88% of users won’t return after a bad website experience (Sweor) | 3.8% average crawl budget wasted on broken URLs per site (Ahrefs) | 404 errors are the #1 technical SEO issue found in audits (SEMrush) | 26% of links on the web are broken after 2 years (Ahrefs Study) |
Introduction: The Silent Rankings Killer
Broken links are one of the most common , and most overlooked , technical SEO issues on the web. A broken link is any hyperlink that leads to a page that no longer exists, returning a 404 (Not Found) error or another error response. They accumulate silently over time as pages are deleted, URLs change, and external websites go offline.
The consequences are significant. For users, a broken link signals an unprofessional, poorly maintained website and often ends their visit immediately. For search engines, broken links waste precious crawl budget, fragment your internal link equity, and can prevent important pages from being discovered and indexed. For your off-page SEO, broken backlinks , links from other websites pointing to pages that no longer exist on your site , represent lost authority that is simply draining away.
But there is also an opportunity here. Broken link building , the practice of finding broken links on other websites and offering your content as a replacement , is one of the most effective and Google-compliant link building techniques available. When done correctly, it wins high-quality backlinks naturally and at scale.
This complete guide covers everything you need to know: what types of broken links exist, exactly how they damage your SEO, step-by-step methods to find every broken link on your site, how to fix them correctly, how to recover lost backlink equity, and how to use broken link building as a proactive growth strategy.

Section 1: What Are Broken Links?
A broken link , also called a dead link , is a hyperlink that no longer leads to its intended destination. When a user or search engine crawler follows a broken link, they receive an HTTP error response instead of the expected page content.
The Most Common HTTP Error Responses from Broken Links
HTTP Status | Name | Meaning | SEO Impact |
404 | Not Found | The page does not exist at this URL | Highest , crawl waste, lost equity |
410 | Gone | The page has been permanently removed | High , communicates intentional removal |
500 | Server Error | Server failed to fulfil the request | High , affects crawlability and UX |
503 | Service Unavailable | Server temporarily overloaded | Medium , temporary but recurrent issues hurt |
301 Loop | Redirect Loop | Two or more pages redirect to each other | High , crawlers abandon after 3-5 hops |
302 to 404 | Temp Redirect to Dead | Redirects to a page that no longer exists | High , equity not passed, crawl wasted |
The 4 Categories of Broken Links
01 | Internal Broken Links | Links within your own website pointing to pages that no longer exist on your domain. These directly damage crawl budget, internal link equity flow, and user experience. The most immediately fixable category. |
02 | External Broken Links (Outbound) | Links from your pages pointing to external websites that have changed or deleted their content. These harm your user experience and signal poor site maintenance to both users and Google. |
03 | Broken Inbound Links (Backlinks) | Links from other websites pointing to pages on your site that no longer exist. These represent lost authority , a high-value backlink pointing to a 404 page passes zero PageRank to your live content. |
04 | Broken Image Links | Images with broken src attributes or image files that have been moved or deleted. These degrade user experience, consume crawl budget on 404 requests, and remove visual content that supports keyword relevance. |
Section 2: How Broken Links Damage Your SEO
Understanding the precise mechanisms by which broken links harm your rankings is essential to prioritising your fix efforts. The damage operates through four distinct pathways:
Damage 1: Crawl Budget Waste
Every website has a crawl budget , the number of pages Googlebot will crawl on your site within a given timeframe. When Googlebot follows a broken internal link and receives a 404 response, it has spent crawl budget without discovering any new content. For large sites with thousands of pages, significant broken link counts mean important pages may go undiscovered and unindexed simply because Googlebot exhausted its budget on dead URLs before reaching them.
