Description
Divide impressions by positive uniqueReach for frequency and subtract uniqueReach × targetFrequency from impressions for impressionGap.
Marketing rates compare a counted outcome with a declared cohort or exposure base. Reentries, exclusions, and distinct funnel stages can change the denominator substantially.
Divide impressions by positive uniqueReach for frequency and subtract uniqueReach × targetFrequency from impressions for impressionGap.
When to use this tool
Use Campaign Frequency Unique Reach Factor when you need a transparent cohort or exposure ratio.
How to use the tool and how it works
- Enter impressions, uniqueReach, targetFrequency. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read frequency, impressionGap. Use the output convention below.
Divide impressions by positive uniqueReach for frequency and subtract uniqueReach × targetFrequency from impressions for impressionGap.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| impressions | Impressions | Required. Safe integer. |
| uniqueReach | Unique Reach | Required. Safe integer; minimum 1. |
| targetFrequency | Target Frequency | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| frequency | Frequency | Required. Finite number. |
| impressionGap | Impression Gap | Required. Finite number. |

}Limitations and assumptions
- Impressions must be at least unique reach; the mean does not describe individual frequency distribution or prove exposure quality.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
