SEO and digital marketing specialists use various analytical tools. This way, they keep track of how well their company's website performs, its current ranking, and whether it's well-optimized enough to generate organic traffic. These tools are called crawlers, and their primary function is to discover the website's content by following links on your pages and indexing that content.

However, you may stumble upon different crawl errors along the way, and this article will cover some of the most popular ones, together with tips on fixing them.

What is a crawl issue?

Crawlability mistakes occur when a crawling tool can't analyze a website as usual. When this happens, Google or another search engine can’t completely understand the content or structure of the site. This can prevent your pages from being indexed, meaning they won't appear in search results or drive organic traffic to your site.

Most common causes for crawl errors

Google recognizes two main types of crawl errors:site issues and URL issues. If you're dealing with the first type, they might affect your whole website, while the URL-related ones only relate to a particular page on your website.

Speaking of the causes of site crawl errors, the most popular ones include server, robots.txt, and DNS problems. For example, you may stumble upon a website error when a server prevents a page from loading, a search engine can't reach your domain, or it can't retrieve your robots.txt file.

Regarding the URL issues, they may occur because of duplicate content, improper link formatting, broken links, etc. Some of the most well-known types include 404 and soft 404 errors, 403 forbidden errors, and redirect loops.

Even though fixing site errors should be a higher priority, promptly treating any problem is essential. All of the abovementioned problems may cause traffic and credibility decline, poor on-site content quality, and eventually lost customers.

How to fix different types of crawl errors

Now that you know the main types of issues and what can cause them, let's focus on how to fix crawl errors. Below, you'll see a list of tips to solve some of the most common site and URL issues.

Fixing 404 errors

404 errors are among the most widespread crawl issues.

This is one of the most common crawl issues. If you see a 404 error, it means the search engine bot couldn’t locate the link. A 404 error can occur if you change the URL and don't update old links pointing to it, if there are broken links, or when you delete a page without adding a redirect.

Here are some of the tips you can try to fix this type of issue:

  • Remove useless links;
  • Implement 301 redirects for the links you no longer need;
  • Refresh and update old content;
  • Update internal links;
  • Check for broken or improperly formatted links;
  • Detect any site changes and see if any links were affected by them.

Fixing broken links

Broken links affect the organic traffic flow to your website and prevent a page from indexing.

A broken link means there's an error in the URL. Here's what you can do to fix it:

  • Inserting a 301 redirect: this is a highly recommended option for SEO purposes; this way, you'll get rid of a link you no longer have use for — instead, lead your visitors to similar product / service pages and get properly indexed pages;
  • Updating or removing a broken link: if there's a typo in the URL, editing it is the easiest way to deal with the issue; it's also possible to remove a link if you don't need it anymore;
  • If your site contains broken external links, you'll need to either remove it or replace it with an alternative, properly working one.

Fixing robots.txt errors

A sample of a robots.txt file.

Robots.txt errors occur when a search engine can’t access your robots.txt file. This file shows Google and other search engines which pages they can or can’t crawl.

To fix related crawlability mistakes, try adding a sitemap index URL (the main sitemap keeping all of your sitemaps together) to a robots.txt file. This must help crawlers detect and understand your website’s structure easier and faster.