Pro Insight: For small sites (under 500 pages), crawl budget is rarely a critical constraint. For sites with 1,000+ pages, every unnecessary 404 crawl represents a real opportunity cost. Google’s own documentation confirms that ‘reducing URLs that return error codes will help Google crawl your site more efficiently.’ |
Damage 2: Internal Link Equity Fragmentation
Your internal links distribute PageRank throughout your site, directing authority from high-performing pages to pages you want to rank. When an internal link points to a broken URL, that authority flow is terminated. Instead of boosting an important page, the link equity disappears into a 404 response. For pages that rely on internal link equity to supplement weaker external backlink profiles, this can directly suppress rankings.
Damage 3: Lost Backlink Authority
This is the highest-impact broken link problem for off-page SEO. When an external website links to a page on your site that you have since deleted or moved without a redirect, that backlink is broken. The linking domain’s authority and the topical relevance signal of the anchor text are completely wasted , they contribute nothing to your rankings. A single broken backlink from a high-DR domain (Domain Rating 70+) represents a significant and recoverable SEO loss.
Ahrefs’ research has found that the average website loses approximately 5-6% of its backlinks every year simply through link rot , pages moving, redirects expiring, and content being deleted. Without active monitoring, this equity erosion compounds annually.
Damage 4: User Experience Signals
Google uses user behaviour signals , bounce rate, time on site, pogo-sticking , as indirect ranking factors. A user who clicks an internal link and hits a 404 page will almost always bounce immediately. If this happens frequently, Google’s understanding of your site’s quality degrades. For e-commerce sites where broken product pages are common, this can directly suppress both organic and paid search performance.
Section 3: How to Find Broken Links , Complete Tool Guide
Finding every broken link on your site requires a combination of tools, as each surfaces different types of broken links from different perspectives. Here is a complete workflow using the four most effective tools:
Method 1: Screaming Frog (Best for Internal Broken Links)
Screaming Frog is the industry-standard crawler for technical SEO audits and the most thorough tool for finding internal broken links at scale.
Screaming Frog , Broken Link Audit Workflow
Step 1: Open Screaming Frog > Enter your domain > Start crawl Step 2: Wait for crawl to complete (1,000 pages takes ~5-10 min) Step 3: Navigate to: Response Codes > Client Error (4xx) This shows all URLs on your site returning 4xx errors
Step 4: Navigate to: Response Codes > 4xx > Inlinks tab This shows WHICH pages contain broken links , the source (linking page) and anchor text are listed
Step 5: Export to CSV: Reports > Response Codes > Client Error (4xx) Column: Address = broken URL | Inlinks = pages linking to it
Step 6: Navigate to: External Links > Filter: 4xx This surfaces broken OUTBOUND links to external sites
Free version: crawls up to 500 URLs Paid version (£149/year): unlimited URLs , essential for large sites |
Method 2: Google Search Console (Best for Google-Confirmed 404s)
Google Search Console shows you the exact broken URLs that Googlebot has encountered when crawling your site. This is the most authoritative source because it reflects what Google itself is experiencing.
Google Search Console , Broken Link Audit Workflow
Step 1: Open GSC > Pages (Coverage report) Step 2: Filter: ‘Not indexed’ > Select: ‘Not found (404)’ This lists every URL Google tried to crawl that returned 404
Step 3: Click any URL to see: , Last crawl date , Referring pages (which pages link to this broken URL) , Whether it was ever indexed
Step 4: Navigate to: Links > Internal links This shows pages with fewest internal links , often orphaned after other pages were redirected without updating internal links
Step 5: Export the 404 report for your fix prioritisation spreadsheet
Key advantage: GSC confirms which 404s Google actually cares about Low-traffic 404s may be deprioritised vs high-value broken pages |
Method 3: Ahrefs (Best for Broken Inbound Backlinks)
Ahrefs is the essential tool for finding broken inbound links , backlinks from other sites pointing to 404 pages on your domain. These are the highest-priority broken links to fix because they represent recoverable link equity.
