1. Introduction: Why Broken Link Building Still Works
Broken link building is one of the oldest tactics in the SEO playbook, and it has survived for a simple reason: it solves a real problem for the site owner you're pitching, not just for you. Every website accumulates dead links over time, pages get deleted, domains expire, old resources get moved without a redirect. A site owner who finds out that a page they link to now returns a 404 has every incentive to fix it, and if you can offer a relevant replacement, you've just earned a backlink that didn't exist five minutes earlier.
The tactic hasn't changed much conceptually since it was first popularised over a decade ago. What has changed is the tooling. Finding broken links by hand, clicking through resource pages one at a time, doesn't scale past a handful of prospects. The tools below do the heavy lifting: crawling pages for dead links, checking who's still linking to now-defunct content, and in some cases managing the outreach that turns a broken link into a live one.
This guide walks through the strongest tools for each stage of the process, with current pricing, so you can build a stack that matches your budget and the scale you're working at.

2. How Broken Link Building Actually Works
Before comparing tools, it helps to be clear on the actual workflow, because different tools solve different parts of it:
- Find a broken link. This could be a dead resource on a competitor's industry roundup, a 404'd page that still has backlinks pointing to it, or a general resource page in your niche with outdated links.
- Verify it's actually broken. A link that returns a soft 404 (a page that loads but shows "content not found") won't always get flagged by a simple status-code checker, so this step matters more than it sounds.
- Check who's linking to it. If you're targeting a dead page rather than a dead link on a resource page, you need to see which sites still link to that now-broken URL — this is where backlink data tools come in.
- Create or identify a replacement. You need a live page that's genuinely useful as a substitute, not just vaguely related.
- Reach out. Email the site owner, point out the broken link, and suggest your replacement.
Most tools below handle steps 1–3. A smaller number also help with step 5.

3. What to Look For in a Broken Link Building Tool
- Crawl depth and limits. Free tools often cap how many pages or URLs you can check per crawl — fine for small campaigns, limiting for agencies.
- Backlink data quality. To find who's linking to a dead page, you need a tool with a real backlink index, not just a link checker.
- Status code accuracy. The best tools distinguish between hard 404s, soft 404s, redirect chains, and server errors, since each needs a different pitch.
- Export and reporting. CSV or Google Sheets export matters once you're tracking dozens of prospects.
- Outreach integration. Some tools stop at discovery; others carry the workflow through to sending the pitch email.

