How to Fix Broken Links in SEO: 6 Proven Steps That Work
Broken links are silent. They accumulate over months without triggering any obvious alert in your rankings dashboard. But they are steadily doing three things at once: wasting Googlebot’s crawl allocation on dead ends, draining PageRank away from your live content, and destroying the user experience of anyone who clicks them.
The most frustrating part: most broken link problems on established sites are not caused by negligence. They form naturally. Content gets deleted. URLs get restructured. External sites go dark. Without a systematic process to find them, the damage compounds invisibly.
This six-step guide gives you the complete process, whether you have never run a broken link audit before, recently restructured your URLs, or want to recover link equity from backlinks pointing to dead pages you did not know existed.

What Broken Links Are Actually Costing You
PageRank leakage is immediate and measurable. Every internal link distributes ranking authority. A link pointing to a 404 URL sends that authority nowhere. Fix the link or redirect the dead URL and PageRank flow restores immediately.
Crawl budget waste compounds over time. On large sites with hundreds of broken links, Googlebot uses a significant portion of its crawl allocation on fruitless requests. Each request on a broken URL is a missed opportunity to re-crawl and re-index a live page with valuable content.
Broken backlinks are an unnoticed recovery opportunity. When an external site links to a URL you deleted without redirecting, all that link equity is gone. A 301 redirect from the dead URL to your best live equivalent recovers it at the cost of one redirect rule. This is one of the highest-ROI technical fixes available.
How to Find Every Broken Link
Screaming Frog (Most Comprehensive Method)
Run a full site crawl. Go to Reports, then All Inlinks, then Export to CSV.
Open the export. Filter the “Status Code” column for 404. Every remaining row is a broken link: source page, broken destination URL, anchor text, internal or external.
This is the complete broken link map for your entire site generated automatically.
Google Search Console
Indexing, then Pages, filter by “Not found (404).” These are URLs Google attempted to crawl and found dead. Some are broken internal links. Others are broken backlinks from external sites.
Ahrefs or Semrush
Both include broken internal link reports in their site audit modules with automated weekly updates. Configure notifications to receive alerts when new broken links appear.
How to Fix Broken Links in SEO: 6 Steps
Step 1: Build the Complete Broken Link Map
Export the Screaming Frog All Inlinks CSV filtered by 404. Export the GSC 404 URL list. Combine into one master spreadsheet with columns: Source Page, Broken URL, Link Type (internal/external/backlink), Fix Method, Fix Owner, Deadline, Status.
Step 2: Categorise by Link Type
Internal broken links: your pages linking to your own dead pages. Fix with redirects or source link updates.
External broken links (outbound): your pages linking to dead pages on other sites. Fix by removing or replacing with a current source.
Broken backlinks: external sites linking to dead pages on your domain. Fix with 301 redirects. This is link reclamation.
Step 3: Fix Internal Broken Links
Option A: 301 redirect from the dead URL to the most relevant live page. Best when the dead URL has external backlinks or ranking history. The redirect preserves any equity the dead URL accumulated.
Option B: Update the source link directly. Edit the page containing the broken link and change the href to the correct live URL. Cleaner than a redirect: no extra hop in Googlebot’s crawl path. Use this when no external backlinks exist for the dead URL.
Option C: Remove the link. When no relevant live equivalent exists and the link had no external equity, deletion is the cleanest fix.
Fix order: navigation links first, then pillar content, then category pages, then body content. This priority reflects the PageRank impact of each location.
Step 4: Fix Outbound Broken Links
For each broken external link in your content:
- Search for the current version of the resource at the original domain
- Check archive.org for the archived version to understand what was originally referenced
- Find a current, reliable alternative covering the same topic
- Replace the link or remove it
Priority: fix outbound broken links on your highest-ranking pages first. A broken external link on a page ranking position 1 is a credibility problem on your most visible content.
Step 5: Recover Broken Backlinks
This step recovers link equity that already belongs to you but is currently being wasted.
Find broken backlinks:
- Ahrefs: Site Explorer, then Backlinks, filter by HTTP code 404
- Semrush: Backlink Audit, filter by broken pages
Fix each one: Create a 301 redirect from the dead URL to your most contextually relevant live page. The external backlink now passes its full link equity to your live content.
You did not earn a new link. You recovered one you already had but were losing. For high-authority backlinks pointing to dead pages, this single step can produce ranking improvements within weeks of Googlebot re-crawling the redirected URL.
Step 6: Verify Fixes and Set Up Monitoring
Re-run a Screaming Frog crawl. Confirm the 4XX count has dropped.
Use GSC URL Inspection to verify the most important fixed pages return 200 status.
Set up weekly automated monitoring in Semrush or Ahrefs. Configure email alerts for new 4XX errors. Broken links form constantly. Monthly monitoring catches them before they accumulate.

Frequently Asked Questions
Do broken links cause a Google penalty?
No direct penalty. The damage is indirect: leaked PageRank, wasted crawl budget, and negative user experience signals. Sites with zero broken internal links consistently outperform those with accumulating 404 errors.
Is it better to redirect a dead URL or update the source link?
Update the source link when possible. No extra redirect hop means cleaner PageRank flow and a faster crawl path. Use a 301 redirect when external backlinks point to the dead URL.
How do I find external backlinks pointing to 404 pages?
Ahrefs Site Explorer or Semrush Backlink Audit, filtered by broken target pages. Every high-authority backlink to a dead URL is a link reclamation opportunity recoverable with a single 301 redirect.
