Broken links are a normal part of website growth, especially when pages are updated, removed, merged, or moved. The challenge is not just finding them, but understanding which broken links matter most for search visibility, user experience, and crawl efficiency.
Google Search Console and GA4 can help you spot these issues from two different angles. Search Console shows how Google discovers and crawls your pages, while GA4 helps you see where users encounter broken journeys and where engagement drops after a bad click. Used together, they give a more complete view than either tool alone.
Why broken link tools matter for SEO audits
Broken links can affect internal linking, indexation, and user experience. If important pages are linked from menus, content, or product categories but the destination no longer exists, both users and search engines may struggle to move through the site efficiently.
For SEO audits, broken link checks are useful because they help identify:
- Internal links pointing to deleted or changed pages
- External links that no longer resolve
- Redirect chains or broken redirect targets
- Orphaned pages that are no longer properly connected
A good audit usually combines free SEO tools, website crawler tools, and analytics data. Google Search Console and GA4 are especially valuable because they are free, widely used, and already connected to your site’s performance data.
How Google Search Console helps find broken links
Google Search Console is one of the most useful free SEO tools for technical SEO. It does not give every broken link in the site, but it can show crawl and indexing problems that often point to broken URLs or destination issues.
Start by checking the pages that Google reports as not indexed, crawl errors, or pages with soft 404 behaviour. These reports can reveal URLs that are missing, returning errors, or behaving like empty pages. If a page is being linked internally but no longer exists, Search Console can help you see the problem from Google’s point of view.
It also helps to inspect important pages manually. If a page should be live but Search Console is not indexing it as expected, check whether internal links still point to the correct URL, whether a redirect is in place, and whether the page returns the right status code.
For a broader technical review, many teams use Search Console alongside a crawler. If you need a structured starting point, a free website SEO audit can help highlight common issues before you dig deeper.
How GA4 helps you spot broken user journeys
GA4 does not act as a dedicated broken link checker, but it can show where users drop off after landing on problem pages. This is useful when a broken or missing page is still getting traffic from search, emails, social posts, or internal navigation.
Look for pages with unusually high exits, very short engagement, or repeated visits that do not lead to meaningful next steps. A broken link buried in a menu, button, or CTA can create a poor path even when the rest of the page is fine.
GA4 is particularly helpful when you want to understand impact, not just detect the issue. For example, if a product page has been removed and visitors still reach it from an old blog post, you may see traffic landing on a dead end. That insight can guide whether you should restore the page, redirect it, or update the referring content.
For reporting, GA4 is often paired with Looker Studio so teams can track broken-link related patterns over time. Google’s own GA4 platform is a practical place to review those engagement signals.
A practical workflow for using both tools together
The most reliable approach is to combine Search Console and GA4 rather than relying on one tool alone. Search Console helps you identify crawl and index signals, while GA4 helps you understand the user-facing effect.
Use this workflow:
- Find suspicious URLs in Search Console reports, especially non-indexed or error-prone pages.
- Check GA4 for traffic to those pages and whether users are exiting quickly.
- Review the source of the broken link: internal page, navigation, blog post, or external referral.
- Choose the right fix: update the link, add a redirect, restore the page, or remove the link if it no longer adds value.
- Recheck the page after the fix to make sure the issue has been resolved.
This workflow works well for blogs, ecommerce stores, and WordPress sites. For example, an online shop may discover that an old category page still receives visits from product articles. A publisher may find that a removed guide is still linked from related posts. In both cases, the issue is less about “broken links” in the abstract and more about preserving a smooth path through the site.
Broken link checks, crawlers, and other SEO tools
Search Console and GA4 are powerful, but they are not complete broken-link scanners. That is where SEO audit tools, website crawler tools, and SEO Chrome extensions can help. A crawler can scan the whole site and list URLs returning 404s, redirect chains, or internal links pointing to missing pages.
Other useful tool types include:
- PageSpeed Insights and Core Web Vitals tools for checking whether technical problems are affecting performance
- Schema markup tools for confirming structured data on pages that have been updated or redirected
- Rank tracking tools for watching whether important pages recover after fixes
- Backlink checker tools for finding external sites still linking to removed URLs
- Content optimisation tools for updating pages that should replace broken or outdated content
If broken links come from backlinks, it may be worth checking whether the old URL still deserves a redirect. If it has valuable links, replacing it with a relevant live page is usually better than leaving it unresolved. You can also review a guide to backlink building to understand how link quality and site structure work together.
Best practices and common mistakes
A few practical habits make broken-link management much easier:
- Fix internal links before external ones where the site experience is affected most
- Use 301 redirects when a page has a clear replacement
- Update navigation and footer links after site changes
- Review old blog content, category pages, and product pages after migrations
- Check broken links regularly rather than only after a redesign
Common mistakes include redirecting every missing page to the homepage, ignoring links in older content, and relying on one tool without checking the actual page context. A redirect should usually lead to the closest relevant page, not just anywhere on the site.
Also remember that tools support SEO decisions, but they do not replace strategy, content quality, technical implementation, or good user experience. Fixing broken links is valuable, but it works best as part of an ongoing SEO process.
Conclusion
Broken link tools in Google Search Console and GA4 are most useful when they are used together. Search Console helps you detect crawl and index issues, while GA4 shows how those issues affect real users. Combined with crawlers and other SEO tools, they give you a clearer view of where to improve site structure, maintain links, and protect search visibility.
For Backlink Works Insights, the key takeaway is simple: use the data to prioritise fixes that improve both discovery and navigation. That approach is more useful than chasing every minor issue at once, and it fits well into a wider SEO audit, content review, and site maintenance routine.
Frequently Asked Questions
Can Google Search Console find every broken link on my site?
No. It can reveal crawl and indexing problems, but a full broken-link scan usually needs a website crawler as well.
What does GA4 tell me about broken links?
GA4 helps you see how users behave after landing on a problematic page, such as quick exits or poor engagement.
Should I redirect every broken URL?
Not always. Redirect pages only when there is a clear and relevant replacement page. Otherwise, update or remove the link if appropriate.
How often should I check for broken links?
Regular checks are best, especially after content updates, migrations, product changes, or site redesigns.