4. The Best Broken Link Building Tools in 2026 (With Pricing)
-
1. Ahrefs
Ahrefs remains the standard-bearer for broken link building because its backlink index is large and frequently refreshed, which matters enormously here — you're specifically hunting for pages that still have live backlinks despite being dead. Its Broken Backlink Finder, built into Site Explorer, lets you enter any competitor's domain and instantly see which of their pages are 404ing while still holding external links.
Price: Lite from $129/month; Standard $249/month; Advanced $449/month; Enterprise $1,499/month. Strengths: The deepest backlink index in this category, which directly determines how many genuine opportunities you'll surface. Weaknesses: Priced well above what a solo practitioner or small site typically needs just for this one use case. Best for: Agencies and in-house teams running broken link building as a recurring, scaled tactic.
-
2. Semrush
Semrush's Backlink Analytics and Site Audit tools cover similar ground to Ahrefs — you can plug in a competitor domain, filter their backlink profile for broken target pages, and export the list. Its Link Monitoring dashboard also tracks when backlinks you've already earned go dead, which closes the loop on a different but related tactic: link reclamation.
Price: Starter (Pro) around $139.95–$165/month; Pro+ (Guru) around $249/month; Advanced (Business) around $455/month. Strengths: Combines broken link discovery with the rest of an SEO toolkit (keyword research, site audits, rank tracking) in one subscription. Weaknesses: Similar cost profile to Ahrefs — it's a suite purchase, not a cheap single-purpose tool. Best for: Teams that want broken link building folded into a broader SEO platform they're already using.
-
3. Screaming Frog SEO Spider
Screaming Frog is the workhorse for crawling specific pages — resource pages, industry roundups, "best of" lists — to find every broken outbound link on them. Point it at a list of prospect URLs and it will return every dead link, along with the exact status code, in minutes. It doesn't have its own backlink index, so it's better suited to checking link-heavy pages than finding dead pages with existing backlinks.
Price: Free version crawls up to 500 URLs; paid licence is $279/year (roughly £199) with no crawl limit. Strengths: Fast, precise, and genuinely affordable for the amount of crawling power it offers. Weaknesses: No backlink index of its own — you'll need to pair it with Ahrefs or Semrush for the "who's linking to this dead page" step. Best for: Practitioners who want a one-time cost rather than a recurring subscription.
-
4. Check My Links
Check My Links is a free Chrome extension that scans the page you're currently viewing and highlights every broken link directly on the page — dead links show up in red. It's the fastest way to manually verify a single resource page before you pitch it, and it requires zero setup.
Price: Free. Strengths: Instant, visual, and genuinely free with no account required. Weaknesses: Checks one page at a time — not built for scanning dozens of prospects at once. Best for: Quick manual verification before sending an outreach email, or for anyone just starting out with the tactic.
-
5. Dead Link Checker
Dead Link Checker offers single-site checks for free with no sign-up, and registering unlocks Multi Check (scanning several sites in one batch) and Auto Check (scheduled recurring scans). It's a straightforward, no-frills tool aimed squarely at finding dead links rather than analysing backlink profiles.
Price: Free for single-site checks; free registration unlocks Multi Check and Auto Check. Strengths: Genuinely free tier that covers the core use case without a paywall. Weaknesses: No backlink data, so it only tells you a link is dead, not who else might be linking to the same dead target. Best for: Budget-conscious SEOs scanning resource pages at a small to medium scale.
-
6. BrokenLinkCheck.com
This tool crawls an entire site (up to its free limit) and returns every broken link found across all pages, which makes it useful for checking large resource hubs or older blogs that have accumulated years of dead links.
Price: Free tier covers up to 3,000 pages; paid reports add sorting, filtering, and CSV export (pricing available on request from the vendor). Strengths: Covers a meaningful volume of pages for free, which is rare in this category. Weaknesses: The interface and reporting feel dated compared to more modern tools. Best for: One-off audits of large sites without committing to a subscription.
-
7. Dr. Link Check
Dr. Link Check positions itself as a professional-grade link checker with support for scheduled monitoring, team collaboration, and detailed status reporting beyond a simple broken/not-broken flag. It's a solid middle ground between the free single-purpose tools and the full SEO suites.
Price: Limited free plan; paid tiers scale with site size (contact vendor for current rates). Strengths: More detailed status reporting than most free tools, including distinguishing redirect issues from true 404s. Weaknesses: Pricing isn't transparently published, which makes budget planning harder upfront. Best for: Teams that need scheduled, ongoing link monitoring rather than one-off checks.
-
8. Mangools (LinkMiner)
LinkMiner, part of the Mangools suite, is primarily a backlink analysis tool, but it includes broken link data as part of its reporting — letting you see a domain's backlink profile alongside which of their linked pages are no longer live. It's a notably cheaper alternative to Ahrefs or Semrush if backlink depth isn't your top priority.
Price: Free tier available; Basic $30.50/month; Premium $40.50/month; Agency $70.50/month. Strengths: Significantly more affordable than the two major suites while still offering real backlink data. Weaknesses: Smaller backlink index than Ahrefs or Semrush, so some opportunities may not surface. Best for: Freelancers and small agencies who want backlink-aware broken link data without enterprise pricing.
-
9. Sitebulb
Sitebulb is a desktop crawler similar in spirit to Screaming Frog but with a more visual, report-driven interface that's easier to hand off to a client. It flags broken internal and external links as part of a broader technical audit, which makes it useful if broken link building is one part of a larger site review rather than a standalone campaign.
Price: 14-day free trial; no permanent free plan (pricing available directly from the vendor). Strengths: Polished, client-friendly reporting that goes beyond just link status. Weaknesses: Overkill if broken link building is the only thing you need it for. Best for: Consultants bundling broken link discovery into full technical SEO audits.
-
10. BuzzStream
BuzzStream isn't a link checker — it's an outreach CRM, and it earns its place on this list because broken link building doesn't end at discovery. Once you've found your prospects, BuzzStream helps you manage the pitch: storing contact details, tracking email sequences, and logging responses so nothing falls through the cracks across dozens of simultaneous outreach threads.
Price: Starter $24/month; Growth $124/month; Professional $299/month; Custom plans from $999/month. Strengths: Turns a spreadsheet of broken-link prospects into a trackable, repeatable outreach pipeline. Weaknesses: Adds cost on top of whatever discovery tool you're already paying for. Best for: Anyone running broken link building at a volume where outreach tracking in a spreadsheet has started to break down.

6. Building a Broken Link Building Workflow That Actually Scales
A practical stack for most SEO professionals looks like this: use Ahrefs or Semrush to find competitor pages that are dead but still hold backlinks, since that step genuinely requires a strong backlink index. Use Screaming Frog or Check My Links to scan niche resource pages for individual dead links you can offer a replacement for. Once you have a list of prospects, move into BuzzStream or even a well-organised spreadsheet to manage the outreach, since this tactic lives or dies on follow-up, not just discovery.
If budget is tight, Mangools' LinkMiner combined with the free Dead Link Checker and Check My Links can cover 80% of the workflow for a fraction of the cost of the two major suites, you'll just surface fewer opportunities per hour of work.
-
7. Common Mistakes That Waste a Good Broken Link Opportunity
- Pitching a weak replacement. If your page isn't genuinely as good as or better than what was there before, most site owners will ignore the email.
- Ignoring soft 404s. A page that loads with a "not found" message but returns a 200 status code won't always get flagged by basic tools — manually spot-check anything borderline.
- Mass-emailing without personalisation. Broken link outreach has a low enough reply rate already; a templated, generic email makes it worse.
- Forgetting to check context. A dead link at the top of a highly relevant resource page is worth far more than one buried in an unrelated blog post from years ago.
-
8. Final Thoughts
Broken link building hasn't lost its effectiveness, it's simply become more competitive, which makes good tooling more valuable, not less. Free tools like Check My Links and Dead Link Checker are genuinely enough to get started and prove the tactic works for your niche. Once you're scaling past a handful of campaigns a month, the backlink depth of Ahrefs or Semrush, paired with an outreach tool like BuzzStream, is what turns broken link building from an occasional win into a repeatable part of your link acquisition strategy.
Whichever tools you pick, the real differentiator isn't the software, it's how relevant and genuinely useful your replacement content is to the site owner you're pitching.
