# What is measured by default

If you install Umbraco Engage we will automatically collect a lot of data for you.

Serverside the following data is tracked:

* The URL of the visited page (`/foobar/`)
* The query string of the visited page (`?filtering=on&parameter1=2`)
* The variant of the page that we serve. This could be a personalized version of the page or one of the A/B-test variants.
* The time that the page was visited (`31 august 2021, 16:04:22`)
* Where the visitor came from before this visit (the so-called referrer). This could be an internal webpage (`/my-contentpage/`) or an external URL (`www.umbraco.com/products/engage/`)
* The browser being used (Firefox), the Operating System used (Windows), and the type of device being used (Desktop). These data points are based on the user-agent string that any browser is sending.
* The IP address (`213.62.44.123`) or anonymized IP address (`213.62.44.0`), depending on your configuration.

With the data collected, the Analytics reports in Umbraco Engage can be visualized. It also allows us to calculate other metrics, such as conversion rates, bounce rates, and landing & exit pages.

By [including the clientside collection script](/umbraco-engage/17.latest/developers/analytics/client-side-events-and-additional-javascript-files.md), you can also capture visitor behavior data.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.umbraco.com/umbraco-engage/17.latest/marketers-and-editors/analytics/what-is-measured-by-default.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
