Quality Score sits at the centre of every Google Ads auction, and understanding how to influence it is one of the most direct ways to stretch a paid media budget further. Google assigns every keyword a Quality Score on a scale from 1 to 10 based on how relevant your ad and landing page are expected to be to a user’s search query. A higher score generally leads to lower actual costs per click and better ad positions, while a low score signals that something in your account is misaligned with what searchers are looking for. In this guide, we walk through the three components that make up your score, how to diagnose weak spots using data already available in your account, and what practical changes produce the most reliable improvements over time.
What Quality Score Actually Is (and What It Is Not)
Quality Score is Google’s internal rating of the quality and relevance of your keywords, ads, and landing pages. It is not a public ranking metric you can track the way you track a search position, but it directly influences whether your ad appears, where it appears, and how much you pay when someone clicks. At We Define Net, we treat Quality Score as a practical diagnostic tool, a low score tells you that Google’s algorithm does not believe your experience matches what someone is searching for, and that misalignment costs you money with every auction.
It is worth being clear about what Quality Score is not. It is not the same as Ad Rank. Ad Rank determines your ad’s position and is calculated from your maximum bid multiplied by Quality Score, adjusted for the expected impact of ad extensions and other ad formats. Quality Score also does not determine ad eligibility on its own, eligibility depends on policy compliance and a minimum quality threshold, but once an ad is eligible to show, Quality Score becomes one of the most influential levers on cost and position within the auction.
The Three Core Components That Make Up Your Score
Every keyword-level Quality Score is derived from three component ratings that Google reports directly in your account interface: Expected Click-Through Rate, Ad Relevance, and Landing Page Experience. Each of these is rated as Above Average, Average, or Below Average relative to other advertisers targeting the same or similar keywords. The overall Quality Score is an aggregate of these three ratings, which means improving any single component can move the overall score, but identifying which component is the bottleneck requires looking at the individual ratings rather than just the headline number.
How Expected CTR Affects Your Score
Expected CTR is Google’s prediction of how likely someone is to click on your ad when it appears for a given keyword. This is not the same as your actual historical click-through rate, though historical performance does inform the prediction. Google’s algorithm also considers the format of your ad, the presence and strength of your ad extensions, and how well your headline and description match the intent behind the keyword. A Below Average expected CTR rating signals that the ad copy being served does not read as relevant or compelling to someone searching for that specific term.
The most common reason for a low expected CTR rating is ad copy that is too generic for the keyword it is paired with. An ad group that bundles unrelated keywords together forces the advertiser to write copy that tries to cover too many intents at once, and that generic copy performs poorly across all of them. At We Define Net, when we review paid advertising accounts with broad keyword themes, restructuring into tightly focused ad groups is often one of the first changes we make, because it allows each ad to address the specific need behind the search.
How Ad Relevance Gets Overlooked
Ad Relevance is a straightforward rating on paper: does the keyword show up in your ad’s headline, description, or display path in a meaningful way? Google checks whether the search term and the ad text are thematically connected, not just whether the keyword appears somewhere in the ad. An ad that includes the keyword but whose headline reads as a generic brand message will still score Below Average for Ad Relevance, because the algorithm cannot detect a meaningful connection between the query and the message.
The fix for a low Ad Relevance rating is usually simple, include the keyword or a close variation in the headline in a way that reads naturally, but it is surprising how often advertisers write a small number of generic brand messages and leave them running across dozens of unrelated ad groups. Tight, keyword-specific ad copy improves Ad Relevance and also signals to the user that the result is worth clicking, which feeds back into a stronger expected CTR rating. Well-organised ad groups also make content production more efficient, because each group has a clear topic and a clear audience to write for.
Landing Page Experience in Depth
Landing Page Experience measures how well the page someone lands on after clicking your ad delivers on what the ad promised. Google evaluates the relevance of the page content to the keyword, the transparency of the page, who you are, what you do, how you handle customer information, and the usability of the page on both desktop and mobile devices. Page load speed, mobile-friendliness, and the clarity of the navigation all factor into the rating.
