Quality Score is Google Ads’ rating of the quality and relevance of your keywords, ads, and landing pages. It is scored on a 1-10 scale at the keyword level, and it directly impacts two things that matter to every advertiser: how much you pay per click and whether your ads show at all.
The relationship is straightforward. Higher Quality Scores mean lower costs per click and better ad positions. Lower Quality Scores mean you pay more for worse placements — or get excluded from auctions entirely. Google has confirmed that Quality Score affects your Ad Rank calculation, which determines both your position and your actual CPC.
This makes Quality Score optimization one of the most cost-effective activities in Google Ads management. A keyword moving from Quality Score 5 to Quality Score 8 can see a 30-50% reduction in CPC without any change to your bid. Multiply that across hundreds of keywords and the savings are substantial.
How Quality Score Actually Works
Google calculates Quality Score from three components, each rated as “Above Average,” “Average,” or “Below Average.”
Expected click-through rate (CTR). This is Google’s prediction of how likely your ad is to be clicked when shown for a given keyword. It is based on the historical CTR of that keyword in your account, adjusted for ad position. This component reflects how relevant and compelling your ad copy is relative to the search query.
Ad relevance. This measures how closely your ad copy matches the intent behind the keyword. If someone searches “GA4 setup service” and your ad talks about generic digital marketing, ad relevance will be low. Google is looking for a clear semantic connection between the keyword, the ad headline, and the ad description.
Landing page experience. This evaluates the quality and relevance of the page users land on after clicking. Google considers page load speed, mobile-friendliness, the relevance of page content to the keyword, and signals of transparency and trustworthiness. A slow, generic page that does not match the ad promise will drag this score down.
Each component contributes to the overall Quality Score, but they are not weighted equally. Expected CTR and landing page experience tend to have the largest impact on your actual CPC and position.
Diagnosing Quality Score Problems
The first step in optimization is diagnosis. Here is how to identify where your Quality Score issues are coming from.
Pull the Quality Score columns. In your Google Ads interface, go to the Keywords tab and add columns for Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. This shows you the component-level ratings for every keyword. Sort by Quality Score ascending to find your worst performers.
Segment by campaign and ad group. Quality Score problems often cluster. If one campaign has consistently low scores, it usually points to a structural issue — the ad groups are too broad, the ads are too generic, or the landing pages do not match. A single ad group with 50 loosely related keywords will almost always have lower Quality Scores than tightly themed ad groups with 5-15 closely related keywords.
Check the component breakdown. If Expected CTR is “Below Average,” the problem is your ad copy — it is not compelling enough relative to competitors. If Ad Relevance is “Below Average,” your keyword-to-ad mapping is too loose — the ads do not directly reference the keyword themes. If Landing Page Experience is “Below Average,” your landing page needs work — it is either slow, irrelevant, or both.
Compare brand vs. non-brand. Brand keywords almost always have high Quality Scores (8-10) because your ad is the most relevant result for your own brand name. These inflate your account average and hide problems with non-brand keywords. Always analyze Quality Score for non-brand keywords separately.
Fixing Expected Click-Through Rate
Expected CTR is the component most directly under your control through ad copy.
Include the keyword in your headline. This sounds basic, but it is the single most impactful thing you can do. If the keyword is “google ads consultant,” your Headline 1 should include “Google Ads Consultant” or a close variant. RSAs (Responsive Search Ads) make this easier because you can provide multiple headline options, but you need to pin your most relevant headline to Position 1 to ensure it shows.
Write benefit-driven descriptions. Your description should answer “why should I click this ad instead of the others?” Focus on specific benefits and differentiators — concrete numbers, unique selling points, and clear value propositions. “$500M+ in Managed Ad Spend” is more compelling than “Experienced Google Ads Professional.”
Use all available ad extensions. Sitelinks, callout extensions, structured snippets, and call extensions increase the visual footprint of your ad, which improves CTR. More importantly, they provide additional information that can make your ad more relevant and clickable. Every extension you add is an opportunity to include additional keywords and benefits.
Test continuously. RSAs allow up to 15 headlines and 4 descriptions. Provide a full set and let Google test combinations, but also monitor performance by asset. Pause underperforming assets and replace them with new variations. Over time, this iterative testing process improves your CTR and your Quality Score.
Fixing Ad Relevance
Ad relevance problems are almost always structural — they come from ad groups that try to cover too many keyword themes with a single set of ads.
Tighten your ad group structure. Each ad group should contain keywords that share the same core intent and can be served by the same ad copy without stretching. “Google Ads management” and “Google Ads audit” might seem related, but they represent different intents and need different ad messages. Split them into separate ad groups.
Create ad copy specific to each ad group. Do not use the same generic ad across multiple ad groups. Each ad group should have ad copy that directly references the keyword theme of that group. This is where many advertisers cut corners, and it directly costs them through lower Quality Scores and higher CPCs.
