For people migrating existing published content to Hugo static site generator, there’s a good chance you need a mechanism to handle redirecting old URLs. Luckily, redirects can be handled easily with aliases in Hugo.

Let’s assume you create a new piece of content at content/posts/ with url The content is a revision of your previous post at content/posts/ with url You can create an aliases field in the front matter of your new where you can add previous url paths. The following examples show how to create this filed in YAML front matter.

YAML Front Matter of our content/posts/

title: My New post
aliases: ["/posts/my-old-blog-post/", "/post/another-my-old-post-url/"]

How Hugo Aliases Work

When aliases are specified, Hugo creates a directory to match the alias entry. Inside the directory, Hugo creates an .html file specifying the canonical URL for the page and the new redirect target.

For example, a content file at posts/ with the following in the front matter:

title: My New post
aliases: ["/posts/my-old-blog-post/"]

Assuming a baseURL of, the contents of the auto-generated alias .html found at will contain the following:

<!DOCTYPE html>
    <link rel="canonical" href=""/>
    <meta name="robots" content="noindex">
    <meta http-equiv="content-type" content="text/html; charset=utf-8"/>
    <meta http-equiv="refresh" content="0; url="/>

The http-equiv="refresh" line is what performs the redirect, in 0 seconds in this case. If an end user of your website goes to, they will now be automatically redirected to the newer, correct URL. The addition of <meta name="robots" content="noindex"> lets search engine bots know they they should not crawl and index your new alias page.

Aliases are rendered before any content are rendered and therefore will be overwritten by any content with the same location.
