Understanding and Resolving Crawl Errors

Understanding and Resolving Crawl Errors

Have you ever come across the term “crawl errors” while working on your website’s SEO? If so, you’re in the right place. In this article, we’ll dive into the world of crawl errors, understand their importance, and learn how to identify and resolve them effectively. So let’s get started!

What are crawl errors?

Crawl errors, also known as crawl issues or HTTP errors, occur when search engine bots encounter difficulties while crawling and indexing web pages on your site. These errors can prevent search engines from properly understanding and ranking your content. It’s crucial to address these issues promptly to maintain a healthy website performance and maximize your SEO efforts.

Importance of Understanding and Resolving Crawl Errors

Resolving crawl errors is essential for maintaining a well-optimized website. When search engine bots encounter crawl errors, it can negatively impact your site’s visibility, search engine rankings, and organic traffic. By understanding and resolving these errors, you can ensure that your website is easily accessible and comprehensible to search engines, resulting in better search engine performance.

Common types of crawl errors

Let’s explore some of the most common types of crawl errors and understand their implications.

404 errors

One of the most prevalent crawl errors is the 404 error, commonly known as the “page not found” error. It occurs when a web page is missing or has been removed without proper redirection. Search engine bots may encounter 404 errors when they attempt to crawl a page that no longer exists. These errors can harm user experience and lead to a negative impact on your search engine rankings.

500 errors

A 500 error, also referred to as a server error, indicates an internal server problem that prevents the successful retrieval of a web page. When search engine bots come across 500 errors, they are unable to access and index the affected pages. It’s crucial to address server errors promptly to ensure that your website remains accessible and properly indexed.

301 and 302 redirects

Redirects are used to direct users and search engines from one URL to another. However, if not implemented correctly, they can lead to crawl errors. A 301 redirect is a permanent redirect, while a 302 redirect is temporary. Improper redirects can confuse search engine bots, resulting in crawl errors and negatively impacting your SEO efforts.

Soft 404 errors

Soft 404 errors occur when a page returns a “not found” response but does not provide a proper 404 status code. Search engines may treat these soft 404 errors as actual content, leading to indexing issues and potential duplicate content problems. It’s important to handle soft 404 errors appropriately to ensure search engines understand the correct status of your web pages.

Access denied errors

Access denied errors occur when search engine bots are restricted from accessing specific web pages due to improper server configurations or access permissions. These errors can prevent search engines from crawling and indexing critical content on your website, resulting in decreased visibility and organic traffic.

Impact of crawl errors on SEO

Understanding the impact of crawl errors on your SEO efforts is crucial for prioritizing their resolution.

Negative effects on search engine rankings

When crawl errors occur, search engines may struggle to index your web pages properly. As a result, your website’s visibility in search engine result pages (SERPs) may be negatively affected, leading to lower rankings. By identifying and resolving crawl errors, you can improve your chances of achieving higher search engine rankings.

Decreased visibility and organic traffic

Crawl errors can lead to decreased visibility in search results, which directly impacts organic traffic. When search engines encounter crawl errors, they may choose to devalue or exclude affected pages from their index. This can result in a significant loss of organic traffic and potential customers. Resolving crawl errors is crucial for ensuring your website is fully accessible to search engine bots, allowing them to index your content effectively.

Identifying crawl errors

To effectively resolve crawl errors, you need to identify them first. Here are a couple of methods to help you with this process.

Google Search Console

Google Search Console is a powerful tool that provides valuable insights into your website’s performance in search results. It offers a dedicated section for crawl errors, where you can find detailed reports on the errors encountered by Google while crawling your website. Utilizing Google Search Console’s data can help you identify and prioritize the resolution of crawl errors efficiently.

Crawl error reports

Several SEO tools provide crawl error reports, allowing you to identify issues beyond Google Search Console. These reports can help you uncover crawl errors that may have been missed or provide additional insights into the root causes of the errors. By leveraging these reports, you can gain a comprehensive understanding of the crawl errors affecting your website.

Resolving crawl errors

Once you’ve identified crawl errors, it’s crucial to take appropriate actions to resolve them. Let’s explore some common crawl errors and the steps to address them effectively.

Fixing 404 errors

To fix 404 errors, start by identifying the pages with broken links or incorrect URLs. Update or redirect these URLs to relevant pages, ensuring a seamless user experience and preserving link equity. Additionally, create custom 404 error pages to guide users and search engine bots back to relevant content.

Resolving server errors

When encountering server errors, investigate the root causes of the problem. Check your server logs for any reported issues and consult with your hosting provider if necessary. Addressing server errors promptly can ensure that search engine bots can access and index your web pages without any hindrance.

Correcting redirect issues

If you encounter redirect issues, review your redirects and ensure they are correctly implemented. Replace temporary redirects (302) with permanent redirects (301) when appropriate. Test the redirects to ensure they function as intended, guiding users and search engine bots to the correct destination URLs.

Handling soft 404 errors

To handle soft 404 errors, ensure that your web server returns the appropriate 404 status code when a page is not found. Customize your error pages to provide relevant information and alternative content suggestions to users and search engines.

Resolving access-denied errors

When dealing with access denied errors, review your server configurations and access permissions. Ensure that search engine bots have the necessary access to crawl and index your web pages. Consult with your web hosting provider or system administrator to resolve any access restrictions.

Best practices for preventing crawl errors

Prevention is always better than cure. By following these best practices, you can minimize the occurrence of crawl errors and maintain a healthy website.

Regularly monitoring crawl error reports

Stay proactive by regularly monitoring crawl error reports provided by search engines and SEO tools. By promptly addressing emerging crawl errors, you can mitigate their impact on your website’s SEO performance.

Properly redirecting URLs

When making changes to your website’s URL structure or removing pages, ensure that you implement proper redirects. Redirect users and search engine bots to the most relevant and equivalent URLs. This helps maintain link equity and ensures that search engines can continue to index your content seamlessly.

Maintaining a clean website structure

Organize your website’s structure in a logical and user-friendly manner. Ensure that your internal linking is well-structured, allowing search engine bots to navigate and crawl your site efficiently. A clean website structure reduces the likelihood of encountering crawl errors and improves overall SEO performance.

Implementing canonical tags

Canonical tags are HTML elements that indicate the preferred version of a web page when multiple versions exist. Implementing canonical tags can help prevent duplicate content issues and ensure that search engines index the correct version of your pages. This helps to avoid crawl errors caused by indexing redundant or conflicting content.


Understanding and resolving crawl errors are crucial steps in maintaining a healthy and well-optimized website. By proactively identifying and addressing crawl errors, you can improve your search engine rankings, increase organic traffic, and provide a seamless user experience. Remember to regularly monitor crawl error reports, fix broken links, resolve server errors, and optimize your website’s structure to minimize the occurrence of crawl errors.
