If you’ve spent any time managing Google Ads campaigns, you’re probably aware that two advertisers can bid on the very same keyword yet pay wildly different amounts per click. That’s by design. It just means that Google Ads’ Quality Score is doing its job.
Google Ads’ Quality Score grades how relevant and useful your ads are to the people searching for keywords you’re bidding on. It can affect your pay-per-click (PPC) costs and the frequency of your ad appearing in search results. A high Quality Score equals paying less for better placement; a low one, on the other hand, means that you’re overpaying for worse results.
At the core of that score lies ad relevance. When your ads align tightly with users’ search intent, everything improves: your Quality Score goes up, your costs go down, and your ads reach the right people.
So let’s break down exactly how all of this works, and what you can do to improve both your Quality Score and Ad Relevance.
What Is Google Ads’ Quality Score?
Google Ads’ Quality Score is a diagnostic rating from 1 to 10 assigned at the keyword level. It informs you how your ad experience compares to that of other advertisers competing for the same keyword. A score of 1 means you’re doing something wrong. A 10, on the other hand, suggests that you’re outperforming most of the competition on the factors Google cares about.
Three components make up your Quality Score:
- Expected click-through rate (CTR): The likelihood of a user clicking on your ad when it appears for the keyword they’re searching for. All of this revolves around historical performance; it isn’t your actual CTR. It’s a prediction, normalized to account for ad position and other factors.
- Ad relevance: How closely your ad copy matches the intent behind the keyword being searched. For example, if someone searches “emergency plumber near me” and your ad talks about general home renovation, that right there is a relevance mismatch.
- Landing page experience: Google evaluates whether your landing page aligns with the ad’s promise, loads quickly, and is easy to use on any device.
Each of these three components gets rated as either “Below Average,” “Average,” or “Above Average.” The combination of those ratings produces your 1–10 score.
How Google Actually Calculates Quality Score
Here’s where things get a bit tricky. The Quality Score you see in Google Ads is not the same as the one Google uses in real-time auctions.
During each auction, Google calculates a more granular, real-time version of the Quality Score. This auction-time assessment factors in things like the users’ devices, location, time of day, and other contextual details that the generic 1–10 score simply can’t capture.
So while the Quality Score you see in Google Ads is useful for diagnostics and trend-spotting, the actual auction math is way more dynamic.
Why Quality Score Affects Your Costs
How does this affect what you pay?
Google Ads doesn’t just hand the top position over to the highest bidder. Your Ad Rank, which determines both your position in search results and your actual CPC, is calculated based on your bid and Quality Score (along with other factors, such as ad extensions and auction context). If you want to learn more about how Ad Rank works, we’ve covered that in detail in our guide to Ad Position and Ad Rank.
To sum things up, a higher Quality Score means you can achieve the same Ad Rank with a lower bid. Google rewards advertisers who create relevant, useful ad experiences by charging them less per click. On the flip side, a low Quality Score forces you to bid more aggressively just to compete; this is why the Quality Score isn’t just some vanity metric.
Quality Score directly impacts your budget efficiency and how far your ad spend goes. Two advertisers targeting the same keyword with the same bid can end up paying very different CPCs, and Quality Score is usually the reason.
How to Check Your Quality Score
The Quality Score isn’t visible by default in Google Ads, but it’s easy to find. In your Google Ads account, under “Campaigns,” click on the “Audiences, keywords, and content” tab and then again on Keywords. Click the columns icon (three vertical lines), and the “Modify Columns for keywords” section will pop up. Under the “Quality Score” section, you’ll find options to add Quality Score, along with its three components: Expected CTR, Ad Relevance, and Landing Page Experience. You can also add the historical versions of each metric to see how they’ve changed over time.
Once you’ve added those columns, you can sort and filter your keyword list to quickly spot which keywords have low scores, and which component drags them down. That tells you where to focus your optimization efforts.
What Is Ad Relevance in Google Ads?
Ad relevance is one of the three components of Quality Score, and it measures how well your ad copy aligns with the intent behind a given keyword. Google evaluates this by looking at the relationship between the keyword that triggered your ad and the ad’s language, messaging, and focus.
You’ll see ad relevance reported as one of three statuses in your Google Ads account: “Below Average,” “Average,” or “Above Average.” There’s no numeric score for this component alone; there are just those three labels.
