Fixing Crawl Errors & Broken Links
Fixing crawl errors & broken links requires a systematic approach to identify and repair connection issues throughout your website.
Internal Link Audit
Regularly audit your internal links to prevent crawl errors:

- Identify broken internal links
- Update or remove problematic links
- Implement proper URL structure
External Link Management

Managing Googlebot Crawl Rate and Crawl-Delay
Sometimes you need to control how search engines crawl your site. Here’s how to manage the Googlebot crawl rate and implement crawl-delay settings.
Understanding Crawl Budget
Every website has a crawl budget – the number of pages Google will crawl in a given timeframe. Poor crawl error management wastes this budget on broken pages instead of valuable content.
Using Robots.txt Crawl-Delay
The robots.txt crawl-delay directive helps control crawling speed:
User-agent: *
Crawl-delay: 10
This tells crawlers to wait 10 seconds between requests. Use this carefully, as excessive delays can hurt indexing.
Change Googlebot Crawl Rate
You cannot directly control Google’s crawl rate, but you can influence it:
- Improve site speed and server response times
- Fix crawl errors promptly
- Maintain consistent website availability
- Use proper XML sitemaps
- Optimize internal linking structure
How to Fix Crawl Errors Impacting Search Rankings

FAQs
What exactly are crawl errors?
Crawl errors happen when search engines like Google try to visit your website pages but can’t access them for some reason. These errors prevent search engines from reading and indexing your content, which means your pages won’t show up in search results.
How do I know if my website has crawl errors?
You can check for crawl errors using Google Search Console (it’s free). Just log into your account, go to the Coverage section, and you’ll see all the errors Google found while trying to crawl your site. You can also use tools like Screaming Frog or check your server logs.
What are the most common types of crawl errors I should watch out for?
The main crawl errors include 404 errors (page not found), 500 errors (server problems), redirect chains, blocked pages in robots.txt, and timeout issues. 404s are probably the most common – they happen when you delete or move pages without setting up proper redirects.
Do crawl errors really hurt my search rankings?
Yes, they can seriously damage your rankings. When search engines can’t crawl your pages, those pages won’t get indexed or ranked. Plus, too many crawl errors make your site look poorly maintained, which search engines don’t like. It’s like having broken links everywhere – it creates a bad user experience.
How do I fix 404 errors on my website?
For 404 errors, you have two main options. If the page still matters, restore it or create new content for that URL. If the page is no longer needed, set up a 301 redirect to send visitors to a relevant page instead. Don’t just leave broken links hanging around.
What should I do about server errors (5xx errors)?
Server errors mean there’s a problem with your hosting or website setup. Check with your web host first – they might be having server issues. Also look at your website’s plugins, themes, or recent changes that might be causing conflicts. Sometimes clearing your site’s cache helps too.
How often should I check for crawl errors?
Check your Google Search Console at least once a week. Set up email notifications so Google alerts you when new errors pop up. The sooner you catch and fix crawl errors, the less damage they’ll do to your search rankings.
Can my robots.txt file cause crawl errors?
Absolutely. If you accidentally block important pages in your robots.txt file, search engines can’t crawl them. Double-check your robots.txt file (usually found at yoursite.com/robots.txt) and make sure you’re not blocking pages you actually want indexed.
What’s the difference between soft 404s and regular 404s?
Regular 404s properly tell search engines “this page doesn’t exist.” Soft 404s are tricky – they look like they’re working but actually show error content while returning a 200 status code. Search engines get confused by soft 404s, so fix them by either returning proper 404 codes or creating real content.
How long does it take for Google to recognize that I’ve fixed crawl errors?
Google usually notices fixes within a few days to a couple weeks, depending on how often they crawl your site. You can speed things up by using the URL inspection tool in Google Search Console to request re-crawling of specific pages you’ve fixed. Just be patient – good things take time.
