Quality Score
The Quality Score is an index used by Google Ads to determine the quality and relevance of ads, keywords, and landing pages.
This metric is a numeric index, ranging from 1 to 10, and is determined by several factors, including click-through rate (CTR), ad text relevance, landing page quality and relevance, and historical account performance. A high score can lead to lower cost per click (CPC) and better ad placement.
