Quality Score is the Google Ads metric most advertisers know about but least understand. A Quality Score of 5/10 vs 8/10 on the same keyword can mean paying 30–50% more per click for the same ad position. Over a $5,000/month budget, that difference is $1,500–$2,500/month — money that either goes back in your pocket or gets reinvested into more volume. This guide explains exactly how Quality Score is calculated, which of its three components you can actually move, and the changes we've seen most reliably lift scores from below-average to above-average within 30 days.
How Quality Score Is Actually Calculated
Quality Score (1–10) is a diagnostic estimate of your ads' quality relative to other advertisers bidding on the same keyword. It's calculated from three components: Expected Click-Through Rate (how likely your ad is to be clicked for a given query), Ad Relevance (how closely your ad copy matches the search intent of the keyword), and Landing Page Experience (how relevant, transparent, and navigable your landing page is to users arriving from the ad). Each component is rated 'Below Average', 'Average', or 'Above Average'. The combined signal produces your 1–10 Quality Score. A keyword with all three components at 'Average' scores around 5–6/10. All 'Above Average' produces 8–10/10. One 'Below Average' typically drops the overall score to 3–4/10 regardless of the other components. Important: Quality Score is calculated at the keyword level, not the account level. Different keywords in the same campaign can have wildly different Quality Scores. Diagnose at the keyword level, not the account level.
- Quality Score components: Expected CTR (most weighted), Ad Relevance, Landing Page Experience
- Each component: Below Average = 3–4/10 overall; Average = 5–6/10; Above Average = 8–10/10
- One 'Below Average' component drags the full score to 3–4/10 — fix the lowest component first
- Quality Score is keyword-level, not account-level — diagnose per keyword
- Quality Score affects Ad Rank formula: Ad Rank = Bid × Quality Score × Expected Impact of Extensions
- Higher Quality Score = lower CPC for same position: moving from 5/10 to 8/10 typically reduces CPC 25–40%
Fixing Expected CTR: The Highest-Weighted Component
Expected CTR is the most heavily weighted Quality Score component and also the hardest to improve, because it's based on your historical CTR relative to other advertisers on the same keyword. If your ads have been getting poor click-through rates, you've been training a low Expected CTR signal. The fastest path to improving Expected CTR: make your ads more relevant to the specific query by using the keyword in your headline, add extensions that increase ad size and visibility (sitelinks, callouts, structured snippets, call extensions), and use ad copy that matches the specific search intent for each keyword — informational intent needs different copy than transactional intent. One counterintuitive fix: pause low-CTR ad variations actively. If you're running three ads in an ad group and one has a 3% CTR while the other two have 0.8%, the two low-CTR ads are actively training down your Expected CTR signal. Pause them and let the high-performer accumulate data.
- Include the keyword in Headline 1 — exact match or close variant in the first headline improves CTR significantly
- Add all applicable extensions: sitelinks, callouts, structured snippets, call extensions, image extensions
- Pause low-CTR ad variations — they pull down your Expected CTR signal for the keyword
- Match ad copy tone to search intent: transactional queries need price/availability/CTA; informational queries need educational framing
- Ad group CTR benchmark: aim for 5%+ on branded terms, 3%+ on generic, 2%+ on broad/informational
- Dynamic Keyword Insertion (DKI): inserts the user's search term into the ad headline — increases relevance but use carefully to avoid awkward results
Fixing Ad Relevance: The Quickest Win
Ad Relevance 'Below Average' is usually the simplest Quality Score problem to fix. It means your ad copy doesn't closely match the search intent of the keywords in that ad group. The most common cause: ad groups with too many different keyword themes sharing one set of ad copy. The fix is tight ad group structure. Each ad group should contain keywords with a shared intent and shared ad copy. If you have 'Google Ads management' and 'Google Ads consultant' and 'Google Ads expert' in the same ad group, they can share ad copy that speaks to the same intent. But if 'Google Ads management' and 'Google Ads cost' are in the same ad group, 'Below Average' Ad Relevance is predictable — someone searching cost information has different intent than someone searching for management services. Split ad groups by intent theme. Write ad copy specifically for each theme. Ad Relevance typically improves to 'Average' or 'Above Average' within 2–4 weeks of restructuring.
