My first broken link building campaign produced four high-quality backlinks in two weeks without spending a single dollar. I was running a small digital marketing blog at the time and had been struggling to earn links through traditional outreach. Guest post pitches were getting ignored. Cold emails were landing in spam. I was starting to believe that link building required either a big budget or a well-known brand name.
Then I found a broken link on a resource page at a marketing education website. The page linked to a guide on content strategy that had been deleted months earlier. The link returned a 404 error. I had a similar guide on my own site. I sent the website editor a polite note pointing out the broken link and suggesting my guide as a replacement. Three days later, my link was live on a domain authority 58 website.
That was the moment I understood what made broken link building different from every other outreach tactic. Instead of asking for something, you are offering something. You are helping a website owner fix a real problem on their site while giving them a relevant replacement. The value exchange is genuine on both sides. That is why acceptance rates for broken link outreach consistently outperform cold guest post pitches.

What Is Broken Link Building and Why Does It Work?
Broken link building is a link acquisition tactic where you find dead links on other websites, create or identify content that can replace the missing resource, and reach out to the website owner with a helpful suggestion to swap the broken link for a link to your working content.
A broken link is any hyperlink that returns a 404 error, meaning the destination page no longer exists. Broken links happen when websites delete pages, change URL structures, or shut down entirely. They are a maintenance problem that website owners genuinely want to fix because broken links create a poor experience for their readers and represent a signal issue for their own SEO.
The reason broken link building works better than most other outreach methods is the psychology of the ask. A cold guest post pitch asks a website editor to do work: review your pitch, commission your content, publish it, and manage the relationship. A broken link building email asks them to do something they already intended to do: fix a broken link on their site. You are reducing their workload, not adding to it.
From an SEO perspective, the links earned through broken link building tend to be high quality because they replace links that were already considered valuable enough to include on the host page. If a page linked to a resource before that resource disappeared, the page's editor clearly valued that type of content. Your replacement fits a demonstrated need rather than creating a new one.
1Step 1: Find Relevant Resource Pages and Link-Heavy Content in Your Niche
The most productive source of broken link opportunities is resource pages: pages specifically designed to curate links to useful content on a particular topic. These pages tend to link to many external resources, which means they have more opportunities for broken links than a standard article would.
Search Google using operators designed to surface resource pages in your niche. The most effective search strings for this purpose are your keyword combined with phrases like "useful resources," "helpful links," "further reading," or "recommended tools." For example, if you are in the personal finance space, search "personal finance useful resources" or "budgeting tips recommended links."
Also search for pages that link to specific types of content that often gets deleted: guides, studies, tool pages, and statistics roundups. These content types are updated or removed frequently, which means resource pages linking to them accumulate broken links at a higher rate than pages linking to stable evergreen content.
At this stage, focus on relevance over volume. A resource page about a topic directly related to your niche is a far better target than a high-authority page in a loosely connected industry. Topical relevance is what makes the replacement link valuable to both the host page and to your own SEO.
2Step 2: Check Those Pages for Broken Links
Once you have a list of target resource pages, you need to identify which links on those pages are broken. There are several ways to do this depending on your budget and how many pages you are checking.
The Free Method: Check My Links Chrome Extension
Check My Links is a free Chrome browser extension that scans any web page and highlights all broken links in red. Install it from the Chrome Web Store, navigate to a resource page you want to audit, and click the extension icon. Within seconds it highlights every broken link on the page. This is the fastest method for manually checking individual pages and requires no account or subscription.
The Semi-Free Method: Ahrefs Webmaster Tools
Ahrefs offers a free version of their Webmaster Tools suite that allows you to audit your own website for broken outbound links. While this does not let you audit competitor sites directly, it is useful for finding broken link opportunities on websites where you have access. For competitor research, the paid Ahrefs subscription gives you the ability to run broken link reports on any domain and find every broken outbound link they have across their entire site.
The Free Bulk Method: Screaming Frog SEO Spider
Screaming Frog's desktop crawler is free for up to 500 URLs per crawl. Enter a target website's domain and Screaming Frog will crawl the site and return a report of all outbound links including their HTTP status codes. Filter for 404 responses to see every broken outbound link across the crawled pages. This method is more powerful than the Chrome extension because it audits an entire site at once rather than one page at a time.
3Step 3: Identify the Dead Content and What It Was About
When you find a broken link, your next step is to understand what the deleted content was about so you can identify or create a suitable replacement. This step is where most beginners skip ahead too quickly and it costs them placements.