A very common pattern is a keyword with a strong ad score paired with a generic homepage that does not address the specific search intent. If someone searches for “enterprise project management software” and lands on a homepage that reads like a company overview with no mention of project management features, the disconnect will drag down the Landing Page Experience rating. A dedicated landing page that speaks to the specific intent behind the keyword, even a straightforward page with targeted copy and a clear call to action, can move this rating from Below Average to Average or above. For advertisers who need a tailored page built to spec, professional web development services can deliver a campaign-specific experience that aligns with both ad messaging and brand standards.
How to Diagnose Which Components Are Holding Your Score Down
Google Ads makes the three component ratings visible at the keyword level, so diagnosing the problem is more straightforward than many advertisers realise. Open your Google Ads account, navigate to the Keywords tab, and add the Quality Score columns to your view: Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. Sort by Quality Score and start with the keywords scoring 4 or below.
The component ratings tell you exactly where to focus. If Expected CTR is Below Average but Ad Relevance and Landing Page Experience are fine, your ad copy is the problem and you do not need to touch your landing pages. If Ad Relevance is Below Average, your ad text is not connected closely enough to the keyword. If Landing Page Experience is Below Average, the page your ad sends traffic to is not delivering on the promise of the ad. In many accounts, one component is the clear weak link while the other two perform adequately, which means a targeted change can produce a noticeable improvement without a full account overhaul.
A Framework for Improving Quality Score Across All Three Components
Improving Quality Score is not about finding one magic change, it is about systematically strengthening each component rating. The table below maps the three components to the common signs of a low rating and the practical actions that address each one. Use it as a working checklist when reviewing keywords that score below 5.
| Component | Common Signs of a Low Rating | Practical Actions to Improve |
|---|---|---|
| Expected CTR | Low historical CTR on the keyword; ad copy that is identical across multiple unrelated ad groups; missing or minimal ad extensions | Write keyword-specific headline copy; use all available headline and description slots; add sitelink, callout, structured snippet, and call extensions; test stronger calls to action in your description text |
| Ad Relevance | Keyword does not appear in the ad headline; ad text is the same across many keyword groups with different themes; headline reads generically | Insert the keyword or a close variation in headline 1; tailor description text to the keyword’s specific intent; use display paths that reflect the landing page topic |
| Landing Page Experience | All keywords send traffic to the homepage regardless of intent; slow page load times on mobile; page content does not match what the ad promised; poor mobile navigation | Create dedicated landing pages for high-intent keyword clusters; improve page load speed through image compression and script reduction; ensure mobile responsiveness; align page copy with ad messaging |
Common Mistakes That Keep Quality Score Low
After reviewing accounts across industries, certain patterns appear repeatedly. The first is sending every keyword’s traffic to a single homepage regardless of search intent. A homepage is designed to serve a general audience, not a specific intent, so it will almost always underperform for Landing Page Experience compared to a targeted page. A user who searches for “cloud backup for small business” and lands on a homepage that introduces the entire company without mentioning cloud backup will leave, and Google records that as a poor experience.
The second pattern is using identical ad copy across unrelated keyword groups. This keeps Ad Relevance low because the ad text cannot be meaningfully connected to every keyword it serves for. The third pattern is neglecting ad extensions entirely. Extensions provide additional real estate on the search results page, make your ad more visually prominent, and give users more reasons to click. Accounts that use multiple relevant extensions consistently outperform accounts that rely on headline and description alone. The fourth pattern is letting underperforming keywords linger indefinitely. Keywords that consistently receive very few impressions or very low CTRs drag down account-level metrics and can influence how Google evaluates the broader account over time.
There is also a longer-term structural mistake that many advertisers make: treating paid search and organic search as separate disciplines. The keyword research, intent mapping, and content themes that support strong organic performance also support strong Quality Scores. Accounts that invest in foundational search engine optimisation alongside paid media often find that Quality Score improvements compound across both channels, because the themes and landing page content work for organic and paid efforts at the same time.
How Quality Score Changes Affect Your Cost Per Click
Quality Score does not set a minimum price you must pay, that is determined by your bid, but a higher Quality Score reduces the actual cost per click you are charged in an auction. Google calculates actual CPC using a formula where the advertiser in the position below you pays just enough to beat your Ad Rank. Because Ad Rank is a function of bid and Quality Score multiplied together, a higher Quality Score means you can achieve the same Ad Rank with a lower bid, or maintain the same bid at a lower actual CPC.
