How to calculate
Calculate the click-through rate of an advertisement or search listing.
Click-through rate = clicks/impressions*100
Worked example
Clicks: 200; Impressions: 10000.
Click-through rate: 2 %.
Assumptions and limits
Use impressions. Reach counts people while impressions count displays; mixing them changes the metric.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
CTR describes clicks relative to impressions. It does not establish whether those clicks were valuable or converted.
