What is Click-Through Rate (CTR)?

Click-Through Rate (CTR) is a critical digital marketing metric that measures the percentage of people who click on an advertisement, link, or email after viewing it. A higher CTR indicates that your ad creative, headline, or call-to-action is engaging and relevant to your audience.

CTR Calculation Formula

The basic formula for calculating Click-Through Rate is:

$$\text{CTR (\%)} = \left( \frac{\text{Total Clicks}}{\text{Total Impressions}} \right) \times 100$$

You can also rearrange the formula to find the missing variables:

• Total Clicks: $\text{Clicks} = \frac{\text{Impressions} \times \text{CTR}}{100}$
• Required Impressions: $\text{Impressions} = \frac{\text{Clicks} \times 100}{\text{CTR}}$

Additional Marketing Metrics

When ad spend is included, you can evaluate complementary cost performance metrics:

• Cost Per Click (CPC): $\text{CPC} = \frac{\text{Total Ad Spend}}{\text{Total Clicks}}$
• Cost Per Mille / 1,000 Impressions (CPM): $\text{CPM} = \left( \frac{\text{Total Ad Spend}}{\text{Total Impressions}} \right) \times 1000$
