What is broken link building?
Broken link building is a link building technique: you find links on other websites that point to pages that no longer work, create or pick a page on your site that can replace the missing content, and ask the site owner to update the dead link to point to your page.
It is also called dead link building. The idea is simple. A broken link is a small problem on someone else's page: their readers click it and land on an error. You find the problem, you offer the fix, and the fix happens to be a link to you.
That is why broken link building is usually described as a white hat method. You are not paying for the link or trading favors. The site owner decides whether your page is a good replacement, and the link stays an editorial choice.
It is not a shortcut, though. As an SEO strategy it rewards quality over volume: every step takes judgment about which dead links are worth replacing, what the replacement page must contain, and who on the other website can actually change the link.
Why broken link building works, and when it does not
Most link requests ask the recipient to do you a favor. A broken link request starts with something useful for them: a problem on their page that they probably did not know about. That changes the tone of the whole email, and it gives the editor a reason to reply.
- It helps the other site. Their readers stop hitting a dead page, and the page they wrote keeps working as intended.
- The link already had a place. The editor once decided that a resource on this topic belonged there. You are not asking them to add a new idea, only to restore an old one.
- The prospects come from data. Pages that lost their target still have backlinks, so one dead page can reveal many linking pages at once.
- It fits normal outreach. The same email, follow-up and tracking habits you use elsewhere apply.
It works less well when the dead page was thin, when the linking sites are abandoned, or when many other link builders have already emailed the same editors about the same dead link. Some editors simply remove the broken link instead of replacing it, and that is their call.
Vendor blogs publish reply rates and success rates for broken link outreach, measured on their own users and campaigns. Those numbers are not quoted on this page. Your own tracking sheet, after a few dozen emails, is the only rate that applies to your niche.
Where broken link building fits in link outreach
Broken link building is one of several reasons to contact a site owner about a link. Our guide to backlink outreach covers the whole practice; this page goes deep on one tactic inside it.
| Outreach tactic | The reason you give | How it relates to broken links |
|---|---|---|
| Broken link building | A link on your page is dead, and my page can replace it | This page |
| Link reclamation | You link to a page of ours that moved or died | The same fix, but the dead page is your own |
| Resource page outreach | Your list of resources is missing a useful one | Resource pages are where most dead links hide |
| Unlinked mentions | You mention us without a link | A different reason, often sent to the same editors |
| Guest posts | I can write an article for your readers | A bigger ask, better after a first helpful contact |
In practice these tactics mix. A resource page with a dead link may also be missing a second resource you could suggest. A site that accepted a replacement link may later be open to a guest post. Keep one record per site so every contact builds on the last.
Four kinds of broken link opportunities
Pages on your site that were deleted or moved without a redirect, and still have backlinks. You fix these yourself, first.
A page in your topic that died, often from a closed company or a retired blog, whose backlinks now lead to an error.
A curated list of links where one or two entries no longer work. Fewer prospects per find, but a very clear request.
A competitor's retired guide that still has backlinks. Treat it like any other dead page: offer a better replacement, never a copy.
How to do broken link building, step by step
This is the broken link building process from first search to placed link. It assumes you have a site with content worth linking to, or the time to create it.
Fix your own broken backlinks first
Find pages on your site that return a 404 but still have backlinks, and redirect each one to the closest live page. This is link reclamation, and it needs no outreach.
Find broken links in your topic
Look for dead pages with backlinks in your niche, and for resource pages with dead entries, using a backlink tool, a link checker or a site crawler.
Check that each link is really broken
Open every dead URL yourself. Confirm it returns an error or an empty page today, not a temporary outage or a redirect to a working page.
Vet the linking pages
Keep pages that are relevant to your topic, maintained, and read by real people. Drop abandoned sites, link farms and pages you would not want to be listed on.
Create or choose replacement content
See what the dead page covered, using a web archive, and make sure your page covers the same need better. If you have nothing close, decide whether the prospect list justifies writing it.
Find the person who can change the link
The author of the linking page or the editor of that section, not a general inbox when you can avoid it.
Send a short outreach email
Name the page, the dead link and where it sits, then offer your replacement as one option. Make the fix easy even if they choose another source.
Follow up once, then track the result
One follow-up about a week later, then stop. Record the reply, the link and the date, and check later that the link is still live.
