What Engagement Rate means

Engagement rate measures the level of audience interaction with an ad, calculated as total engagements (likes, comments, shares, saves, clicks) divided by impressions or reach. High engagement rates generally indicate content relevance and audience resonance. From a compliance perspective, engagement metrics can signal both positive and negative patterns — high engagement driven by controversial or sensational content may indicate policy-adjacent material that attracts attention but risks enforcement. Platforms use engagement signals as inputs for ad quality and relevance scores, which affect delivery and cost. Negative engagement (ad hides, 'not interested' clicks, reports) is weighted heavily in platform algorithms and can indicate compliance issues. Monitoring the type of engagement (positive vs. negative) alongside the rate provides more actionable compliance insights than the rate alone.
