If you have been doing SEO for any length of time, you already know that broken links are silent killers. They erode user trust, waste crawl budget, and quietly bleed link equity from pages you have spent months building authority on. The challenge is not understanding why broken links are bad – it is finding every single one of them across a large website before they do lasting damage to your rankings.
Ahrefs has long been the gold standard in the SEO toolset market, and its Broken Link Checker is one of the most feature-rich, data-backed link auditing tools available today. But is it worth the price? Does it surface the right data? And how does it compare to free alternatives?
In this in-depth Ahrefs Broken Link Checker review, we examine every facet of the tool – from its data sources and crawl capabilities to its reporting interface and practical workflow integrations. By the end, you will know exactly whether Ahrefs is the right investment for your broken link strategy and how to use it to maximum effect.

What Is the Ahrefs Broken Link Checker?
The Ahrefs Broken Link Checker is a tool within the Ahrefs suite that identifies both internal and external broken links (typically returning HTTP 404 errors or other non-200 status codes) pointing to or from any website. It operates in two primary modes: analyzing a specific URL or domain you own, and analyzing competitor or third-party websites to find broken link building opportunities.
Unlike standalone broken link checkers, Ahrefs integrates its link analysis with one of the largest backlink databases in the industry, currently indexing over 35 trillion known links. This means when you audit your site’s broken links, you are not just getting a list of dead URLs – you are getting full context on which pages are linking to them, what anchor text is used, the Domain Rating (DR) of referring domains, and how much link equity is potentially being lost.
The tool sits within two primary areas of the Ahrefs platform: Site Audit (for crawling your own site) and Site Explorer (for analyzing backlinks to any URL). Together, they give you a complete picture of your broken link landscape, both on-site and off-site.
Why Broken Links Hurt Your SEO Rankings
Before diving into the tool itself, it is worth grounding the conversation in why broken links matter so much to search performance.
1. Wasted Crawl Budget
When Googlebot crawls your site, it allocates a finite crawl budget – the number of pages it will crawl within a given period. If a significant portion of your internal links point to 404 pages, Google wastes crawl resources on dead ends. On large sites with thousands of pages, this can mean valuable content goes undiscovered and unindexed.
2. Lost Link Equity
Every time an external site links to a page on your domain that no longer exists, that link equity (often called ‘link juice’) goes nowhere. It evaporates rather than flowing to living, ranking pages. For sites that have undergone migrations, redesigns, or URL restructuring, this can mean losing substantial backlink value built up over years.
3. Poor User Experience
Search engines increasingly factor in user experience signals, which is why investing in professional UI UX Design and Development Services can significantly reduce bounce rates and improve engagement. If users click through to your site from search results and immediately encounter a 404 error, they bounce instantly. High bounce rates from critical landing pages send negative signals to Google about your site’s reliability and content quality.
4. Diluted Internal Link Architecture
Internal linking is one of the most underutilized on-page SEO levers. When your internal links lead to broken pages, you fragment the logical flow of link authority across your site architecture. Pages that should be well-supported by internal links instead sit in isolation, limiting their ranking potential.
Ahrefs Broken Link Checker: Core Features Reviewed
Site Audit – Internal Broken Link Detection
The Site Audit module is where Ahrefs shines for internal broken link detection. Once you set up a project and run a crawl, Ahrefs systematically spiders your website and flags every internal link pointing to a non-200 status code URL.
The crawl data is organized into an intuitive dashboard that groups issues by type. For broken links, you get a dedicated report showing:
- The broken destination URL (the dead page)
- The source page (where the broken link originates)
- The anchor text of the broken link
- The HTTP status code returned (404, 410, 500, redirect loops, etc.)
- The number of internal links pointing to each broken URL
This level of granularity makes it easy to prioritize fixes. A broken URL receiving 50 internal links is far more urgent than one receiving a single link. Ahrefs makes this prioritization effortless by sorting issues by impact.
One standout feature in Site Audit is the ability to schedule recurring crawls. You can configure weekly or monthly crawls that automatically detect new broken links introduced through content updates, CMS migrations, or plugin changes. This transforms broken link management from a reactive fire drill into a proactive maintenance workflow.
