    Broken External Links Checker — do your outbound links still work?

    Outbound links rot over time — the pages you linked to get moved or deleted, leaving dead references on your page. This check looks for external links that now 404. Broken outbound links send users to dead ends, undermine the credibility of the sources you cite, and signal that your content hasn't been maintained — a quiet quality issue that grows as pages age.

    In short: Outbound links should still resolve. Dead external links (link rot) send users to dead ends and weaken the credibility of the sources you cite.

    What does the broken external links check look for?

    It checks whether the outbound links on your page still lead to live pages. Specifically:

    • Dead destinations — external links pointing to pages that now return a 404 or error.
    • Link rot — references that have decayed as the linked sites changed or removed content.
    • Scale — whether dead outbound links are occasional or widespread on the page.

    No broken outbound links passes; a few dead links is a warning; many dead outbound links is a fail.

    How is it evaluated, and how is it scored?

    GEObubbly follows your outbound links and checks whether each destination still responds. It's an extended Links & Authority check that runs partially, since verifying links requires fetching each external destination.

    Why broken external links matter for SEO and GEO

    Linking out to credible sources is a good thing — it backs up your claims and shows your content is well-researched. But external links decay over time through link rot: the pages you cited get moved, restructured or deleted, and your once-useful reference becomes a dead 404. Broken outbound links cause real harm. They send users to dead ends, which is frustrating and erodes trust. They weaken the credibility of your references — a citation that leads nowhere is no citation at all, undermining the very authority you were borrowing. And widespread dead links are a signal of stale, unmaintained content, which works against the freshness and quality engines reward. Unlike internal links, you don't control the destinations, so the only remedy is periodic checking: scan your outbound links, then update each dead one to a current source, point it at an archived copy, or remove it. For GEO, live, credible references reinforce that your content is trustworthy and well-sourced — qualities AI engines value when deciding what to cite.

    How this check scores
    Pass: No broken outbound links found.
    Warning: A few outbound links are dead.
    Fail: Many outbound links no longer resolve.

    FAQ

    Link rot is the gradual decay of outbound links as the pages they point to are moved, restructured or deleted over time. A link that worked when you published it can quietly become a dead 404 months or years later, because you don't control the external sites you've linked to. Link rot is a natural consequence of the web changing, and it accumulates across older content. Because nothing alerts you when an external page disappears, the only way to catch link rot is to periodically check your outbound links and update or remove the ones that have died.
