# ImpressionShareRow

A single impression share data row.

```
object ImpressionShareRow
```

## Discussion

Each `ImpressionShareRow` represents one combination of date, search term, and country or region in an impression share report. The date field present depends on the granularity chosen in [`ImpressionShareTimeRange`](/documentation/Apple-Ads-Platform-API/ImpressionShareTimeRange): `day` for `DAILY` granularity, `week` for `WEEKLY_SUN_SAT` granularity.

### Impression share encoding

The `lowImpressionShare` and `highImpressionShare` fields use a tiered encoding:

|Impression share|`lowImpressionShare`     |`highImpressionShare`|
|----------------|-------------------------|---------------------|
|0%              |`0`                      |`0`                  |
|1% – 90%        |`x` (for example, `0.23`)|`x` (same value)     |
|91% – 100%      |`0.91`                   |`1`                  |

When both fields are equal and less than `0.91`, the value is a precise single-digit percentage. When `highImpressionShare` is `1`, the app holds more than 90% impression share for that term.

### Example

```json
{
  "day": "2025-01-10",
  "appName": "AwayFinder",
  "promotedObjectId": "123456789",
  "countryOrRegion": "US",
  "searchTerm": "travel planner",
  "lowImpressionShare": 0.23,
  "highImpressionShare": 0.23,
  "rank": 1,
  "searchPopularity1to5": 4
}
```
