Deleting a doc results a 404 error. Follow the below instructions to learn how to create a 301 redirect.
When you delete a doc, you're also deleting a URL. The old URL, when visited, will return a
404 - Page Not Found error, which is not the customer experience we want. Additionally, this damages our SEO.
To keep our docs site healthy, follow these steps.
- You must have a GitHub account to contribute to Sumo Logic documentation.
- We recommend adding 2FA protection when contributing to Sumo Logic repositories.
- Help us keep Sumo Logic open and inclusive by reviewing our Code of Conduct.
Step 1: Create a 301 redirect
As an example, let's say we have two existing docs called Nginx app and Nginx (Legacy) app, and we need to deprecate the legacy version.
- In your GitHub authoring tool (like Atom or VS Code), open our cid-redirects.json file, which contains all 301 redirects.
- Add a redirect from the legacy URL you're removing to the new URL that contains the equivalent content.
Step 2: Update all instances of the old URL
If the doc URL you're removing appears in other docs, you'll need to update those instances to prevent broken links.
In your GitHub authoring tool, run a search for the URL you're removing. In this case, it looks like the legacy URL appears in other docs. Check with a Sumo subject matter expert (SME) to confirm that you can replace all with the new URL.
Never do a Find All > Replace All, as this can break unrelated items like image paths. Replace each URL on a one-by-one basis.
Step 3: Delete the doc
Delete the actual .md doc file from the repository (in this example, it'd be
Step 4: Remove doc from navigation
Remove the doc from the navigation menu (sidebars.ts file).
Step 5: Add deprecation note (optional)
If you're deprecating one solution in favor of another (like in our Nginx and Nginx (Legacy) example), you may also want to add a note in the new doc stating the legacy solution has been deprecated. Check with a SME to be sure.
Step 6: Hide from Google results (optional)
It can take months for an old URL to drop from Google search engine results. If you run into a scenario where you need to hide a page immediately from Google, open a GitHub Issue and provide the details for our site admin.
