Key Takeaways
- Quality Score is a 1–10 rating Google assigns to each keyword in your Google Ads account, reflecting the overall quality of your ads, keywords, and landing pages.
- The three components are Expected CTR, Ad Relevance, and Landing Page Experience — each rated Above Average, Average, or Below Average.
- Higher Quality Scores directly reduce your cost per click (CPC) and improve ad position through the Ad Rank formula.
- The most impactful improvements come from tighter keyword-to-ad relevance and landing page optimization.
- A Quality Score of 7+ is considered good, 8–10 is excellent, and below 5 indicates significant issues that need fixing.
What Is Quality Score?
Quality Score is Google's 1–10 assessment of the quality and relevance of your keywords, ads, and landing pages. It is displayed at the keyword level in your Google Ads account and serves as a diagnostic tool to understand how your ad experience compares to other advertisers.
Quality Score is not directly used in the ad auction. Instead, Google uses real-time, auction-specific calculations of the same underlying factors. However, Quality Score serves as an aggregate indicator of those factors, making it the best tool advertisers have for diagnosing and improving ad quality.
The 3 Components of Quality Score
1. Expected Click-Through Rate (Expected CTR)
This predicts how likely your ad is to be clicked when shown for the keyword. It is based on the historical CTR of your ad and keyword, normalized for factors like ad position and extensions. Expected CTR reflects how compelling your ad is compared to competitors.
2. Ad Relevance
This measures how closely your ad copy matches the intent behind the keyword. If someone searches "blue running shoes" and your ad headline says "Buy Running Shoes — Blue, Red, Green Available," the ad relevance is high. If your ad says "Athletic Footwear Store," the relevance is lower.
3. Landing Page Experience
This evaluates how relevant, transparent, and easy-to-navigate your landing page is for someone who clicked your ad. Factors include content relevance to the keyword, page load speed, mobile-friendliness, and the overall user experience.
| Component | Rating Options | What Drives It |
|---|---|---|
| Expected CTR | Above Average / Average / Below Average | Historical CTR, ad copy quality, keyword match |
| Ad Relevance | Above Average / Average / Below Average | Keyword-to-ad copy alignment |
| Landing Page Experience | Above Average / Average / Below Average | Page relevance, speed, mobile UX, content quality |

Quality Score impacts two critical aspects of your campaigns:
Ad Rank
Ad Rank determines your ad position and whether your ad is shown at all. The formula is:
This means an advertiser with a $3 bid and Quality Score of 8 (Ad Rank = 24) outranks an advertiser with a $5 bid and Quality Score of 4 (Ad Rank = 20).
Cost Per Click
Higher Quality Scores directly lower your CPC. Google rewards quality with discounts:
| Quality Score | CPC Adjustment (approximate) |
|---|---|
| 10 | 50% discount |
| 8 | 25% discount |
| 7 | No adjustment (baseline) |
| 5 | 25% premium |
| 3 | 67% premium |
| 1 | 400% premium |
The math is clear: improving Quality Score from 5 to 8 can reduce your CPC by roughly 40%, meaning the same budget buys significantly more clicks.
8 Strategies to Improve Quality Score
1. Tighten Ad Group Structure
Create tightly themed ad groups with 5–15 closely related keywords. This allows you to write ad copy that is directly relevant to every keyword in the group, improving both Ad Relevance and Expected CTR.
2. Use the Keyword in Your Headline
Include the primary keyword (or a close variant) in at least one responsive search ad headline. This directly improves Ad Relevance and often increases CTR.
3. Write Compelling Ad Copy
Focus on benefits, include a clear CTA, and differentiate from competitors. Test multiple headline and description combinations — Google's responsive search ads will optimize for the best performers.
4. Use All Ad Extensions
Sitelinks, callouts, structured snippets, and other extensions increase your ad's real estate and CTR. Higher CTR improves Expected CTR, which improves Quality Score.
5. Optimize Landing Page Relevance
Ensure the landing page content directly relates to the keyword and ad copy. If your ad promotes "blue running shoes," the landing page should be about blue running shoes — not a general shoe catalog.
6. Improve Landing Page Speed
Landing page load time is a component of Landing Page Experience. Follow Core Web Vitals best practices: LCP under 2.5 seconds, minimal layout shifts, and fast interactivity.
7. Add Negative Keywords
Negative keywords prevent your ads from showing for irrelevant searches. This improves CTR (by eliminating irrelevant impressions) and ensures your traffic is qualified.
8. Monitor and Test Continuously
Use tools like Sentinel's Google Ads Clicker Bot to analyze paid search performance patterns. Regular monitoring and testing ensure your campaigns stay optimized as competition evolves.
Frequently Asked Questions
A Quality Score of 7 or above is generally considered good. Scores of 8–10 are excellent and indicate your ads, keywords, and landing pages are well-aligned. Scores below 5 suggest significant issues with relevance, CTR, or landing page experience that need immediate attention.
Quality Score is calculated based on three components: Expected Click-Through Rate (how likely your ad is to be clicked), Ad Relevance (how closely your ad matches the keyword intent), and Landing Page Experience (how relevant and user-friendly your landing page is). Each component is rated as Above Average, Average, or Below Average.
Yes. Higher Quality Scores directly reduce your cost per click. Google uses Quality Score in the Ad Rank calculation, and a higher Ad Rank with the same bid means a lower actual CPC. Improving Quality Score from 5 to 8 can reduce CPC by approximately 40%.