Site Explorer – External Broken Backlink Analysis
Arguably the most powerful aspect of Ahrefs for broken link management is its backlink analysis capability within Site Explorer. Enter any domain or URL and navigate to the Broken Backlinks report to see every external link pointing to a non-existent page on that site.
The data provided for each broken backlink includes:
- The referring domain and specific linking page
- Domain Rating (DR) and URL Rating (UR) of the referring page
- Anchor text and surrounding context
- The broken destination URL on your site
- Date the link was first and last seen
- Link type (dofollow vs. nofollow)
This is invaluable for two scenarios. First, for your own site – you can identify high-DR backlinks pointing to dead pages and immediately prioritize setting up 301 redirects to recover that link equity. Second, for competitor analysis – you can find broken pages on competitor sites that have accumulated backlinks and then pitch the linking sites with your own content as a replacement. This is the classic broken link building strategy, and Ahrefs executes it better than any other tool.
Filtering and Segmentation Capabilities
The filtering system within Ahrefs’ broken link reports is exceptionally well-designed. You can filter broken links by:
- DR range of the referring domain (target only high-authority links)
- Link type (dofollow only for link equity analysis)
- Traffic of the referring page (target links with real audience potential)
- First seen date (identify newly broken links quickly)
- Platform type (WordPress, Shopify, etc.) for outreach targeting
These filters let you cut through the noise and focus on the broken links that have the greatest SEO impact. For large sites with thousands of broken links, this segmentation capability is not a luxury – it is a necessity.
Batch Analysis and URL-Level Reporting
Beyond domain-level analysis, Ahrefs allows you to analyze broken links at the individual URL level. This is useful when you have redirected a specific page and want to confirm all backlinks pointing to the old URL have been accounted for, or when investigating why a specific page is underperforming despite having strong backlinks.
Ahrefs also supports batch URL analysis through its API, which makes it suitable for enterprise-scale broken link auditing across thousands of URLs simultaneously.
Data Quality and Index Freshness
The quality of any backlink or broken link tool ultimately comes down to two things: the size of its index and how fresh that data is. Ahrefs performs exceptionally well on both counts.
Index Size
Ahrefs crawls the web continuously with its own bot (AhrefsBot) and maintains one of the largest active link indexes available to SEO practitioners. With over 35 trillion known links in its database, it surfaces backlinks that smaller tools simply do not have visibility into. This is particularly important for broken backlink auditing – you cannot recover link equity from links you do not know exist.
Crawl Frequency
Ahrefs recrawls known URLs at varying frequencies based on their authority and change rate. High-DR pages are recrawled more frequently, meaning newly broken links on important pages surface in the tool relatively quickly. For the average website, Ahrefs data is typically 15 to 30 days fresh, though high-priority URLs may be updated within days.
Historical Data
One underappreciated feature is Ahrefs’ historical backlink data. You can look back at a site’s backlink profile over time, which is useful for identifying links that went dead after a site migration or content deletion and have not been corrected. This historical view helps diagnose problems that occurred months or even years ago.
Practical Workflow: How to Use Ahrefs to Fix Broken Links Step by Step
Step 1: Run a Site Audit
- Log into Ahrefs and navigate to Site Audit.
- Create a new project for your domain if you have not already.
- Configure crawl settings – enable JavaScript rendering if your site uses dynamic content.
- Run the crawl and wait for it to complete (time varies with site size).
- Navigate to the Issues tab and filter for ‘Broken links’ or ‘4xx page’ errors.
Step 2: Prioritize by Impact
Sort your broken internal links by the number of internal links pointing to each broken URL. Focus first on:
- Pages with the most internal links pointing to them
- Broken pages that appear in the site navigation or footer
- Broken pages that are linked from high-traffic landing pages
Step 3: Export and Triage
Export the broken links report to CSV. Organize the data into three categories:
- Redirect: Pages that have moved to a new URL – set up a 301 redirect
- Recreate: Pages that were deleted but still have value – restore or rebuild them
- Remove: Links to irrelevant or intentionally deleted pages – update or remove the source link
Step 4: Analyze Broken Backlinks
- Go to Site Explorer and enter your domain.
