What is Click-Through Rate (CTR)?
Click-Through Rate (CTR) is a metric that measures the ratio of users who click on a specific link to the total number of users who view a page, email, or advertisement. It's expressed as a percentage and is commonly used in digital marketing to measure the effectiveness of campaigns.
Formula
The Click-Through Rate is calculated using the following formula:
$$\text{CTR} = \left(\frac{\text{Total Clicks}}{\text{Total Impressions}}\right) \times 100$$
Where:
- Total Clicks = Number of times users clicked on your link/ad
- Total Impressions = Number of times your link/ad was shown
Example Calculation
If your ad received 500 clicks and was shown 25,000 times:
$$\text{CTR} = \left(\frac{500}{25{,}000}\right) \times 100 = 2$$
This means 2% of people who saw your ad clicked on it.
