Finding and Fixing Broken Links in Your Bookmarks and Pages

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:

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:

A routine for your bookmarks

  1. Export your bookmarks from the browser to a file, so you have a backup before cleaning.
  2. Use a link checker, either a browser extension or a standalone tool, to test every saved address.
  3. Delete links that return errors and that you no longer need.
  4. For ones you still want, search for the page's title to find where it moved.
  5. 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

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.
