Quality Score is a measure used primarily in paid advertising (e.g., Google Ads) to evaluate the relevance and quality of ads, keywords, and landing pages.
Higher scores can lead to better ad placement and lower costs per click (CPC). The score is based on factors such as expected click-through rate (CTR), ad relevance, and the landing page experience.
Example
An advertiser with a high-quality, relevant ad for “running shoes” that directs users to a well-designed, relevant landing page will receive a better Quality Score than an irrelevant ad or one with poor user experience.
