Relevance Score

What Relevance Score means

Relevance score (called Quality Score in Google Ads, Ad Relevance Diagnostics in Meta, and similar names on other platforms) is a metric that measures how well an ad matches its target audience based on engagement signals, expected click-through rate, and landing page experience. Higher relevance scores typically result in lower costs and better ad placement. From a compliance perspective, relevance scores can be an early warning system — declining scores may indicate that ad content or targeting is misaligned, which could also signal compliance issues. Ads that generate negative feedback (hides, reports) receive lower relevance scores, and persistently low scores may trigger additional review. Optimizing relevance score through compliant, high-quality creative and accurate targeting creates a positive feedback loop between performance and compliance.
