Broken links (404 errors) can severely impact your website’s SEO, user experience, and crawlability. If a user or search engine crawler encounters a broken link, it leads to frustration, lost traffic, and potential ranking penalties. That’s why it's essential to regularly check for broken links and fix them promptly.
Here's why and how you should regularly check for broken links on your site:
Why Regularly Checking for Broken Links Is Important
- Improved User Experience:
- Broken links frustrate users, especially if they land on a page that doesn't exist. This can lead to high bounce rates, which can negatively impact your site's engagement and conversion rates.
- Better SEO:
- Search engines like Google use crawling bots to discover and index your content. Broken links prevent these bots from efficiently crawling your site, potentially leading to your content not being indexed properly.
- 404 errors can send signals to search engines that your website is outdated or poorly maintained, which may affect your ranking.
- Improved Crawl Efficiency:
- If Googlebot encounters many 404 errors, it may reduce the crawl frequency or limit the crawling of your website.
- Ensuring there are minimal broken links means Googlebot can crawl more pages, allowing more of your content to be indexed.
- Internal Link Equity Preservation:
- Broken internal links waste valuable link equity. Pages that are not linked properly or return 404 errors may not pass on link equity to other important pages on your website.
- Preventing Link Rot:
- Link rot occurs when links to external or internal pages become broken over time. Regular checks help to prevent your site from becoming outdated.
How Often Should You Check for Broken Links?
- New Websites: If your website is relatively new or is constantly being updated, you should check for broken links at least once a month.
- Established Websites: For mature websites, you should aim to check quarterly, though checking every 2-3 months is a good practice.
- High-traffic Sites: For larger websites with frequent content updates (like blogs, e-commerce sites, or news sites), monthly checks or even weekly checks might be necessary to ensure broken links don't accumulate.
Tools to Help You Regularly Check for Broken Links
There are several tools available to automate or simplify the process of checking for broken links. You can choose the one that best fits your website's needs.

5. Broken Link Checker (WordPress Plugin)

Best Practices for Managing Broken Links
- Set Up Redirects for Moved Pages:
- If you remove or move a page, implement a 301 redirect to send users and search engines to the new page.
- Remove or Replace Broken External Links:
- If you're linking to an external resource that no longer exists, either remove the link or replace it with a relevant working link.
- Regularly Update Your Content:
- Content updates (e.g., blog posts, product pages) often result in broken links. By keeping your content fresh, you ensure that broken links are caught early.
- Implement a “404” Page:
- Have a custom 404 error page that guides users back to working pages (like your homepage or popular content) instead of leaving them on a dead-end page.
- Monitor and Track Link Health:
- Keep a broken link monitoring tool running on your site to catch new issues as they arise.
