Broken Links Hurting SEO: How to Find & Fix Them (Before They Kill Your Rankings)

If you’re investing in SEO and digital marketing but still not seeing the rankings you expect, there’s a good chance broken links are silently hurting your SEO performance.

Broken links don’t just frustrate users – they waste crawl budget, weaken your internal linking, and can send negative quality signals to search engines. Leading SEO resources including Google Search Central and industry authorities like Moz and Ahrefs all highlight how important clean, functional links are for a healthy website.

Below is a practical, SEO-optimised guide on broken links hurting SEO – what they are, why they matter, how to find them, and what to do about them.

What Are Broken Links?

A broken link (also called a dead link) is any hyperlink that leads to a page that cannot be loaded, usually returning an HTTP error like 404 Not Found or 500 Server Error.

According to Moz’s guide to broken links, broken links are common on older websites where:

Pages were moved or deleted without proper redirects
URLs were changed (e.g., during redesigns or CMS migrations)
External websites you link to removed or changed their content

Broken links can appear in:

Navigation menus
Blog posts and landing pages
Footer links
Image links or buttons
Sitemaps

Why Broken Links Hurt SEO

1. Poor User Experience

Google has repeatedly emphasized that good user experience is central to search performance. In its documentation on SEO basics, Google Search Central notes that websites should make it easy for users to navigate and find relevant content.

When visitors click a link and land on a 404 error page, they are likely to:

Leave the site quickly (high bounce rate)
View fewer pages
Lose trust in your brand

While Google has stated that a few 404 errors won’t directly cause penalties, Google’s John Mueller has clarified that they can indirectly affect performance because they break user journeys and internal paths across the site, making it harder for users and crawlers to discover key content (source: Google Search Central office hours, referenced in this summary by Ahrefs).

2. Wasted Crawl Budget & Indexation Issues

Googlebot and other search engine crawlers have a limited amount of resources they allocate to each site, often called crawl budget.

In Google’s guidance on crawl budget, they explain that unnecessary or low‑value URLs (including broken or duplicate ones) can waste crawling resources, especially on larger sites (Google Search Central – Crawl Budget).

If crawlers keep hitting dead links, they spend time on pages that:

Will never rank
Don’t help users
Don’t pass PageRank or topical relevance

This can delay or reduce how often your important pages are crawled and updated in the index.

3. Loss of Link Equity (PageRank)

Links are still one of the strongest ranking signals. When a page with backlinks is removed without a proper redirect, the link equity (PageRank) pointing to that URL is largely wasted.

Ahrefs shows in their detailed guide to 404 pages that backlinks pointing to non‑existent URLs don’t benefit your live pages unless you implement redirects appropriately (Ahrefs – 404 Guide). This means:

Internal links to missing pages break your internal link structure
External backlinks to deleted URLs don’t help your current content
Your overall domain authority and topical authority are weakened

4. Weaker Internal Linking & Topical Signals

Internal links help search engines understand:

Which pages are most important
How topics and subtopics are connected

When internal links are broken, that structure collapses. Moz notes that broken internal links are usually more harmful than broken external links because they directly disrupt how your own content is crawled and understood (Moz – Broken Links).

For SEO‑critical pages like service pages, category pages, and cornerstone blog content, broken internal links can reduce their discoverability and importance in Google’s eyes.

Types of Broken Links That Hurt SEO the Most

Broken Internal Links
- Links between your own pages that return 404 or 500 errors
- Especially harmful on menus, sidebars, and key content hubs
Broken Links on High‑Traffic Pages
- Dead links from your homepage, popular blog posts, or landing pages
- These break important click paths and lower user satisfaction
Broken Backlink Targets (Deleted Pages With Links)
- Pages that had external backlinks but were removed or renamed
- Without 301 redirects, that authority is effectively lost (Ahrefs – Lost Link Equity Example)
Broken Canonical or hreflang Targets
- Misconfigured canonical tags that point to non‑existent URLs
- Hreflang tags pointing to missing pages in other languages/regions
- Google’s documentation on canonicalization stresses that canonical URLs should resolve properly

How to Find Broken Links on Your Website

1. Use Google Search Console

Google Search Console (GSC) is a free tool from Google. In the Page Indexing and Crawl Stats reports, you can see URLs returning 404 or other errors that Google’s crawler encountered (Google Search Central – Search Console Overview).

Steps:

Verify your site in Google Search Console
Go to Indexing → Pages
Filter for errors like “Not found (404)”
Export the list of affected URLs

These are URLs Google tried to crawl but couldn’t access.

2. Run a Full Crawl with Desktop Tools

SEO crawling tools simulate how a search engine crawls your website. They are highly effective for detecting broken internal and external links.

Common tools:

Screaming Frog SEO Spider – A widely‑used desktop crawler that lists response codes and broken links (Screaming Frog – Features).
Sitebulb – Another desktop SEO auditor that highlights broken links, redirect chains, and orphan pages (Sitebulb – Website Crawler).

