How it works

CTR is the share of impressions that led to a click: clicks divided by impressions, times 100. The result is a percent between 0 and 100.

CTR % = clicks × 100 ÷ impressions

clicks = CTR % × impressions ÷ 100

impressions = clicks × 100 ÷ CTR %

Worked example

Your ads get 1,250 clicks from 100,000 impressions.

  1. 1CTR1,250 × 100 ÷ 100,000 = 1.25%

What is a good CTR?

Benchmarks vary by industry and platform, so this page gives no number. Compare your CTR across your own ads, placements and audiences.

Questions

Why does the page reject more clicks than impressions?

This calculator treats clicks above impressions as an input mistake, so check that both numbers cover the same ads and dates.

Why does my CTR show 0.00%?

CTR is rounded to 2 decimals. One click in 100,000 impressions is 0.001%, which shows as 0.00%.

How many impressions do I need for a number of clicks?

Choose "Impressions from clicks and CTR". 50 clicks at a 3% CTR need exactly 1,666.67 impressions, which shows as ≈ 1,667.

Is CTR the same as conversion rate?

No. CTR counts clicks per impression. Conversion rate counts conversions per click.
