Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Clicks | 500 |
| Impressions | 25,000 |
| Click-through rate | 2.000% |
With clicks of 500 and impressions of 25,000, the click-through rate works out to 2.000%.
Example 2
With clicks of 1,000 and impressions of 25,000, the click-through rate works out to 4.000%.

Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