How to find broken links worth replacing
There are four common ways to find broken links. Most link builders use two or three of them together, because each finds a different kind of opportunity.
| Method | What you do | What it finds |
|---|---|---|
| Backlink tool, dead pages report | Filter a competitor or a topic site for pages returning 404 that still have referring domains | Dead pages with many linking pages at once |
| Resource page search | Search for your topic plus words like "resources", "useful links" or "further reading", then check each list | Curated lists with one or two dead entries |
| Browser link checker | Run an extension on a page you are reading to highlight broken outbound links | Dead links on single pages you already found relevant |
| Site crawler | Crawl a whole site in your niche and export external links that return errors | Every broken outbound link on one site |
Start from topics, not from tools. A list of dead pages in an unrelated niche is not a list of prospects, however long it is. The best finds are dead pages on subjects you already cover well.
When a dead page has backlinks from many sites, that is the strongest signal. One replacement page can then be pitched to every site that linked to the original, with one email adapted per site.
Resource pages: the easiest place to start
Resource pages are curated lists of links on a topic: guides for a profession, tools for a hobby, reading lists from a library or a university department. They are maintained by people who care about their links working, and the lists age quickly.
They are a good first project because the request is obvious. The page exists to send readers elsewhere, a dead entry is a visible flaw, and a replacement fits the format the editor already chose.
Check the whole list, not just one link. If two or three entries are dead, mention all of them. The more useful your email is to the editor, the less it reads like a link request.
How to check a link is really broken
Tools report errors that are not always real. Before you email anyone, open the dead URL yourself and look at what comes back.
- A real error: the server answers with a 404 or 410. Google's documentation says it does not index URLs returning a 4xx status code and removes already indexed ones from the index.
- A soft 404: the page loads with a normal status but shows an error message or nothing. Search Console reports these as soft 404 errors. For readers, the link is still broken.
- A redirect: the old URL now redirects to a working page. The link works, so there is nothing to fix.
- A temporary outage: a server error or a timeout today may be gone tomorrow. Check again a day later before you pitch.
Check the date too. A link that broke last week may be fixed by its owner before your email arrives. A link that has been dead for a long time is the one an editor is most likely to thank you for.
How to vet a broken link prospect
A dead link is only an opportunity if the page it sits on is worth a link from. Vet the linking page, not only the domain.
Creating replacement content that earns the link
The replacement page decides the outcome. Editors check whether your page does what the dead page did, and whether their readers will be better off. A page that only matches the title will not pass.
- See what the dead page covered. A web archive usually holds a copy. Note its format, its depth and why people linked to it.
- Read the anchor text on the linking pages. It tells you what the editors expected to find behind the link.
- Cover the same need, better. Update what is outdated, add what is missing, keep the format if the format was the point.
- Never copy the archived page. Rewriting someone else's work is not a replacement, and editors notice.
- Make the page stand alone. No gated download, no pop-up wall before the content an editor needs to see.
Google's own guidance on anchor text describes good anchors as descriptive, reasonably concise and relevant to both pages. If the editor asks how to phrase the new link, suggest the words the old link used, not a keyword you want to rank for.
Sometimes the best replacement is a page you already have. Check before you write anything new, and only build a new page when several prospects are waiting for it.
Dead link outreach: finding the right person
The email has to reach someone who can edit the page. On a blog that is usually the author; on a larger site it may be the editor of that section; on a university or library page it is often the person named at the bottom of the page.
Look for the name on the page itself first: bylines, "maintained by" lines, author bios. Then check the site's contact or about page. A general contact address works, but add the page URL in the subject so it reaches the right person.
Treat this like any other prospecting step: one person, one reason, one record in your sheet. If the page has no owner you can find, it probably has no one who will fix the link either.
A broken link outreach email template
This outreach email template was written for this page. It is short on purpose: the editor should understand the problem, find the dead link and see the fix without scrolling.
