Google Ads operates like an auction where advertisers bid on keywords relevant to their products or services. But here’s what many business owners don’t realise: the highest bidder doesn’t always win. Google considers ad quality and relevance alongside bid amounts, making Quality Score one of the most important factors in your campaign success.
If your ads aren’t delivering the results you need, poor Quality Scores could be holding you back. Understanding how Quality Score and Ad Rank work together is essential for maximising your ad spend and driving more conversions. At PWD Digital Agency, we’ve seen businesses slash their cost-per-click while improving ad positions simply by focusing on these fundamentals.
What is Google Ads Quality Score?
Quality Score is Google’s rating system that measures the quality and relevance of your keywords and ads on a scale from 1 to 10. Think of it as Google’s way of determining whether your ad provides value to users searching for specific terms.
The Quality Score formula considers three main components:
Click-Through Rate (CTR)
Your CTR shows how often people click your ad after seeing it. A high CTR signals that users find your ads relevant and compelling. Google rewards this engagement with better Quality Scores because it indicates your ad meets user expectations.
Ad Relevance
Google evaluates how closely your ad copy matches the intent behind the keywords you’re bidding on. Your ad text should directly relate to your target keywords and ad groups. Irrelevant ad copy will drag down your scores regardless of how much you bid.
Landing Page Experience
Your landing page must deliver on the promise made in your ad. Google assesses page loading speed, mobile-friendliness, content relevance, and overall user experience. A poor landing page will hurt your Quality Score even if your ads are perfectly crafted.
How Ad Rank Determines Your Success
Ad Rank is the metric that actually determines where your ads appear in search results. It combines your Quality Score with your maximum cost-per-click (CPC) bid using this formula:
Ad Rank = Quality Score × Max CPC Bid
When multiple advertisers target the same keywords, Google ranks ads by their Ad Rank scores. The advertiser with the highest Ad Rank gets the top position, followed by the second-highest, and so on.
This system means you can outrank competitors who bid more than you by achieving better Quality Scores. We’ve helped clients secure top ad positions while paying less per click than competitors with lower-quality campaigns.
How Ad Rank Affects Your Costs
Your actual CPC isn’t what you bid – it’s calculated based on your competitors’ Ad Rank. The formula is:
Actual CPC = (Ad Rank of competitor below you ÷ Your Quality Score) + $0.01
This means improving your Quality Score directly reduces what you pay per click. A campaign with a Quality Score of 8 will pay less than an identical campaign with a Quality Score of 4, even with the same bid amount.
How to Check Your Quality Score
Monitoring your Quality Scores regularly helps identify opportunities for improvement. Here’s how to find your scores in Google Ads:
- Log into your Google Ads account
- Click on ‘Campaigns’ in the left menu
- Select the ‘Keywords’ tab
- Look for the Status column and hover over the speech bubble icon
You’ll see your Quality Score along with ratings for each component (Expected CTR, Ad Relevance, and Landing Page Experience). These ratings appear as “Above Average,” “Average,” or “Below Average.”
Focus on keywords with Quality Scores below 7. These represent your biggest opportunities for improvement and cost savings.
Proven Strategies to Improve Your Quality Score
Improving Quality Scores requires a systematic approach across your entire campaign structure. These strategies have consistently delivered results for our clients at PWD Digital Agency.
Create Tightly Focused Ad Groups
Relevance starts with proper campaign structure. Keep your ad groups small and focused, with 15-20 closely related keywords maximum. When your keywords are tightly themed, you can write more relevant ad copy that speaks directly to user intent.
For example, instead of one ad group containing “plumber,” “emergency plumber,” and “blocked drain repair,” create separate ad groups for each service. This allows for more targeted messaging and better Quality Scores across all keywords.

