What is CTR (Click-Through Rate)?
TL;DR: CTR is the percentage of people who click a link or CTA compared to the total who saw it. Formula: (clicks ÷ impressions) × 100. It measures how effectively your content drives action beyond passive viewing.
Good CTR varies by context: email marketing 2-5%, social media ads 0.5-2%, organic social posts 1-3%, Google Ads 3-5%. Higher CTR means your messaging, targeting, and CTA are working.
