Broken Link Building: link acquisition via broken links
A complete guide to broken link building: how to find broken links on authoritative sites, suggest replacements, and earn quality backlinks using white hat methods.
Broken link building is a white hat SEO strategy where you find broken links (404) on other websites, create relevant content, and ask the webmaster to replace the broken link with yours. It's a win‑win: the site owner gets rid of a broken link, and you earn a quality backlink.
What is Broken Link Building
Broken Link Building (BLB) is a white hat link building method that does not require buying links or spamming. You find pages on other sites that link to non-existent resources (404, 410), locate relevant content on your site (or create it), then contact the webmaster and propose replacing the broken link with yours.
Benefits of BLB:
- Fully white hat — follows Google's guidelines.
- You help webmasters improve their site (remove 404s).
- You earn a link from an authoritative resource, often without competition.
- No payment required (though a small bonus may be offered occasionally).
Finding broken links
Main tools and methods for finding broken links:
- Ahrefs: Site Explorer → enter a competitor's domain or an authoritative site in your niche → go to Outgoing links report → filter by 404 status (broken).
- Semrush: Backlink Audit → find broken outgoing links on your donors.
- Screaming Frog: crawl a donor site and filter pages with 404 status on outbound links.
- Chrome extensions: Check My Links (quickly checks all links on an open page).
- Google Search Console: the Coverage report may sometimes mention external broken links, but it's rare.
Target sites for prospecting:
- Resource pages ('useful links').
- Wikipedia (look for external links that became 404).
- Blogs and news portals (old articles often have outdated links).
- Competitor sites — their broken outgoing links are your opportunity.
Google search queries:
- "useful links" + "your topic"
- intitle:resources inurl:links
- "recommended" + "your topic"
- "helpful resources" site:eduCreating replacement content
When you find a broken link, use the Wayback Machine (archive.org) to see what content was originally there. If it matches your niche and you already have similar (or better) content — great. If not, you will need to create a new page.
Replacement content should be:
- At least as good as the broken page (and ideally fresher and more comprehensive).
- Relevant in topic and intent (not just a generic article on a related subject).
- Permanent (not planned for deletion next month).
Outreach and email templates
After preparing the content, find the donor site's contact (usually on the 'Contact' page or via WHOIS). Write a short, polite email:
Subject: Broken link on your page [URL of the page]
Hello [Name],
I was reading your article [title] and found it very useful. I noticed that the link to [description of broken resource] leads to a 404 page (it's broken).
You might be interested in my article on the same topic: [URL of your content]. It's up to date and contains fresh information.
If you replace the broken link with mine, your readers will have a better experience.
Thanks,
[Your name, site]Send 20–30 emails — conversion rates are typically 5–15%. Do not be discouraged by rejections or silence. Personalization matters (name, specific page). Avoid mass‑spamming — Google values natural patterns.