Remove irrelevant keywords that drag down your scores. Review your search terms report monthly to identify queries that aren’t converting or aren’t relevant to your business. Add these as negative keywords to prevent your ads from showing for these searches.
Also consider match types carefully. Broad match keywords often trigger irrelevant searches, hurting your CTR and Quality Score. Use phrase match and exact match for better control over when your ads appear.
Write Compelling, Relevant Ad Copy
Your ad copy must include your target keywords naturally while addressing user needs. Test different headlines and descriptions to improve CTR. A higher CTR directly improves your Quality Score and reduces costs.
Include clear calls-to-action and unique selling propositions. Users should understand exactly what they’ll get by clicking your ad. For more advanced techniques, check out our guide on creating highly converting ad copy.
Optimise Your Landing Pages
Your landing page must match the promise made in your ad. If your ad promotes “free consultation,” the landing page should prominently feature this offer. Page loading speed affects Quality Score too – aim for load times under 3 seconds.
Ensure your landing pages are mobile-friendly and provide clear paths to conversion. Include relevant keywords in your page content, but avoid keyword stuffing. Focus on user experience and value delivery. For more insights, read our post on optimising user experience.
Advanced Quality Score Optimisation
Beyond the basics, several advanced techniques can further improve your Quality Scores and campaign performance.
Use Ad Extensions Strategically
Ad extensions don’t directly impact Quality Score, but they affect Ad Rank and can improve CTR. Use sitelink extensions, callout extensions, and structured snippet extensions to make your ads more prominent and informative.
Extensions that align with user intent often improve click-through rates, which positively impacts Quality Score over time. For service businesses, location extensions and call extensions can significantly boost performance.
Implement Smart Bidding
Google’s automated bidding strategies can help optimise for better Quality Scores by adjusting bids based on likelihood to convert. Target CPA and Target ROAS bidding often lead to better Quality Scores because they focus on valuable traffic.

Common Quality Score Mistakes to Avoid
Even experienced advertisers make mistakes that hurt their Quality Scores. Avoid these common pitfalls:
- Ignoring mobile experience: More than half of searches happen on mobile devices. Poor mobile landing pages will hurt your scores significantly
- Using irrelevant keywords: Adding loosely related keywords to “catch more traffic” actually hurts your campaigns by reducing relevance
- Neglecting negative keywords: Without proper negative keywords, your ads show for irrelevant searches, reducing CTR and Quality Score
- Generic ad copy: One-size-fits-all ad copy doesn’t resonate with specific user intents, leading to lower CTRs
- Slow loading pages: Page speed directly impacts Quality Score. Optimise images and reduce server response times

Measuring Quality Score Impact on Performance
Track how Quality Score improvements affect your overall campaign performance. Key metrics to monitor include:
- Average CPC (should decrease as Quality Scores improve)
- Impression share (should increase with better Ad Rank)
- Average ad position (should improve)
- Conversion rate (often improves with better relevance)
- Cost per conversion (should decrease)
Set up conversion tracking to measure real business impact. Quality Score improvements that don’t translate to better business results may indicate issues with your conversion funnel rather than your ads. For more on tracking performance, read our post about essential digital marketing metrics.
Quality Score’s Role in Campaign Strategy
Quality Score isn’t just a metric to optimise – it should influence your entire Google Ads strategy. High-Quality Score campaigns allow you to:
- Bid more aggressively on profitable keywords
- Expand into competitive markets with lower costs
- Test new ad formats and extensions
- Allocate budget to high-performing campaigns
Consider Quality Score when planning new campaigns. Start with highly relevant, tightly focused campaigns to establish good scores, then expand gradually. This approach builds a strong foundation for long-term success.
Quality Score optimisation works best as part of a complete digital marketing strategy. Consider how your Google Ads campaigns integrate with your SEO efforts and broader digital marketing activities.
What is a good Quality Score in Google Ads?
A Quality Score of 7-10 is considered good, with 8-10 being excellent. Scores below 5 indicate significant issues that need immediate attention. Most successful campaigns maintain average Quality Scores between 7-8.
How often does Google update Quality Score?
Google updates Quality Score in real-time based on your campaign performance. However, you’ll typically see changes reflected in your account within 24-48 hours of making optimisations to your keywords, ads, or landing pages.
Can I improve Quality Score without changing my bids?
Yes, Quality Score depends on relevance and user experience, not bid amounts. You can improve scores by optimising ad copy, refining keywords, adding negative keywords, and improving landing page experience without adjusting bids.
Do paused keywords affect Quality Score?
Paused keywords retain their Quality Scores, but these scores become inactive and don’t impact your account. When you reactivate paused keywords, they start with their previous Quality Score as a baseline.
How long does it take to see Quality Score improvements?
Quality Score improvements typically take 1-2 weeks to show after making changes, depending on your campaign traffic volume. High-traffic campaigns may see changes within a few days, while low-traffic campaigns may take longer.
Does Quality Score affect Google Shopping campaigns?
No, Quality Score only applies to Search and Display campaigns. Google Shopping campaigns use different ranking factors including product feed quality, bid amounts, and merchant performance rather than traditional Quality Score metrics.
