The formula to calculate the Click To Reach Ratio (CR) is:
\[ CR = \left(\frac{C}{R}\right) \times 100 \]
Where:
Let's say the total number of clicks (C) is 200, and the total reach (R) is 5000 views. Using the formula:
\[ CR = \left(\frac{200}{5000}\right) \times 100 \]
We get:
\[ CR = 4\% \]
So, the Click To Reach Ratio is 4%.
