What the result means
CTR shows the share of recorded impressions that produced a click. It is commonly used for ads, emails, and search results, but comparisons should use the same placement and counting rules.
Before comparing results
- Use the same date range, campaign scope, and counting definitions.
- Check that the numerator is included in the denominator.
- Review total volume and business outcomes beside the rate.
- Document attribution and filtering changes that affect the trend.
