Quality Score

What is Quality Score?

Quality Score is a metric where search engines evaluate how relevant and useful ads are to user queries on a 1-10 scale. Developed by Google Ads, this metric significantly impacts ad cost-per-click and placement rank. Higher scores indicate better ad relevance and quality, earning better display conditions.

In a nutshell: Search engines “grade” whether “this ad really matches what users want”—like school report cards. 1-10 scoring, and higher scores create advantages.

Key points:

• What it does: Quantifies ad-to-user-need matching degree
• Why it matters: Higher scores mean acquiring more clicks with smaller budgets
• Who uses it: Google Ads, Microsoft Advertising, and other search ad operators

Why it matters

Low Quality Scores require paying higher bids than competitors for same keywords. Conversely, high scores enable better placement with lower bids. Quality Score improvements directly translate to cost savings. Additionally, similar to Quality Assurance principles, delivering truly valuable relevant ads to users matters. High relevance builds long-term brand trust.

How it works

Quality Score calculation involves multiple factors. First, expected click-through rate (CTR) estimated from historical data. Second, ad relevance—whether user-searched words match ad titles and descriptions. Third, landing page quality—does the post-click webpage excel in speed, mobile compatibility, and user value?

Google’s algorithm weights and integrates these factors, generating 1-10 scores. Most critical is matching “what users want” with “what ads provide.” Like how shopping mall navigation changes based on store visibility, ad relevance directly impacts user experience.

Calculation method

Quality Score calculation uses weighted averages from multiple factors. While Google doesn’t publish exact algorithms, basic calculation resembles:

Estimated formula: Quality Score = (Expected CTR × Weight1 + Ad Relevance × Weight2 + Landing Page Quality × Weight3) / Total Weight

Example scenario:

• Expected CTR: 8/10, weight: 40%
• Ad Relevance: 7/10, weight: 35%
• Landing Page Quality: 9/10, weight: 25%

Calculation: (8 × 0.4) + (7 × 0.35) + (9 × 0.25) = 3.2 + 2.45 + 2.25 = 7.9 ≈ Quality Score: 8/10

Benchmarks

Quality Score guidelines follow:

Industry benchmark examples:

• Finance/Insurance: Average 6.5-7.5
• Medical/Health: Average 7.0-8.0
• Retail/E-commerce: Average 6.0-7.0
• B2B/SaaS: Average 7.0-7.5
• Real Estate: Average 5.5-6.5

Real-world use cases

E-commerce product ads

For “women’s running shoes” searchers, display relevant product page ads. High scores increase daily clicks while reducing cost-per-click.

Local business advertising

Dental offices display ads for “〇〇 station dentist” searchers with office information pages. Higher relevance from location and services increases scores.

B2B service ads

Cloud storage providers display implementation case study pages for “enterprise file sharing” searchers.

Benefits and considerations

Benefits include guaranteed cost reduction from Quality Score improvement. Raising one point drops cost-per-click 5-15%. Also, showing relevant ads builds long-term brand trust. A consideration is Quality Scores are relative metrics—competitor improvements can drop your score despite unchanged score. Also, high scores don’t guarantee high conversion rates; landing page persuasiveness and offer appeal require improvement too.