Subject: Dead link on your {{pageTopic}} page Hi {{firstName}}, I was reading {{pageTitle}} ({{pageUrl}}) and the link to {{deadResourceName}} in the {{sectionName}} section now leads to an error page. If you want a replacement, we published {{yourPageTitle}}, which covers {{whatItCovers}}: {{yourPageUrl}} Any working source on the topic would fix it, of course. Either way, your readers will not hit the dead page anymore. {{senderName}} {{senderRole}}, {{company}}
The link is not actually broken, or your page does not cover what the dead page covered. One wrong claim tells the editor you ran a tool and did not read their page. Check the link and compare the content before every send.
| Part of the email | Job | Common mistake |
|---|---|---|
| Subject line | Say what is wrong and where | A vague "quick question" or "collaboration" subject |
| First line | Prove you read the page | Flattery that could fit any site |
| The dead link | Make it easy to find: name, section, URL | "A few broken links" with no detail |
| The replacement | Offer your page as one option | Making the fix conditional on linking to you |
| Sign-off | A real name and role | A brand name with no person behind it |
Plain text, no attachments, no tracking-heavy formatting. If you need help with the opening line, see how to introduce yourself in an email, and for the last line, how to end an email.
The follow-up, and when to stop
Editors are busy, and a first email is easy to miss. One follow-up is reasonable; a sequence of five about one dead link is not. This follow-up was also written for this page.
Subject: Re: Dead link on your {{pageTopic}} page Hi {{firstName}}, Just in case this got buried: the {{deadResourceName}} link on {{pageUrl}} still leads to an error page today. Happy to leave it with you. {{yourPageUrl}} is there if it helps. {{senderName}}
The link was fixed or removed since your first email. Check the page again before the follow-up; pointing at a link that is gone looks automated.
After the follow-up, stop. If the editor replaces the link with another source, thank them anyway. The contact is worth more than one link. Our follow-up email templates cover timing in more detail.
Link reclamation: fix your own broken backlinks first
Before you look for dead links on other sites, look at your own. Pages that were deleted, renamed or moved during a redesign often still have backlinks, and those links now land on a 404 error.
Google's Search Console Help says a 404 is not necessarily a problem if a page was removed without any replacement, and that a page that moved should get a 301 redirect to its new location. Its redirect documentation recommends a permanent server-side redirect, with status 301 or 308, when a page has moved for good.
So the fix is usually on your side: redirect each dead URL with backlinks to the closest live page. Outreach is only needed when the new page is a better target than the redirect, or when the linking site sends readers to a URL you cannot redirect, such as a mistyped link.
The Page indexing report in Search Console lists URLs Google found returning 404. A backlink tool shows which of your dead pages still have referring domains. Together they tell you where to start.
What Google's spam policies on links mean for broken link building
Google's spam policies define link spam as creating links to or from a site primarily to manipulate search rankings. The examples include buying or selling links, excessive link exchanges, automated link creation and low-value content made mainly to manipulate linking signals.
A replacement link that an editor chooses because your page helps their readers is not on that list. The same request becomes a problem when you add a payment, a free product, or a promise to link back in exchange.
- Paying for the replacement: exchanging money, goods or services for links is on Google's list of link spam examples.
- "I'll link to you if you link to me": excessive link exchanges are named in the same list.
- Automated mass emails: automated programs or services that create links are named too.
- Paid placements that are marked: Google says paid and sponsored links are fine when qualified with rel="sponsored" or rel="nofollow".
If a site asks for a fee to swap the link, the honest answer is to decline, or to accept that the link must carry a sponsored attribute. Treat a fee request as a sign of how that site handles links in general.
Tools for broken link building
This page does not rank vendors. These are the tool categories a broken link building campaign runs on:
- Backlink index tools: list pages returning errors on any site, with the number of referring domains each still has.
- Site crawlers: crawl one website and export every outbound link that returns an error.
- Browser link checkers: extensions that highlight dead links on the page you are viewing.
- Web archives: show what a dead page contained, so your replacement covers the same need.
- Contact finders: suggest the email address of an author or editor. Verify it before you send.
- Outreach and tracking tools: send one-to-one emails, schedule the follow-up and keep a record per site. A spreadsheet works for small campaigns.
How to measure broken link building
| Metric | What it tells you | If it is low |
|---|---|---|
| Prospects kept after vetting | Whether your finding method targets the right topics | Search closer to what you already cover |
| Reply rate | Whether emails reach the right person and read as useful | Find named editors, shorten the email |
| Links placed per email sent | Whether the replacement page convinces editors | Improve the replacement content |
| Links still live later | Whether the links last | Pitch maintained pages only |
| Referral visits from new links | Whether real readers click | Favor pages with real audiences |
Keep the numbers per campaign, not as one total. A campaign built around one strong dead page and a campaign built on scattered resource pages behave differently, and mixing them hides what works.
Is broken link building scalable?
