Google Ads Quality Score: What It Is and How to Improve It
Quality Score is Google's 1-10 rating of the overall quality and relevance of your keywords, ads, and landing pages. It directly affects how much you pay per click and whether your ads show at all. A keyword with a Quality Score of 9 can pay 50% less per click than the same keyword with a score of 4 -- while appearing in a higher position. For every dollar you spend on Google Ads, Quality Score determines how far that dollar goes.
We manage accounts where improving Quality Score from 5 to 8 across core keywords reduced cost per lead by 35% without changing the budget. The math is that clear, and yet Quality Score remains one of the most neglected optimization levers in most Google Ads accounts.
How Quality Score Works
Quality Score is calculated at the keyword level. Every keyword in your account receives a score from 1 to 10 based on three components, each rated "Below Average," "Average," or "Above Average":
Expected Click-Through Rate (CTR)
Google predicts how likely your ad is to be clicked when shown for this keyword, compared to other advertisers bidding on the same keyword. This prediction removes the effect of ad position, extensions, and other factors that influence CTR externally -- it's an apples-to-apples comparison of ad relevance.
A high expected CTR signals that your ad is compelling and relevant to the search query. A low expected CTR tells Google that searchers are ignoring your ad, which suggests a mismatch between the keyword, the ad, and the searcher's intent.
Ad Relevance
This measures how closely your ad matches the intent behind the search query. If someone searches "emergency furnace repair" and your ad talks about "HVAC installation services," the ad relevance is low. If the ad headline reads "24/7 Emergency Furnace Repair," the relevance is high.
Ad relevance is about alignment between the keyword, the search intent, and the ad copy. Tight ad groups with closely related keywords and tailored ad copy score well. Broad ad groups stuffed with loosely related keywords and generic ads score poorly.
Landing Page Experience
Google evaluates whether your landing page delivers on the promise of the ad. Key factors include: content relevance (does the page match the ad and search query?), load speed (is the page fast, especially on mobile?), navigation (is it easy to find information?), and transparency (is there clear contact info, privacy policy, and business information?).
Landing page experience is the component that takes the most effort to improve but delivers the most durable results. A landing page that scores "Above Average" continues to benefit every keyword that points to it.
Why Quality Score Matters for Your Costs
Google Ads uses an Ad Rank formula to determine your position and cost:
Ad Rank = Maximum Bid x Quality Score (simplified)
The actual formula includes ad extensions and other factors, but the core relationship holds: higher Quality Score means higher Ad Rank at the same bid, which means better position at a lower cost.
Here is how the economics work in practice. Assume two competitors bidding on "personal injury lawyer Edmonton":
Competitor A: Max bid $50, Quality Score 4. Ad Rank = 200. Competitor B (you): Max bid $35, Quality Score 8. Ad Rank = 280.
You win the higher position despite bidding $15 less per click. Google rewards relevance because relevant ads create a better search experience, which keeps users coming back to Google. The incentive is structural.
Over a month with 500 clicks, that $15/click difference translates to $7,500 in savings -- real money that goes back into your budget or drops to your bottom line.
How to Improve Expected Click-Through Rate
Write Ads That Mirror the Search Query
The single most effective CTR improvement is including the keyword (or a close variant) in the headline. Searchers scan results for exact matches to their query. An ad that reflects their exact words earns the click.
For "furnace repair Edmonton," the headline should include both "furnace repair" and "Edmonton." Not "HVAC Services" or "Home Heating Solutions." Direct, specific, and match the language the searcher used.
Use All Available Ad Extensions
Sitelinks, callouts, structured snippets, call extensions, and location extensions increase the visual footprint of your ad and provide additional reasons to click. Google has stated that extensions improve CTR even when the extensions themselves are not clicked, because the ad appears more comprehensive and trustworthy.
We add a minimum of 4 sitelinks, 4 callouts, and 2 structured snippets to every campaign we manage. The improvement in CTR is consistent and immediate.
Test Ad Variations Aggressively
Run 3-5 responsive search ad variations per ad group. Provide 10-15 headline options and 4 description options. Pin your highest-performing headline to position 1 and let Google test combinations for the rest. Review performance every two weeks, pause low-performing assets, and replace them with new tests.
The best-performing ad in an ad group typically has 20-40% higher CTR than the worst. Ongoing testing compounds that advantage.
Use Emotional and Specific Triggers
Ads with specific numbers outperform vague claims. "Save 30% on Furnace Repair" beats "Affordable Furnace Repair." "Rated 4.9 Stars - 500+ Reviews" beats "Trusted HVAC Company." Specificity signals credibility and gives the searcher a concrete reason to click your ad over the competitor's.
How to Improve Ad Relevance
Build Tight, Themed Ad Groups
The single biggest structural mistake in Google Ads accounts is ad groups with 20-50 loosely related keywords sharing generic ad copy. The fix is SKAGs (single keyword ad groups) or tightly themed ad groups with 5-10 closely related keywords.
For a roofing company, instead of one ad group for "roofing," create separate ad groups for "roof repair," "roof replacement," "emergency roof repair," and "metal roofing." Each ad group gets ad copy tailored to that specific theme. Ad relevance scores improve immediately.
