Google Ads Quality Score is a 1-10 rating that measures the relevance and quality of your keywords, ad copy and landing pages relative to the user’s search query. A higher Quality Score lowers your cost per click, improves your ad position and stretches your advertising budget further by rewarding advertisers who deliver relevant, useful experiences to searchers.
How Quality Score Works
Google assigns a Quality Score to each keyword in your account based on three components: expected click-through rate (CTR), ad relevance and landing page experience. Each component receives a rating of “below average,” “average” or “above average.”
Quality Score directly influences your Ad Rank, which determines your ad position and actual cost per click. The formula: Ad Rank = Max Bid x Quality Score + Expected Impact of Extensions. This means an advertiser with a $3 bid and Quality Score of 8 outranks an advertiser with a $5 bid and Quality Score of 4.
Professional PPC management focuses heavily on Quality Score optimization because it is the single biggest lever for reducing cost while maintaining or improving performance.
The Three Components of Quality Score
Expected Click-Through Rate (CTR)
This measures how likely users are to click your ad when it appears for a given keyword. Google calculates expected CTR based on your historical CTR data, adjusted for ad position, extensions and other factors.
A “below average” expected CTR means your ads are not compelling enough for the keyword you are targeting. Either the ad copy does not match the search intent or the keyword is too broad for your offering.
Ad Relevance
Ad relevance measures how closely your ad copy matches the intent behind the user’s search query. If someone searches “emergency plumber Toronto” and your ad talks about general home renovation, ad relevance will be low.
Google wants to show ads that directly address what the user is looking for. The more precisely your ad copy matches the keyword’s intent, the higher your ad relevance score.
Landing Page Experience
Landing page experience evaluates how relevant, useful and easy-to-navigate your landing page is for users who click your ad. Google considers content relevance, page load speed, mobile-friendliness and the overall user experience.
A landing page that loads slowly, does not address the keyword’s topic or provides a poor mobile experience drags down this component regardless of how good your ad copy is.
How to Improve Expected Click-Through Rate
Include Keywords in Ad Headlines
Place your target keyword in at least one headline. When users see their exact search query reflected in your ad, they are more likely to click. Use dynamic keyword insertion for ad groups with closely related keywords.
Write Compelling Ad Copy
Differentiate your ad from competitors. Include specific numbers, offers or benefits. “Save 30% on First Month” outperforms “Great Prices Available.” Use urgency when appropriate: “Limited Spots” or “Offer Ends Friday.”

Use All Available Ad Extensions
Sitelinks, callouts, structured snippets and call extensions make your ad larger and more informative. Ads with extensions receive higher CTR, which improves expected CTR over time.
Test Multiple Ad Variations
Run at least three responsive search ad variations per ad group. Test different headlines, descriptions and CTAs. Pause underperformers monthly and replace them with new variations based on what works.
How to Improve Ad Relevance
Build Tight, Themed Ad Groups
Group closely related keywords together and write ad copy specific to each group. An ad group with 50 unrelated keywords cannot serve relevant ads to all of them. Aim for 5-15 tightly related keywords per ad group.
Match Ad Copy to Search Intent
Understand whether the keyword signals informational, navigational or transactional intent. Write ad copy that matches:
- Informational: “Learn How to…” or “Complete Guide to…”
- Transactional: “Get a Quote,” “Buy Now,” “Book Today”
- Navigational: Include your brand name prominently
Use Negative Keywords
Negative keywords prevent your ads from showing for irrelevant searches. Review your search terms report weekly and add irrelevant queries as negatives. This improves ad relevance by ensuring your ads only appear for searches that match your offering.
How to Improve Landing Page Experience
Match Landing Page Content to Ad Copy
If your ad promises “Free SEO services Audit,” the landing page must prominently feature the free SEO audit offer. Mismatches between ad promises and landing page content kill both Quality Score and conversion rates.
Optimize Page Speed
Slow landing pages receive lower Quality Scores. Compress images, minimize JavaScript, enable browser caching and use a CDN. Target a page load time under 3 seconds. Google measures landing page speed as part of the experience evaluation.
Ensure Mobile Responsiveness
Over 60% of Google searches happen on mobile. If your landing page is not mobile-friendly, you lose Quality Score points and conversions. Test your landing pages on multiple devices and screen sizes.
Provide Relevant, Original Content
Your landing page should provide valuable information related to the keyword and ad. Thin pages with minimal content receive poor landing page experience scores. Include enough detail to satisfy the user’s query and guide them toward conversion.
Make Navigation Easy
Clear CTAs, logical page structure and easy access to contact information all contribute to positive landing page experience. Visitors should never struggle to find what the ad promised them.
Quality Score Monitoring and Maintenance
Check Quality Scores Weekly
Add the Quality Score column to your keyword report in Google Ads. Sort by Quality Score to identify keywords scoring below 5. These are your priority optimization targets.
Track Component Ratings
Add columns for expected CTR, ad relevance and landing page experience. These diagnostic ratings tell you exactly which component needs improvement for each keyword.
Document Changes and Results
When you make changes to improve Quality Score, document what you changed and when. Monitor the affected keywords over the following two to four weeks to measure impact. This data helps you identify which optimization tactics deliver the biggest improvements for your account.
The Financial Impact of Quality Score
Quality Score directly affects your bottom line. A keyword with a Quality Score of 10 can cost 50% less per click than the same keyword with a Quality Score of 5. Across an entire account, even a one-point average Quality Score improvement reduces cost per click by approximately 10-15%.
For a business spending $5,000 per month on Google Ads, improving average Quality Score from 5 to 7 could save $750-$1,000 per month while maintaining the same traffic volume and ad positions.