The most reliable way to see what a deleted page contained is the Wayback Machine at web.archive.org. Paste the broken URL into the Wayback Machine search bar and it will show you archived versions of that page from before it was deleted. In most cases you can see the full content of what the page once contained.
This matters for two reasons. First, it tells you whether your existing content is a genuine match for the deleted resource. A broken link that led to a comprehensive statistics page is not a good fit for a replacement link to a short blog post on the same general topic. The replacement needs to serve the same purpose the original served.
Second, it tells you what content you might need to create if you do not have a suitable replacement already. If you find a high-authority resource page with a broken link to a deleted tool or guide and you do not have equivalent content, creating that content specifically for this campaign is a viable strategy. The effort is justified when the target page has strong authority and genuine relevance to your niche.
4Step 4: Match Broken Links to Your Existing Content
Before writing any outreach emails, audit your own content library and map each broken link opportunity to the most relevant piece you already have. This matching step is where you make the case to yourself before making it to the website editor.
The replacement does not need to be identical to the deleted content. It needs to serve the same reader need. A broken link to a deleted keyword research tutorial can be replaced by your guide on keyword research for beginners. A broken link to a deleted statistics roundup on remote work can be replaced by your research article on the same topic, even if the specific statistics differ.
Be honest with yourself during this step. A weak match is worse than no match. Sending an outreach email suggesting a replacement that does not genuinely serve the same purpose as the deleted content will be ignored or declined, and it leaves a negative impression that reduces your chances with that domain in the future.
If you find multiple broken link opportunities on the same domain, prioritise the one where your replacement content is the strongest match. A higher acceptance rate on well-matched opportunities is more valuable than a higher volume of weak pitches.
5Step 5: Write Outreach Emails That Get Responses
The outreach email is where most broken link building campaigns succeed or fail. The fundamental principle is simple: lead with the value you are providing rather than the link you are requesting.
A broken link building email that works has four components. The first is a specific reference to the broken link itself including the exact URL of the page you found it on and the broken URL. This proves you have actually done the work and are not sending a mass template.
The second is a brief, non-condescending explanation of what the broken link means for their readers. Something like: the link currently returns a 404 error, which means visitors clicking it land on an error page. You do not need to lecture them about SEO. A simple factual note is enough.
The third is your suggested replacement, presented as an option rather than a demand. Phrase it as: I have a guide on this topic that might work as a replacement if you are looking for one. The word might is important here. It keeps the tone helpful rather than presumptuous.
The fourth is brevity. A broken link outreach email should be no longer than five or six sentences. Website editors receive dozens of emails daily. A concise email that respects their time converts significantly better than a long pitch that buries the key information.
One mistake I made early on was mentioning SEO benefits to the recipient. Editors do not want to feel like they are being used for link building. Keep the entire framing around helping their readers and maintaining their site quality. The SEO benefit to you is implied and does not need to be stated.
6Step 6: Follow Up Once and Move On
Most successful broken link building placements come from the first email. But a single polite follow-up sent seven to ten days after the initial email can recover opportunities where your first email was missed or buried.
Keep the follow-up even shorter than the original. Reference your previous email briefly, restate the broken link location in one line, and close with an offer to provide any additional information they need. One follow-up is the maximum for this tactic. Two follow-ups starts to feel pushy and the incremental placement rate from a second follow-up does not justify the reputational cost.
Track your outreach in a spreadsheet with columns for the target URL, the broken link URL, the contact email, the date of your first email, the date of your follow-up, and the outcome. This tracking lets you calculate your acceptance rate across campaigns and identify patterns in which types of pages and niches respond best to your outreach. Over time that data shapes a more targeted prospecting approach.
What Acceptance Rates Should You Actually Expect?
Honest expectations prevent early discouragement. Broken link building acceptance rates vary by niche, by the quality of your replacement content, and by the quality of your outreach writing. Across the campaigns I have run and tracked, acceptance rates tend to fall between 5 and 15 percent of total emails sent.
That sounds low until you consider what it means in practice. A campaign where you identify 100 broken link opportunities, send 80 outreach emails, and earn 8 to 12 placements has produced 8 to 12 high-quality, editorially-placed backlinks from relevant websites. Compare that to the typical cold guest post campaign where acceptance rates often fall below 5 percent and require significantly more content production per placement.
