While the following internal templates are called similar to partials, they do *not* observe the partial template lookup order.

## Google Analytics
|
|
|
|
Hugo ships with internal templates for Google Analytics tracking, including both synchronous and asynchronous tracking codes. As well as support for both v3 and v4 of Google Analytics.
|
|
|
|
### Configure Google Analytics
|
|
|
|
Provide your tracking id in your configuration file:
|
|
|
|
**Google Analytics v3 (analytics.js)**
|
|
{{< code-toggle file="config" >}}
|
|
googleAnalytics = "UA-PROPERTY_ID"
|
|
{{</ code-toggle >}}
|
|
|
|
**Google Analytics v4 (gtag.js)**
|
|
{{< code-toggle file="config" >}}
|
|
googleAnalytics = "G-MEASUREMENT_ID"
|
|
{{</ code-toggle >}}
|
|
|
|
### Use the Google Analytics Template
|
|
|
|
You can then include the Google Analytics internal template:
|
|
|
|
```
|
|
{{ template "_internal/google_analytics.html" . }}
|
|
```
|
|
|
|
|
|
```
|
|
{{ template "_internal/google_analytics_async.html" . }}
|
|
```
|
|
|
|
When using Google Analytics v4 use `_internal/google_analytics.html`.
|
|
|
|
A `.Site.GoogleAnalytics` variable is also exposed from the config.
|
|
|
|
## Disqus
|
|
|
|
Hugo also ships with an internal template for [Disqus comments][disqus], a popular commenting system for both static and dynamic websites. In order to effectively use Disqus, you will need to secure a Disqus "shortname" by [signing up for the free service][disqussignup].
|
|
|
|
### Configure Disqus
|
|
|
|
To use Hugo's Disqus template, you first need to set a single configuration value:
|
|
|
|
{{< code-toggle file="config" >}}
|
|
disqusShortname = "your-disqus-shortname"
|
|
{{</ code-toggle >}}
|
|
|
|
You also have the option to set the following in the front matter for a given piece of content:
|
|
|
|
* `disqus_identifier`
|
|
* `disqus_title`
|
|
* `disqus_url`
|
|
|
|
### Use the Disqus Template
|
|
|
|
To add Disqus, include the following line in templates where you want your comments to appear:
|
|
|
|
```
|
|
{{ template "_internal/disqus.html" . }}
|
|
```
|
|
|
|
A `.Site.DisqusShortname` variable is also exposed from the config.
|
|
|
|
### Conditional Loading of Disqus Comments
|
|
|
|
Users have noticed that enabling Disqus comments when running the Hugo web server on `localhost` (i.e. via `hugo server`) causes the creation of unwanted discussions on the associated Disqus account.
|
|
|
|
You can create the following `layouts/partials/disqus.html`:
|
|
|
|
{{< code file="layouts/partials/disqus.html" download="disqus.html" >}}
|
|
<div id="disqus_thread"></div>
|
|
<script type="text/javascript">
|
|
|
|
(function() {
|
|
// Don't ever inject Disqus on localhost--it creates unwanted
|
|
// discussions from 'localhost:1313' on your Disqus account...
|
|
if (window.location.hostname == "localhost")
|
|
return;
|
|
|
|
var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
|
|
var disqus_shortname = '{{ .Site.DisqusShortname }}';
|
|
dsq.src = '//' + disqus_shortname + '.disqus.com/embed.js';
|
|
(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
|
|
})();
|
|
</script>
|
|
<noscript>Please enable JavaScript to view the <a href="https://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript>
|
|
<a href="https://disqus.com/" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a>
|
|
{{< /code >}}
|
|
|
|
The `if` statement skips the initialization of the Disqus comment injection when you are running on `localhost`.
|
|
|
|
You can then render your custom Disqus partial template as follows:
|
|
|
|
```
|
|
{{ partial "disqus.html" . }}
|
|
```
|
|
|
|
## Open Graph
|
|
An internal template for the [Open Graph protocol](https://ogp.me/), metadata that enables a page to become a rich object in a social graph.
