Click-Through Rate Calculator
Click-through rate (CTR) measures the percentage of people who click on a link, ad, or email after being exposed to it. It is one of the most widely tracked metrics across digital marketing, advertising, and SEO. In paid search, a high CTR signals strong ad-to-keyword relevance and can improve Quality Scores, reducing your cost per click. In SEO, CTR from organic search results reflects the quality of your title and meta description. In email marketing, CTR measures link engagement relative to list size. This calculator computes CTR from impressions and clicks, plus estimated clicks needed to reach a CTR target and projected clicks at a given volume.
CTR formula
CTR = (Clicks / Impressions) * 100
Clicks Needed = Impressions * (Target CTR / 100)
CTR Gap = Target CTR - Actual CTR
