Quality Score is one of the most misunderstood metrics in all of Google Ads — practitioners obsess over the number itself when they should be focused on the underlying signals driving it. After managing over $350M in Google Ads spend, I can tell you that chasing a "10/10" Quality Score is the wrong frame entirely. What you actually want is a lower Cost Per Click, better ad rank, and ultimately a lower Cost Per Acquisition — and Quality Score is simply the lever that gets you there. A common question in the r/googleads community centers on which of the three components (CTR, ad relevance, and landing page experience) matters most, and the short answer is: it depends on where your score is broken. Let me show you exactly how to diagnose and fix each one.
What Quality Score Actually Is (And Why the Number Itself Is a Trap)
Quality Score is Google's 1–10 rating of the relevance and quality of your keywords, ads, and landing pages. It directly affects your Ad Rank and the CPC you pay in every auction. But here's where most advertisers go wrong: they treat Quality Score like a report card to be improved for its own sake.
In reality, Quality Score is a diagnostic tool. The three sub-components — Expected CTR, Ad Relevance, and Landing Page Experience — each rated as Below Average, Average, or Above Average — tell you precisely where the friction is in your account. Your job is to fix the friction, not game the score.
Key Insight: A Quality Score of 7 on a high-volume, high-intent keyword can be worth more than a 10 on a keyword nobody searches. Always weight your Quality Score improvements by impression volume and commercial value, not just the rating itself.
Here's how Quality Score translates to real auction economics. Google publishes approximate CPC adjustment multipliers based on Quality Score:
| Quality Score |
CPC Adjustment vs. QS 6 Baseline |
Real-World Impact |
| 1 |
+400% |
Paying 5x more than necessary |
| 3 |
+67% |
Severely disadvantaged CPC |
| 5 |
+25% |
Slightly above average cost |
| 6 |
Baseline |
Average advertiser |
| 7 |
-14% |
Meaningful savings at scale |
| 9 |
-33% |
Significant competitive advantage |
| 10 |
-50% |
Best-in-class efficiency |
When you're spending $50,000/month on a keyword cluster sitting at QS 4, moving to QS 7 can mean $15,000–$20,000 in monthly savings or reinvestment capacity. That's the real reason to care.
Component #1: Expected CTR — The Highest-Leverage Signal
As practitioners often discuss in the r/googleads community, Expected CTR is generally the most impactful of the three components for moving your Quality Score. This is because it's the one Google can measure most objectively and at scale. It's not your actual CTR — it's Google's prediction of how likely a user is to click your ad given the keyword, based on historical data across all advertisers.
How to Diagnose CTR Problems
Pull your keywords report and filter for "Below Average" Expected CTR. Sort by impressions descending. You're looking for high-volume keywords where users are seeing your ad and consistently choosing not to click. That's a messaging problem.
- Industry average CTRs vary widely: Search CTRs typically range from 2–6% for competitive commercial terms, and 6–15%+ for branded terms
- If your non-branded search CTR is below 2%, your ad copy is almost certainly the culprit
- If CTR drops sharply on mobile vs. desktop (check device segmentation), your mobile ads may need separate optimization
Tactical Fixes for Below-Average Expected CTR
- Use the keyword in your headline: Dynamic Keyword Insertion (DKI) can help at scale, but manual inclusion of your exact match keyword in Headline 1 consistently outperforms DKI in my experience — especially for RSAs where Google assembles combinations dynamically.
- Lead with the user's problem, not your solution: "Struggling with [Pain Point]? We Fix That" outperforms "We Offer [Service] in [City]" in nearly every test I've run.
- Use all available ad extensions (now called Assets): Sitelinks, callouts, structured snippets, and call assets all increase your ad's visual footprint and improve CTR. Accounts missing these are leaving 10–25% CTR improvement on the table.
- Pin high-CTR headlines in your RSAs: Test, identify your top-performing headlines via asset performance ratings (Best/Good/Low), then pin your proven winners in position 1 while allowing Google to test positions 2 and 3.
