Broken Link Building: Finding Opportunities and Writing Outreach That Works

Broken link building means finding links on other sites that point to pages that no longer work, and offering the site owner a live page that serves the same purpose. It helps both sides: the site owner fixes a dead end for their readers, and you earn a link to a page that genuinely replaces the missing one. It only works when the replacement is a real equivalent. A broken link is not permission to insert an unrelated page, and outreach that treats it that way is ignored at best and reported as spam at worst.

Why broken links exist

Pages disappear when sites redesign, companies close, studies move to new hosts, tools are discontinued or authors take down old articles. The pages that linked to them keep their links. Google’s documentation notes that URLs returning 404 are eventually removed from the index (Google’s HTTP status code documentation), but links to them remain in other sites’ content until someone edits them.

Finding opportunities

1. Start from topics you can genuinely cover. List the subjects where you have, or can create, an excellent resource.
2. Find dead resources in those topics. Use a backlink tool to find pages in your field that return 404 or have expired domains but still have links pointing to them. Search for resource pages (“[topic] resources”, “[topic] useful links”) and check their outbound links for errors.
3. Check what the dead page was. Use an archived copy (for example, a web archive capture) to see what the page contained and why sites linked to it.
4. List the linking pages. For each dead resource, export the pages linking to it.

A qualification and outreach workflow

Step 1: qualify the dead resource

Step 2: qualify each linking page

• Is the page itself useful and maintained (not an abandoned link directory)?
• Is the link in editorial context, where a replacement would help readers?
• Is there a contact route?

Step 3: prepare the replacement

The replacement must cover what the original covered. If the dead page was a free tool, the replacement should be a free tool, not a sales page. If it was a dataset, provide the data with sources. Archive copies show what readers expected.

Step 4: write the outreach

Keep it short and useful to the recipient:

Subject: Broken link on your [page title]

Hi [name],

On your page "[page title]" ([URL]), the link to [description of dead resource] now returns an error.

If you are looking for a replacement, our [resource name] covers the same [topic/data/tool]: [URL]. It includes [one specific thing the original offered].

Either way, I thought you would want to know about the broken link.

[Name], [role], [organization]

• Lead with their problem, not your request.
• Name the exact page and link.
• Offer the replacement as an option, not a condition.
• Send one follow-up at most.

Step 5: record outcomes

Track: page contacted, date, response, link added (and to which page), link qualification (followed, nofollow, sponsored). Report actual results; response rates differ between fields and sites, so no benchmark from elsewhere applies.

Outreach practices to avoid

• Offer an unrelated page as a “replacement”.
• Offer payment for the link; paid links that pass ranking credit fall under Google’s link spam policy unless qualified as sponsored.
• Mass-email every page linking to a dead resource without checking relevance.
• Recreate a dead resource by copying its archived content; that may infringe copyright and adds nothing.
• Buy an expired domain to redirect its links to your site. That acquires links for ranking purposes, which Google’s link spam policy covers; the same spam policies separately describe expired domain abuse, where an expired domain is repurposed to host low-value content.

Replacing a dead budgeting worksheet

The illustrative case here is a nonprofit financial education site.

• Finding: a popular budgeting worksheet from a closed organization returns 404, and 140 pages link to it, many on school and library resource pages.
• Archive check: the worksheet was a printable monthly budget template with instructions.
• Replacement: the site already offers a free budgeting worksheet with instructions; it adds a printable version to match the original format.
• Qualification: of the 140 pages, 60 are maintained resource pages relevant to personal finance education; the rest are abandoned or unrelated.
• Outreach: 60 personalized emails pointing out the broken link and offering the worksheet as a replacement.
• Record: responses and links logged; outcomes reported as they come in, without projecting a rate.

Broken link building succeeds when the person you contact is glad you wrote. That depends on your replacement being genuinely what their readers were looking for.
