Google Ads Quality Score: How to Improve It and Reduce Your CPC
Quality Score is the most misunderstood metric in Google Ads.
Most Australian businesses think it’s a vanity metric — a score out of 10 that Google gives them for being nice. That’s wrong.
Quality Score drives your actual cost per click (CPC) and ad position. A Quality Score of 9 can give you 30–50% lower CPC than a Quality Score of 5 — on the exact same keyword, in the same auction.
Yet most agencies ignore Quality Score. They’re wrong. Fixing Quality Score is the highest-leverage optimisation in Google Ads.
This guide breaks down exactly what Quality Score is, why it matters, and the systematic steps to improve it.
What Quality Score Actually Is
Quality Score is Google’s rating of your ad and landing page. It’s scored 1–10 for each keyword in your account.
Google rates three factors:
1. Expected Click-Through Rate (CTR)
- How likely is someone to click your ad when they see it?
- Google predicts this based on historical data for that keyword
2. Ad Relevance
- Does your ad match the search query and keyword?
- Are your headlines and descriptions talking about what they searched for?
3. Landing Page Experience
- Is your landing page fast, mobile-friendly, and relevant?
- Does it match the promise in your ad?
Each factor is rated:
- Average
- Above Average
- Below Average
Your overall Quality Score (1–10) is determined by these three.
Why Quality Score Matters (It’s Not Vanity)
Quality Score Affects Your CPC
Google uses Quality Score to calculate Ad Rank. Higher Ad Rank = higher position at lower cost.
The formula:
Ad Rank = (Maximum Bid) × (Quality Score + Other Factors)
Two advertisers, same keyword, same maximum bid. One has Quality Score 9, one has Quality Score 5.
- Advertiser A: Max bid $2.00 × Quality Score 9 = Ad Rank 18
- Advertiser B: Max bid $2.00 × Quality Score 5 = Ad Rank 10
Advertiser A shows in position 1. Advertiser B shows in position 3 or lower.
But here’s the kicker: To show in position 1, Advertiser B needs a higher maximum bid. Google charges both your actual CPC based on what the ad below you is willing to pay.
Result: Advertiser B pays $1.50 CPC (or more) while Advertiser A pays $0.80 CPC.
Same keyword, same intent, different QS = 50–80% difference in CPC.
Quality Score Affects Ad Position
Higher Ad Rank = higher position = more clicks = more conversions.
If you improve Quality Score from 5 to 9, you move from position 3 to position 1. Position 1 gets 30–50% more clicks than position 3.
Quality Score Affects Conversion Rate
Position 1 ads have higher conversion rates because they appear above competitors and look more trustworthy.
Moving from position 3 to position 1 can increase conversion rate by 20–40%.
Expected Click-Through Rate: The Biggest Factor
Expected CTR is how likely someone is to click your ad.
Google bases this on historical data:
- How often did people click your ad for this keyword in the past?
- How does that compare to other ads for the same keyword?
If your Expected CTR is “Below Average,” it means your ad doesn’t match the keyword as well as competitors’ ads.
How to Improve Expected CTR
1. Match the keyword in your headline
Google rewards ads where the searched keyword appears in Headline 1.
Keyword: “Google Ads management Australia”
Weak ad:
- Headline 1: “PPC Services”
- (Keyword not in headline)
Strong ad:
- Headline 1: “Google Ads Management Australia”
- (Keyword in headline, exact match)
When someone searches “Google Ads management Australia” and they see “Google Ads Management Australia” in your headline, it signals relevance. Higher CTR.
2. Use numbers and specificity
Specific claims outperform vague ones.
Weak: “We increase your conversion rate” Strong: “Increase Your Conversion Rate by 35%”
Numbers stop the eye. They’re memorable. Higher CTR.
3. Address objections in your headlines
Weak: “Google Ads Services” Strong: “Google Ads Management — No Setup Fees”
“No Setup Fees” removes a barrier. Higher CTR.
4. Test multiple headlines (Responsive Search Ads)
Use Google’s Responsive Search Ads (RSAs). Upload 3 headlines, 2 descriptions. Google tests combinations and learns which ones have highest CTR.
Over 2–3 weeks, your Expected CTR will improve as Google rotates toward winning combinations.
5. Differentiate from competitors
All your competitors say “expert team,” “proven results,” “affordable.”
