# Usage Analytics

Administrators can leverage recorded [Coveo Analytics data](https://docs.coveo.com/en/259/) to evaluate how users interact with a [search interface](https://docs.coveo.com/en/2741/), identify content gaps, and improve relevancy by generating and examining [dashboards](https://docs.coveo.com/en/256/) and [reports](https://docs.coveo.com/en/266/) within the [Coveo Administration Console](https://docs.coveo.com/en/183/) (see [Coveo Analytics overview](https://docs.coveo.com/en/l3bf0598/)).
[Coveo Machine Learning (Coveo ML)](https://docs.coveo.com/en/1727/) features also require UA data to function.

Since version 2.78.0, Coveo Atomic supports two tracking protocols: the [Coveo UA Protocol](https://docs.coveo.com/en/atomic/latest/usage/atomic-usage-analytics/atomic-coveo-ua/) and the new [Event Protocol (EP)](https://docs.coveo.com/en/atomic/latest/usage/atomic-usage-analytics/atomic-ep/).

Event Protocol is a new standard for sending analytics [events](https://docs.coveo.com/en/260/) to Coveo.

It simplifies event tracking by reducing the number of events sent to Coveo.
For instance, you no longer need to send any `search` events as they're logged server-side when you make a request to the Search API.

The protocol also streamlines the event payload, requiring fewer fields.
Such streamlining results in a more efficient and less error-prone event tracking process, yielding better [machine learning](https://docs.coveo.com/en/188/) [models](https://docs.coveo.com/en/1012/) and [Coveo Analytics reports](https://docs.coveo.com/en/266/).

## Coveo UA vs. EP

> **Important**
>
> [Event Protocol](https://docs.coveo.com/en/o9je0592/) is currently in open beta.
> If you're interested in using Event Protocol, reach out to your Customer Success Manager (CSM).

Since the Atomic V3 release, [Event Protocol](https://docs.coveo.com/en/o9je0592/) is the default tracking protocol.

> **Important**
>
> Only [Coveo for Commerce](https://docs.coveo.com/en/1499/) supports EP at the moment.
> For every other kind of implementation, set `analyticsMode` to `legacy` for the time being.

```javascript
const searchInterface = document.querySelector('atomic-search-interface');

await searchInterface.initialize({
    // ...
    analytics: {analyticsMode: 'legacy'},
});
// ...
```