- Segment by match type: Broad match keywords often have lower Expected CTR because the intent signals are more diffuse. Consider tightening to phrase or exact match for your highest-value terms.
Best Practice: Run a dedicated "CTR Recovery" experiment in Google Ads for any keyword cluster sitting at Below Average Expected CTR. Isolate 3–4 new RSA variations, run a 50/50 traffic split for 4–6 weeks, and let data (not gut feeling) select the winner. The Google Ads Experiments tool makes this clean and statistically valid.
Component #2: Ad Relevance — The Structural Fix
Ad Relevance measures how closely your ad copy aligns with the keyword's intent. Unlike CTR, this is more within your direct control — it's a structural account problem, not a messaging problem.
The Root Cause: Ad Group Structure
The single most common cause of Below Average Ad Relevance is over-broad ad groups. If you have one ad group containing keywords like "enterprise CRM software," "CRM for small business," and "free CRM trial," you cannot write one set of ads that is highly relevant to all three intents simultaneously. They represent completely different buyers.
Common Mistake: Building ad groups around product categories instead of search intent. "CRM Software" is a category. "CRM software for 5-person teams" is an intent. The ad copy, landing page, and offer that converts intent-based traffic is fundamentally different — and Google knows it.
How to Fix Ad Relevance
- Adopt Single Keyword Ad Groups (SKAGs) for your highest-value terms: Yes, they're more work to manage. Yes, they still produce better Ad Relevance scores for exact-match commercial terms in 2024. Use them selectively on your $50+ CPC, high-conversion keywords.
- Theme-cluster your RSA ad groups: For lower-volume terms, group keywords by micro-intent — all "price/cost" variants together, all "how-to" variants together, all "best/top" variants together.
- Include your keyword's core term in at least 2 of your RSA headlines: If the keyword is "project management software for agencies," the word "agency" or "agencies" should appear in your headline. Every time.
- Review your keyword-to-ad relevance ratio: A good benchmark is no more than 15–20 keywords per ad group for RSAs. Above that, you're almost certainly diluting relevance.
Key Insight: Ad Relevance "Below Average" on a keyword almost always means the keyword is in the wrong ad group. Before rewriting your ads, ask whether the keyword actually belongs where it is. Moving one keyword to a better-matched ad group can flip it from Below Average to Average overnight.
Component #3: Landing Page Experience — The Highest-Effort, Highest-Reward Fix
Landing Page Experience is where most accounts have their biggest untapped Quality Score gains — and where most advertisers spend the least time. Google evaluates relevance, transparency, ease of navigation, load speed (especially on mobile), and the degree to which your page delivers on what your ad promises.
The Message Match Problem
If your ad headline says "Free 14-Day Trial — No Credit Card Required" and your landing page opens with your company's brand story and a generic contact form, you have a message match failure. Google's crawler and user behavior signals both flag this. Your bounce rate goes up, time-on-site goes down, and your Landing Page Experience rating drops.
The fix is brutally simple: your landing page headline should functionally mirror your ad headline. The offer in the ad should be the first thing visible above the fold on the landing page. No exceptions.
Technical Landing Page Factors That Kill Quality Score
- Mobile page speed: Google's Core Web Vitals are a real factor. Use Google PageSpeed Insights (free) to benchmark your landing pages. A Largest Contentful Paint (LCP) above 4 seconds on mobile is a Quality Score killer. Aim for under 2.5 seconds.
- Intrusive interstitials: Pop-ups that trigger immediately on page load, especially on mobile, are explicitly flagged by Google as poor landing page experience. Use exit-intent pop-ups instead, or delay triggers to 30+ seconds.
- Thin or irrelevant content: Google wants to see that your page genuinely satisfies the search intent. A 200-word landing page for a competitive B2B software keyword will consistently underperform a well-structured 600–800 word page with clear value propositions, social proof, and a relevant CTA.
- HTTPS and site security: If your landing page is still on HTTP in 2024, you have bigger problems than Quality Score — fix this immediately.
- Redirect chains: Final URL pointing to a URL that redirects 2–3 times before reaching the real page adds latency and signals poor user experience. Use the final URL directly.
