What is CTR?

CTR stands for "Click-Through Rate," one of the most important performance metrics in digital marketing used to measure ad attractiveness and user engagement. Higher CTR indicates the ad better attracts target audience interest and prompts clicks. CTR is a key metric for evaluating whether ad creative, copy, and audience targeting are successful, and is also an important factor in Google Ads Quality Score.

CTR Calculation Formulas

CTR calculations are straightforward. This calculator supports three different calculation methods:

1. Calculate CTR (Click-Through Rate)

CTR = (Clicks ÷ Impressions) × 100%

Example: Ad shown 10,000 times, received 500 clicks CTR = (500 ÷ 10,000) × 100% = 5%

2. Calculate Number of Clicks

Clicks = (CTR ÷ 100) × Impressions

Example: CTR is 5%, ad shown 10,000 times Clicks = (5 ÷ 100) × 10,000 = 500

3. Calculate Number of Impressions

Impressions = Clicks ÷ (CTR ÷ 100)

Example: Received 500 clicks, CTR is 5% Impressions = 500 ÷ (5 ÷ 100) = 10,000
