Fixing Crawl Errors & Broken Links
One of the most critical aspects of maintaining a healthy website is ensuring that it’s easily crawlable by search engines. Crawl errors and broken links are common issues that can negatively impact your site's SEO performance, user experience, and overall functionality. In this article, we’ll explore what crawl errors and broken links are, how to identify them, and how to fix them to ensure your site runs smoothly.
1. What Are Crawl Errors?
Crawl errors occur when a search engine’s bot (like Googlebot) attempts to access a page on your website but encounters a problem that prevents it from properly indexing the page. These errors can arise for several reasons, including issues with server configuration, incorrect URLs, or changes to the website’s structure.
Crawl errors can be categorized into two main types:
1.1. 404 Errors (Page Not Found)
This type of error occurs when a page cannot be found at the specified URL. This typically happens when the page has been deleted or the URL has been changed without proper redirection.
1.2. Server Errors (5xx)
These errors occur when the server is temporarily or permanently unable to process the request. Common server errors include 500 (Internal Server Error) and 502 (Bad Gateway). These can be caused by issues like server downtime or misconfigurations.
1.3. DNS Errors
Domain Name System (DNS) errors happen when the search engine’s bot is unable to resolve the website's domain to the correct IP address. This can occur if there are issues with the domain name registration or DNS settings.
2. Why Crawl Errors Matter
Crawl errors can have a significant impact on your SEO efforts:
Indexing Issues: If Google or other search engines cannot crawl and index your pages, they won’t appear in search results. This directly impacts your organic traffic and visibility.
User Experience: Broken pages or server issues can lead to a poor user experience, driving visitors away. This can result in higher bounce rates and lower engagement.
Loss of Link Equity: If external sites are linking to a page that has a crawl error, that link equity (the SEO value of the backlink) will be lost. This can harm the ranking potential of your site.
3. What Are Broken Links?
Broken links, also known as dead links or 404 links, occur when a hyperlink points to a page or resource that no longer exists, or the link itself is incorrect. Broken links can be internal (linking to another page on your site) or external (linking to an external site).
3.1. Types of Broken Links
Internal Broken Links: These are links that point to non-existent or deleted pages within your website. They can confuse search engine bots and frustrate users.
External Broken Links: These are links pointing to external websites that no longer exist or have been moved. External broken links can reduce the perceived authority of your site and negatively affect your SEO.
4. Why Fixing Broken Links is Important
Broken links have several negative consequences:
SEO Impact: Broken internal links can prevent search engines from crawling and indexing your content properly, negatively affecting your site's rankings. External broken links can reduce the link equity passed from other sites, affecting your site's authority.
User Experience: Clicking on a broken link results in a frustrating experience for users. This can cause them to leave your website, increasing bounce rates and decreasing engagement.
Trust & Credibility: Having a website filled with broken links can make your site appear outdated, unprofessional, and unreliable, diminishing trust with both users and search engines.
5. How to Identify Crawl Errors & Broken Links
5.1. Using Google Search Console
Google Search Console is one of the most valuable tools for identifying crawl errors. It provides detailed reports on crawl issues that Googlebot encounters while indexing your site. To check for crawl errors in Google Search Console:
Go to the Coverage report.
Review the Error tab to identify pages that have crawl issues.
Google Search Console will show you specific errors like 404, 500, and other issues, along with details about the affected pages.
5.2. Using Site Crawling Tools
In addition to Google Search Console, tools like Screaming Frog, Ahrefs, SEMrush, and Sitebulb allow you to crawl your website and identify both crawl errors and broken links. These tools can help you locate 404 errors, server errors, and broken links across your site.
5.3. Manually Checking Links
You can also manually check for broken links by visiting key pages of your website and ensuring that all links work correctly. However, this can be time-consuming for larger websites. Automated crawling tools are much more efficient for this task.
6. How to Fix Crawl Errors
Once you've identified crawl errors, it's essential to fix them promptly to maintain your SEO health and user experience. Here’s how to address some common types of crawl errors:
6.1. Fixing 404 Errors
Redirect Old URLs: If the page has been moved, implement a 301 redirect from the old URL to the new one. This will pass any link equity from the old page to the new one.
Restore the Missing Page: If the page was mistakenly deleted, restoring it or recreating it with relevant content can resolve the issue.
Update Internal Links: If the page has been permanently removed, update internal links that previously pointed to it to point to relevant content instead.
6.2. Fixing 5xx Server Errors
Investigate Server Issues: Server errors often occur due to hosting issues. Check with your hosting provider to resolve any server outages or misconfigurations.
Increase Server Resources: If your site experiences high traffic, you may need to scale your server resources to handle the load and prevent server errors.
6.3. Fixing DNS Errors
Check DNS Settings: If you encounter DNS errors, verify your domain’s DNS settings to ensure they are correctly configured. You may need to contact your hosting provider for assistance.
7. How to Fix Broken Links
Fixing broken links can be a multi-step process, but it’s essential for maintaining a healthy website:
7.1. Update Internal Broken Links
For internal broken links, update them to point to live, relevant pages on your website. This can often be done manually through your content management system (CMS) or using a tool like Screaming Frog to identify all internal broken links at once.
7.2. Fix External Broken Links
For external broken links, you have a few options:
Replace the Link: If the external page has been moved or deleted, try to find a relevant, live page to link to instead.
Remove the Link: If the external resource is no longer available and there’s no relevant replacement, consider removing the link altogether.
Reach Out to Webmasters: If the external link is important, you can contact the site owner or webmaster and ask them to restore the page or provide a working link.
7.3. Use 301 Redirects for Moved Pages
If external sites are linking to a page you’ve moved, implementing 301 redirects from the old URL to the new one will preserve the link equity and prevent users from landing on a 404 page.
