What Is Website Quality Score?
Quality Score is Google's diagnostic tool that provides feedback on the quality and relevance of your keywords, ads, and landing pages. It operates on a scale of 1-10, with 10 being the highest possible score, and is calculated at the keyword level for Search campaigns. This score represents Google's estimation of how well your ad matches what someone searching for that keyword is looking for, compared to other advertisers.
Key takeaway: Quality Score directly influences your advertising costs through its role in the Ad Rank calculation. Higher scores mean lower costs per click and better ad positions. Improving your landing page experience is one of the most impactful ways to boost your quality score, as it affects not just ad relevance but also user satisfaction after the click.
The Three Components of Quality Score
Quality Score is composed of three distinct factors that Google evaluates for each keyword in your account. Understanding these components is essential because each requires a different optimization approach.
Each component contributes equally to your overall quality score
Expected Click-Through Rate
Measures how likely users are to click on your ad when it appears for a search query. Google calculates this based on historical performance data and how closely your keywords match the search query.
Ad Relevance
Evaluates how well your keywords align with your ad copy. When your ad text directly addresses what someone is searching for, it receives higher ad relevance ratings.
Landing Page Experience
Measures how well your landing page provides a relevant, transparent, and easy-to-navigate experience. Google evaluates page load speed, content relevance, and ease of navigation.
Understanding Your Quality Score
Quality scores range from 1 to 10, with higher numbers indicating better performance relative to advertiser competition. However, interpreting these scores requires context.

Score Interpretation Guide
-
Scores of 7-10 represent above-average performance. Keywords in this range typically enjoy lower costs per click and better ad positions.
-
Scores of 4-6 represent average performance. Most keywords in well-managed accounts fall within this range with room for incremental improvement.
-
Scores of 1-3 indicate below-average performance that warrants attention. These keywords may be costing more than necessary.
Note: Brand keywords typically achieve high scores, while competitor keywords often receive lower scores due to inherent relevance challenges.
How Quality Score Affects Your Advertising Costs
Quality Score directly impacts your advertising costs through its role in the Ad Rank calculation. Ad Rank determines whether your ad appears in the auction and in what position. The formula multiplies your quality score by your maximum bid, meaning that a higher quality score can help you achieve better ad positions even with lower bids. This relationship makes quality score optimization one of the most cost-effective strategies for paid advertising campaigns, often delivering better returns than simply increasing bids.
Best Practices to Improve Quality Score
Improving quality score requires a systematic approach addressing each of the three components. The following best practices provide actionable strategies for improvement.
Optimizing Expected Click-Through Rate
Create ads that directly address searcher intent. Use compelling calls-to-action that motivate clicks. Incorporate keywords naturally within headlines and descriptions. Test multiple ad variations to identify high-performing messaging. Use ad extensions to increase ad prominence and provide additional reasons to click.
Quick wins: Test urgency phrases, highlight unique selling propositions, and include specific benefits in your ad copy. For more on optimizing different ad formats, see our guide to PPC ad formats.
Common Quality Score Pitfalls to Avoid
Avoiding common mistakes is just as important as implementing best practices. Many advertisers inadvertently harm their quality scores through well-intentioned but misguided approaches.
Keyword Stuffing
Adding broad, loosely related keywords to capture more traffic typically backfires. Each keyword should earn its place through clear relevance to your offerings.

Neglecting ad group organization leads to systemic quality score problems. Organize into focused, manageable ad groups with tightly grouped keywords.
Disconnected Landing Pages
Driving traffic to general pages rather than dedicated landing pages for specific offers. Each campaign should have a corresponding targeted landing page.
