What Is Google Ads Quality Score?
Quality Score grades your keywords.
Quality Score is a diagnostic metric in Google Ads rated from 1 to 10 that estimates the quality of your ads, keywords, and landing pages. According to Google Ads Help, Quality Score is calculated using three components: expected click-through rate (CTR), ad relevance, and landing page experience. Higher scores lead to lower costs and better ad positions.
Google assigns a Quality Score to every keyword in your account. It is not a hidden number — you can view it directly in your keywords report. The score reflects how well your ad experience matches what a searcher is looking for. A score of 7 or higher means Google considers your keyword-ad-landing page combination above average. A score below 5 means you are overpaying for every click.
The reason Quality Score matters is mechanical. Google uses it in the ad auction formula that determines both your ad position and your actual cost per click. The formula is straightforward: Ad Rank = Max Bid x Quality Score. Two advertisers bidding on the same keyword with different Quality Scores will pay different amounts for the same position. The advertiser with a higher Quality Score pays less.
This is not a marginal difference. Across thousands of auctions per day, a Quality Score improvement from 5 to 8 can reduce your cost per click by 30-50%. For ecommerce brands spending $10,000 or more per month on Google Ads, that translates to thousands of dollars saved — or reinvested into additional traffic.
How Does Quality Score Affect Your CPC and Ad Rank?
Google uses Quality Score as a multiplier in its ad auction. A WordStream analysis of over 2,000 Google Ads accounts found that advertisers with above-average Quality Scores (7-10) pay 16-50% less per click than the benchmark CPC, while advertisers with below-average scores (1-4) pay 25-400% more, according to their Quality Score benchmark report.
The relationship between Quality Score and CPC is not linear — it is exponential at the low end. Dropping from a 5 to a 3 hurts more than improving from a 7 to a 9 helps. This is why fixing your worst-performing keywords has a larger budget impact than optimizing your best ones.
Here is the actual CPC impact by Quality Score level, based on aggregated industry data:
| Quality Score | CPC Adjustment vs. Benchmark | Effective CPC at $2.00 Benchmark | Ad Rank Impact |
|---|
| 10 | -50% | $1.00 | Highest position, lowest cost |
| 9 | -44% | $1.12 | Strong position advantage |
| 8 | -37% | $1.26 | Above-average efficiency |
| 7 | -28% | $1.44 | Baseline "good" performance |
| 6 | -16% | $1.68 | Slight discount |
| 5 | 0% (benchmark) | $2.00 | Average — no advantage |
| 4 | +25% | $2.50 | Paying a penalty |
| 3 | +67% | $3.34 | Significant overpayment |
| 2 | +150% | $5.00 | Budget drain |
| 1 | +400% | $10.00 | Effectively uncompetitive |
An advertiser with a Quality Score of 3 pays $3.34 for the same click that costs a Quality Score 8 advertiser $1.26. That is 2.6x more for identical traffic. Over a month of 5,000 clicks, the difference is $10,400.
Quality Score also determines whether your ad shows at all. Google calculates an Ad Rank threshold — a minimum score needed to appear in a given position. If your Quality Score is too low, your ad does not enter the auction regardless of how high you bid. This is why some keywords appear to have no impressions despite having active bids above the suggested range.
For ecommerce brands deciding where to allocate budget between Google and Facebook, Quality Score is the variable that makes Google Ads either a profitable channel or a money pit. The same $5,000 budget produces drastically different results depending on account-level Quality Score health.
What Are the Three Components of Quality Score?
Quality Score is built from three sub-metrics, each rated as "Above average," "Average," or "Below average." According to Google Ads Help, these are: expected click-through rate (how likely your ad is to be clicked), ad relevance (how closely your ad matches searcher intent), and landing page experience (how useful and relevant your landing page is to the searcher).
Expected Click-Through Rate (Expected CTR)
Expected CTR predicts how likely your ad is to be clicked when shown for a particular keyword. Google calculates this using historical performance data across your account and across all advertisers bidding on that keyword. It is normalized — meaning your actual CTR is compared against other ads in the same position.
