Finding and Fixing Broken Links in Your Bookmarks and Pages
Links decay quietly. A short routine for finding dead links, and a few habits for replacing them, keeps your bookmarks and pages useful.
Why links break
Link rot is the name for the way hyperlinks gradually stop pointing to the page or server they were meant to, because the resource is moved, renamed or taken offline. Common causes include:
- A site is redesigned and its page addresses change without redirects.
- A domain expires and is later used by someone else for something unrelated.
- A service closes, taking its pages and short links with it.
- A document is moved into a members-only area.
The different kinds of broken
The clearest failure is the HTTP 404 error, the standard response meaning the server was reached but could not find the requested page. Others are harder to spot:
- Soft failure. The page loads, but it is a generic home page or a "page not found" message that the server reports as normal.
- Content drift. The address still works, but what is there now is different from what you saved.
- New owner. The domain now belongs to an unrelated party. The page may look fine and still be nothing like the original.
A routine for your bookmarks
- Export your bookmarks from the browser to a file, so you have a backup before cleaning.
- Use a link checker, either a browser extension or a standalone tool, to test every saved address.
- Delete links that return errors and that you no longer need.
- For ones you still want, search for the page's title to find where it moved.
- Open a sample of the "working" links and check they still show what you saved them for.
When the page is gone
Web archives keep snapshots of many public pages. If an article you relied on has disappeared, an archived copy may still be readable. Save the archive address alongside the original, and note the date of the copy.
If you run a website
- When you change a page address, add a permanent redirect from the old address to the new one.
- Check outbound links on a schedule; quarterly is a sensible starting point for a small site.
- Prefer linking to stable pages, such as a document's main page, rather than to search results or session-specific addresses.
- Keep a custom 404 page that helps visitors find their way rather than leaving them stuck.
Small habit, big effect
When you save a bookmark, add a word or two about why you saved it. Six months later that note tells you whether a changed page is still what you wanted.
