Available report dimensions
Dimensions control how your report groups the data — they are the categories that define each row of your report. Choosing the right dimension or combination of dimensions depends on the question you are trying to answer.
Date dimensions
| Dimension | Description |
|---|---|
| Date | Groups data day by day. Best for short date ranges where you want to see daily trends. |
| Month | Groups data month by month. Useful for longer-range comparisons and monthly performance summaries. |
| Year | Groups data by calendar year. Primarily useful for annual review reports. |
Demand dimension
| Dimension | Description |
|---|---|
| Product | Groups by individual ad product (Standard Display, Instream Video, Standard Native, etc.). More granular than Media Type. |
Inventory dimensions
| Dimension | Description |
|---|---|
| Domain | Groups by website. The starting point for any cross-site comparison. |
| Subdomain | Groups by subdomain within a domain. |
| Media Type | Groups by Display, Video, or Native. A higher-level alternative to Product. |
| Ad Unit | Groups by individual ad placement identifier. The most granular inventory dimension. |
Targeting dimensions
| Dimension | Description |
|---|---|
| Device | Groups by device type: Desktop, Mobile, Tablet, CTV, Feature phone. Almost always reveals a meaningful eCPM gap between Desktop (typically higher) and Mobile (typically higher volume). |

| Country | Groups by country. Essential for understanding geographic revenue contribution. |
Deal dimensions
| Dimension | Description |
