Redirects and Bookmarks
If you retire or move an established website, you may need to use redirects or bookmarks to help your users understand and navigate the changes. Below are the requirements and best practices.
Bookmarks are useful when you need to explain changes to your readers. Bookmarks redirect users from the "old" URL to a bookmark Web page. This page explains that the content has moved, that readers need to update their bookmarks and links, and shows them where the new content can be found.
Bookmarks are temporary, and should be set up for either 6 months or 12 months.
Seamless redirects automatically redirect users from the old URL to the new URL. Seamless redirects are useful for quickly forwarding users from one URL to another. However, because seamless redirects are automatic, your readers may not be aware that the URL has changed or that they need to update their bookmarks or links.
Seamless redirects are usually set up for 6 or 12 months. Permanent seamless redirects can be set up in special situations. See requirements for more information.
Short-Term and Long-Term Redirects and Bookmarks
There are three kinds of redirects and bookmarks: short-term, long term, and permanent.
- Short-term redirects and bookmarks are:
- In place for 6 months
- Used for single pages and low-traffic sites that have changed URLs
- Long-term redirects and bookmarks are:
- In place for 1 year
- Used for office-level, deployment, and other large or high-traffic websites that have changed URLs
- Permanent seamless redirects are:
- In place permanently or indefinitely
- Used to correct common user URL errors or in special-case situations
- Approved by the Web Governance Team. Contact the Web Governance Team Facilitator for information on how to start this process.
EERE does not create permanent bookmarks.
A redirect or bookmark can be set up for either an entire directory or for individual pages. Please consolidate your requests and request as few redirects as possible.
To set up a bookmark or a seamless redirect, contact your ActioNET technical contact. Permanent seamless redirects must be approved by the Web Governance Team.
When coding websites, do not link to redirecting URLs. Link to the official, full-length page address instead.
