-## Redirects
-
-Before creating a new page, make sure it's located correctly to [avoid future
-redirects](https://developers.google.com/speed/docs/insights/AvoidRedirects).
-Redirects affect the site performance and its structure as a whole. Sometimes
-they are necessary, though, and better than returning 404s.
-
-If you deprecate a webpage, don't just delete it, but make sure to redirect
-it to another page.
-
-To redirect a page to another one, add to the page's frontmatter a variable/value
-pair indicating the link to redirect it to. Redirects work for both internal and
-external pages.
-
-```md
----
-# YAML frontmatter
-redirect_to: 'link-to-redirect-the-page-to'
----
-```
-
-To redirect a given page to an internal page, use the relative path starting at the root of the
-website with `/`. See the examples below.
-
-### Redirect examples
-
-To redirect a certain page to the `about.gitlab.com` home page:
-
-```yaml
-redirect_to: '/'
-```
-
-To redirect a given page to an internal page, let's say, the handbook's homepage:
-
-```yaml
-redirect_to: '/handbook/'
-```
-
-To redirect a given page to a certain blog post:
-
-```yaml
-redirect_to: '/2018/08/22/gitlab-11-2-released/'
-```
-
-To redirect a given page to an external page, **always** start with the HTTP protocol:
-
-```yaml
-redirect_to: 'https://docs.gitlab.com'
-```
