Quality Score is a Google metric which estimates the quality of your ads, keywords, and landing pages. Google ranks Quality Score on a scale of 1-10 (with 10 being the highest). Higher Quality Scores can lead to better ad positions and lower costs-per-click (CPC). Quality Scores are measured in terms of relevance: the more relevant your ads and landing pages are to the user’s search intent, the more likely you will have a higher Quality Score.
