Broken Link Building: How to Turn Dead Links Into Backlinks

Broken link building is a link acquisition strategy that identifies dead links (404 errors) on relevant websites and proposes your content as a replacement. The logic: a site linking to a dead resource has a problem — broken links frustrate users and look bad to search engines. You solve that problem by offering a working replacement. The webmaster benefits (fixed broken link), and you benefit (new backlink).

Broken link building is effective because the proposition is genuinely helpful rather than purely self-serving. You're not asking for a link as a favor — you're helping fix a problem and suggesting a relevant solution. This higher value proposition converts at better rates than cold outreach asking for links without a clear benefit.

Finding Broken Link Opportunities

⠀

Method 1: Find broken links on competitor resource pages

Resource pages in your industry (pages titled "links," "resources," "useful tools," or "further reading") aggregate external links on a topic. Over time, many of these links break as sites go offline or reorganize.

Process:

1. Search "resources" + [your topic] inurl:resources or "useful links" + [your topic] to find resource pages
2. Use Check My Links (Chrome extension) or Screaming Frog to check each page for broken outbound links
3. Identify broken links pointing to content similar to what you have or can create

⠀

Method 2: Find sites linking to dead competitor pages

If a competitor's page has gone offline (deleted content, domain expired, site migration), sites that previously linked to it now have broken links pointing to dead URLs.

Process using Ahrefs:

1. Enter a competitor's domain in Site Explorer
2. Go to Best Pages → by links, filter for 404 pages
3. These are competitor pages that are now dead but had significant backlinks
4. Sites linking to these dead pages are outreach candidates if you have equivalent content

⠀

Method 3: Find broken external links on relevant sites

Use Ahrefs Site Explorer → Outgoing broken links to find broken external links on specific target sites you'd like to get a link from.

⠀

Creating Replacement Content

⠀

Broken link building only works if you have content that genuinely replaces the dead resource:

If you already have relevant content: Verify that your existing content genuinely serves the same purpose as the dead resource. If someone was linking to "a complete guide to local SEO" and you have a comprehensive local SEO guide, that's a natural fit.

If you need to create content: For high-value broken link targets (sites with DR 50+ and multiple linking pages), creating replacement content is worth the investment. Use the Wayback Machine (web.archive.org) to see what the dead page contained — this tells you exactly what to recreate and improve.

Quality requirement: The replacement content should be at least as good as what the dead resource was. Offering a thin replacement for a comprehensive guide won't convert the webmaster — and even if it does, a link from a relevant resource page to weak content has limited value.

⠀

Outreach for Broken Link Building

⠀

⠀

⠀

The outreach email for broken link building follows a specific structure:

Find the right contact: Identify the site owner or webmaster responsible for the page containing the broken link. Tools like Hunter.io, LinkedIn, and the site's contact page help identify the right person.

Pitch structure:

1. Mention the specific page on their site (shows you've actually looked at their content)
2. Point out the specific broken link and where it's broken (helpful, specific)
3. Briefly explain what the dead resource was about
4. Offer your replacement URL as a suggestion
5. Keep it short — under 100 words is ideal

⠀

Example structure:

"Hi [name], I was reading your [page title] and noticed one of your links is no longer working — the link to [dead URL] now returns a 404. That resource covered [brief description]. I've written a similar guide here: [your URL] that might be a useful replacement if you're looking to fix the broken link. Thanks either way."

What to avoid:

• Long, formal pitches with excessive context
• Demanding the link or following up multiple times
• Generic pitches that don't reference the specific broken link

⠀

Conversion rates: Expect 5–15% of outreach to convert to links. Broken link building has higher conversion rates than cold link requests because the pitch provides clear value, but it requires volume — you need many prospects to produce meaningful results.

⠀

Scaling Broken Link Building

⠀

⠀

⠀

Running broken link building at scale requires systematic processes:

Build a prospect database: Maintain a spreadsheet of target sites, pages with broken links, broken link URLs, contact information, and outreach status. Ahrefs and Semrush can export broken link data; processing it consistently is a manual but scalable workflow.

Prioritize by domain authority: Focus outreach on sites with DR 30+ that are relevant to your niche. Low-authority sites aren't worth the effort even if conversion is easier.

Content matchmaking: Keep a library of your best content organized by topic. When a broken link opportunity appears, match it to your closest relevant content quickly rather than starting each outreach from scratch.

Batch outreach: Sending outreach in batches (20–30 emails at once) is more efficient than one-off emails. Keep outreach organized by campaign and track responses systematically.

Follow up once: A single follow-up 7–10 days after initial outreach is appropriate. More follow-ups are counterproductive and damage your sender reputation.

Frequently Asked Questions

⠀

How do I find the content that was on a dead page?

The Wayback Machine (web.archive.org) crawls and archives web pages over time. Enter the dead URL to see snapshots of what was on the page before it went offline. This reveals the content type, depth, and topic — essential information for creating a relevant replacement.

Is broken link building still effective?

Yes — it remains one of the higher-converting link building outreach tactics because the value proposition is clearly helpful. Conversion rates are typically better than cold outreach asking for links to new content. The challenge is scale: finding and processing broken link opportunities requires consistent effort and tools like Ahrefs. For most sites, broken link building is one component of a broader link building strategy rather than the primary tactic.

How many broken links do I need to find to get results?

Expect to identify 50–100 legitimate prospects to convert 5–15 links at typical conversion rates. Volume is necessary because many prospects won't respond, some will say no, and some opportunities won't have good content matches. Start with resource pages and competitor dead pages in your core niche and expand from there.

Can I use this for my own broken links?

Absolutely — this is called broken link reclamation. Check your own site for broken external links using Screaming Frog and fix them. More valuable: if your own content has moved and other sites are still linking to the old URL (returning 404), contact those sites to update the link or ensure your redirects are working correctly so the link equity isn't lost.