|
|
This format is used for Facebook and some other sites.
|
|
|
|
### Configure Open Graph
|
|
|
|
Hugo's Open Graph template is configured using a mix of configuration variables and [front-matter](/content-management/front-matter/) on individual pages.
|
|
|
|
{{< code-toggle file="config" >}}
|
|
[params]
|
|
title = "My cool site"
|
|
images = ["site-feature-image.jpg"]
|
|
description = "Text about my cool site"
|
|
[taxonomies]
|
|
series = "series"
|
|
{{</ code-toggle >}}
|
|
|
|
{{< code-toggle file="content/blog/my-post" >}}
|
|
title = "Post title"
|
|
description = "Text about this post"
|
|
date = "2006-01-02"
|
|
images = ["post-cover.png"]
|
|
audio = []
|
|
videos = []
|
|
series = []
|
|
tags = []
|
|
{{</ code-toggle >}}
|
|
|
|
Hugo uses the page title and description for the title and description metadata.
|
|
The first 6 URLs from the `images` array are used for image metadata.
|
|
If [page bundles](/content-management/page-bundles/) are used and the `images` array is empty or undefined, images with filenames matching `*feature*` or `*cover*,*thumbnail*` are used for image metadata.
|
|
|
|
Various optional metadata can also be set:
|
|
|
|
- Date, published date, and last modified data are used to set the published time metadata if specified.
|
|
- `audio` and `videos` are URL arrays like `images` for the audio and video metadata tags, respectively.
|
|
- The first 6 `tags` on the page are used for the tags metadata.
|
|
- The `series` taxonomy is used to specify related "see also" pages by placing them in the same series.
|
|
|
|
If using YouTube this will produce a og:video tag like `<meta property="og:video" content="url">`. Use the `https://youtu.be/<id>` format with YouTube videos (example: `https://youtu.be/qtIqKaDlqXo`).
|
|
|
|
### Use the Open Graph Template
|
|
|
|
To add Open Graph metadata, include the following line between the `<head>` tags in your templates:
|
|
|
|
```
|
|
{{ template "_internal/opengraph.html" . }}
|
|
```
|
|
|
|
## Twitter Cards
|
|
|
|
An internal template for [Twitter Cards](https://developer.twitter.com/en/docs/tweets/optimize-with-cards/overview/abouts-cards),
|
|
metadata used to attach rich media to Tweets linking to your site.
|
|
|
|
### Configure Twitter Cards
|
|
|
|
Hugo's Twitter Card template is configured using a mix of configuration variables and [front-matter](/content-management/front-matter/) on individual pages.
|
|
|
|
{{< code-toggle file="config" >}}
|
|
[params]
|
|
images = ["site-feature-image.jpg"]
|
|
description = "Text about my cool site"
|
|
{{</ code-toggle >}}
|
|
|
|
{{< code-toggle file="content/blog/my-post" >}}
|
|
title = "Post title"
|
|
description = "Text about this post"
|
|
images = ["post-cover.png"]
|
|
{{</ code-toggle >}}
|
|
|
|
If `images` aren't specified in the page front-matter, then hugo searches for [image page resources](/content-management/image-processing/) with `feature`, `cover`, or `thumbnail` in their name.
|
|
If no image resources with those names are found, the images defined in the [site config](/getting-started/configuration/) are used instead.
|
|
If no images are found at all, then an image-less Twitter `summary` card is used instead of `summary_large_image`.
|
|
|
|
Hugo uses the page title and description for the card's title and description fields. The page summary is used if no description is given.
|
|
|
|
### Use the Twitter Cards Template
|
|
|
|
To add Twitter card metadata, include the following line between the `<head>` tags in your templates:
|
|
|
|
```
|
|
{{ template "_internal/twitter_cards.html" . }}
|
|
```
|
|
|