- Below Average Ad Relevance: ad groups contain keywords with mixed intent — split by intent theme
- Rule: each ad group should contain keywords you could write one highly relevant ad for
- Include the primary keyword theme in Headline 1 and Display URL path
- Ad group size recommendation: 5–20 tightly related keywords maximum; don't over-consolidate
- Use SKAGs (Single Keyword Ad Groups) for your highest-volume, highest-value keywords — maximum relevance control
- Rebuilding ad groups from scratch takes 1–2 weeks of work; Quality Score improvement visible within 14–21 days
Fixing Landing Page Experience
Landing Page Experience is the Quality Score component that most affects your conversion rate independently of Google — and it's the one most often neglected. Google evaluates your landing page on relevance to the ad content, loading speed, mobile usability, and page transparency (clear business information, privacy policy, minimal deceptive elements). The fixes that reliably improve Landing Page Experience scores: ensure the landing page headline closely matches the ad copy and keyword (if the ad says 'Google Ads Management for SaaS', the landing page headline should reflect Google Ads management, not a generic digital marketing message); fix mobile page speed (LCP under 2.5 seconds on mobile is the threshold that matters most); ensure the page has visible contact information, a clear business name, and a working privacy policy link; and remove deceptive or misleading elements (overpromised offers, fake urgency, unclear pricing). Landing page changes take 2–4 weeks to be re-evaluated by Google's systems after you make them. Don't expect overnight changes.
- Message match: landing page H1 should directly reflect the ad headline and keyword — generic home pages fail this
- Mobile page speed: LCP under 2.5s on mobile — use PageSpeed Insights for diagnosis
- Transparency signals: visible business name, contact info, working privacy policy link
- Specific landing pages per keyword theme: single landing page for all campaigns is almost always Below Average for landing page experience
- Remove deceptive elements: fake countdown timers, overclaimed results, unclear pricing — Google penalizes these specifically
- Timeline: landing page changes re-evaluated by Google within 2–4 weeks — measure Quality Score 30 days after changes
Quality Score isn't a vanity metric. Every point improvement reduces your CPC, which either cuts your spend for the same lead volume or increases your lead volume for the same spend. Most advertisers treat it as a diagnostic report they glance at occasionally — the ones who actively work on it get a structural cost advantage that compounds over time. Start with the component rated 'Below Average' — that's where the biggest score lift lives. Fix ad relevance first (it's the fastest), then landing page experience, then work on Expected CTR as a sustained effort. Run this audit every quarter. Quality Score drifts as your competition changes and your account evolves.
Frequently Asked Questions
What is a good Quality Score in Google Ads?
Quality Score of 7/10 or above is considered good. Scores of 8–10 indicate your ads, keywords, and landing pages are highly relevant to each other and to user intent — Google rewards these with lower CPCs and better ad positions. Scores of 4–6 are average. Scores of 1–3 indicate significant relevance problems. The priority: eliminate any 'Below Average' component ratings, which drag the overall score down regardless of how good the other components are.
How long does it take to improve Quality Score?
Ad Relevance changes (restructuring ad groups, improving ad copy) typically show improvement in Quality Score within 2–3 weeks as Google collects new performance data. Landing Page Experience changes take 2–4 weeks to be re-evaluated. Expected CTR improvements are slowest because they're based on accumulated historical performance — allow 4–6 weeks to see meaningful movement after making ad copy changes.
Does Quality Score directly affect my Google Ads cost?
Yes, significantly. Quality Score is one of the primary inputs to Ad Rank (Ad Rank = Bid × Quality Score × Expected Extension Impact). A higher Quality Score means Google requires a lower bid from you to achieve the same ad position as a competitor with a lower Quality Score. In practice, moving from Quality Score 5 to 8 on a competitive keyword typically reduces CPC by 25–40% for the same average position.
