Broken Link Building: The Method, the Tools and Realistic Results

Broken link building means finding dead links on other sites and offering your live page as the replacement. It's worth doing when you target pages that Google and AI engines already trust. Link rot keeps supply high: Pew Research Center found 38% of sampled 2013 webpages had vanished by October 2023.

Broken link building is also an offsite tactic. Offsite means the pages about your brand on sites you don't own. When you target pages AI engines cite, each swap puts your page where AI engines already look. AirOps tracks which third-party pages AI engines cite for each topic.

A mention is an AI answer naming your brand. A citation is an AI answer linking to or footnoting a page as its source. A placement is a live link or mention you earn on another site's page.

What is broken link building?

Broken link building in SEO, short for search engine optimization, is an outreach method. You find a dead link on another site and pitch your page as its replacement. The editor fixes a broken reference, and you earn a relevant link.

Broken link building SEO value comes from that trade. Each swap also widens your offsite footprint. AirOps' 2026 AI search report found content cited across many domains shows up more often.

You solve a real problem on the editor's page, so the ask feels fair. Google says 404 errors don't harm the host site's rankings. Pitch reader experience instead of ranking fear.

Two related tactics sit close to broken link building. They differ on whose URL broke and what you ask the editor to change. Label every prospect before you write, because each tactic needs a different pitch.

Target choice decides your results, and Domain Authority (DA) is a weak guide. DA is Moz's third-party score of a site's link profile, not a Google metric. Judge a site by whether AI engines cite it, not by its DA score alone.

Mention rate is how often AI answers name your brand. Citation rate is how often AI answers cite your own pages. AirOps citation research explains how the two differ.

How do you do broken link building?

This broken link building method finds dead links on cited pages and pitches your page as the fix. Here is how to do broken link building in six steps. Targeting comes first because it shapes every later step.

1. Pick topics where AI engines already cite pages

Start your broken link building strategy with the AI search prompts you want to win, grouped by topic. Rank the cited domains by citation share for each topic. Prioritize recently cited pages, because citations change constantly.

Check smaller, topic-specific sites in your niche too, not only famous domains.

Crystal Carter, Head of AI Search & SEO Communications at Wix, suggests an audit in her AirOps visibility webinar. Check which of your link partners large language models (LLMs) regularly cite, and focus there. She was discussing backlink audits, and the same filter suits broken link building techniques.

In this clip, Crystal Carter, Head of AI Search & SEO Communications at Wix, explains how to check which partners LLMs cite before you invest.

2. Find dead links on those pages

Crawl each cited page for outbound links that return 404 errors. Screaming Frog crawls up to 500 URLs free, and a link-checker browser extension handles single pages. For Wikipedia, search site:wikipedia.org "keyword" intext:"dead link" with your topic. Pew's Wikipedia sample shows 54% of pages carry at least one dead reference.

3. Check what the dead page said

Paste the dead URL into the Wayback Machine to see what the page covered. Note the dead page's angle and any data the editor relied on. Your replacement needs to cover the same ground, or the editor has no reason to swap.

4. Build or match the replacement

Match an existing page when it already covers the dead page's topic. Build a new page when the gap is worth several placements. One strong replacement, pitched to every linking page, earns more than a page per pitch.

5. Email the editor with a specific fix

Your pitch names the exact dead URL and the exact replacement. Keep the list small and researched, because relevance drives replies.

A relevant pitch lets the editor fix a real problem for their readers. Naming the exact dead URL proves you read the page.

A short list of editors who cite your topic beats a scraped list of strangers. Use a short template and fill in every bracket by hand.

Subject: Dead link in [article title]

Hi [first name],

Your article [article title] links to [dead URL] in the [section name] section.
That page now returns a 404.

I wrote [your page title], which covers [topic the dead page covered].
It covers the same ground as the original: [your URL].

Thanks for keeping the page useful for your readers.

[Your name]
[Your role], [Your company]

6. Follow up once

Send one follow-up, then stop. In BuzzStream's follow-up study, the first follow-up drew 1.74% replies and the next touch drew 0.59%. That data comes from digital PR campaigns, and the drop-off pattern still applies to broken link building techniques.

Here is the full broken link building method at a glance. Time per batch stays qualitative because no published dataset times broken link work.