A "Below average" expected CTR rating means your ad copy is not compelling enough relative to competitors. The fix involves writing ads that directly address the searcher's query, using the keyword in the headline, and including a clear value proposition.
Ad Relevance
Ad relevance measures how closely your ad copy matches the intent behind the keyword. If someone searches "women's running shoes size 8" and your ad headline says "Athletic Footwear Sale," Google sees a relevance gap. The ad is related to the topic but does not match the specific intent.
Ad relevance is the component most directly under your control. Tight ad group structures — where each ad group contains 10-20 closely related keywords with ad copy written specifically for those terms — produce "Above average" ratings consistently.
Landing Page Experience
Landing page experience evaluates the page users land on after clicking your ad. Google assesses relevance (does the page content match the ad and keyword), load speed, mobile usability, and transparency (clear business information, accessible privacy policy).
This component connects your Google Ads performance to your broader conversion tracking setup. A landing page that loads slowly or does not match the ad promise will hurt Quality Score even if your CTR and ad relevance are strong.
Each component carries roughly equal weight, but expected CTR tends to have the largest marginal impact on the final 1-10 score. Improving a "Below average" expected CTR to "Above average" can shift your Quality Score by 2-3 points.
How Do You Check Your Quality Score in Google Ads?
Quality Score is visible in the Keywords tab of your Google Ads account. You need to add the Quality Score columns manually — by default, they are hidden. Go to Keywords > Columns > Modify columns > Quality Score, then check "Quality Score," "Exp. CTR," "Ad relevance," and "Landing page exp." to see all four metrics at once.
Step-by-Step: Viewing Quality Score
- Log into Google Ads
- Navigate to the campaign or ad group level
- Click Keywords in the left menu
- Click the Columns icon (three vertical lines)
- Click Modify columns
- Expand the Quality Score section
- Add: Quality Score, Exp. click-through rate, Ad relevance, Landing page exp.
- Optionally add historical Quality Score columns to track changes over time
- Click Apply
You can also segment by Quality Score to identify patterns. Filter for keywords with Quality Score 1-4 and sort by spend — this shows you exactly where budget is being wasted on underperforming keywords.
What to Do With the Data
Prioritize keywords by spend multiplied by Quality Score gap. A keyword spending $500/month with a Quality Score of 3 should be fixed before a keyword spending $50/month with a Quality Score of 5. The budget impact determines the priority, not the score alone.
What Are the 10 Best Ways to Improve Quality Score?
Improving Quality Score requires changes across ad copy, account structure, and landing pages. The tactics below are ordered by impact — starting with structural changes that affect multiple keywords simultaneously, then moving to granular optimizations for individual keywords.

1. Restructure Ad Groups Around Tight Keyword Themes
The single highest-impact change is breaking large ad groups into smaller, tightly themed groups. An ad group with 50 keywords cannot have ad copy that matches every term. Split into groups of 10-15 keywords that share identical intent, then write ads specific to each group.
A keyword like "buy leather laptop bag" and "leather messenger bag for work" belong in different ad groups despite both being leather bags. The search intent is different, and the ad copy should reflect that.
2. Write Headlines That Mirror Search Queries
Include the primary keyword in Headline 1. Not buried in the description — in the first headline. Google bolds keyword matches in ad copy, which increases CTR and signals relevance simultaneously. Both expected CTR and ad relevance improve from this single change.
Use dynamic keyword insertion (DKI) sparingly. It works for simple keyword variations but produces awkward headlines when keyword groups are too broad.
3. Align Landing Pages to Ad Group Intent
Each ad group should point to a landing page that matches the specific keyword theme. Sending all traffic to your homepage guarantees a "Below average" landing page experience. If someone clicks an ad for "organic dog treats for small breeds," the landing page should show organic dog treats filtered for small breeds — not your full product catalog.
