Overview

By default, when Hugo renders a page, the resulting URL matches the file path within the content directory. For example:

content/posts/post-1.md → https://example.org/posts/post-1/

You can change the structure and appearance of URLs with front matter values and site configuration options.

Front matter

slug

Set the slug in front matter to override the last segment of the path. The slug value does not affect section pages.

{{< code-toggle file="content/posts/post-1.md" copy=false fm=true >}} title = 'My First Post' slug = 'my-first-post' {{< /code-toggle >}}

The resulting URL will be:

https://example.org/posts/my-first-post/

url

Set the url in front matter to override the entire path. Use this with either regular pages or section pages.

With this front matter:

{{< code-toggle file="content/posts/post-1.md" copy=false fm=true >}} title = 'My First Article' url = '/articles/my-first-article' {{< /code-toggle >}}

The resulting URL will be:

https://example.org/articles/my-first-article/

If you include a file extension:

{{< code-toggle file="content/posts/post-1.md" copy=false fm=true >}} title = 'My First Article' url = '/articles/my-first-article.html' {{< /code-toggle >}}

The resulting URL will be:

https://example.org/articles/my-first-article.html

In a monolingual site, a url value with or without a leading slash is relative to the baseURL.

In a multilingual site:

• A url value with a leading slash is relative to the baseURL.
• A url value without a leading slash is relative to the baseURL plus the language prefix.

Site type	Front matter url	Resulting URL
monolingual	/about	https://example.org/about/
monolingual	about	https://example.org/about/
multilingual	/about	https://example.org/about/
multilingual	about	https://example.org/de/about/

If you set both slug and url in front matter, the url value takes precedence.

Site configuration

Permalinks

In your site configuration, set a URL pattern for regular pages within a top-level section. This is recursive, affecting descendant regular pages.

{{% note %}} The permalinks defined in your site configuration do not apply to section pages. To adjust the URL for section pages, set url in front matter. {{% /note %}}

Examples

With this content structure:

content/
├── posts/
│   ├── _index.md
│   ├── post-1.md
│   └── post-2.md
└── _index.md

Create a date-based hierarchy, recursively, for regular pages within the posts section:

{{< code-toggle file="config" copy=false >}} [permalinks] posts = '/posts/:year/:month/:title/' {{< /code-toggle >}}

The structure of the published site will be:

public/
├── posts/
│   ├── 2023/
│   │   └── 03/
│   │       ├── post-1/
│   │       │   └── index.html
│   │       └── post-2/
│   │           └── index.html
│   └── index.html
├── favicon.ico
└── index.html

To create a date-based hierarchy for regular pages in the content root:

{{< code-toggle file="config" copy=false >}} [permalinks] '/' = '/:year/:month/:title/' {{< /code-toggle >}}

{{% note %}} A URL pattern defined for the content root is not recursive. {{% /note %}}

Use the same approach with taxonomies. For example, to omit the taxonomy segment of the URL:

{{< code-toggle file="config" copy=false >}} [permalinks] 'tags' = '/:title/' {{< /code-toggle >}}

Front matter url values take precedence over URL patterns defined in permalinks.

Tokens

Use these tokens when defining the URL pattern. The date field in front matter determines the value of time-related tokens.

:year

the 4-digit year

:month

the 2-digit month

:monthname

the name of the month

:day

the 2-digit day

:weekday

the 1-digit day of the week (Sunday = 0)

:weekdayname

the name of the day of the week

:yearday

the 1- to 3-digit day of the year

:section

the content's section

:sections

the content's sections hierarchy. You can use a selection of the sections using slice syntax: :sections[1:] includes all but the first, :sections[:last] includes all but the last, :sections[last] includes only the last, :sections[1:2] includes section 2 and 3. Note that this slice access will not throw any out-of-bounds errors, so you don't have to be exact.