How do I find and fix broken backlinks to my site?

Find 404 pages on your site that still earn links, then 301 redirect each to its closest live page. A broken backlink is a link from another site to your URL that no longer resolves. You find and fix broken backlinks in four steps.

1. Open the Page indexing report in Google Search Console and filter for "Not found (404)".
2. Spot links to your site that stopped resolving with Majestic's Lost Links report.
3. Redirect each relevant URL with a 301 to its closest live equivalent.
4. Point every redirect at a relevant page, never a blanket homepage redirect.

Jairo Guerrero, founder of Organic Hackers, recommends redirecting useful retired pages in an AirOps tech SEO webinar. The same logic applies to URLs that still earn links. The advice is short because the fix is simple.

Google's site-move guidance says permanent redirects don't cause a loss in PageRank. The same page warns against sending many old URLs to one irrelevant page, such as the homepage. Relevant redirects keep the links you already earned working for you.

Broken link building tools compared

The right broken link building tool depends on the step it covers. Free tools handle discovery, and paid tools earn their cost at outreach scale.

Prices come from each vendor's public pricing page, checked in October 2026. One crawler, the Wayback Machine, and one outreach tool cover the full workflow.

None of these tools tells you which pages AI engines cite. The AirOps platform fills that gap with citation data by topic. Use it to pick targets before you crawl anything.

Realistic broken link building results

Expect a low reply rate and slow compounding, and judge results by AI citation and mention impact. Link counts alone undersell this broken link building method.

Reply rates set expectations. In BuzzStream's customer data, link builders averaged 3.59% replies on initial emails, about 1 in 28. That pool includes broken link outreach alongside other tactics, and a reply is not a placement.

Cost benchmarks come from adjacent tactics. In BuzzStream's digital PR survey of about 70 agency leaders and freelancers, the average cost per link was $597. In Editorial.Link's vendor-run survey of 518 SEOs, the $508.95 average acceptable price for one quality link came from 412 respondents. Neither figure measures dead-link outreach, so treat both as reference points.

Target quality drives broken link building SEO results more than domain strength. A high DA score describes a domain's backlinks. It says nothing about whether AI engines cite the page.

Alex Halliday of AirOps has noted that lower domain authority sites perform well in AI citations.

That widens your target list well past the famous domains. A dead link on a niche blog that AI engines cite deserves the same care as a household-name site. Score each prospect first on whether AI engines cite it for your prompts, then on topical fit.

Results build slowly, so set expectations early. Measure at topic level once you have a meaningful number of live placements. A single placement rarely moves a topic on its own.

Measure each placement with AI metrics alongside link counts. Track mention rate for placements on other sites, and track citation rate for your own pages.

Click data misses much of this work. A 2025 Pew Research Center analysis tracked the browsing of 900 U.S. adults. People shown a Google AI summary clicked a result link in 8% of visits, versus 15% without one. Analytics therefore shows only part of AI-driven demand.

Add a where-did-you-hear-about-us field at signup to capture AI-sourced demand. Treat every metric as correlation, since no single link proves a lift.

Pursue broken link building SEO gains for Google rankings, and choose targets by AI citation data. Both goals fit in one broken link building strategy, as long as each target earns its place.

Which agencies offer broken link building services?

Anew Media Group, Vazoola, SEO Discovery, and Magnero all sell broken link building services. Anew Media Group lists prices on its service page and starts engagements at $1,499/mo.

Broken link building services vary most on transparency. Use these vetting questions before you sign.

• Do AI models cite their links for your prompts?
• Can they show the exact URLs they plan to pitch?
• Do they report live placements separately from replies?
• Do they pay site owners for links that pass ranking credit?
• How do they measure mention lift after placements go live?

The last question matters most. Ask how they connect each placement to AI mentions.

Your first broken link building batch

Start with one topic and one replacement page, then expand once the pitch earns placements.

1. Choose one topic and list the prompts you want AI answers to cover.
2. Pull the third-party pages AI engines cite for those prompts, newest citations first.
3. Crawl those pages and log each dead outbound link with its archived content.
4. Pick the dead link with the most linking pages, and match or build its replacement.
5. Pitch every page that links to it, and log replies and live placements weekly.
