Your Quality Score is a 1–10 number that determines whether you pay $0.50 or $5 for the same click.
Improve it from 5 to 8, and you'll cut your CPC in half. Yet 70% of advertisers ignore Quality Score entirely. It's the fastest ROI multiplier available.
What Quality Score Measures
Google grades three components: expected click-through rate (CTR), ad relevance, and landing page experience. Each gets a rating (average or above average). Quality Score is the combination.
