CTR Calculator FAQ
What is CTR used for?
CTR helps measure engagement. Higher CTR often suggests your message or creative is relevant to the audience.
What is a good CTR?
Good CTR varies by format and channel. Benchmark against your own history and campaign objective first.
Can clicks be greater than impressions?
In standard ad reporting they usually should not be. If they are, re-check the source data.
Why is zero impressions invalid?
CTR requires impressions as the denominator, so impressions must be greater than zero.
