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.

In brief

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).
Key to success: your proposal must be genuinely useful. Do not suggest a page that is only vaguely related — aim for almost exact topical match.

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  • Blogs and news portals (old articles often have outdated links).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.

Creating 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).
Tip: sometimes it's easier to create a new page than to search for an existing one. This ensures a perfect match.

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:

PLAINTEXT
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.

Common questions

From prospecting to getting the link may take 2–4 weeks. The longest phases are finding suitable broken links and creating content.
Usually no — it's a white hat method. However, for very authoritative sites, a small compensation may be offered, but that enters gray area.
Send a polite follow‑up after one week. If still no reply, move on. There are always other broken links.
Partially — using Ahrefs, Semrush, or Screaming Frog. But validation and email writing require manual work.
Not really. First create several quality pages on your topic. BLB works only if you have something valuable to offer in return.