How Google Evaluates Ad Relevance
To evaluate Ad Relevance, Google isn’t just doing a simple keyword-match check. It’s looking at whether your ad meaningfully addresses what the searcher is trying to accomplish. A few things factor into that evaluation:
- Keyword-to-ad copy alignment is the most straightforward one. Let’s say your keyword is “custom kitchen cabinets” and your ad headline says “Custom Kitchen Cabinets – Built to Your Specs”; that’s strong alignment. If your headline says “Home Improvement Services”, that’s vague enough to hurt your relevance rating.
- Search intent matching goes a step further. Here, Google is evaluating whether your ad addresses the type of need behind the search. Someone searching “best CRM for small business” is in research mode. Someone searching “buy Salesforce subscription” is ready to purchase. Your ad needs to match not just the words, but also the intent.
- Ad group structure plays a bigger role here than most people realize. If you’ve crammed dozens of loosely related keywords into a single ad group, your ad copy can’t be relevant to all of them. Tight ad groups with closely themed keywords make it much easier to write ads that score well on relevance. We’ll get into the specifics of how to structure this in the optimization section below.
The Relationship Between Quality Score and Ad Relevance
Ad relevance doesn’t just influence Quality Score; it’s one of its most actionable levers. Expected CTR is partly a function of historical performance you can’t fully control, and landing page experience involves your whole web development workflow. But ad relevance? That’s something you can improve this afternoon by restructuring your ad groups and rewriting your copy.
When your ad relevance improves, two things tend to happen in sequence. First, your Quality Score goes up because one of its three components just got better. Second, your expected CTR usually improves too, because more relevant ads naturally attract more clicks.
What This Looks Like in Practice
Let’s walk through a realistic example. Say you’re a dental practice running Google Ads, and you have one ad group with the following keywords: “teeth whitening,” “dental implants,” “emergency dentist,” and “dental cleaning near me.” Your single ad tries to cover all of these:
Headline 1: Quality Dental Care
Headline 2: Book an Appointment Today
Description: We offer a full range of dental services for the whole family. Call now.
That ad is so generic it’s barely relevant to any of those keywords. Google sees “teeth whitening” trigger an ad about “quality dental care” and rates the relevance as Below Average. Your Quality Score sits at 4, and your CPC for “teeth whitening” is $6.50.
Now, you break those keywords into separate, tightly themed ad groups. The “teeth whitening” ad group gets its own dedicated ad:
Headline 1: Professional Teeth Whitening
Headline 2: Brighter Smile in One Visit
Description: In-office and take-home whitening options. See results fast. Book your appointment today.
That ad directly addresses the keyword and the intent behind it. Ad relevance jumps to Above Average. Quality Score climbs to 8. Your CPC drops to $3.80 for the same keyword, and your CTR goes up because the ad actually speaks to what people are searching for.
That’s not a hypothetical stretch. Those kinds of improvements are common when campaigns move from broad, catch-all ad groups to tightly structured ones with dedicated ad copy that matches the keyword intent.
Landing Page Relevance and Its Role in Quality Score
Landing page experience is the third pillar of Quality Score, and it extends beyond your Google Ads account into your website. Google evaluates landing pages on three main criteria: relevance, usability, and transparency.
- Relevance means the content on your landing page matches the promise your ad made. If your ad promotes “affordable teeth whitening in Birmingham” and the click sends someone to your general homepage, that’s a mismatch. The page should directly address the topic the user searched for.
- Usability covers factors such as page speed, mobile-friendliness, and how easy it is to find the information a user is looking for. A slow page that takes four seconds to load on mobile is going to hurt your landing page experience score, and your conversion rate, for that matter.
- Transparency is about trust. Google wants to see that your landing page clearly explains what your business is about, how you handle customer information, and what a visitor can expect. Hidden fees, misleading claims, or a missing privacy policy can all work against you here.
The Message Match Problem
The most common landing page mistake we see is a disconnect between the keyword, the ad, and the page. We call this occurrence the “message match” chain.
If someone searches “commercial HVAC repair,” clicks an ad that says “24/7 Commercial HVAC Repair,” and lands on a page about residential AC installation, you’ve broken the chain. Google notices, the user bounces, and your landing page experience score takes a hit.
