Signal PPC

CTR Calculator

Calculate your click-through rate (CTR) from clicks and impressions.

The total number of times your ad was shown.

Formula

CTR = (Clicks ÷ Impressions) × 100

CTR measures how often people who see your ad click it. It's a signal of ad relevance and creative appeal — it says nothing on its own about what happens after the click.

Worked Example

If your ad receives 250 clicks from 50,000 impressions, CTR = (250 ÷ 50,000) × 100 = 0.5%.

See CPC and CPM to understand how CTR interacts with cost.
