# Setting up site analytics
|
||
|
||
As with any other service offered on the web, understanding how your project
|
||
documentation is actually used can be an essential success factor. Material for
|
||
MkDocs natively integrates with [Google Analytics] and offers a customizable
|
||
[cookie consent] and a [feedback widget].
|
||
|
||
[Google Analytics]: https://developers.google.com/analytics
|
||
[cookie consent]: ensuring-data-privacy.md#cookie-consent
|
||
[feedback widget]: #was-this-page-helpful
|
||
|
||
## Configuration
|
||
|
||
### Google Analytics
|
||
|
||
<!-- md:version 7.1.8 -->
|
||
<!-- md:default none -->
|
||
|
||
Material for MkDocs integrates natively with Google Analytics 4[^1]. If you
|
||
already set up Google Analytics and have a property, enable it by adding the
|
||
following lines to `mkdocs.yml`:
|
||
|
||
[^1]:
|
||
Prior to Material for MkDocs 9.2.0, Universal Analytics was supported as
|
||
well. However, since Universal Analytics has been sunset, this integration
|
||
was removed in 9.2.0.
|
||
|
||
``` yaml
|
||
extra:
|
||
analytics:
|
||
provider: google
|
||
property: G-XXXXXXXXXX
|
||
```
|
||
|
||
??? question "How to measure site search usage?"
|
||
|
||
Besides page views and events, [site search] can be tracked to better
|
||
understand how people use your documentation and what they expect to find.
|
||
In order to enable site search tracking, the following steps are required:
|
||
|
||
1. Go to your Google Analytics __admin settings__
|
||
2. Select the property for the respective tracking code
|
||
3. Select the __data streams__ tab and click the corresponding URL
|
||
4. Click the gear icon within the __enhanced measurement__ section
|
||
5. Ensure that __site search__ is enabled
|
||
|
||

|
||
|
||
### Was this page helpful?
|
||
|
||
<!-- md:version 8.4.0 -->
|
||
<!-- md:default none -->
|
||
|
||
A simple [feedback widget] can be included at the bottom of each page,
|
||
encouraging users to give instant feedback whether a page was helpful or not.
|
||
Add the following lines to `mkdocs.yml`:
|
||
|
||
``` yaml
|
||
extra:
|
||
analytics: # (1)!
|
||
feedback:
|
||
title: Was this page helpful?
|
||
ratings:
|
||
- icon: material/emoticon-happy-outline
|
||
name: This page was helpful
|
||
data: 1
|
||
note: >-
|
||
Thanks for your feedback!
|
||
- icon: material/emoticon-sad-outline
|
||
name: This page could be improved
|
||
data: 0
|
||
note: >- # (2)!
|
||
Thanks for your feedback! Help us improve this page by
|
||
using our <a href="..." target="_blank" rel="noopener">feedback form</a>.
|
||
```
|
||
|
||
1. This feature is natively integrated with [Google Analytics][analytics],
|
||
which is why `provider` and `property` are also required. However, it's also
|
||
possible to provide a [custom feedback integration].
|
||
|
||
2. You can add arbitrary HTML tags to the note which is shown after the user
|
||
submitted the feedback, e.g. to link to a feedback form.
|
||
|
||
Both properties, `title` and `ratings`, are required. Note that it's allowed to
|
||
define more than two ratings, e.g. to implement a 1-5 star rating. Since the
|
||
feedback widget sends data to a third-party service, it is, of course, natively
|
||
integrated with the [cookie consent] feature[^2].
|
||
|
||
[^2]:
|
||
If the user doesn't accept the `analytics` cookie, the feedback widget is
|
||
not shown.
|
||
|
||
??? question "How to visualize the collected feedback ratings?"
|
||
|
||
To visualize feedback ratings you'll need to create a custom report with
|
||
[Google Analytics] that will quickly show you the worst- and best-rated
|
||
pages of your project documentation.
|
||
|
||
1. Go to your Google Analytics __dashboard__
|
||
|
||
2. Go to the __configure__ page on the left hand menu, then select
|
||
__custom definitions__
|
||
|
||
3. Click the __custom metrics__ tab and then __create custom metrics__,
|
||
enter the following values:
|
||
|
||
* Metric name: Page helpful
|
||
* Description: Was this page helpful?
|
||
* Event parameter: `data`
|
||
* Unit of measurement: Standard
|
||
|
||
4. Go to the __explore__ page on the left hand menu, create a new
|
||
__blank exploration__
|
||
|
||
5. Configure the report as follows:
|
||
|
||
* Dimensions: Add `Event name` and `Page location`
|
||
* Metrics: Add `Event count` and `Page helpful`
|
||
(the custom metric created in step 3)
|
||
* Rows: `Page location`
|
||
* Values: Drag in both `Event count` and `Page helpful`
|
||
* Filters: Add a new filter for
|
||
`Event name / exactly matches / feedback`
|
||
|
||
!!! warning "Delay in data availability"
|
||
|
||
The report may take 24 hours or longer to begin displaying data
|
||
|
||
Now, after you've saved the report and collected some feedback ratings,
|
||
you'll have a list of all pages with the total number of ratings, and an
|
||
average rating per page. This should help you identify pages that need to
|
||
be improved:
|
||
|
||
!!! danger "Google Analytics 4 does not support average values"
|
||
|
||
To our knowledge, Google Analytics 4 has currently no feature that
|
||
allows to define a custom calculated metric to compute the average
|
||
rating of a page. See #5740.
