CTR Calculator
Click-Through Rate is the share of impressions that turn into a click, one of the first signals of whether an ad's creative and targeting are actually resonating.
CTR
What This Means
Usually the earliest metric available on a new campaign, showing up before conversions or CPA have enough volume to be meaningful.
The Formula
CTR = (Clicks / Impressions) × 100
Why It Matters
CTR is usually the earliest metric available on a new campaign, showing up before conversions or CPA have enough volume to be meaningful. A low CTR relative to platform benchmarks is one of the clearest early signs that creative, targeting, or message match needs work before spending more.
Example
An ad gets 600,000 impressions and 4,800 clicks. CTR is (4,800 divided by 600,000) times 100, which equals 0.8%.
