* Selectively track/exclude certain users, roles and pages
* Monitor what type of links are tracked (downloads, outgoing and mailto)
* Monitor what files are downloaded from your pages

* Demographics and Interests support (formerly known as DoubleClick remarketing support)
* Anonymize visitors IP address
* DoNotTrack support (non-cached content only)
* Drupal messages tracking
* Modal dialog tracking (Colorbox)
* Access denied (403) and Page not found (404) tracking
* Cache the Google Analytics code on your local server for improved page loading times

* User ID tracking across devices
* Changing URL fragments can be tracked as pageviews
* Debug mode with analytics\_debug.js

Custom integrations can also be provided to send custom events and dimensions via:

### Google Tag Manager

The [Google Tag Manager](https://www.drupal.org/project/google_tag) module allows your site to integrate with [Google Tag Manager (GTM)](https://tagmanager.google.com/) application, which allows you to deploy analytics and measurement tag configurations from a web-based user interface (hosted by Google) instead of requiring administrative access to your website.

To use the module, sign up for GTM and obtain a "container ID" for your website. For development purposes, create a GTM environment for your website.

## 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.varbase.vardot.com/9.0.x/developers/configuring-a-varbase-site/configuring-seo-features.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.
