Broken links are a normal part of website maintenance, but they can create a poor user experience and make site audits harder to trust. A broken link checker helps you find URLs that return errors, redirect incorrectly, or point to pages that no longer exist so you can clean up your site in a structured way.
For SEO audits, this matters because broken internal links can waste crawl paths, frustrate visitors, and weaken the flow between important pages. Used properly, a broken link checker is not a magic fix, but it is a practical SEO tool that supports better technical decisions, cleaner content, and more reliable site health checks.
What a broken link checker does in an SEO audit
A broken link checker scans pages and reports links that are no longer working. In most audits, the main goal is to identify links that return 404 errors, 410 responses, server errors, or problematic redirects. You can use the findings to repair links, update content, or remove outdated references.
This is useful for all kinds of sites, including blogs, local business websites, ecommerce stores, and WordPress sites with older content. It also helps when you are reviewing a site after a redesign, migration, theme change, or content pruning exercise.
Broken link data should be read alongside other SEO tools. For example, Google Search Console can show indexing and crawl issues, while a crawler tool can reveal how broken URLs sit within your site structure. If you are running a broader audit, a free website SEO audit can help you bring broken links into the wider technical SEO picture.
How to use broken link checker tools effectively
Start with your most important pages first. Homepage links, navigation links, service pages, category pages, and high-traffic content should be checked before older archive pages. These are the areas where broken links are most likely to affect users and search engines.
Then review the type of broken link:
- Internal links that point to your own pages
- External links that point to third-party websites
- Image or file links that may be missing or moved
- Redirect chains that create unnecessary hops
After that, decide on the right fix. Internal links should usually be updated to the correct live URL, redirected carefully, or removed if the page no longer exists. External links may need replacing with a more current source. If a page was moved, a clean 301 redirect is often better than leaving visitors at a dead end.
How broken links fit into a wider SEO audit workflow
Broken link checking is most useful when it sits inside a complete audit rather than being treated as a standalone task. A typical workflow may include a website crawler, Google Search Console, Google Analytics 4, and a speed tool such as PageSpeed Insights or Core Web Vitals reporting. Together, these tools help you understand whether broken links are affecting crawlability, engagement, and overall site quality.
For example, if a product page has strong search impressions but weak engagement, a broken internal link from a category page may be one reason users do not reach it. If a content hub has many old articles, checking for broken links can also support content optimisation by keeping references fresh and trustworthy.
Broken links can also matter for reporting. When you present audit findings in Looker Studio or another reporting platform, it is easier to prioritise fixes if the broken link data is grouped by page type, template, or section of the site. That makes the SEO work more actionable for developers, editors, and clients.
Choosing the right tool for the job
There are many SEO tools that can find broken links, from free browser-based checkers to more advanced crawler platforms. The right choice depends on website size, budget, technical skill, and how often you need to audit.
Free tools are often enough for small sites, occasional checks, or quick spot audits. They are useful, but they may have limits on crawl depth, export options, or the number of URLs you can scan. Paid tools can be a better fit for larger sites, agencies, ecommerce stores, and technical SEO teams that need scheduled crawls, detailed exports, and repeatable workflows.
If you want a broader technical view, tools such as Screaming Frog SEO Spider are commonly used for crawling and site audits, including broken link discovery. The important point is not to choose based on name alone, but on whether the tool fits your site size, reporting needs, and team process.
Best practices for fixing broken links without creating new issues
Not every broken link should be fixed in the same way. The goal is to preserve user experience and search clarity without creating redirect clutter or misleading signals.
- Update internal links to the most relevant live page.
- Use 301 redirects only when a replacement page genuinely exists.
- Avoid redirect chains and loops.
- Check anchor text after updating links so it still matches the destination.
- Review older content regularly, especially after site migrations or product changes.
One common mistake is to ignore external broken links because they do not belong to your domain. They still affect trust and usability, especially on editorial pages, resource lists, and blog posts. Another mistake is deleting broken URLs without checking whether they have internal links, backlinks, or search demand. Sometimes a redirected replacement is better than removal.
Using broken link checks with other SEO tools
Broken link audits become more valuable when they are combined with other SEO tools. Keyword research tools can show which pages deserve more attention. Rank tracking tools can help you monitor whether important pages are still visible after fixes. Backlink checker tools can identify whether a removed page still has links from other sites, which may make a redirect worthwhile.
Content optimisation tools and schema markup tools can help you improve the pages you keep, while local SEO tools can be useful for business location pages that need clean internal navigation. For WordPress users, SEO plugins can help manage on-page updates, but they do not replace the need to check links manually or with a crawler. In ecommerce SEO, broken links often appear in discontinued products, seasonal collections, and filtered category pages, so regular audits are worth planning.
If you are trying to improve search visibility in a measured way, broken link checking is one of the practical tasks that supports the bigger picture. Backlink Works also publishes SEO education that can help teams build more consistent audit habits, but the main value still comes from using the right tool for the task and following a repeatable process.
Conclusion
A broken link checker is a straightforward but important part of SEO site audits. It helps you clean up technical errors, improve usability, and keep content structures tidy across blogs, ecommerce sites, and business websites. Used alongside Google Search Console, analytics, crawl data, and performance tools, it becomes part of a more complete SEO workflow.
The best results come from regular checking, sensible fixes, and clear prioritisation. Broken links alone will not transform performance, but fixing them helps create a healthier site that is easier for visitors and search engines to navigate.
Frequently Asked Questions
How often should I run a broken link check?
For active websites, monthly checks are sensible. Larger sites, stores, and publishing sites may need more frequent audits.
Do broken links always harm SEO?
Not always, but they can create crawl waste, poor user experience, and weaker internal navigation if left unresolved.
Should I fix external broken links on my site?
Yes, if they appear in your content. Replace them with a live, relevant source or remove them if no good alternative exists.
Can Google Search Console find broken links?
It can surface crawl and indexing issues, but a dedicated broken link checker or crawler usually gives a more complete view of site-wide link problems.
