In digital advertising, particularly within Google Ads, Quality Score is a metric that assesses the relevance and quality of ads, keywords, and landing pages. It ranges from 1 to 10 and influences how ad placements are determined and the cost-per-click (CPC). Remember, a higher Quality Score can lead to better ad positions at lower costs. The score considers factors like click-through rate (CTR), keyword relevance, and the user experience on the landing page. Optimizing these elements improves ad performance and helps businesses achieve a better return on ad spend (ROAS).