In practical terms, moving a keyword from a Quality Score of 3 to a Quality Score of 7 can reduce the actual CPC by a meaningful margin. The exact reduction varies by industry and competition level, but the direction is consistent: better relevance across all three components means cheaper clicks for the same budget, which means more traffic and more conversion opportunities for the same spend. This is why we treat Quality Score improvements as a cost-reduction strategy rather than simply a technical metric to chase.

When to Expect Results From Quality Score Improvements
Quality Score does not change overnight. Google needs to accumulate new data about how users respond to your updated ads and landing pages before it recalculates the component ratings, and that process can take anywhere from a few days to several weeks depending on the keyword’s impression volume. High-volume keywords with plenty of daily searches will generate enough click and impression data for an update relatively quickly, while low-volume keywords in niche markets may take longer to reflect the changes you have made.
The practical approach is to make changes systematically, allow at least one to two weeks for data to accumulate, and then check the component ratings again. Prioritise your highest-spend keywords first, because improvements to those keywords have the largest impact on your overall budget efficiency. Do not expect a Quality Score of 10 for every keyword, scores of 7 to 9 are realistic for most accounts and deliver most of the cost advantage, while a score of 10 is often unnecessary and occasionally unattainable for very competitive terms with aggressive competition.
Frequently asked questions
What is a good Quality Score?
A Quality Score of 7 or above is generally considered strong across most industries. Scores in this range indicate that Google views your keywords, ads, and landing pages as relevant to user intent. Scores of 8 to 10 are excellent and typically deliver the lowest possible cost per click within an auction. Scores of 4 to 6 suggest there is room for improvement in one or more of the three components. Scores of 1 to 3 signal a significant relevance problem that is likely costing you more per click than necessary, and these keywords should be reviewed as a priority.
How long does it take to improve Quality Score?
Quality Score improvements typically become visible within one to three weeks after you make changes to your ad copy or landing pages. Google needs enough new impression and click data to recalculate the component ratings, and the accumulation period varies by keyword search volume. High-traffic keywords may show updated scores within a few days, while lower-volume keywords can take several weeks. We recommend reviewing your scores on a bi-weekly schedule after making structural changes rather than checking daily, as daily fluctuations in individual keyword data can be misleading.
Does Quality Score affect every type of Google Ads campaign?
Quality Score directly influences search campaigns, and it applies to keywords within Performance Max and Smart Shopping campaigns as well, though the mechanism is slightly different in automated campaigns where Google controls the ad assembly. Display Network campaigns, YouTube campaigns, and demand generation campaigns do not use the same keyword-level Quality Score system, but relevance and user experience still influence cost and delivery in those formats through related performance metrics. The underlying principle, that better relevance leads to better efficiency, holds across every Google Ads channel.
Can I improve Quality Score without changing my landing pages?
Yes. If Ad Relevance or Expected CTR is the Below Average component, you can improve your overall Quality Score by adjusting your ad copy, restructuring your ad groups, and adding ad extensions without touching your landing pages. Many accounts see meaningful gains from ad-side changes alone. However, if Landing Page Experience is the weak component, which is common when all keywords in an account send traffic to a generic homepage, you will eventually need to address the page experience to reach a higher overall score. Diagnosing the specific weak component before making changes is the key to working efficiently.
Should I pause keywords with a low Quality Score?
Not automatically. A keyword with a low Quality Score but strong conversion performance may still be worth keeping, because the revenue it generates can offset the higher cost per click. The right approach is to diagnose which component is Below Average and attempt a fix first, such as writing more relevant ad copy or pointing to a more targeted landing page, before deciding to pause. If the keyword continues to underperform across relevance, cost, and conversions after you have addressed all three components, then pausing it and reallocating that budget is a reasonable decision.
Does Quality Score matter if I am already bidding for the top ad position?
It matters significantly, because even at the top position, a higher Quality Score reduces the actual amount you are charged per click. An advertiser with a Quality Score of 9 can pay substantially less per click than an advertiser with a Quality Score of 4 who is bidding more aggressively to achieve the same position. Quality Score also acts as a buffer against competitors: a strong score means you can maintain your position while bidding less, which preserves budget for other keywords in your account. This compounding effect is one reason we integrate Quality Score reviews into every PPC management engagement we take on.
