→How to use CTR Calculator
- Enter impressions, clicks, and conversions from the same creative, placement, and reporting period.
- Calculate click-through rate, then keep the post-click and end-to-end conversion rates visible.
- Use the exposure-to-click-to-conversion path to identify whether the main loss occurs before or after the click.
- Segment results by placement, audience, device, and creative before acting on a blended CTR.
Calculator guide
Understanding CTR Calculator
Click-through rate measures the share of recorded impressions that produced clicks. Adding conversions separates creative engagement from the effectiveness of the landing experience after the click.
Calculation method
How the calculation works
CTR = clicks / impressions x 100. Divide clicks by impressions for CTR. Divide conversions by clicks for post-click conversion rate and by impressions for the end-to-end impression conversion rate.
Response path
CTR explains only the first response step
A click is an engagement event, not the final business outcome. The calculator keeps downstream conversion attached to the same exposure base.
Creative diagnosis
Interpreting a high or low CTR
A high CTR may reflect strong relevance, curiosity, or overly broad promises. A low CTR may reflect weak creative or intentionally narrow qualification.