The fix isn’t complicated, but it does require intentional page planning. Each high-priority keyword group should have a landing page (or at least a dedicated section of a page) that mirrors the ad’s language and intent. The headline, the opening copy, and the CTA should all reinforce the same message the searcher saw before they clicked.
Other Common Landing Page Mistakes
Aside from message mismatch, there are a few other mistakes people tend to make when it comes to landing pages:
- Weak or missing CTAs leave visitors stranded. If someone clicks an ad that has “get a free quote” in its title and the landing page has no obvious way to request a quote, you’re just wasting money on clicks that won’t convert.
- Generic pages that try to serve multiple ad groups and end up serving none of them well; this ties back to the message match issue. The more specific your page is to the keyword and ad, the higher your landing page experience score will be.
How to Improve Your Google Ads Quality Score
Now that you understand what Quality Score is and what drives it, let’s talk about how to actually move the needle.
Improve Your Expected CTR
Expected CTR is Google’s prediction of how likely your ad is to get clicked, so the goal is to write ads people genuinely want to click, not trick them into clicking.
Write headlines that match the searcher’s specific need.
Generic headlines like “Great Services – Call Today” don’t give the searcher a reason to choose your ad over the other three in the search results. Specific headlines like “Same-Day AC Repair – Licensed Techs” tell the user exactly what they’ll get. If you want a deeper dive into writing better ad copy, our guide to digital ad copywriting covers this in detail.
Use ad extensions (now called “assets”) generously.
Sitelinks, callouts, structured snippets, and call extensions give your ad more real estate on the page and provide additional reasons to click. Google factors extension performance into your expected CTR calculation, so don’t leave them empty.
Test continuously.
Run at least two or three ad variations per ad group and let performance data guide which ones stay. Small changes to headlines, descriptions, or even display URLs can make a measurable difference in CTR. For more on improving your click-through rate in Google Ads, we’ve put together a full guide here.
Boost Ad Relevance
Here’s where campaign structure does the heavy lifting.
Build ad groups around tightly themed keyword clusters.
The old single-keyword ad group (SKAG) approach worked well for years, but Google’s shift toward responsive search ads and broader match types has made it less practical. Instead, group keywords that share the same intent so the same ad copy serves them all. “Emergency plumber,” “24-hour plumber,” and “plumber near me now” can live in the same ad group because they all express the same urgent need and can be addressed by the same ad.
Include your primary keyword naturally in your ad copy.
This doesn’t mean stuffing it into every headline. It means making sure the searcher sees their intent reflected in your ad. If the ad group is themed around “commercial roof repair,” at least one headline and description should address commercial roof repair directly.
Use Dynamic Keyword Insertion (DKI) carefully.
DKI automatically inserts the searcher’s keyword into your ad, which can improve relevance, but can also produce awkward or misleading ads if your keywords aren’t tightly grouped. “Best {KeyWord:Service}” works fine when the keyword is “roof repair,” but looks odd when the keyword is “how much does a new roof cost.” Use DKI as a supplement to already well-written ads, not a replacement for them.
Match the search intent, not just the keywords.
Someone searching “what is a heat pump” wants information, not a sales pitch. Someone searching “heat pump installation near me” is ready to buy. Your ads should reflect the user’s intent. Mixing informational and transactional keywords in the same ad group makes it nearly impossible to write a relevant ad for both.
Optimize Your Landing Pages
Speed matters more than you think.
Every second of load time costs you conversions and hurts your landing page score. Run your key landing pages through Google’s PageSpeed Insights and address any critical issues flagged. Common culprits include uncompressed images, render-blocking scripts, and bloated third-party trackers.
Make the content match the ad’s promise.
The headline on your landing page should echo the headline of your ad. The supporting copy should address the specific need the searcher expressed. If your ad says “Free Consultation for Business Owners,” the landing page should lead with that offer, not bury it below three paragraphs about your company history.
Design for mobile first.
Google evaluates landing page experience based on the device the searcher is using. If more than half of your traffic comes from mobile (and for most advertisers, it does), your mobile experience matters most for Quality Score.
Remove Low-Performing Keywords
Sometimes the best optimization is subtraction. Keywords with persistently low Quality Scores drag down your account’s performance and waste budget on clicks that don’t convert. Review your keyword list regularly and pause or remove keywords that:
- Have a Quality Score of 3 or below with no clear path to improvement
- Show “Below Average” ad relevance that can’t be fixed by restructuring (usually because the keyword doesn’t fit your business)
- Generate clicks but no conversions over a meaningful time period
Pruning irrelevant or underperforming keywords concentrates your budget on the terms where you can actually compete well.
