📖 What is Quality Score?

Quality Score is a metric used by Google Ads to determine the relevance and quality of your ads, keywords, and landing pages. It’s measured on a scale of 1 to 10, where 1 is the lowest and 10 is the highest.

A higher Quality Score indicates that your ads are relevant to users’ search queries, which can lead to lower costs and better ad placements. Google assigns this score based on historical data about how your ads have performed in the past.

🔍 Why Does Quality Score Matter?

Cost Efficiency: Higher scores often result in lower cost-per-click (CPC).
Better Ad Placement: Ads with better scores are more likely to appear in top positions.
Improved User Experience: Google rewards advertisers who create ads that resonate with their audience.

💡 Think of Quality Score as your ad’s credit score—it tells Google how reliable and relevant your ads are to users.

⚙️ How is Quality Score Calculated?

Google uses three primary components to calculate your Quality Score:

1. Expected Click-Through Rate (CTR)

This metric predicts how likely it is that users will click on your ad when it appears.

High CTR = Relevant ad copy that resonates with the audience.
Low CTR = Unappealing ad copy or mismatched keywords.

2. Ad Relevance

Ad relevance measures how closely your ad copy aligns with the intent behind users’ search queries.

High relevance = Ads that directly answer users’ needs.
Low relevance = Generic or misleading content.

3. Landing Page Experience

Google evaluates the quality and relevance of the page users land on after clicking your ad.

Positive experience = Fast load times, clear content, and mobile-friendliness.
Negative experience = Slow performance or irrelevant content.

Formula Insight:
Quality Score ≈ CTR × Ad Relevance × Landing Page Experience

🧠 How Quality Score Affects Your Campaign

🔢 1. Ad Rank and Position

Your ad’s position in search results is determined by your Ad Rank, which is calculated as:
Ad Rank = Quality Score × Maximum Bid

Higher scores can elevate your ad position without increasing your budget.
Even if a competitor bids more, a better Quality Score can secure a top spot.

💸 2. Cost-Per-Click (CPC)

Google rewards relevant and well-optimized ads with lower CPCs.

High-quality ads pay less per click.
Poorly optimized ads pay more, even if the bid is higher.

👉 A Quality Score of 10 can reduce your CPC by up to 50%, while a score of 1 can increase it by 400%.

🎯 3. Campaign ROI and Conversion Rates

A high Quality Score often correlates with more relevant traffic, higher engagement, and better conversion rates.

Users find what they’re looking for faster.
Ads reach a more interested and targeted audience.

🌐 4. Ad Extensions and Eligibility

Google Ads extensions (like sitelinks, callouts, and structured snippets) are more likely to appear for ads with better scores.

More ad real estate increases click-through rates.
Enhanced visibility boosts brand credibility.
