How to use this tool
Replace the example values with your own inputs. Results update as you type. Keep your measurement period and definitions consistent, then use the result to inform the next question in your advertising review.
The formula
CTR = clicks ÷ impressions × 100.
Worked example
1,500 clicks from 100,000 impressions gives a CTR of 1.50%.
What the result can tell you
Compare the same click definition: all clicks and outbound link clicks are different metrics. CTR alone does not establish profitability.
Is it free, and where do my inputs go?