- Navigate to Backlinks > Broken Backlinks.
- Sort by DR (highest first) to prioritize high-value link recovery.
- Export the list and cross-reference with your redirect implementation plan.
- Set up 301 redirects from broken destination URLs to the most relevant live pages.
Step 5: Broken Link Building Outreach
- In Site Explorer, enter a competitor domain.
- Navigate to Broken Backlinks and filter for dofollow links with DR 40+.
- Identify broken pages that had significant content (use Wayback Machine to preview).
- Create or identify equivalent content on your own site.
- Reach out to the linking sites, notifying them of the dead link and suggesting your page as a replacement.
Step 6: Set Up Scheduled Monitoring
Configure Site Audit to run on a weekly or monthly schedule. Set up email alerts for new critical issues so broken links are caught and addressed before they accumulate. This keeps your site in a state of continuous health rather than requiring periodic emergency audits.
Ahrefs Broken Link Checker vs. Competitors
Ahrefs vs. Screaming Frog
Screaming Frog is the go-to tool for on-site technical SEO crawls and is often the first tool developers reach for when identifying broken internal links. It is highly configurable, supports JavaScript rendering, and can be run on-demand for any site.
However, Screaming Frog does not have a backlink database. It can identify broken links within your own site but cannot tell you which external sites are linking to your broken pages, what their DR is, or how much link equity is at stake. For comprehensive broken link management, Screaming Frog and Ahrefs are complementary rather than interchangeable.
Ahrefs vs. SEMrush
SEMrush offers a similar Site Audit and backlink analysis suite. Its broken link reporting is functional and the interface is polished, but its backlink index is smaller than Ahrefs’, meaning it may miss broken backlinks that Ahrefs would surface. For users already in the SEMrush ecosystem, it covers the basics well. For those who need maximum backlink coverage, Ahrefs maintains an edge.
Ahrefs vs. Moz
Moz Pro includes broken link detection within its site crawl reports and a backlink index via Link Explorer. The Moz interface is approachable for beginners, but the depth of data – particularly for international domains and less prominent websites – does not match Ahrefs. Moz‘s index is also smaller, which matters for competitive broken link building campaigns.
Ahrefs vs. Free Broken Link Checkers
Free tools like Broken Link Checker (brokenlink checker.net), Google Search Console, and W3C Link Checker offer basic functionality but with significant limitations:
- No backlink data – you can only see links on pages you crawl
- Limited scale – free tools often cap the number of URLs they will check
- No prioritization by authority or link equity
- No historical data or scheduling features
For hobby sites or small blogs, a free tool may suffice. For any site where SEO performance directly impacts revenue, the Ahrefs platform delivers a materially different level of insight.
Pricing: Is Ahrefs Worth the Cost?
Ahrefs pricing as of 2024 is structured into four tiers:
- Lite: $99 per month – suitable for freelancers and small sites
- Standard: $199 per month – the most popular plan for growing agencies
- Advanced: $399 per month – for larger teams needing more crawl credits and data access
- Enterprise: Custom pricing – for large agencies and in-house teams with advanced needs
The Site Audit and Site Explorer features used for broken link management are available on all paid tiers, though the number of crawl credits, projects, and export rows scales with plan level. For most SEO professionals running audits on 5 to 10 client sites, the Standard plan strikes the best balance of capability and cost.
When evaluating the cost, consider the alternative: a single high-DR backlink pointing to a dead page on your site represents a potentially significant rankings opportunity being squandered. If recovering even a handful of those links results in ranking improvements that drive incremental organic traffic, the tool pays for itself rapidly – especially when validated through consistent Google rank check tracking. Ahrefs is not cheap, but for professionals who take link management seriously, it is a defensible investment.
Limitations and Areas for Improvement
No tool is without limitations, and intellectual honesty demands that we address where Ahrefs falls short.
