Broken link building

Long definition

Broken link building rests on a simple trade. Editors don't want broken links on their pages — they hurt UX, signal neglect, and bleed link equity to nowhere. You don't have a backlink. If you can find their broken outbound links and offer a high-quality replacement that matches the original's intent, you save them work and they save you a cold pitch.

The workflow is mechanical:

1. Identify target pages on relevant sites — usually resource pages, "best of" roundups, or long-form guides where outbound links accumulate.
2. Crawl those pages for 404s, 410s, and dead redirects (Ahrefs, Screaming Frog, and httpstatus.io all do this).
3. For each broken link, check what the original resource was (Wayback Machine: web.archive.org).
4. Match against your own content. Either you have an existing equivalent, or you create one specifically to fill the gap.
5. Email the editor with three things: the page, the broken link, your replacement. Brief and useful.

Hit rates are unusually measurable for an outreach tactic. With a tight fit between the original resource and your replacement, conversion rates of 5% to 15% are common. With a loose fit (you're pitching a generic blog post in place of a specific tool), rates fall under 2%.

Two reasons it stays white-hat in 2026:

• The link earned matches editorial intent. The editor wanted a resource on that topic; they got one. No quid pro quo, no incentive distortion.
• It scales linearly with effort, not money. You can't pay your way to faster broken-link discovery. The work is research-bound, which keeps it aligned with the spirit of Google's link scheme guidelines.

The tactic is most efficient in niches with mature content but also high link rot — academic-adjacent topics, longstanding tech tutorials, hobbyist verticals. Less efficient in fast-moving fields where editors keep their pages clean.

Common misconceptions

• "Any broken link on any site will do." Topical fit decides hit rate. A broken link to a competing accountancy guide on an accountancy resource page is a real opportunity. A broken link to a recipe blog on a marketing site, replaced with your marketing post, will be ignored.
• "You need a perfect 1:1 replacement." A close, useful match wins more often than an imperfect exact one. Editors care that the replacement helps their readers; they don't care that it carries the same headline as the original.
• "It's spammy because it's a tactic." Tactics aren't spam by definition. A genuine fix to a real problem is exactly the kind of value exchange Google's guidelines reward.
