# Formats

> Revenue of the last 7 days per ad format, against the weekly average of the 3 previous weeks.

**Formats** groups your ad units by format, so you can see whether a whole type of placement lost revenue, for example after a layout change that affected every top banner.

## How it works

Stealth gives each ad unit a format from words in its name. The first rule that matches wins:

| Format | Words in the ad unit name |
| - | - |
| **Anchor** | HEADERSTICKY, STICKY, ANCHOR |
| **In-text** | INTEXT |
| **In-feed** | INFEED |
| **Vignette** | VIGNETTE, INTERSTITIAL |
| **End of article** | FINAL\_MATERIA |
| **Player** | PLAYER, VIDEO |
| **Top** | TOPO, TOP, BILLBOARD, SUPERBANNER |
| **Side** | LATERAL, HALFPAGE, RETANGULO |
| **Footer** | RODAPE |
| **Flex** | FLEX |
| **Other** | Any name without one of the words above |

A word counts when it stands alone between separators: `HOME_TOP_1` is **Top**, `DESKTOP_1` is not. Spaces and hyphens count as separators.

> [!TIP]
>
> If many ad units fall under **Other**, include one of the words above in their names in Google Ad Manager. The new format appears after the next daily catalog.

## What you see

The page always covers the **last 7 days** against the weekly average of the 3 previous weeks. It has no filters.

| Column | What it shows |
| - | - |
| **Format** | The format name. |
| **Revenue 7d** | Revenue of the format in the last 7 days. |
| **Variation** | Revenue against the weekly average of the 3 previous weeks. |
| **Blocks** | How many ad units have this format. |
| **Clients** | How many clients have ad units in this format. |
| **Biggest drops** | The clients that lost the most in this format, with the estimated drop: the weekly average of the 3 previous weeks minus the last 7 days. |

The format also appears on the [Panel](https://docs.usestealth.dev/en/screens/panel.md) (**Formats Losing Revenue**), on the client page and in the webhook payload, and you can create an [alert exception](https://docs.usestealth.dev/en/alerts/overview.md) for a whole format.
