Click-through rate is the share of impressions that turned into a click: clicks divided by impressions, times 100.

Also called: CTR calculator.

## Inputs
- Clicks (default 250)
- Impressions (default 10000)

## Results
- Click-through rate
- Impressions per click

## Formula

```
CTR = Clicks ÷ Impressions × 100
```

Where:
- Clicks: clicks on the ad or link
- Impressions: times it was shown (the denominator)

## Worked example
1. CTR = 250 ÷ 10,000 × 100 = 2.5%.
2. Impressions per click = 10,000 ÷ 250 = 40.

**Result:** 250 clicks from 10,000 impressions is a 2.5% click-through rate, one click every 40 impressions.

## What the result means

CTR measures how relevant and appealing the ad or listing is to the people who saw it. Compare it within the same placement and format; search, display and email CTRs are not comparable.

## Assumptions and limits
- Clicks and impressions come from the same report and date range.
- Some platforms count all clicks (including on the profile or “more” link), others only link clicks. Use the same definition when comparing.

## Questions

### Is email click rate the same as CTR?

Email click rate divides by emails delivered, not impressions. The click-to-open rate divides by unique opens.