For brands running product-specific campaigns, use filtered collection pages or dedicated landing pages optimized for conversion as destinations.
4. Improve Page Load Speed
Google measures landing page load time as part of the landing page experience component. Pages loading in over 3 seconds on mobile receive lower scores. Use Google's PageSpeed Insights to identify bottlenecks.
Common fixes for ecommerce:
- Compress product images to WebP format
- Defer non-critical JavaScript
- Use a CDN for static assets
- Reduce third-party script count (every tracking pixel adds latency)
5. Add Negative Keywords to Block Irrelevant Traffic
Negative keywords indirectly improve Quality Score by preventing your ads from showing for searches that will not result in clicks. When irrelevant impressions are removed, your CTR rises — and expected CTR is the most influential Quality Score component.
Review your Search Terms report weekly. Every irrelevant query you find and add as a negative keyword improves the ratio of relevant impressions to total impressions.
6. Use All Available Ad Extensions
Ad extensions (now called assets) increase ad real estate and provide additional information. Sitelinks, callouts, structured snippets, price extensions, and image extensions all improve CTR by making your ad more visible and more informative. Higher CTR feeds directly into expected CTR scores.
Google recommends at least 4 sitelinks, 4 callouts, and 2 structured snippet headers per campaign. Accounts with full extension coverage consistently outperform accounts with minimal extensions.
7. Test Ad Copy Continuously
Run at least 3 responsive search ad variations per ad group. Google rotates these and learns which combinations perform best. Test specific elements:
- Different value propositions in headlines
- Price vs. benefit-focused descriptions
- Urgency (limited time) vs. trust (reviews, ratings) messaging
- Different calls to action (Shop Now vs. Browse Collection vs. Get Free Shipping)
Kill underperformers monthly. Replace them with new variations. This ongoing testing cycle ratchets up expected CTR over time.
8. Match Landing Page Content to Keywords
Beyond structural alignment (tactic 3), the actual text on your landing page matters. Google's crawlers evaluate whether your page content is relevant to the keyword. If your ad group targets "wireless noise-canceling headphones," that exact phrase — or close variants — should appear in your landing page headline, subheadings, or product descriptions.
This does not mean keyword stuffing. It means using natural, descriptive language that matches what the searcher typed.
9. Improve Mobile Landing Page Experience
Google evaluates mobile experience separately. A page that works well on desktop but has tiny buttons, horizontal scrolling, or pop-ups covering content on mobile will receive a poor landing page experience score. Over 60% of Google searches happen on mobile — if your mobile experience is poor, most of your Quality Score assessments are being penalized.
Test every landing page on actual mobile devices. Chrome DevTools mobile emulation misses some issues that real device testing catches.
10. Pause or Restructure Low-Scoring Keywords
Keywords with a Quality Score of 1-3 that have been running for 30+ days without improvement are dragging down your account. Pausing them removes their negative influence on account-level performance. If the keyword is important, move it to a new campaign with fresh ad copy and a dedicated landing page. A fresh start sometimes produces better results than incremental fixes.
Use the right bidding strategy for rebuilt campaigns — start with manual CPC to control costs while the new Quality Scores stabilize, then transition to automated bidding once scores reach 6+.
How Long Does It Take to Improve Quality Score?
Quality Score updates are not instant. Google recalculates Quality Score each time your keyword enters an auction, but visible changes in the 1-10 score typically take 1-2 weeks of accumulated data after you make changes. Structural improvements (ad group restructuring, new landing pages) show results faster than copy-only changes, according to observations from Search Engine Journal.
The timeline depends on impression volume. High-volume keywords (1,000+ impressions/week) recalculate faster because Google accumulates more data points. Low-volume keywords can take 30+ days to reflect changes.