Partly. Finding dead pages and checking links can be done in bulk. Vetting, writing the replacement and writing each email cannot, without losing what makes the method work: a specific, true message to a person about their page.
A practical way to scale is by dead page, not by email volume. One strong dead page with many linking sites gives you one replacement and many personal emails that differ only in the details. Combine this with a steady cadence, a few emails per day, rather than bursts.
Broken link building also works best as part of a wider mix. The same editors who accept a replacement may be open to other link outreach later, and the general rules of cold email apply to every first contact.
Common broken link building mistakes
- Pitching a link you did not check today, which turns out to be working.
- Offering a page that does not cover what the dead page covered.
- Copying an archived page and calling it a replacement.
- Sending one template to hundreds of pages with no page-specific detail.
- Emailing a general inbox when the author's name is on the page.
- Making the fix conditional on linking to you, or offering payment.
- Following up three or more times about one dead link.
- Skipping your own dead pages, where link reclamation needs no outreach at all.
The email for a site linking to your old page
When a redirect is not enough, for example when a site links to a mistyped URL or to a page you split into two, write to the site owner. The template below was written for this page and asks them to update a link to your own content.
Subject: Updated link for {{oldPageTopic}} on {{theirPageTitle}} Hi {{firstName}}, Thanks for linking to our {{oldPageTopic}} page from {{theirPageUrl}}. We moved that content, and the link now {{whatHappens}}. The current version is here: {{newPageUrl}} If you can update the link, your readers will land on the right page. No other changes needed. {{senderName}} {{senderRole}}, {{company}}
A redirect would have fixed it. If you control the old URL, redirect it to the new page instead of asking anyone to edit their site, and write only when a redirect is impossible or the link is wrong.
Frequently asked questions
What is broken link building?
Broken link building is a link building technique where you find links on other websites that point to dead pages, offer a page on your site as the replacement, and ask the site owner to update the link. It helps their readers and can earn you an editorial link.
Does broken link building still work?
Yes, when the replacement page is genuinely useful and each email is specific to the page. It works less well on abandoned sites, thin dead pages, and dead links that many other link builders have already pitched to the same editors.
How do you find broken links for link building?
Use a backlink tool to find dead pages in your topic that still have backlinks, search for resource pages and check their links, run a browser link checker on relevant pages, or crawl a site in your niche and export its broken outbound links.
What is dead link outreach?
Dead link outreach is the email step of broken link building. You tell the owner or editor of a page that one of its links is dead, show exactly where, and offer your page as one possible replacement, without making the fix conditional on linking to you.
What should a broken link building email say?
Name the page, the dead link and the section it sits in, confirm it leads to an error today, and offer your replacement page with a line on what it covers. Keep it short, in plain text, and signed by a real person.
Is broken link building white hat?
It is generally considered white hat, because the editor chooses whether to use your page. It stops being clean when you pay for the replacement, offer a link swap, or automate mass requests, which Google's spam policies list as link spam.
Is paying for a broken link replacement against Google's rules?
Google's spam policies list exchanging money, goods or services for links as link spam when the link passes ranking credit. Google says paid links are acceptable when marked with rel="sponsored" or rel="nofollow".
What is link reclamation?
Link reclamation is recovering links that point to pages on your own site that moved or no longer exist. Usually you redirect the old URL to the closest live page, and you only contact the linking site when a redirect cannot fix it.
Should you redirect a 404 page that has backlinks?
If the content moved, yes. Search Console Help says a 404 is not necessarily a problem when a page was removed without replacement, but a page that moved should get a 301 redirect to its new location.
What are resource pages in link building?
Resource pages are curated lists of links on a topic, such as guides for a profession or reading lists. They are a good place to find broken links, because the lists age and the editor already wants working resources on the page.
How do you create replacement content for a broken link?
Check what the dead page covered using a web archive, read the anchor text the linking pages used, and make your page cover the same need better and up to date. Never copy the archived page.
How many follow-ups should you send for a broken link?
One, about a week after the first email, with a note that the link is still dead. Check the page again before sending, and stop after that follow-up whatever the result.
What tools do you need for broken link building?
A backlink index tool to find dead pages with links, a site crawler or browser link checker, a web archive, a way to find and verify contact emails, and a spreadsheet or outreach tool to track each site.
What is the difference between broken link building and backlink outreach?
Backlink outreach is the whole practice of contacting sites to earn links. Broken link building is one tactic inside it, where the reason for your email is a dead link you can help replace.