Best Practice: Build dedicated landing pages for your top 20% of keywords by spend. Don't send high-intent paid traffic to your homepage or a generic product page. Even a simple, fast-loading page with a matched headline, 3–5 bullet benefit points, a testimonial, and a clear CTA will outperform your main website for Quality Score and conversion rate. In my experience, dedicated landing pages improve Landing Page Experience ratings within 2–4 weeks of consistent traffic.
Account Structure & Historical Data: The Hidden Quality Score Drivers
Beyond the three rated components, there are account-level factors that influence Quality Score that most guides don't talk about.
Historical Account Performance
New accounts and new keywords start with limited Quality Score data. Google assigns a baseline score (typically 6) until sufficient impression data accumulates. Don't panic if your brand-new keyword launches at QS 5–6 — this is normal. What matters is the trajectory over the first 30–60 days. If you're declining toward 3–4, that's a structural problem. If you're climbing toward 7–8, you're on the right track.
Keyword Match Type Strategy
Broad match keywords in 2024 have become far more powerful with Smart Bidding, but they almost always carry lower Quality Scores than exact match equivalents. This is expected behavior — Google is matching your ad to a wider range of queries, so the Expected CTR and Ad Relevance scores are naturally more diffuse. Your strategy should be:
- Use exact match for your highest-value, highest-confidence commercial terms — these will carry your highest Quality Scores
- Use phrase & broad match with Smart Bidding for discovery and expansion — accept that QS will be lower, but measure by ROAS/CPA, not QS
- Never evaluate Quality Score across match types in aggregate — segment them in your analysis
Negative Keywords & Search Term Hygiene
Irrelevant search terms silently destroy your Expected CTR. If your keyword "project management software" is matching to "project management software free download crack," users are seeing your paid ad and not clicking — rightfully so. That click-through failure registers against your Expected CTR.
Run your Search Terms report weekly. Add negatives aggressively. A clean, tightly-matched keyword-to-query relationship is foundational to maintaining strong Quality Scores over time.
How Long Does Quality Score Improvement Take?
This is one of the most common follow-up questions, and the honest answer is: it depends on volume. Quality Score updates are based on impression thresholds, not time. Here are realistic benchmarks from my experience:
- High-volume keywords (10,000+ impressions/month): Changes to ads or landing pages can reflect in Quality Score within 1–2 weeks
- Medium-volume keywords (1,000–10,000 impressions/month): Expect 3–6 weeks to see meaningful movement
- Low-volume keywords (<1,000 impressions/month): Quality Score data is sparse and may show "—" for individual components. Focus your energy elsewhere.
Patience is required, but don't confuse patience with passivity. Make your structural changes, document them, and set a calendar reminder to re-audit in 30 days.
What to Do Next: Your Quality Score Action Plan
Stop chasing the number. Start fixing the friction. Here's your prioritized action list:
- Audit your keyword components now: Pull a keyword report, add the Expected CTR, Ad Relevance, and Landing Page Experience columns, filter for "Below Average" on any component, and sort by impressions. This is your priority repair list.
- Fix your highest-spend "Below Average" keywords first: If a keyword is spending $5,000/month at QS 4, moving it to QS 7 could save you $1,000–$1,500/month at current volume. That's your ROI on the optimization time.
- Audit landing page message match for your top 10 keywords by spend: Open each ad, click through to the landing page, and ask honestly: "Does this page immediately deliver on what the ad promised?" If not, fix the page before you touch the ad.
- Run PageSpeed Insights on your top 5 landing pages: Get your mobile LCP under 2.5 seconds. This alone can shift Landing Page Experience from Average to Above Average in competitive categories.
- Review and tighten your negative keyword lists monthly: Irrelevant query matching is a silent Quality Score killer. A clean search terms report is the foundation of strong Expected CTR scores over time.
Quality Score improvement isn't a one-time project — it's an ongoing practice. The accounts I've seen consistently achieve QS 8–10 on their core keywords aren't doing anything magical. They're just relentless about message match, account structure hygiene, and landing page relevance. Build those habits and the score takes care of itself.
