# Statistics

# 📊 Statistics overview

This section provides a comprehensive guide to the different types of statistics available across our platform, how they are updated, and where to find them.


---

## 🔀 What are the types of statistics

We categorize statistics into two main types:

* **Performance & Delivery Statistics**: these statistics are metrics that indicate delivery, visibility, interactivity, on an aggregated and anonymous model
* **Participations Statistics**: these statistics are declarative data like responses to surveys, forms submissions, etc. that describes the user choices and information that he wants to share with the creative owner

## 🧭 Where statistics are displayed

### Performance & delivery statistics

We expose performance and delivery statistics across multiple areas in the Desk app:

* **Global Dashboards**: High-level overviews for advertisers, publishers, networks.
* **Object Lists**: Campaign lists, creative lists, content lists.
* **Object Detail Pages**: Individual views for a campaign, creative, or audience unit.
* **Nested Stats**: Embedded statistics shown inside other objects (e.g., creative stats within a campaign).
* **Reports**: Metrics are selectable in the reporting tools directly; see the reporting section for more details *(→ reporting-tool.md)*

### Participations statistics

Participation statistics are displayed in fewer areas than for performance and delivery statistics

* **Creative & campaign results screens**: Aggregated visualisation of question results showing the number of participants and the selected choices
* **Reports**: Participation reports extracting the full participation data; see the reporting section for more details *(→ reporting-tool.md)*

## 🔁 Update frequencies

We operate with multiple layers of data freshness, depending on the view and context:

| Layer | Description | Update Interval |
|-------|-------------|-----------------|
| Realtime | From live Redis counters | Realtime        |
| Today | Aggregated “so far” data for the day | Every 30 min    |
| Current version | Aggregated data since last resource update combined with live data | Realtime        |
| Global | Fully processed data (up to yesterday) added with the real time data | Realtime        |
| Reporting | Fully processed data (up to last hour) | Every hour      |
| Participation Reporting | Fully processed participation data | Realtime        |

> **caution:** Minor variations may exist between different views due to aggregation delays or caching mechanisms.

## 📦 Data sources

Depending on the type of statistic and view, data may come from:

* **Redis** (live counters)
* **MongoDB** (for participations)
* **MySQL** (for aggregated statistics)


---

## 📐 Accuracy & scope

* All statistics are **tenant-isolated**: each account only sees the data it owns and, if it's a media group, a reseller, etc, the data its children accounts own.
* Filters are automatically enforced to prevent data leakage between clients.
* Some statistics shown in dashboards are aggregated, while others reflect raw or deduplicated values.
