The Definition of Quality Score [In Under 100 Words]

Quality Score is a metric Google uses to determine your page ranking and how much you pay per click in a particular Google AdWords campaign.

Quality Scores are essentially a measure of relevance; more relevant ads, campaigns, and landing pages have higher clickthrough rates (CTRs), which raises your Quality Score.

Google ranks Quality Score on a scale of 1-10 (with 10 being the best). Higher Quality Scores tend to lead to lower costs-per-click (CPC), which translate into lower costs per conversion.

In other words, optimizing for Quality Score also helps you optimize for costs and ROI.