Quality Score for Different Campaign Types
One thing worth noting: Quality Score, as a visible 1–10 metric, applies specifically to Search campaigns. You won’t see a Quality Score column for Display campaigns, Performance Max, or Shopping campaigns in the same way.
That doesn’t mean relevance and quality don’t matter for those campaign types — they absolutely do. Google still evaluates ad relevance, landing page quality, and expected engagement for all ad formats. It just doesn’t surface a neat numeric score for them. The principles we’ve covered here, matching intent, writing relevant copy, and sending traffic to pages that deliver on the ad’s promise, apply across every campaign type. The feedback mechanism is just less transparent outside of Search.
Common Misconceptions About Quality Score
A few myths about Quality Score have stubbornly stuck around, so let’s clear them up:
-
“Quality Score is a KPI I should optimize toward.”
It’s not. Quality Score is a diagnostic tool, not a goal. Chasing a perfect 10 on every keyword can lead you to make decisions that hurt performance, like pausing profitable keywords with a 6 or 7 just because the number isn’t high enough. Use Quality Score to identify problems and guide improvements, but optimize toward actual business outcomes, such as conversions, cost per acquisition, and return on ad spend.
-
“If my Quality Score is low, I just need to bid higher.”
This is probably the most expensive misconception in Google Ads. Higher bids can temporarily improve your Ad Rank, but they don’t fix the underlying relevance and experience issues that caused the low score. You’ll just end up paying more for the same mediocre results.
-
“Quality Score is the same for every auction.”
As we covered earlier, the visible 1–10 score is a static snapshot. The real quality evaluation happens dynamically in each auction, accounting for the searcher’s context, device, location, and more. Two people searching the same keyword at the same time in different cities might trigger different quality assessments for your ad. The visible score is a useful average, but it doesn’t tell the whole story.
-
“Quality Score doesn’t matter anymore.”
You’ll hear this from time to time, usually paired with the argument that Google’s automation handles everything now. While it’s true that Smart Bidding strategies account for quality signals on their own, understanding Quality Score still helps you diagnose why campaigns underperform, structure better ad groups, and write more effective ads.
Frequently Asked Questions
-
What is a good Quality Score in Google Ads?
A Quality Score of 7 or above is generally considered good for most keywords. Branded keywords (such as your company name) often score 8–10 because their relevance is naturally high. Competitive, high-volume keywords might sit at 5–6 even with solid optimization.
-
Does Quality Score affect how often my ads show?
Yes. Quality Score influences your Ad Rank, and Ad Rank determines both your position and whether your ad even shows to anyone at all. A very low Quality Score can mean your ad doesn’t enter the auction for certain queries, effectively reducing your impression share even if your budget and bids are sufficient.
-
Can I see my Quality Score for individual ads?
No. Quality Score is assigned at the keyword level, not the ad level. However, since ad relevance is one of its components, the ads within an ad group do influence the keyword’s Quality Score. If you change your ad copy and the keyword’s ad relevance improves, you know the new ad is doing better.
-
How long does it take for Quality Score to update?
Google doesn’t publish a specific timeline, but significant changes to ad copy, landing pages, or account structure typically take a few days to a few weeks to reflect in your visible Quality Score. The real-time auction-level signals adjust faster, so you might see performance improvements (lower CPCs, better positions) before the visible score catches up.
-
Is Quality Score more important than my bid?
Neither one works in isolation. Ad Rank is a function of both your bid and your quality signals. A great Quality Score with an unrealistically low bid won’t win auctions. But between two advertisers with similar bids, the one with the higher Quality Score will pay less and rank higher.
Focus on Relevance, Not Just Scores
If there’s one thing to take away from all of this, it’s that Quality Score is a symptom, not a cause. It reflects how well your campaigns align with what real people are actually searching for. When your keywords, ads, and landing pages all point in the same direction, toward solving the searcher’s specific problem, Quality Score takes care of itself.
That means the real work isn’t about gaming a number. It’s about understanding what your customers need, writing ads that speak to those needs, and sending them to pages that deliver. Get that right, and the scores, costs, and results follow.
