CTR, short for Click-Through Rate, measures the percentage of people who clicked on a link or CTA after seeing it. It’s calculated as (clicks ÷ impressions) × 100, and is a key indicator of how relevant and engaging your content or ad is to its audience.
A high CTR generally signals that your messaging and targeting are well-aligned. A low CTR is a prompt to revisit the creative, the audience, or the offer itself.