Stand out:
Weak: “Proven Google Ads Results” Strong: “Save $500/Month on Wasted Google Ads Spend”
Be specific. Be different. Higher CTR.
Ad Relevance: Does Your Ad Match the Keyword?
Ad Relevance measures whether your ad copy matches the keyword intent.
Keyword: “google ads cost” Weak ad: “Affordable Digital Marketing Services” (Doesn’t address cost — too generic)
Strong ad: “Google Ads Cost Australia — What to Budget + ROI Calculator” (Directly addresses what they searched for)
How to Improve Ad Relevance
1. One ad group = one theme
Don’t lump random keywords into one ad group.
Bad structure:
- Ad Group: “Google Ads”
- Keywords: google ads, google ads cost, google ads australia, how to set up google ads, google ads vs facebook ads
- (All different intents, one generic ad)
Good structure:
- Ad Group: “Google Ads Cost”
- Keywords: google ads cost, google ads price, google ads pricing, average google ads cost
- (Single intent, focused ad)
- Ad Group: “Google Ads Setup”
- Keywords: how to set up google ads, google ads account setup, google ads setup guide
- (Different intent, targeted ad)
Each ad group should trigger focused, relevant ads.
2. Use keyword insertion (carefully)
Dynamic keyword insertion (DKI) automatically inserts the searched keyword into your ad.
Headline: “{KeyWord} Australia”
When someone searches “Google Ads cost Australia,” they see: “Google Ads cost Australia”
This signals relevance. Higher Ad Relevance rating.
Use DKI for Headline 1 only (multiple headline variants or single DKI headline, not both).
3. Make your description match the keyword
If your ad group is about pricing, your description should talk about pricing.
Keyword: “google ads cost”
Weak description: “Learn about digital marketing” (Doesn’t address cost)
Strong description: “See what Google Ads really costs. Free calculator included. Get a custom quote.” (Directly relevant to the keyword)
4. Negative keywords for tighter relevance
If your ad group is about cost, add “free” as a negative keyword. Someone searching “free google ads” isn’t serious about paying (low intent anyway, but it dilutes your Ad Relevance score).
Landing Page Experience: The Underrated Factor
Landing Page Experience rates how relevant and useful your landing page is.
Google checks:
- Relevance: Does the page match the ad promise?
- Speed: Does it load fast?
- Mobile: Does it work on phones?
- Trust signals: Testimonials, certifications, privacy policy, contact info
How to Improve Landing Page Experience
1. Match the ad promise
Ad: “Free Google Ads Audit” Landing page: Should have a form claiming the free audit (not your homepage, not a generic services page)
Mismatch = Below Average Landing Page Experience.
2. Fast loading speed
Google measures Core Web Vitals:
- Largest Contentful Paint (LCP): How fast does the main content load? (Target: <2.5 seconds)
- First Input Delay (FID): How fast does the page respond to clicks? (Target: <100ms)
- Cumulative Layout Shift (CLS): Does content move around as you scroll? (Target: <0.1)
If your page is slow, Google rates it Below Average.
How to check: Google PageSpeed Insights (free). Plug in your URL. It shows speed scores and issues.
Quick fixes:
- Compress images (use TinyPNG for free)
- Minify CSS and JavaScript
- Use a Content Delivery Network (CDN) like Cloudflare (free)
- Remove heavy plugins or scripts
3. Mobile optimisation
Over 60% of Google Ads traffic is mobile. If your page doesn’t work on mobile, your Landing Page Experience suffers.
Check:
- Is the form easy to fill on a phone? (Big buttons, not too many fields)
- Does text resize properly? (Not tiny)
- Can you tap CTA easily without hitting other buttons?
- Does page load fast on 4G (not just home WiFi)?
Use Google’s Mobile-Friendly Test (free) to check.
4. Trust signals
Google looks for reasons to trust your business:
- Testimonials — Real customer quotes or video reviews
- Social proof — “100+ customers,” “4.8 stars”
- Privacy policy — Visible link in footer
- Contact info — Address, phone, email
- About page — Who are you? How long have you been in business?
- SSL certificate — Is your site HTTPS? (If not, fix this immediately)
5. Relevance between ad and landing page
Ad says: “Get a free Google Ads audit in 10 minutes” Landing page: Generic service page with vague description
Mismatch. Below Average rating.
Better: Landing page has a form specifically for the Google Ads audit, promises results in 10 minutes, shows what they’ll get (report on wasted spend, cost per lead, recommendations).
