Imagine a Malaysian kitchen-appliance parts shop with a verified guide to which rice-cooker inner pots fit the models it stocks. A publisher's appliance-care article links to an old compatibility page that no longer opens. Could the shop suggest its guide instead? Only if it answers the same reader question.
What Is Broken Link Building?
Broken link building means finding a link on another website that points to an unavailable page and suggesting a working, relevant replacement. You check what the source article promised, then offer an accurate alternative if you have one. The editor may update the original link, choose another resource, or do nothing. This is one tactic within link building, not a separate ranking rule.
Do not confuse this with fixing broken links on your own site. If your URL moved, update your internal links and redirect the old URL to a genuinely equivalent page where appropriate. You can then ask publishers linking to your old URL to update their references, but that is reclamation of your own links.
Why Might a Publisher Consider a Replacement?
A good external link helps a reader finish a task. If it leads to a missing page, the source article loses that next step. Google says links help it discover pages and understand relevance, but merely replacing a dead URL does not guarantee a ranking benefit. The useful question is whether your destination fulfils the promise made by the source page.
In the kitchen-appliance example, a link labelled “rice-cooker inner-pot compatibility” should lead to verified model information. A generic shop homepage or a page selling unrelated blenders is not a close replacement, even if it loads quickly.
How Do You Find Relevant Candidates?
Start with pages your customers might actually read: appliance-maintenance guides, parts-resource pages, or articles explaining the same product decision. Open a small number of promising pages and inspect their outgoing references. A link-checking tool can flag possible errors, but its report is a lead, not proof.
For each candidate, record the source page, exact linked URL, anchor text and surrounding sentence. The sentence tells you why that destination was cited. If it points to a manufacturer safety manual, your store's sales page is unlikely to replace it. If it points to a compatibility comparison, a carefully maintained compatibility guide may fit. The backlink quality guide helps assess the source page itself.
How Do You Confirm the Link Is Really Broken?
Open the destination in a browser and inspect its response where possible. A tool's “broken” label may reflect a temporary timeout, blocked crawler or redirect. Check again before contacting someone.
| What you see | What to check next |
|---|---|
| 404 or 410 | The URL is unavailable at that address. Confirm the link is still present on the source page and inspect what it promised. |
| Redirect to another useful page | The original URL may have moved. Read the final page before calling the link broken. |
| 403 | Access may be restricted; it is not evidence that the content was removed. Check the context before making any suggestion. |
| 429, timeout or 5xx | Rate limiting or server trouble may be temporary. Check again rather than pitching a replacement immediately. |
| Page loads but no longer answers the link text | This is an outdated or mismatched reference, not necessarily a dead URL. Describe the issue accurately. |
What Makes Your Page a Real Replacement?
Check the source article's wording, then inspect the old destination's topic if a prior description or version is available. Do not copy someone else's vanished page. Your page should independently answer the same need, with current facts and a clear owner who can maintain it.
For the parts shop, that means a guide to models it really stocks, verified part numbers, exceptions and a way to confirm uncertain fits. If the old link was an official manual, the shop should not present its own guide as equivalent safety instructions. A partial match can be offered as a related resource, but not as a direct replacement. Our high-quality backlinks guide
How Do You Make the Suggestion?
Write to the person responsible for the exact page, if a suitable contact is public. Keep the note short: identify the article and broken URL, explain what readers were expecting, and offer your resource only if it truly addresses that expectation. Let the editor choose whether and how to update the page.
For example: “Your guide to replacing rice-cooker parts links to a compatibility page that currently returns 404. We maintain a model-specific inner-pot guide for the products we stock. If it helps your readers, you can review it here.” Avoid mass mailing, demands for exact anchor text or claims that your page is the only valid replacement.
How Do You Record the Outcome?
Keep the source URL, destination URL, date checked, editor response and live result. Distinguish a repaired link to the original site, a new link to you, an unlinked mention and no change. If a link appears, inspect the live context and any referral visits or enquiries you can measure. Do not infer that one placement caused a ranking change.
Use this tactic selectively. Google's spam policies prohibit links created primarily to manipulate rankings, including automated link creation and low-value content made mainly for link signals. A genuinely useful replacement is more defensible than creating near-duplicate pages for every dead URL. For choosing among tactics, see our link-building strategies guide.
Frequently Asked Questions
What Is Broken Link Building in SEO?
It is finding an unavailable destination linked from another site and suggesting a working page that answers the same reader need. The editor decides whether to change the link.
How Can I Check If a Link Is Broken?
Open the exact destination and check whether it consistently fails. A 404 or 410 may indicate a missing page; redirects, access blocks, rate limits and server errors need separate checks before you call it broken.
How Do I Fix Broken Links in SEO?
On your own site, update links to the correct live page and redirect a moved URL to a genuinely equivalent destination where appropriate. On another site, politely report the issue and suggest a close replacement only if it helps that site's readers.
What Happens If a Link Is Broken?
Readers may lose the promised next step. A destination returning 404 is not indexed as a live page by Google Search, but the source page itself does not automatically disappear because one outgoing link fails.