:title

the content's title

:slug

the content's slug (or title if no slug is provided in the front matter)

:slugorfilename

the content's slug (or filename if no slug is provided in the front matter)

:filename

the content's filename (without extension)

For time-related values, you can also use the layout string components defined in Go's time package. For example:

{{< code-toggle file="config" copy=false >}} permalinks: posts: /:06/:1/:2/:title/ {{< /code-toggle >}}

Appearance

The appearance of a URL is either ugly or pretty.

Type	Path	URL
ugly	content/about.md	https://example.org/about.html
pretty	content/about.md	https://example.org/about/

By default, Hugo produces pretty URLs. To generate ugly URLs, change your site configuration:

{{< code-toggle file="config" copy=false >}} uglyURLs = true {{< /code-toggle >}}

Post-processing

Hugo provides two mutually exclusive configuration options to alter URLs after it renders a page.

Canonical URLs

{{% note %}} This is a legacy configuration option, superseded by template functions and markdown render hooks, and will likely be removed in a future release.

{{% /note %}}

If enabled, Hugo performs a search and replace after it renders the page. It searches for site-relative URLs (those with a leading slash) associated with action, href, src, srcset, and url attributes. It then prepends the baseURL to create absolute URLs.

<a href="/about"> → <a href="https://example.org/about/">
<img src="/a.gif"> → <img src="https://example.org/a.gif">

This is an imperfect, brute force approach that can affect content as well as HTML attributes. As noted above, this is a legacy configuration option that will likely be removed in a future release.

To enable:

{{< code-toggle file="config" copy=false >}} canonifyURLs = true {{< /code-toggle >}}

Relative URLs

{{% note %}} Do not enable this option unless you are creating a serverless site, navigable via the file system. {{% /note %}}

If enabled, Hugo performs a search and replace after it renders the page. It searches for site-relative URLs (those with a leading slash) associated with action, href, src, srcset, and url attributes. It then transforms the URL to be relative to the current page.

For example, when rendering content/posts/post-1:

<a href="/about"> → <a href="../../about">
<img src="/a.gif"> → <img src="../../a.gif">

This is an imperfect, brute force approach that can affect content as well as HTML attributes. As noted above, do not enable this option unless you are creating a serverless site.

To enable:

{{< code-toggle file="config" copy=false >}} relativeURLs = true {{< /code-toggle >}}

Aliases

Create redirects from old URLs to new URLs with aliases:

• An alias with a leading slash is relative to the baseURL
• An alias without a leading slash is relative to the current directory

Examples

Change the file name of an existing page, and create an alias from the previous URL to the new URL:

{{< code-toggle file="content/posts/new-file-name.md" copy=false >}} aliases = ['/posts/previous-file-name'] {{< /code-toggle >}}

Each of these directory-relative aliases is equivalent to the site-relative alias above:

• previous-file-name
• ./previous-file-name
• ../posts/previous-file-name

You can create more than one alias to the current page:

{{< code-toggle file="content/posts/new-file-name.md" copy=false >}} aliases = ['previous-file-name','original-file-name'] {{< /code-toggle >}}

In a multilingual site, use a directory-relative alias, or include the language prefix with a site-relative alias:

{{< code-toggle file="content/posts/new-file-name.de.md" copy=false >}} aliases = ['/de/posts/previous-file-name'] {{< /code-toggle >}}

How Aliases Work

Using the first example above, Hugo generates the following site structure:

public/
├── posts/
│   ├── new-file-name/
│   │   └── index.html
│   ├── previous-file-name/
│   │   └── index.html
│   └── index.html
└── index.html

The alias from the previous URL to the new URL is a client-side redirect:

{{< code file="posts/previous-file-name/index.html" copy=false >}}

<html lang="en-us"> <head> </head> </html> {{< /code >}}

Collectively, the elements in the head section:

• Tell search engines that the new URL is canonical
• Tell search engines not to index the previous URL
• Tell the browser to redirect to the new URL

Hugo renders alias files before rendering pages. A new page with the previous file name will overwrite the alias, as expected.

Customize

Create a new template (layouts/alias.html) to customize the content of the alias files. The template receives the following context:

Permalink

the link to the page being aliased

Page

the Page data for the page being aliased