Crawl Credit System
Site Audit operates on a crawl credit system, where the number of pages you can crawl per month is capped by your plan. For large enterprise sites with millions of URLs, even the Advanced plan may require careful rationing of crawl credits across projects. This can slow down the frequency with which you can monitor large sites for newly broken links.
Data Lag for New Broken Links
While Ahrefs has excellent crawl frequency for high-authority sites, newly created broken links on lower-authority pages may not surface in the backlink database for several weeks. This means the tool is not ideal for real-time broken link detection on fast-moving sites. For that use case, combining Ahrefs with a server-side monitoring solution or Google Search Console alerts is advisable.
Interface Learning Curve
Ahrefs is a powerful tool with a correspondingly complex interface. New users may find the volume of data and the navigation between Site Audit and Site Explorer reports initially overwhelming. There is a learning curve before you can move through broken link workflows with efficiency. Ahrefs has invested in educational content and tutorials, but the onboarding experience for non-technical users could still be more guided.
No Built-in Redirect Management
Ahrefs identifies broken links and backlinks but does not integrate directly with your CMS to implement redirects. You still need to manually implement 301 redirects through your platform (WordPress, Shopify, custom CMS, or .htaccess). For teams managing large redirect maps, a dedicated redirect management tool alongside Ahrefs is often necessary.
Advanced Use Cases for Power Users
Automated Broken Link Monitoring via API
Ahrefs offers a robust API that allows developers and agencies to automate broken link reporting at scale. You can pull broken backlink data programmatically, feed it into custom dashboards, and trigger automated alerts when high-DR broken backlinks are detected. This is particularly valuable for agencies managing dozens of client sites simultaneously.
Competitor Site Migrations and Vulnerability Windows
When a competitor undergoes a domain migration or major site restructuring, they inevitably create a wave of broken links – at least temporarily. By monitoring competitor broken backlinks during these windows, you can rapidly identify newly broken links with high DR and launch outreach campaigns before the competitor completes their redirect implementation. This is a sophisticated competitive tactic that Ahrefs makes executable.
Content Gap Analysis via Broken Pages
Broken pages on competitor sites that have accumulated links represent content gaps – topics that were once served by a page that no longer exists but clearly attracted organic links. By analyzing what the broken competitor pages covered (using the Wayback Machine or cached versions), you can identify content opportunities that have proven link appeal and create superior versions on your own site.
Building Topical Authority Through Link Recovery
For sites in the process of building topical authority, link recovery is often faster ROI than new link acquisition. Identifying your own broken pages with historical backlinks and either restoring those pages or redirecting those links to thematically relevant live pages accelerates topical authority signals without the time and cost of outreach campaigns.
Who Should Use the Ahrefs Broken Link Checker?
The Ahrefs Broken Link Checker is best suited for:
- SEO professionals and agencies managing multiple client websites where link health is a core deliverable
- In-house SEO teams at mid-to-large companies where site migrations, redesigns, or content pruning regularly create broken link risks
- Link builders running broken link building campaigns at scale who need high-quality data on competitor broken backlinks
- Technical SEOs conducting comprehensive site audits who need both crawl data and backlink context in a single platform
- E-commerce sites with large product catalogs where discontinued product pages frequently generate broken links and lost backlink value
It is less suited for very small sites with minimal content and no active link building strategy, where a free tool or Google Search Console may provide sufficient coverage at no cost.
Final Verdict: Ahrefs Broken Link Checker Review
After a thorough evaluation, the Ahrefs Broken Link Checker earns its place as the most comprehensive broken link management solution available to SEO professionals. Its combination of deep backlink index data, intuitive filtering, scheduled crawl monitoring, and integration with the broader Ahrefs ecosystem makes it significantly more powerful than any standalone or free alternative.
The tool is not without limitations – the crawl credit system can constrain large-scale audits, the interface has a learning curve, and newly broken links may not surface immediately. But these are minor trade-offs compared to the depth of insight the platform provides.
For any SEO professional who is serious about protecting and growing their site’s link equity, catching broken links before they compound, and executing broken link building campaigns with precision, Ahrefs is not just a useful tool – it is an essential one.
Rating: 9.2 / 10 – Highly Recommended for SEO Professionals