Ahrefs , Broken Backlink Recovery Workflow
Step 1: Ahrefs > Site Explorer > Enter your domain Step 2: Left menu: Pages > Best by Links Filter: ‘404 not found’ This shows your deleted/moved pages that still have backlinks Sort by: Referring Domains (highest first = highest priority)
Step 3: For each broken page: Click ‘Backlinks’ to see which external domains link to it Note the DR (Domain Rating) of each linking domain Backlinks from DR 40+ are high priority to recover
Step 4: Also check: Site Explorer > Backlinks Filter: Broken (shows all backlinks pointing to 404 pages) Export this full report for your redirect planning
Step 5: Create 301 redirects from broken URLs to: , The new URL if the page was moved , The closest topically relevant live page , The homepage as a last resort (only if no relevant page exists) |
Method 4: SEMrush Site Audit (Best All-in-One Overview)
SEMrush’s Site Audit tool provides a comprehensive broken link report as part of its full technical audit, making it useful for getting a high-level view of broken link severity before diving into detailed tool-specific workflows.
SEMrush Site Audit , Broken Link Overview
Step 1: SEMrush > Site Audit > Set up project for your domain Step 2: Run full audit (schedules can be set weekly or monthly) Step 3: Navigate to: Issues > Errors Look for: ‘X broken internal links’ ‘X pages returned 4xx status code’ ‘X broken external links’
Step 4: Click each issue type to see full URL lists Export and prioritize by page authority / traffic
Step 5: SEMrush Backlink Audit tool: Left menu: Backlink Audit > set up project Filter: Lost links > shows recently broken backlinks Use ‘Outreach’ feature to contact linking sites for reclamation |
Tool Comparison for Broken Link Audits
Tool | Best For | Internal Links | Backlinks | Free Tier |
Screaming Frog | Full site crawl , all internal broken links | Excellent | No | 500 URLs |
Google Search Console | Google-confirmed 404s and crawl errors | Good | Partial | Free (full) |
Ahrefs | Broken backlinks / lost inbound equity | Good | Excellent | Limited |

Moz Pro | Domain-level broken link overview | Moderate | Moderate | 30-day trial |
W3C Link Checker | Quick spot-check of small sites | Basic | No | Free |
Section 4: How to Fix Broken Links , Step-by-Step
Once you have identified your broken links, fixing them requires different approaches depending on the type of break. Here is the complete fix workflow for each scenario:
Fix Type 1: Internal Links Pointing to Moved or Renamed Pages
The cleanest fix for internal broken links is to update the link source to point to the correct, current URL. This preserves full link equity without relying on a redirect.
- 1. Open the linking page in your CMS (WordPress, Webflow, etc.)
- 2. Find the broken anchor link , update the href to the correct current URL
- 3. Save and republish the page
- 4. Verify the fix in Screaming Frog by recrawling the linking page
- 5. Submit the updated page for recrawling via Google Search Console
Fix Type 2: Permanently Deleted Pages with Backlinks , 301 Redirect
If a page has been permanently deleted but has valuable backlinks pointing to it, implement a 301 permanent redirect to the most relevant live page. This recovers the majority of lost link equity.
