Broken Link Building: How to Turn Dead Links into Backlinks
Learn broken link building step by step: find dead links in your niche, create a better replacement page and send outreach emails that site owners welcome.
Every website collects broken links over time. Pages get deleted, companies shut down and URLs change without redirects. Broken link building turns that problem into an opportunity: you find a dead link on someone else's site, offer a working replacement from your site, and the owner fixes their page by linking to you.
It works because you are helping first. The site owner gets a fix for a real problem, and you get a relevant, editorial backlink.
How broken link building works
- Find pages in your niche that link to a dead URL.
- Understand what the dead page used to contain.
- Make sure you have a page that is a good replacement, or create one.
- Contact the site owner, point out the broken link and suggest your page.
Step 1: Find broken links in your niche
There are three practical ways to find opportunities.
Resource pages
Resource and "useful links" pages are the best targets because they link out a lot and are rarely maintained. Search for:
- your topic plus "resources"
- your topic plus "useful links"
- your topic plus "recommended sites"
Then check each page for dead links. Free browser extensions such as Check My Links highlight broken links on any page you open, and our free Link Checker lists every link on a page with its status, so you can spot 404s at a glance.
Dead competitor or industry pages
Look for businesses, tools or blogs in your field that have closed down or removed popular content. If a well-known guide disappeared, many sites may still link to it. Paid backlink tools can show you which pages link to a dead URL; free backlink checkers show a limited sample.
Wikipedia and large directories
Wikipedia marks some dead references with a "dead link" tag. You should not add your own links to Wikipedia for SEO (they are nofollow and editors remove promotional edits), but these tags reveal topics where good sources have disappeared. Those same sources are often linked from other sites too.
Step 2: Research the dead page
Open the dead URL in the Internet Archive's Wayback Machine to see what it used to say. This tells you:
- What topic and depth the replacement needs
- Why people linked to it in the first place
- Whether your existing content already covers it
Do not copy the archived content. Use it to understand the need, then write something original and more current.
Step 3: Create or choose the replacement
Your replacement should be at least as useful as the original. If you already have a strong page on the topic, update it so it covers what the dead page offered. If not, decide whether the opportunity is big enough to justify a new page. A dead resource with links from many sites is worth a dedicated page; a single broken link usually is not.
Step 4: Build your outreach list
For each linking page, record:
| Field | Example |
|---|---|
| Page with the broken link | The resource page URL |
| Broken URL | The dead link they point to |
| Anchor text used | How they described it |
| Your replacement URL | Your matching page |
| Contact | Editor or site owner email |
| Status | Sent, follow-up, linked, declined |
Find contacts on the site's About or Contact page. Avoid guessing emails at scale.
Step 5: Send a helpful outreach email
Keep it short and lead with the fix, not with your request.
Subject: Broken link on your [topic] page
Hi [Name], I was reading your page on [topic] and noticed that the link to [old resource name] no longer works. It now returns an error.
If you are looking for a replacement, I recently published [your page title], which covers [what it covers]: [your URL].
Either way, I thought you would want to know about the broken link. Thanks for maintaining a useful resource, [Your name]
Send one polite follow-up after about a week. If they fix the link with a different source, that is their choice; you still helped.
Step 6: Track results
Check your link list every few weeks. When a link goes live, note it and thank the owner. Over time you will learn which page types and email styles get the best response in your niche.
Do not forget your own broken backlinks
The reverse tactic is even easier. Check which external links point to pages on your own site that no longer exist. You can see some of these in Google Search Console and in free backlink checkers. Redirect each dead URL with a 301 to the most relevant live page. No outreach needed.

FAQ
Is broken link building allowed by Google?
Yes. You are suggesting a useful replacement and the site owner decides whether to link. Nothing is paid or automated, so it fits within Google's guidelines.
What response rate should I expect?
It varies widely by niche and by how well your page matches the dead resource. Personalised emails with a genuinely good replacement perform best. Treat it as a numbers and quality game together.
Do I need paid SEO tools for broken link building?
No. Search operators, a free broken link browser extension and the Wayback Machine are enough to start. Paid tools mainly save time when you work at scale.
