How to Use the CTR Calculator

CTR, or click-through rate, tells you what percentage of recorded impressions resulted in a click. The same basic formula can be used for advertising, search listings, and other click-based placements when the click and impression definitions match.

1. Calculate CTR

Enter your clicks and impressions. The calculator divides clicks by impressions and multiplies the result by 100.

2. Find clicks from a target CTR

Select Find Clicks, enter impressions and your target CTR, and the calculator estimates the number of clicks represented by that rate.

3. Find impressions from clicks and CTR

Select Find Impressions, enter clicks and CTR, and the calculator works backward to estimate the required impressions.

CTR Formula

CTR = (Clicks ÷ Impressions) × 100

Example: 250 clicks from 10,000 impressions gives a 2.5% CTR.

CTR by 1,000 Impressions

The calculator also shows clicks per 1,000 impressions. This is simply another way to read the same CTR number. For example, a 2.5% CTR equals 25 clicks per 1,000 impressions.

Keep CTR comparisons consistent

• Use clicks and impressions from the same reporting period.
• Keep the click definition consistent, such as link clicks versus another click metric.
• Do not compare different channels as though their CTRs have identical meaning.
• Read CTR alongside conversion rate and business outcomes when evaluating campaign performance.