301 Redirect Implementation , Apache (.htaccess)
# Single page redirect Redirect 301 /old-page-url/ /new-page-url/
# Redirect deleted blog post to category page Redirect 301 /blog/old-post-title/ /blog/seo-tips/
# Wildcard redirect for an entire deleted section RedirectMatch 301 ^/old-services/(.*)$ /services/$1
──────────────────────────────────────────────────── 301 Redirect Implementation , Nginx
# Single page redirect rewrite ^/old-page-url/$ /new-page-url/ permanent;
# Redirect entire directory rewrite ^/old-blog/(.*)$ /blog/$1 permanent;
──────────────────────────────────────────────────── 301 Redirect , WordPress (via Rank Math or Yoast)
Rank Math: SEO > Redirections > Add New Source URL: /old-page-url/ Destination: /new-page-url/ Redirect Type: 301 Permanent
Yoast Premium: SEO > Redirects > Add redirect Type: 301 Old URL: /old-page-url/ New URL: /new-page-url/ |
Fix Type 3: Broken External Outbound Links
For links from your pages pointing to external sites that have gone offline or changed their URLs, you have three options in priority order:
- 6. Find the new URL for the resource (check Wayback Machine at web.archive.org) and update the link to the current address
- 7. Replace the link with an alternative high-quality source covering the same information
- 8. Remove the link entirely and rephrase the referencing sentence to not require an external citation
Automation Tip: For WordPress sites with many external links, the Broken Link Checker plugin (by WPMU Dev) automatically scans all posts and pages for broken outbound links and alerts you by email when new ones are detected. Set it to run weekly for continuous monitoring. |
Fix Type 4: Broken Image Links
Broken image links are typically caused by images being deleted from the media library, files being renamed, or the image CDN URL changing. Fix workflow:
- 9. In Screaming Frog, navigate to: Images > filter 4xx , this lists all broken image src attributes
- 10. For each broken image, identify whether the file still exists (just at a different path) or has been deleted
- 11. If the file exists: update the src attribute in the HTML or CMS to the correct path
- 12. If the file has been deleted: re-upload the original file (check backups) or replace with an equivalent image
- 13. For images still referenced in old posts but moved to a CDN: implement a 301 redirect from the old path to the new CDN URL
The 301 Redirect Cascade Warning When implementing 301 redirects to fix broken links, avoid creating redirect chains , where URL A redirects to URL B which redirects to URL C. Each hop in a redirect chain loses approximately 10-15% of the passed link equity. Always redirect directly to the final destination URL. If a redirect chain already exists, update the origin redirect to point directly to the endpoint. |
Section 5: Recovering Broken Backlinks , The Link Reclamation Process
Broken inbound backlinks represent your highest-value broken link recovery opportunity. When another website links to a page on your site that no longer exists, you have already earned the link , you just need to make it work again. Here is the full reclamation process:
Tier 1: Self-Service Recovery via 301 Redirects
For the majority of broken backlinks, the fastest and most effective fix is implementing a 301 redirect from the broken URL to your most relevant live page. You do not need the linking site to do anything , the redirect automatically passes the link equity to your live content. This is the first action you should take for every broken inbound URL identified in Ahrefs.
Prioritise redirects by: (1) number of referring domains pointing to the broken URL, (2) DR of the linking domains, (3) topical relevance of the linking pages to your live content. A broken URL with 15 referring domains from high-DR sites should be redirected immediately.
Tier 2: Outreach for Reclamation (High-Value Links Only)
For broken backlinks from very high-DR sites (DR 60+) where the 301 redirect alone may not fully recover the situation , especially if the linking page’s context has become confusing due to the broken link , a brief outreach email to the webmaster requesting an anchor update to your new URL is worthwhile.
Subject: Quick fix for a broken link on [their domain]
Hi [Name],
I was reading your excellent article on [topic] at [their URL] and noticed one of the links appears to be broken.
The link pointing to [your old broken URL] now returns a 404. We have actually moved that content to: [your new URL]
Would you be willing to update the link? The new page covers [brief description of content] in more depth than the original.
Either way, thank you for the mention , it is appreciated.
Best regards, [Your name] [Company] | [Website] |
Tier 3: Content Replacement for Expired Links
If your broken backlinks point to URLs where the original content no longer exists and there is no relevant replacement on your site, consider creating a new piece of content specifically designed to earn those links legitimately. Publish the content at the old URL (if possible) or at a new URL and redirect the old one to it. This rebuilds the link’s context and maximises equity recovery.
Section 6: Broken Link Building , Turning Others' Problems Into Your Backlinks
Broken link building is the proactive, outbound application of broken link SEO: you find broken links on other high-authority websites, identify what content they were linking to, create equivalent or superior content on your site, and contact the webmaster to suggest replacing the broken link with a link to your resource.
