Quality Score

Quality Score is a Google Ads metric rated from 1 to 10 that estimates the quality and relevance of your keywords, ads, and landing pages. It is determined by three core components: expected click-through rate, ad relevance, and landing page experience. Each component is rated above average, average, or below average, giving advertisers a clear diagnostic framework for improvement. Why it matters: Quality Score is one of the most powerful levers in pay-per-click advertising because it directly influences both your cost per click and your ad position. Google rewards advertisers who provide relevant, high-quality experiences by charging them less per click and placing their ads higher on the page. A keyword with a Quality Score of 8 or above can pay 30 to 50 percent less per click than the same keyword with a score of 4, meaning budget efficiency improves dramatically without spending an additional dollar. Conversely, low Quality Scores inflate costs and can prevent ads from showing entirely. To improve Quality Score, start by ensuring tight alignment between your keywords, ad copy, and landing page content so that the user experience feels seamless from search to conversion. Write compelling, keyword-relevant ad copy that drives higher click-through rates, and optimize landing pages for speed, relevance, and clear calls to action. Reviewing Quality Scores at the keyword level on a regular basis helps identify underperforming areas before they drain budget.
