Quality Score

What is Ad Quality Score?

Ad quality score is a core metric used by the Google Ads system to evaluate the quality of search ads, directly determining the ad’s ranking in search results and cost-per-click (CPC). It is a scoring system ranging from 1 to 10, where 10 represents the highest quality. A higher score typically allows ads to obtain:

• More prominent display positions
• Lower actual click costs
• Higher conversion rate potential

Key Components of Quality Score:

1. Ad Relevance: Measures how relevant the ad text is to the user’s search query
2. Click-through Rate (CTR): The frequency at which users click on the ad
3. Landing Page Experience: The user experience and relevance of the page after clicking

Google calculates the quality score by comprehensively considering these three factors. It is worth noting that the quality score is not a simple average but is dynamically calculated based on various algorithms, and it fluctuates with changes in keywords and account environments.

Why is Quality Score So Important?

Ad quality score has a decisive impact on the success of digital marketing campaigns:

• Directly determines ad ranking: All else being equal, ads with higher quality scores rank higher
• Significantly reduces advertising costs: High-quality ads usually enjoy Google’s ranking rewards, significantly reducing per-click expenses
• Improves overall return on investment: Lower CPC and higher click conversion rates lead to better ROI
• Enhances ad account health: Maintaining a good quality score helps the account avoid penalties such as demotion
