The Three Diagnostic Metrics
Quality Ranking measures perceived quality based on feedback signals (hides, reports, post-engagement). Engagement Rate Ranking measures expected engagement rate (likes, comments, shares, clicks) compared to ads targeting the same audience. Conversion Rate Ranking measures expected conversion rate compared to ads with the same optimization goal. Each metric is rated as Above Average, Average, or Below Average. Understanding which specific metric is lagging tells you exactly where to focus your optimization efforts.