Align Ad Copy to Keyword Intent
Not all keywords have the same intent. "How much does roof repair cost" is informational -- the ad should lead with value and education. "Emergency roof repair near me" is urgent -- the ad should lead with speed and availability. "Best roofing company Edmonton" is comparison -- the ad should lead with credentials and reviews.
Writing ads that match keyword intent, not just keyword text, is what separates "Average" ad relevance from "Above Average."
Use Keyword Insertion Thoughtfully
Dynamic keyword insertion (DKI) automatically places the searched keyword into your ad headline. It improves relevance scores but can create awkward or unprofessional ads if not controlled. Use DKI with a strong default text, and exclude it from ad groups where the keyword variations could produce nonsensical headlines.
How to Improve Landing Page Experience
Build Dedicated Landing Pages
Every major keyword theme should have its own landing page. Sending all traffic to your homepage guarantees a "Below Average" landing page experience for most keywords. The homepage is designed for everyone; a landing page is designed for the exact person who clicked the exact ad for the exact keyword.
A plumber running ads for "drain cleaning" and "water heater installation" needs two separate landing pages. The drain cleaning page talks about drain cleaning, shows drain cleaning pricing, and has a drain cleaning call to action. The water heater page does the same for water heaters. This alignment between keyword, ad, and page is what Google is evaluating.
Investing in custom landing page design pays for itself through Quality Score improvement alone, before you even measure the conversion rate lift from a focused page.
Optimize Page Speed
Google measures landing page load time as part of the experience score. Target under 3 seconds on mobile. The most common speed killers: unoptimized images, render-blocking JavaScript, excessive third-party scripts (chat widgets, analytics tags, social embeds), and slow hosting.
Run your landing pages through PageSpeed Insights and fix anything scoring below 80 on mobile. The correlation between page speed and Quality Score is direct and measurable.
Ensure Mobile-First Design
Over 60% of Google searches happen on mobile devices. If your landing page requires pinching, zooming, or horizontal scrolling on a phone, Google will penalize your landing page experience score. Responsive design, tap-friendly buttons (minimum 48px), and readable text without zooming are baseline requirements.
Include Trust Signals
Google's quality raters look for E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness). On landing pages, this translates to: visible contact information, physical address, reviews and testimonials, industry certifications, clear privacy policy, and transparent pricing or next-step information. Pages that feel anonymous or lack credibility signals score lower.
Quality Score Optimization Process
Here is the process we follow for Google Ads management clients:
Week 1: Audit. Export all keywords with their Quality Score and component ratings. Sort by cost (highest spend first). The keywords consuming the most budget with below-average components are your highest-priority fixes.
Week 2-3: Ad restructuring. Break large ad groups into tighter themes. Rewrite ad copy to match keyword intent. Add extensions to every campaign.
Week 4-6: Landing page alignment. Build or modify landing pages for your top-spending keyword themes. Optimize speed and mobile experience.
Week 7-8: Measure. Quality Score updates take 1-2 weeks after changes. Compare pre and post scores. Calculate CPC changes and cost savings.
Ongoing: Test and refine. Ad copy testing, landing page A/B testing, and keyword expansion continue indefinitely. Quality Score is not a one-time fix -- it's an ongoing practice.
Common Quality Score Myths
"Quality Score doesn't matter for Smart Bidding." False. Smart Bidding strategies like Target CPA and Target ROAS still use Quality Score in the auction. Higher Quality Score gives the algorithm more room to find conversions at your target because the cost per click is lower.
"I need a 10/10 on every keyword." Unrealistic and unnecessary. Scores of 7-8 on your core keywords represent strong performance. Scores of 9-10 happen on branded terms and exact-intent matches. Focus effort on moving 4s and 5s to 7s -- that's where the cost impact is largest.
"Quality Score updates in real time." It does not. The visible Quality Score in your account is a lagging indicator based on aggregated historical performance. Changes to ads and landing pages take days to weeks to reflect in the score. Don't make changes and check the next day expecting movement.
"Low Quality Score keywords should be paused." Not always. Some keywords have low Quality Score because they're broad or competitive, but they still convert profitably. If the cost per conversion meets your targets, the keyword earns its place regardless of score. Quality Score is a cost efficiency lever, not a binary pass/fail.
The Financial Impact
Across the accounts we manage, systematic Quality Score improvement typically delivers:
- 20-40% reduction in average CPC on optimized keywords
- 15-25% increase in impression share at the same budget (lower CPCs buy more clicks)
- 10-20% improvement in conversion rate from better landing page alignment (a side effect of optimizing for landing page experience)
These compound. Lower CPCs mean more clicks. Better landing pages mean higher conversion rates. More conversions at lower cost mean you can either reduce budget or reinvest for growth. Quality Score is the closest thing to a free lunch in Google Ads -- it costs effort, not money, and the returns are measurable and durable.
If your Quality Score is stuck below 6 on your core keywords, the opportunity cost is significant. Our Google Ads team starts every new account engagement with a Quality Score audit because it's the fastest path to better economics without changing your budget.