It is one of the most Google-compliant and effective link building strategies available because it provides genuine value to the linking site , you are helping them fix a problem, not just asking for a favour.
Step-by-Step Broken Link Building Process
- 14. Identify resource pages and authoritative content hubs in your niche using Google searches: 'keyword intitle:resources', 'keyword inurl:links', 'keyword "useful links"'
- 15. Crawl those pages with Screaming Frog or Check My Links (Chrome extension) to identify broken outbound links
- 16. For each broken link, find the original content using the Wayback Machine (web.archive.org) to understand what the resource covered
- 17. Check if you already have equivalent content on your site , if yes, go directly to outreach. If no, create a resource that matches or exceeds the quality of the original
- 18. Contact the webmaster with a short, friendly email: note the broken link, provide your replacement URL, and briefly explain why your content is a suitable replacement
- 19. Follow up once after 7-10 days if no response , do not send more than two emails
Scaling Broken Link Building with Ahrefs
Ahrefs , Competitor Broken Link Building Workflow Step 1: Ahrefs > Site Explorer > Enter a competitor domain Step 2: Backlinks > Filter: Broken This shows external sites linking to your competitor’s 404 pages These sites are actively hosting broken links , prime targets Step 3: Export the list > prioritise by DR of linking domain Step 4: For each high-DR linking page: Visit the page > confirm the broken link exists Check Wayback Machine for the original linked content Identify your closest matching content (or create it) Step 5: Outreach using the email template above Tip: Target competitor 404 pages that have 5+ referring domains , these pages had significant content value and multiple sites still link to them, giving you multiple outreach targets per asset |
Broken link building is particularly effective in: resource-heavy niches (SEO, digital marketing, finance, health), industries with frequent content churn (news, technology, legislation), and academic or government-adjacent niches where old .edu or .gov pages frequently break. A single well-placed broken link opportunity can win links from 5-15 sites simultaneously. |
Section 7: Ongoing Broken Link Monitoring
A one-time broken link audit is valuable but insufficient. Broken links accumulate continuously as you update your site and as external websites change their content. Effective broken link management requires ongoing monitoring:
Monitoring Frequency | Action | Tool |
Weekly | Check GSC Coverage report for new 404 errors | Google Search Console (free) |
Monthly | Full site crawl for internal and external broken links | Screaming Frog |
Monthly | Check for newly broken inbound backlinks | Ahrefs Site Explorer |
Quarterly | Full broken link audit + prioritised fix sprint | Ahrefs + Screaming Frog + GSC |
On any major URL change | Verify 301 redirects are in place before publishing | Screaming Frog + manual test |
On content deletion | Check for internal links pointing to the deleted page | GSC + Screaming Frog |

Broken Links: Do's and Don'ts
DO | DON’T |
Audit broken links monthly , they accumulate continuously without monitoring | Ignore 404 errors in Google Search Console as ‘just technical noise’ |
Implement 301 redirects immediately for any deleted page with backlinks | Delete pages without checking their backlink profile first in Ahrefs |
Update internal links to point directly to current URLs , not through redirects | Leave 301 redirect chains in place when direct links are always better |
Prioritise broken backlink recovery by referring domain count and DR | Treat all 404s equally , focus effort on high-value broken pages first |
Use Wayback Machine to understand what original broken link content covered | Redirect all 404s to the homepage , only do this as a last resort for low-value pages |
Combine Screaming Frog (internal) + Ahrefs (backlinks) + GSC for full coverage | Rely on a single tool , each surfaces different categories of broken links |
Set up automated weekly GSC monitoring for new 404 errors | Run a one-time audit and consider broken links permanently resolved |
Use broken link building to proactively earn backlinks from competitor gaps | Only fix broken links defensively , the offensive broken link building opportunity is significant |
