What is the best way to handle a dead external link when an archived copy still exists?

Why not just delete the link

External links are citations. When you support a claim with a source and later remove the link because the source moved, the claim stays in the text while its evidence disappears. Readers and, to a meaningful degree, search engines value pages that show where their information came from. Deleting links also hollows out older articles, which are frequently the pages carrying the most inbound links to your site and therefore the ones you least want to weaken.

Leaving a dead link in place is not the answer either, since it sends readers to an error and signals neglect. The right response is a short decision tree: look for the source at its new location first, then look for an archived copy, then choose between replacing, annotating, or removing. In most cases something better than deletion is available, and the whole process takes a few minutes per link once you have the habit.

First look for the live replacement

Before reaching for an archive, search for the content at its new home. Sites reorganize, rename sections, and move to new domains far more often than they delete material outright. Search for the exact title, check the organization's current site structure, and look at the author's other published work. A live source is always preferable to a snapshot because it may have been corrected or updated since you cited it, and it will keep working for readers going forward.

Confirm the replacement actually matches what you cited. A page with the same title can be substantially rewritten, and figures or recommendations may have changed. Skim the section you relied on. If the claim is no longer supported, treat the finding as a content problem rather than a link problem: update the claim to match the current source, cite something else that supports it, or remove the sentence entirely rather than propping it up with a link that no longer says what you need.

Linking to an archived copy responsibly

Public web archives keep snapshots of a large share of the web. When you link to one, choose the snapshot closest to the date you originally cited so the content matches what you referenced at the time. Make the archived status visible, either in the link text or in a brief note, so readers understand why the page looks dated and why some elements may not work. That transparency is what keeps an archived citation credible.

Archives have limits. Not every page was captured, some are blocked at the site owner's request, and snapshots frequently lack images, scripts, or interactive elements. Archived content can also be removed later. For legal, medical, financial, or safety information, prefer updating the claim to a current source over preserving an old snapshot, because the purpose of those citations is present-day accuracy rather than a historical record of what a page once said.

When removal is the right call

Remove the link when the source was not essential, when the claim has become common knowledge, when the archived copy is broken or incomplete, or when the original domain has been taken over by unrelated or unsafe content. In that last case the archived snapshot is still fine to reference, but the live link has to go immediately. Keep the surrounding text intact and add a plain-text attribution with the author, publication, and year so the source is still credited even without a link.

Make the decision traceable. Log the URL, the choice you made, and the date. Add an archive-aware rule to your link monitor so that links to archive domains are checked for a valid snapshot response rather than assumed permanent, since archive links can fail too. Review archived links roughly once a year; if a live replacement has appeared in the meantime, swap it back in and note the change so the citation is as strong as it can be.
