Quality Score

Google's rating (1-10) of your ad's relevance to keywords and landing pages.

Quick Answer

What is Quality Score in Google Ads? Quality Score is Google's 1-10 rating of your keyword and ad relevance. Higher scores (7+) lower your cost per click by 30-50% and improve ad positions. It's calculated from expected CTR, ad relevance, and landing page experience.

What is Quality Score?

Quality Score is Google's estimate of the quality of your ads, keywords, and landing pages on a scale of 1 to 10. According to Google, "higher quality ads can lead to lower prices and better ad positions."

Quality Score directly impacts your ad rank and cost per click. A higher Quality Score (7-10) allows you to achieve better ad positions at lower costs, while a low Quality Score (1-4) forces you to bid significantly higher to maintain visibility—if your ads are eligible to show at all.

The metric is calculated using three primary factors: expected click-through rate (CTR), ad relevance, and landing page experience. Each component is rated as "Below average," "Average," or "Above average" compared to other advertisers competing for the same keyword.

Why Quality Score Matters

Quality Score is the single most important metric for controlling Google Ads costs. An increase from 5 to 7 can reduce your cost per click by 28%, while a drop from 7 to 5 increases costs by 40%.

Beyond cost savings, Quality Score impacts your competitive position. High-Quality Score advertisers can outrank competitors bidding 2-3x higher, creating a sustainable competitive advantage that compounds over time.

Common Mistakes to Avoid

Ignoring landing page experience (worth 40% of Quality Score)

Using broad match without negative keywords (destroys relevance)

Writing generic ad copy that doesn't match search intent

Sending all keywords to homepage instead of specific landing pages

Obsessing over 10/10 scores instead of focusing on 7+ consistently

Best Practices for Quality Score

Include target keyword in headline, description, and display URL

Create tightly themed ad groups (5-15 related keywords)

Write landing page headlines that match ad headlines

Test 3-4 ad variations per ad group using RSAs

Monitor "Search Terms" report weekly and add negative keywords
