3.00% is the example result. Click-through rate divides clicks by impressions. It says nothing by itself about the intent or commercial quality of the visitor.
Compare email clicks with delivered emails. Define whether the click count represents unique recipients or every recorded click.
Separating campaign efficiency from business profit
Click-through rate divides clicks by impressions. It says nothing by itself about the intent or commercial quality of the visitor. Campaign ratios depend on the event being counted. A click, a submitted form, a qualified opportunity and a paying customer are separate outcomes. Combine spend and events from the same campaign window before comparing acquisition costs.
Source and result record
For email click rate, retain Email clicks, Delivered emails together with the output. Record the date of the source values and the unit convention used in the form. That record separates a change in the underlying case from a change in how the information was entered. A saved result without its source values cannot show which assumption produced it.
Example with the supplied inputs
Email clicks: 150; Delivered emails: 5000. Result: 3.00%. The values are illustrative.
Compare one changed input
Email clicks changes from 150 to 165. The result becomes 3.30%. All other inputs remain fixed.
Calculation rule
Result = (([Email clicks]) ÷ ([Delivered emails])) × 100
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Email clicks | 150 | Use the source quantity represented by email clicks. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Delivered emails | 5000 | Use the source quantity represented by delivered emails. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 3.00% is the example result. Click-through rate divides clicks by impressions. It says nothing by itself about the intent or commercial quality of the visitor. Use the formula to distinguish a cash amount, count, percentage or ratio.