The factors that push acceptance rates toward the higher end of that range are: highly specific replacement content that is an obvious match for the deleted resource, outreach sent to the actual editor or content manager rather than a generic contact address, and resource pages in niches where content creators tend to be active and maintain their sites carefully. Educational websites, non-profit resource pages, and independent blogger resource pages tend to respond better than large corporate websites where maintenance requests fall into bureaucratic black holes.
Frequently Asked Questions About Broken Link Building
The prospecting and outreach phase of a focused campaign takes one to three weeks depending on the scale of your target list and the tools you use. Once a link is placed, Google typically crawls and registers the new backlink within two to four weeks. Measurable ranking movement from a cluster of broken link placements usually appears six to twelve weeks after the links go live, consistent with the timeline for most editorially placed backlinks.
Yes. Broken link building works because it is based on a genuine value exchange rather than a manipulation of the algorithm. Website owners will always have broken links they want to fix. Relevant replacement content will always be worth suggesting. Google's link quality assessments favour editorially placed links from relevant sources, which is exactly what broken link building produces when executed correctly.
The Check My Links Chrome extension is the most beginner-friendly free tool for page-by-page broken link checking. Screaming Frog's free tier, which crawls up to 500 URLs, is the best free option for site-level broken link auditing. For finding broken links across entire competitor websites at scale, Ahrefs or Semrush paid plans are the most efficient, though the free tools are sufficient for getting started.
You can absolutely use existing content. The most efficient broken link building campaigns match broken link opportunities to pages that already exist on your site. Creating new content specifically for a campaign is worth considering only when you find multiple high-authority broken link opportunities pointing to similar deleted resources that you do not yet have a strong match for. In that case, creating one comprehensive piece that addresses the gap can unlock multiple placements.
A response rate of 5 to 15 percent is realistic for most broken link building campaigns. This is significantly higher than cold guest post outreach, which typically produces response rates below 5 percent, because broken link outreach provides a clear and immediate benefit to the recipient. Strong replacement content relevance and personalised outreach that references the specific broken link push acceptance rates toward the higher end of that range.
Yes, with some adjustments. For local businesses, focus on local resource pages: city guides, local business association resource pages, neighbourhood blogs, and local news sites that maintain resource sections. A local electrician finding a broken link on a city council home improvement resource page and suggesting their guide on electrical safety has a genuinely relevant pitch. Local broken link building produces locally relevant backlinks that carry geographic authority signals alongside the standard link equity.
Keep the framing on helping them fix a problem rather than on receiving a link. You can mention that you have content that might serve as a replacement, but framing the email as a link request changes the psychology of the interaction in a way that reduces acceptance rates. The best broken link outreach reads as a genuine tip from someone who noticed a problem on their site, with a helpful suggestion attached.
Be honest with yourself about the match quality. If your replacement is significantly weaker than the deleted resource, the pitch will likely be declined or ignored. Either improve your existing content before outreaching or create a more comprehensive version that genuinely serves the same purpose the original did. A declined pitch on a weak match costs you credibility with that domain for future outreach.
Look for the editor, content manager, or webmaster contact information rather than a generic info address. Check the About page, the Contact page, and the author bylines on the site's blog posts. Tools like Hunter.io offer a free tier that finds email addresses associated with any domain. LinkedIn is also useful for finding the specific person responsible for content on a target website. A personalised email to the right person converts significantly better than a generic submission form.
No. Broken link building is one of the safest link building tactics available because it produces genuine editorial links placed at the discretion of the website owner. There is no link scheme involved, no private blog network, and no manipulation of anchor text at scale. Google's link spam guidance targets manipulative link acquisition patterns. Broken link building, when executed with relevant replacement content and honest outreach, is the opposite of manipulative.
The Best Link Building Tactics Help Both Sides. Broken Link Building Is the Clearest Example of That.
My first broken link campaign produced four links. My tenth produced twenty-three. The process gets faster and more effective as you develop an eye for high-quality broken link targets and refine your outreach copy based on what actually gets responses in your niche.
The mechanics are straightforward. Find relevant resource pages. Check for broken links using free tools. Research the deleted content using the Wayback Machine. Match the broken link to your best replacement. Send a concise, helpful outreach email. Follow up once. Track everything.
What makes broken link building genuinely satisfying beyond the rankings it produces is that it is honest. You are helping website owners fix a real problem. You are providing readers with a working resource instead of a dead link. And you are earning a backlink that Google recognises as a genuine editorial endorsement because that is exactly what it is.