Here is a realistic improvement timeline:
| Action Taken | Expected Score Change | Timeline to See Impact |
|---|
| Restructure ad groups (10-15 keywords each) | +1 to +3 points | 1-2 weeks |
| New landing pages matching ad group intent | +1 to +2 points | 2-3 weeks |
| Rewrite ad copy with keyword in Headline 1 | +1 to +2 points | 1-2 weeks |
| Add all ad extensions | +0.5 to +1 point | 1-2 weeks |
| Improve page load speed below 2 seconds | +0.5 to +1 point | 2-4 weeks |
| Add negative keywords (100+ terms) | +0.5 to +1 point (via CTR lift) | 2-3 weeks |
These improvements compound. Restructuring ad groups AND rewriting ad copy AND improving landing pages simultaneously can shift a Quality Score from 4 to 8 within a month. Making one change at a time stretches the process to 3-4 months.
Do not expect a linear path. Quality Scores often dip briefly after structural changes (because new ad copy has no historical data) before climbing above the previous baseline. Resist the urge to revert changes during the first week.
What Mistakes Destroy Quality Score?
The most common Quality Score killers are broad ad groups with 50+ keywords, sending all traffic to a single homepage, and ignoring the Search Terms report. Each of these creates a cascading failure — irrelevant impressions lower CTR, low CTR signals poor relevance, and poor relevance increases CPCs.
Using a single ad group for everything. This is the most frequent structural error. An ad group called "All Products" with 200 keywords and two generic ads will never achieve high Quality Scores. The math does not work — you cannot write a single ad that is relevant to 200 different search intents.
Ignoring mobile landing page experience. Desktop scores and mobile scores are calculated independently. A page with a 95 PageSpeed score on desktop and a 40 on mobile will receive a "Below average" landing page experience for the majority of your traffic.
Setting and forgetting ad copy. Quality Score is relative to your competitors. If competitors improve their ads and you do not, your expected CTR drops even without any change on your end. Quarterly ad refreshes are the minimum; monthly testing is the standard for competitive categories.
Bidding on irrelevant keywords for volume. Adding broad match keywords without corresponding negative keywords floods your account with irrelevant impressions. Each non-click impression pushes your expected CTR down. Volume-first strategies that ignore relevance create a Quality Score debt that takes months to recover from.
Slow landing pages. Every second of load time above 3 seconds reduces mobile conversions by 20%, according to Google's own data. Quality Score penalizes slow pages not because speed is an arbitrary metric, but because slow pages deliver a poor user experience — and Google does not want to send users to pages that frustrate them.
Frequently Asked Questions
Does Quality Score affect Smart Bidding strategies?
Yes. Smart Bidding strategies like Target ROAS and Maximize Conversions still operate within the ad auction system, where Quality Score determines your Ad Rank and actual CPC. A higher Quality Score means Smart Bidding can win the same auctions at a lower cost, giving the algorithm more room to find conversions within your budget. Improving Quality Score makes every bidding strategy more efficient.
Is Quality Score calculated at the keyword, ad group, or account level?
Quality Score is displayed at the keyword level, but Google also uses an account-level quality signal in its auction calculations. New keywords in accounts with a history of high Quality Scores tend to start with slightly better scores than the same keywords in underperforming accounts. This is sometimes called "account-level Quality Score" in the industry, though Google does not officially label it that way.
No. Quality Score as a 1-10 metric is only available for Search campaigns. Display campaigns use a different relevance scoring system, and Shopping campaigns use product data quality and bid competitiveness instead of keyword-level Quality Score. However, the same principles — relevance, landing page experience, and expected engagement — apply across all campaign types.
Does pausing a keyword reset its Quality Score?
Pausing does not reset Quality Score. When you re-enable a paused keyword, it retains its previous score. If you want a fresh start, create the keyword in a new ad group or campaign. The new keyword will start with no historical data and will be evaluated based on the new ad copy and landing page you assign to it.
What is the minimum Quality Score I should aim for?
Aim for 7+ on brand keywords and 6+ on non-brand keywords. Any keyword consistently scoring below 5 after optimization attempts should be paused or restructured. Keywords scoring 8-10 represent your best-performing ad group structures and should be used as templates when building new campaigns.