Quality Score by the Numbers: What’s Good?
| Quality Score | Performance | Meaning |
|---|---|---|
| 9–10 | Excellent | Above-average CTR, relevance, and page experience. Lowest CPC, highest ad position |
| 7–8 | Good | Average or slightly above. Good CPC and position |
| 5–6 | Below Average | Below-average on one factor. Higher CPC, lower position |
| 3–4 | Poor | Below-average on multiple factors. High CPC, low position |
| 1–2 | Very Poor | Severe issues. Very high CPC, often low ad position |
Realistic Australian targets:
For competitive keywords (finance, legal, home services): 6–7 is respectable. 8+ is exceptional.
For less competitive keywords (specialist niches): 7–8 is normal. 9–10 is possible.
Systematic Approach to Improving Quality Score
Week 1: Audit
- Go to Google Ads > Keywords (in the left menu)
- Click the “Status” column to see Quality Scores
- Sort by Quality Score (lowest first)
- Identify keywords with Quality Score <6
For each low-QS keyword, check:
- What’s the Expected CTR status? (Above/average/below?)
- What’s the Ad Relevance status?
- What’s the Landing Page Experience status?
This tells you what to fix.
Week 2: Fix Ad Groups
For keywords with Below Average Expected CTR:
- Review the ad copy
- Add the keyword to Headline 1
- Use Responsive Search Ads with multiple headlines
- Ensure the ad directly addresses the keyword intent
For keywords with Below Average Ad Relevance:
- Move keyword to a more relevant ad group
- Or rewrite the ad to focus on the keyword’s intent
- Add related keywords to the same ad group (same intent)
For keywords with Below Average Landing Page Experience:
- Check page speed (PageSpeed Insights)
- Check mobile optimisation (Mobile-Friendly Test)
- Ensure landing page matches the ad promise
- Add trust signals (testimonials, reviews, security badges)
Week 3: Test and Monitor
- Apply changes
- Wait 2 weeks for Quality Scores to update (Google needs time to see if clicks improve)
- Monitor movement: Are scores improving?
- Repeat for next batch of low-QS keywords
Quality Score Myths (Debunked)
Myth 1: Quality Score is a ranking factor for organic search
False. Quality Score only affects paid ads. It has zero impact on your organic rankings.
Myth 2: Quality Score = Ad Rank
False. Quality Score is one component of Ad Rank. Ad Rank = Max Bid × Quality Score + Other Factors (audience size, device, location, etc.).
Myth 3: High Quality Score = High conversions
False. Quality Score measures CTR and relevance. A high-CTR ad might not convert well if the landing page is bad.
Example: An ad with great copy (high CTR) sends traffic to a poorly optimised landing page. High QS, low conversion rate.
Myth 4: I should focus on Quality Score over conversions
Wrong priority. Focus on conversions and profitability first. Quality Score is a lever to improve CPC, which improves profitability.
If improving QS lowers your CTR (you remove a strong benefit claim to insert the keyword), don’t do it.
Common Quality Score Mistakes
1. Ignoring Expected CTR
You focus on landing page experience but ignore the fact your ad copy doesn’t match the keyword. Expected CTR stays Below Average. Fix your ad copy.
2. Multiple ad groups with same keyword
You have “Google Ads” as a keyword in Ad Group A (about setup) and Ad Group B (about cost). Google gets confused about which ad is most relevant.
Solution: One keyword should live in one ad group. Delete duplicates.
3. Slow landing pages
You fix ad copy and ad relevance, but your landing page loads in 5 seconds. Google rates it Below Average.
Speed matters. Fix it.
4. Mobile-unfriendly pages
60% of traffic is mobile. If your page is desktop-only, Landing Page Experience suffers.
Test on mobile. Fix issues.
5. Weak landing page relevance
Ad says “Free audit.” Landing page is your homepage. Below Average rating.
Send traffic to a page specifically about the offer.
The Bottom Line on Quality Score
Quality Score isn’t vanity. It’s a direct lever on your CPC and profitability.
Improving Quality Score from 5 to 8 can reduce your CPC by 40–50%. On a $10,000/month ad spend, that’s $4,000–$5,000 in pure savings.
The effort: rewrite ad copy, fix landing pages, ensure speed and mobile optimisation.
Time investment: 5–10 hours for a mature account.
Return: thousands in saved spend or redirect that savings to volume.
