Quality Score

Quality Score is a metric used in online advertising platforms, such as Google Ads, to evaluate the quality and relevance of ads, keywords, and landing pages. It plays a crucial role in determining ad placement and cost-per-click (CPC) in pay-per-click (PPC) campaigns. Essentially, it assesses how well an ad aligns with the user’s search intent and overall user experience.

TL;DR What is Quality Score?

Quality Score is a rating system used by advertising platforms to measure the relevance and quality of ads, keywords, and landing pages in PPC campaigns, influencing ad placement and cost.


Quality Score holds significant importance in the realm of online advertising and marketing strategies. It directly impacts the effectiveness and cost-efficiency of PPC campaigns. A high Quality Score can lead to lower CPCs and higher ad placements, resulting in better visibility and more clicks. Moreover, it ensures that users are presented with relevant and valuable ads, enhancing their overall experience and increasing the likelihood of conversions.

Examples/Use Cases

  • A company running a Google Ads campaign for its new product focuses on optimizing its ad copy, keywords, and landing page to improve Quality Score. As a result, they experience a decrease in CPC and an increase in conversions.
  • An e-commerce retailer enhances the relevance of its ads by aligning them with specific product categories and utilizing targeted keywords. This leads to higher Quality Scores and improved ad performance.
