Quality Score is a metric used by search engines like Google to determine the relevance and quality of your ads and keywords. It is a fundamental component of search engine marketing platforms that influences both the cost and effectiveness of your pay-per-click (PPC) advertising campaigns. The score is calculated based on a combination of factors including the click-through rate (CTR), the relevance of each keyword to its ad group, landing page quality and relevance, and the overall user experience. Advertisers with higher Quality Scores can achieve higher ad placements at lower costs because their ads are deemed more relevant to users’ search queries. A high Quality Score indicates that your ad and landing page are relevant and useful to someone looking at your ad, whereas a low Quality Score suggests that your ad, keywords, or landing page may not be as relevant or as useful to the audience you’re targeting. By optimizing for Quality Score, advertisers can improve their ad rankings and lower their costs per click, thereby making their advertising efforts more efficient and cost-effective.