Typical workflow:

Enter your domain (e.g., `https://silastnkoana.co.za/`) into the crawler
Let the tool crawl all accessible URLs
Filter by Status Code = 4xx / 5xx
Export lists of inlinks (where those URLs are linked from)

3. Use Online SEO Audit Platforms

Cloud‑based SEO tools help you detect broken links and monitor them over time:

Semrush Site Audit – Automatically scans for broken internal and external links, and reports them under “Errors” (Semrush Site Audit).
Ahrefs Site Audit – Identifies 404 errors, broken redirects, and orphan pages, and shows where broken links live (Ahrefs – Site Audit Overview).

These platforms are particularly useful if you manage multiple client sites or larger projects.

4. Check External Broken Links (Backlinks to 404 Pages)

When other websites link to pages that no longer exist on your site, you’re losing valuable authority and referral traffic.

Tools such as Ahrefs and Semrush can show which backlinks point to 404 pages:

In Ahrefs, the Best by Links and Broken backlinks reports highlight URLs that return 404 but have inbound links (Ahrefs – Broken Backlinks Report).

This is a crucial step in recovering and preserving link equity.

How to Fix Broken Links (Without Hurting SEO Further)

Once you’ve identified where broken links exist, you need a structured plan to fix them.

1. Restore or Redirect Important Content (301 Redirects)

If a deleted or changed URL:

Had quality backlinks
Received organic traffic
Was important for conversions

…then you should either restore the content or implement a 301 redirect to the most relevant alternative page.

Google notes that 301 redirects are the preferred way to permanently move content while preserving ranking signals (Google Search Central – Site Moves).

Key guidelines:

Redirect to a closely related page (same intent/topic)
Avoid redirecting everything to the homepage (can confuse algorithms and users)
Minimise redirect chains (301 → 301 → 301), which slow crawling and dilute signals

2. Update Internal Links to Point to Live URLs

After setting redirects, you should still update internal links to reference the final, correct URLs directly:

Replace outdated URLs in navigation, body content, sidebars, and footers
Update image links and CTAs too
Use crawling tools to confirm there are no remaining internal 4xx links

This makes your internal structure cleaner and can improve crawl efficiency.

3. Remove or Replace Broken External Links

For outbound links that go to dead pages on other websites:

If there is a similar or updated resource, change the URL to that
If no good replacement exists, remove the link or the reference from the content

According to Moz’s linking best practices, outbound links to high‑quality, relevant pages can help user experience and context, but broken outbound links create a poor user experience and should be cleaned up.

4. Custom 404 Page for Unavoidable Errors

No matter how well you maintain your site, some 404s are inevitable (e.g., mistyped URLs). Google recommends implementing a helpful custom 404 page to retain users and guide them elsewhere on the site (Google Search Central – 404 Page Recommendations).

A good custom 404 page includes:

Clear message that the page can’t be found
Links to popular categories or pages
A site search box
Consistent branding with the rest of the site

While a 404 page alone doesn’t fix SEO issues, it mitigates user frustration when broken links do appear.

Preventing Broken Links from Hurting SEO in the Future

To keep broken links from creeping back and harming your SEO:

Adopt a URL Strategy & Governance
- Avoid unnecessary URL changes
- Plan redirects when restructuring the site or changing CMS
Set Up a Regular Technical SEO Audit
- Use tools like Screaming Frog, Ahrefs Site Audit, or Semrush Site Audit on a monthly or quarterly basis
- Monitor new 4xx/5xx errors and fix promptly
Check Internal Linking After Content Updates
- Whenever pages are removed or renamed, update referring internal links
- Maintain a list of “core pages” and ensure they’re always reachable via key navigation paths
Monitor Google Search Console
- Review new coverage errors and 404s reported by Google
- Fix patterns (e.g., recurring parameter issues, outdated sitemaps)
Keep Sitemaps & Navigation Clean
- Ensure XML sitemaps only list live, canonical URLs (Google – Sitemaps)
- Remove old menu items and footer links pointing to retired content

Why This Matters for SEO & Digital Marketing Performance

Whether you focus on organic search, paid campaigns, or broader digital marketing, broken links directly undermine results:

Lower organic visibility because internal authority and crawl efficiency drop
Lost conversions when users hit errors instead of landing pages
Reduced ROI on content and link building when high‑value links point to dead URLs
Damaged brand perception when prospects experience a “broken” website

Industry resources like Moz and Ahrefs consistently emphasise that fixing technical issues such as broken links is foundational to improving rankings and maintaining long‑term SEO health.

If you rely on search visibility to drive leads and sales, don’t ignore the silent impact of broken links hurting SEO. Identifying and fixing them – and then preventing them going forward – is one of the highest‑leverage technical actions you can take to stabilise and grow your organic performance.
