# Consent Management Platform (CMP) analytics

{% hint style="success" %}

Didomi Consent Management Platform (CMP) analytics provides your organization with a variety of dashboards that can be subsequently filtered to review key data on how your consent notices are performing on your domains/apps. In this article, we will cover the following for CMP analytics:

* [Dashboard updates](#dashboard-updates)
* [Historical data limits](#historical-data-limits)
* [Measured events](#measured-events)
* [Data sampling](#data-sampling)

{% hint style="warning" %}
**Note**: The following refers to aggregated analytics data captured in Didomi structured CMP dashboards. Consent proofs (the individual historical records of an end-user's consent choices are stored by Didomi for 5 years). 
{% endhint %}

### Dashboard updates

Didomi CMP analytics dashboards are updated daily (at approximately 7:00 AM UTC) with a 1-day delay. 

### Historical data limits

The look-back window for data is dependent on the available date aggregation for a particular dashboard. Please refer to the table for the historical data limits for each dashboard:

<table><thead><tr><th width="184">Shortest aggregation</th><th width="181.166748046875">Historical data limit</th><th>Dashboards</th></tr></thead><tbody><tr><td>Hourly</td><td>14 days</td><td><ul><li>Exploration</li></ul></td></tr><tr><td>Daily</td><td>1 year</td><td><ul><li>Domains &#x26; Apps</li><li>Countries</li><li>Tech</li><li>Web Pageviews</li><li>App Sessions</li><li>North America</li><li>AB Tests</li><li>Notice implementation</li></ul></td></tr></tbody></table>

### Measured events

Didomi SDKs automatically collect events when an end-user interacts with your website, mobile app, etc... The following events are collected and aggregated to generate CMP analytics dashboards:

{% hint style="info" %}
Events with an invalid domain or containing localhost are filtered out from the CMP analytics in your dashboard.

### Data sampling

Aside from the end-user consent decisions event (which is collected and stored by Didomi as legal proof of consent and to demonstrate end-user choices), the remaining events collected by the Didomi SDKs on websites and mobile apps are sampled.&#x20;

Sampling refers to the collection of events from random end-users and then extrapolating the analytics data in your organization's CMP dashboards. The Didomi sampling strategy is currently:

* Every end-user is associated with a unique and random user ID
* User IDs are uniformly distributed into N random buckets through hashing
* Users from the top X% buckets are selected as being part of the sample
* All events from users in the sample are collected

{% hint style="warning" %}
**Note**: The sampling rate varies across event types and platforms.
{% endhint %}

This strategy ensures that the sample is representative of the entire end-use base by selecting purely random end-users and logging all events for those end-users (which ensures that we capture the full behavior of those end-users).