|
||
|
||
[![feedback report]][feedback report]
|
||
|
||
The following properties are available for each rating:
|
||
|
||
<!-- md:option analytics.feedback.ratings.icon -->
|
||
|
||
: <!-- md:default none --> <!-- md:flag required -->
|
||
This property must point to a valid icon path referencing [any icon bundled
|
||
with the theme][custom icons], or the build will not succeed. Some popular
|
||
combinations:
|
||
|
||
* :material-emoticon-happy-outline: + :material-emoticon-sad-outline: – `material/emoticon-happy-outline` + `material/emoticon-sad-outline`
|
||
* :material-thumb-up-outline: + :material-thumb-down-outline: – `material/thumb-up-outline` + `material/thumb-down-outline`
|
||
* :material-heart: + :material-heart-broken: – `material/heart` + `material/heart-broken`
|
||
|
||
<!-- md:option analytics.feedback.ratings.name -->
|
||
|
||
: <!-- md:default none --> <!-- md:flag required -->
|
||
The value of this property is shown on user interaction (i.e. keyboard focus
|
||
or mouse hover), explaining the meaning of the rating behind the icon.
|
||
|
||
<!-- md:option analytics.feedback.ratings.data -->
|
||
|
||
: <!-- md:default none --> <!-- md:flag required -->
|
||
The value of this property is sent as a data value with the custom event
|
||
that is transmitted to Google Analytics[^3] (or any custom integration).
|
||
|
||
[^3]:
|
||
Note that for Google Analytics, the data value must be an integer.
|
||
|
||
<!-- md:option analytics.feedback.ratings.note -->
|
||
|
||
: <!-- md:default none --> <!-- md:flag required -->
|
||
The value of this property is shown after the user selected the rating.
|
||
It may contain arbitrary HTML tags, which is especially useful to ask the
|
||
user to provide more detailed feedback for the current page through a form.
|
||
It's also possible to pre-fill forms with the URL and title of the current
|
||
page by using the following placeholders:
|
||
|
||
- `{url}` – Page URL
|
||
- `{title}` – Page title
|
||
|
||
```
|
||
https://github.com/.../issues/new/?title=[Feedback]+{title}+-+{url}
|
||
```
|
||
|
||
In this example, when clicking the link, the user is redirected to the "new
|
||
issue" form of your repository, with a pre-filled title including the path
|
||
of the current document, e.g.:
|
||
|
||
```
|
||
[Feedback] Setting up site analytics – /setup/setting-up-site-analytics/
|
||
```
|
||
|
||
An alternative to GitHub issues is [Google Forms].

|
||
|
||
## Usage
|
||
|
||
### Hiding the feedback widget
|
||
|
||
The [feedback widget] can be hidden for a document with the front matter `hide`
|
||
property. Add the following lines at the top of a Markdown file:
|
||
|
||
``` yaml
|
||
---
|
||
hide:
|
||
- feedback
|
||
---
|
||
|
||
# Page title
|
||
...
|
||
```
|
||
|
||
## Customization
|
||
|
||
### Custom site analytics
|
||
|
||
In order to integrate another analytics service provider offering a
|
||
JavaScript-based tracking solution, just follow the guide on [theme extension]
|
||
and create a new partial in the `overrides` folder. The name of the partial is
|
||
used to configure the custom integration via `mkdocs.yml`:
|
||
|
||
=== ":octicons-file-code-16: `overrides/partials/integrations/analytics/custom.html`"
|
||
|
||
``` html
|
||
<script>
|
||
/* Add custom analytics integration here, e.g. */
|
||
var property = "{{ config.extra.analytics.property }}" // (1)!
|
||
|
||
/* Wait for page to load and application to mount */
|
||
document.addEventListener("DOMContentLoaded", function() {
|
||
location$.subscribe(function(url) {
|
||
/* Add custom page event tracking here */ // (2)!
|
||
})
|
||
})
|
||
</script>
|
||
```
|
||
|
||
1. As an example, this variable receives the value set in `mkdocs.yml`,
|
||
which is `"foobar"` for `property`.
|
||
2. If you're using [instant loading], you can use the `location$`
|
||
observable to listen for navigation events, which always emits the
|
||
current `URL`.
|
||
|
||
=== ":octicons-file-code-16: `mkdocs.yml`"
|
||
|
||
``` yaml
|
||
extra:
|
||
analytics:
|
||
provider: custom
|
||
property: foobar # (1)!
|
||
```
|
||
|
||
1. You can add arbitrary key-value combinations to configure your
|
||
custom integration. This is especially useful if you're sharing the
|
||
custom integration across multiple repositories.
|
||
|
||
[theme extension]: ../customization.md#extending-the-theme
|
||
[instant loading]: setting-up-navigation.md#instant-loading
|
||
|
||
### Custom site feedback
|
||
|
||
A custom feedback widget integration just needs to process the events that are
|
||
generated by users interacting with the feedback widget with the help of some
|
||
[additional JavaScript]:
|
||
|
||
=== ":octicons-file-code-16: `docs/javascripts/feedback.js`"
|
||
|
||
``` js
|
||
var feedback = document.forms.feedback
|
||
feedback.addEventListener("submit", function(ev) {
|
||
ev.preventDefault()
|
||
|
||
/* Retrieve page and feedback value */
|
||
var page = document.location.pathname
|
||
var data = ev.submitter.getAttribute("data-md-value")
|
||
|
||
/* Send feedback value */
|
||
console.log(page, data)
|
||
})
|
||
```
|
||
|
||
=== ":octicons-file-code-16: `mkdocs.yml`"
|
||
|
||
``` yaml
|
||
extra_javascript:
|
||
- javascripts/feedback.js
|
||
```
|
||
|
||
|
||
{ #feedback style="margin: 0; height: 0" }
|
||
|
||
