Click-through rate (CTR) in social media is a metric that measures the number of clicks on a specific link or content (such as an ad, post, or call-to-action) divided by the total number of impressions or views of that content, expressed as a percentage.
The formula to calculate CTR is:
\[ \text{CTR} = \left( \frac{\text{Number of Clicks}}{\text{Total Impressions}} \right) \times 100 \]
For example, if a post received 500 impressions and was clicked on 50 times, the CTR would be:
\[ \text{CTR} = \left( \frac{50}{500} \right) \times 100 = 10% \]
A higher CTR indicates that the content is engaging and encourages users to interact, making it an important metric for evaluating the effectiveness of social media campaigns and content strategies.