Use keyword insertion carefully. Dynamic keyword insertion (DKI) can improve ad relevance by automatically including the searched keyword in your ad. However, it can also produce awkward or misleading ads if the keywords in your ad group are too varied. Use DKI as a supplement to well-written, specific ad copy — not as a substitute for it.
Review search terms regularly. Your negative keyword strategy directly impacts ad relevance. If your ads are triggering for irrelevant search queries, those impressions without clicks drag down your expected CTR, and the poor match drags down ad relevance. Regular search term reviews and negative keyword additions are Quality Score hygiene.
Fixing Landing Page Experience
Landing page experience is the component that takes the most effort to improve but often has the largest impact on overall account performance.
Match landing page content to keyword intent. If the keyword is “GA4 setup service,” the landing page should be your GA4 setup service page — not your homepage, not a generic services page. This is the same principle as message match in conversion rate optimization: the page must deliver what the ad promised.
Improve page speed. Use Google PageSpeed Insights to identify and fix speed issues. Compress images, defer non-critical JavaScript, enable browser caching, and consider server-side tracking to reduce client-side tag bloat. Google specifically measures page speed as part of landing page experience.
Ensure mobile-friendliness. Google uses mobile-first indexing, and a significant portion of search traffic is on mobile. If your landing page is not fully responsive with touch-friendly elements, readable text, and fast mobile load times, your landing page experience score will suffer.
Add substantive, relevant content. Google evaluates whether the landing page provides useful, original content related to the search query. Thin pages with just a form and a headline will score lower than pages with detailed information that helps the visitor understand your offering. This does not mean writing 5,000-word essays — it means providing enough content to demonstrate expertise and relevance.
Build trust signals. Google also looks at transparency and trustworthiness. Include clear contact information, privacy policies, testimonials, and business credentials. These signals matter both for Quality Score and for actual conversion rates.
Quality Score Optimization as Ongoing Maintenance
Quality Score is not something you fix once and forget. It shifts as competitors change their ads, as Google updates its algorithms, and as user behavior evolves.
Build Quality Score monitoring into your regular Google Ads audit routine. Pull the Quality Score report monthly, identify any keywords that have dropped, diagnose the specific component causing the decline, and address it. Over time, this systematic approach drives CPCs down and improves your overall account efficiency.
The relationship between Quality Score and bidding strategy is also worth understanding. Automated bidding strategies like Target CPA and Target ROAS already factor in Quality Score indirectly (through the auction dynamics). But higher Quality Scores give these algorithms more room to work — lower CPCs mean more clicks within the same budget, which means more data for the algorithm to learn from. It compounds.

Frequently Asked Questions
What is a good Quality Score in Google Ads?
A Quality Score of 7 or above is considered good for most non-brand keywords. Scores of 8 to 10 are excellent and indicate strong alignment between your keywords, ads, and landing pages. Brand keywords should naturally have Quality Scores of 8 to 10. For competitive non-brand keywords, a score of 6 to 7 is acceptable. Below 5 means there are significant issues with ad relevance, expected click-through rate, or landing page experience that need immediate attention.
Does Quality Score directly affect how much I pay per click?
Yes. Quality Score is a major factor in your Ad Rank, which determines both your ad position and your actual cost per click. A higher Quality Score means you pay less per click for the same position. Roughly, improving your Quality Score from 5 to 7 can reduce your cost per click by 20 to 30 percent. Conversely, a Quality Score of 3 or below means you are paying a significant premium compared to competitors with higher scores for the same keyword.
How do I improve a low Quality Score?
Quality Score has three components: expected click-through rate, ad relevance, and landing page experience. Start by checking which component is below average in your keyword report. For low expected CTR, rewrite ad copy to be more specific and compelling, and use the keyword in your headlines. For low ad relevance, ensure your ad group is tightly themed with closely related keywords. For low landing page experience, improve page speed, match the page content to the keyword intent, and make your page mobile-friendly.
Does Quality Score apply to Performance Max and Display campaigns?
Quality Score as a visible metric only appears in Search and Shopping campaigns. However, Google uses similar relevance and quality signals across all campaign types to determine ad delivery and cost. Performance Max campaigns do not show Quality Score, but the same principles apply: relevant creative, strong landing pages, and accurate audience signals lead to better performance and lower costs. Focus on the underlying quality factors rather than the score itself.
How quickly does Quality Score change after making improvements?
Quality Score updates are not instantaneous. After making changes to ads, keywords, or landing pages, it typically takes a few days to two weeks for Google to re-evaluate and update your Quality Score. The expected click-through rate component updates the fastest (based on recent CTR data), while landing page experience can take longer to reassess. Avoid making additional changes during this evaluation period so you can accurately measure the impact of each improvement.
