-match behavior, regardless of the match type you’ve set. Whether your keyword is broad match, phrase match, or exact match, the Quality Score reflects performance as if the keyword were exact match. Your match type setting doesn’t influence the score.
Quality Score and Performance Max
If you’re running Performance Max campaigns, you won’t see a Quality Score column. PMAX doesn’t use the same keyword-based auction mechanics as Search campaigns. It’s an automated, cross-channel campaign type where Google’s machine learning handles targeting, bidding, and creative combination across Search, Display, YouTube, Discover, Gmail, and Maps.
That doesn’t mean quality doesn’t matter in PMAX. Google still evaluates ad quality signals internally. The assets you provide and the landing pages you point to still affect how often and where your ads show. But you don’t get a numeric score to optimize against.
If you’re shifting budget from Search to PMAX, you lose the diagnostic visibility that Quality Score provides. Your levers become asset quality, landing page performance, and audience signals. For accounts that rely heavily on PMAX, monitoring conversion rates, CPA, and ROAS becomes even more important because Quality Score can’t serve as an early warning system.
Account-Level Quality Score: The Invisible Factor
Google doesn’t officially acknowledge an account-level Quality Score, but practitioner experience and Google’s own patents suggest historical account performance influences how new keywords and campaigns are scored initially. Launch a new campaign in an account with strong history and your keywords tend to start with reasonable scores. Launch the same campaign in a poor-performing account and they don’t.
The implication: don’t pollute your account with keywords you know will perform poorly. Pause or remove underperformers quickly rather than letting them accumulate bad data that drags down your aggregate history.
Where to Focus First (and Where Not to Bother)
If you’re looking at an account with mixed Quality Scores and limited time, prioritize by spend and impact. Fix your ad group structure first. It’s the single highest-impact move. Most Quality Score problems trace back to ad groups that are too broad, with too many loosely related keywords sharing the same generic ad copy. Tighter thematic groups fix ad relevance and expected CTR simultaneously.
After structure, align landing pages with ad promises. If your ad mentions a specific feature, the landing page should lead with that feature. Generic pages that try to serve every ad in the account will drag landing page experience scores down. And use negative keywords aggressively. They don’t directly affect Quality Score, but they prevent irrelevant searches from triggering your ads, which protects your CTR.
There are also scenarios where obsessing over Quality Score is the wrong move. Low-volume keywords (50 impressions a month) don’t have enough data for the score to mean much. Brand keywords almost always sit at 8-10 with no optimization needed. And sometimes a keyword converts well despite a Quality Score of 4 or 5. If the ROI is strong, don’t kill a profitable keyword just because a diagnostic metric says it’s below average. Profitability is the ultimate metric, not Quality Score.
One more consideration: if you’re running Smart Bidding strategies (Target CPA, Target ROAS, Maximize Conversions), Google’s algorithm already factors in quality signals at auction time and compensates through bid adjustments. Quality Score still helps you spot problems, but your optimization energy may be better spent on conversion tracking, audience strategy, and creative testing.
Making Quality Score Work for You
Quality Score is one of the most misunderstood metrics in Google Ads. It’s not a grade on your campaign. It’s not used directly in auctions. And it’s definitely not something to chase to 10/10 across the board. But the signals it reflects – ad relevance, expected CTR, and landing page experience – are the same signals that determine what you pay and where you show.
Treat it as a diagnostic tool. When scores drop, investigate. When a high-spend keyword sits at 4 or 5, fix the component that’s dragging it down. When scores are 7 or above, move on to something that will have a bigger impact on your bottom line.
And if you’re looking at an account where Quality Scores are consistently low, ad costs keep climbing, and you’re not sure where to start, talk to our Google Ads team. We’ll run a diagnostic on your account structure, ad relevance, and landing page alignment to find the specific fixes that will lower your costs and improve your results.
