Google crawling is the process by which the Google search engine discovers and indexes web pages on the internet. Google uses automated software programs, known as Google Bots or spiders, to crawl the web and collect information about web pages. The Googlebot starts by visiting a few web pages, and then follows links on those pages to find new pages to crawl. When the Googlebot crawls a web page, it collects information such as the page’s content, keywords, and links to other pages.
Google crawling is important because it helps Google provide relevant search results to users. By crawling and indexing web pages, Google is able to understand the content of those pages and match them to search queries. To ensure that their websites are discoverable by Google and other search engines, webmasters can use various techniques such as optimizing their website’s structure and content, building high-quality backlinks.
HTTP status codes, network errors, and DNS errors can all affect Google search in different ways.
HTTP status codes are returned by web servers in response to a request from a browser. For example, a 200 status code indicates that a page has loaded successfully, while a 404 status code indicates that the page is not found. When Googlebot crawls a web page and encounters an HTTP status code, it may interpret that code as an error or a signal that the page is not functioning properly. This can negatively affect the page’s ranking in Google search results, as Google aims to provide users with high-quality and reliable content.
Network errors and DNS errors can also impact Google search. Network errors occur when a browser is unable to connect to a server, while DNS errors occur when a domain name cannot be resolved to an IP address. When Googlebot encounters network or DNS errors while crawling a website, it may interpret these errors as a sign that the website is unreliable or not functioning properly. This can also negatively impact the website’s ranking in Google search results.
It’s important for webmasters to monitor their website’s HTTP status codes, network errors, and DNS errors in order to identify and fix any issues that may be affecting their website’s performance in Google search results. Webmasters can use various tools and resources, such as Google Search Console, to track and analyze these errors and make the necessary changes to improve their website’s performance.
HTTP status codes:
HTTP status codes are three-digit numbers returned by web servers to indicate the status of a request made by a browser.
There are five categories of HTTP status codes.
Informational (1xx): These status codes indicate that the request has been received and that the server is continuing to process it.
- Success (2xx): These status codes indicate that the request has been successfully received, understood, and accepted by the server.
- Redirection (3xx): These status codes indicate that the requested resource has been moved or replaced, and the client should take additional action to complete the request.
- Client error (4xx): These status codes indicate that there was an error with the client’s request, such as a missing or invalid parameter.
- Server error (5xx): These status codes indicate that there was an error on the server while processing the request.
Here are some common HTTP status codes:
- 200 OK: The request was successful and the server returned the requested data.
- 301 Permanently Moved: The requested resource has been permanently moved to a new location.
- 404 Not Found: The requested resource could not be seen on the server.
- Internal Server Error 500: The server experienced an unforeseen condition and was unable to fulfill your request.
- 503 Service Unavailable: The server is temporarily unable to process the request due to maintenance or overload.
HTTP status codes are important for web developers and administrators to understand, as they can provide valuable insights into the performance and functionality of their websites.
Soft 404 errors:
A soft 404 error is a type of HTTP status code that is returned by a web server when a requested URL appears to be a valid page, but the server is unable to find any meaningful content on the page. This can occur when a web page returns a “200 OK” status code instead of a “404 Not Found” status code when it should have returned the latter.
Soft 404 errors can be problematic for website owners, as they can negatively impact a website’s search engine rankings. This is because search engines, like Google, may interpret soft 404 errors as an indication that the website contains low-quality or irrelevant content, which can lead to a decrease in organic search traffic.
To avoid soft 404 errors, website owners should ensure that any pages with little or no content return a “404 Not Found” status code, rather than a “200 OK” status code. This can be achieved by configuring the web server to return the appropriate status code for pages that do not exist or have been removed. Additionally, website owners can use Google Search Console or other SEO tools to identify soft 404 errors on their website and take appropriate action to fix them.
Fix soft 404 errors:
Fixing soft 404 errors can help improve your website’s user experience and search engine rankings. Here are some steps you can take to fix soft 404 errors:
- Identify soft 404 errors: Use Google Search Console or other SEO tools to identify soft 404 errors on your website. Look for pages that return a “200 OK” status code but have little or no content.
- Update your web server configuration: Configure your web server to return the appropriate status code (usually a “404 Not Found” status code) for pages that do not exist or have been removed. This will ensure that search engines and users are informed that the page no longer exists, rather than being served low-quality content.
- Redirect the page: If the page has been moved to a new URL, use a 301 redirect to redirect users and search engines to the new URL. This will ensure that users and search engines can find the new location of the page and avoid encountering a soft 404 error.
- Remove the page: If the page is no longer needed, remove it from your website. This will ensure that users and search engines do not encounter the soft 404 error and can find relevant content on your website.
- Improve the content: If the page is needed but has little or no content, improve the content on the page. Add relevant and useful content that provides value to users and search engines.
- Update internal links: Make sure that any internal links on your website that point to the page are updated or removed, depending on whether the page has been redirected or removed.
By taking these steps, you can fix soft 404 errors on your website and improve your website’s user experience and search engine rankings.
The page and content are no longer accessible:
If a page and its content are no longer available, the best course of action is to return a “404 Not Found” status code to inform search engines and users that the page is no longer available. This will help prevent soft 404 errors and ensure that search engines do not index or show the page in search results.
Additionally, you may want to consider implementing a custom 404 error page that provides helpful information to users who encounter a “404 Not Found” error. A custom 404 page can include links to other relevant content on your website or suggestions for other actions that users can take, such as contacting customer support or browsing related content.
If the page and its content have been moved to a new URL, you can implement a 301 redirect from the old URL to the new URL. This will ensure that users and search engines are redirected to the new location of the content and avoid encountering a “404 Not Found” error.
It’s important to regularly monitor your website for broken links or pages that return a “404 Not Found” status code. This can be done using tools like Google Search Console or other SEO tools. By promptly fixing broken links and updating or removing pages that are no longer available, you can improve the user experience and search engine rankings of your website.
The page or content is now somewhere else:
If a page or its content is now located somewhere else on your website, the best way to handle this situation is to implement a 301 redirect from the old URL to the new URL. A 301 redirect is a permanent redirect that informs search engines and users that the content has moved permanently to a new location.
By implementing a 301 redirect, you can ensure that users and search engines are redirected to the new location of the content and avoid encountering a “404 Not Found” error. This can help preserve the search engine rankings and traffic of the original page, as well as ensure that users are able to find the content they are looking for.
To implement a 301 redirect, you will need to update the configuration of your web server or content management system. You can do this by creating a redirect rule that maps the old URL to the new URL.
It’s also a good idea to update any internal links or external links pointing to the old URL to the new URL. This will ensure that users and search engines are able to find the content even if they access it through an old link.
Finally, it’s important to regularly monitor your website for broken links or pages that return a “404 Not Found” status code. This can be done using tools like Google Search Console or other SEO tools. By promptly fixing broken links and updating or removing pages that are no longer available, you can improve the user experience and search engine rankings of your website.
The page and content still exist:
If the page and content still exist on your website but are returning a soft 404 error, there are several steps you can take to fix the issue:
- Check the page content: Check the content of the page to ensure that it is relevant and provides value to users. If the content is thin or low-quality, consider adding more content or improving the quality of the existing content.
- Check the metadata: Check the metadata of the page, including the title tag and meta description, to ensure that they accurately describe the content of the page. This can help improve the relevance and click-through rate of the page in search results.
- Check for broken links: Check for any broken links on the page that may be causing the soft 404 error. Fix any broken links by updating them to point to the correct URLs.
- Check for duplicate content: Check for any duplicate content on the page that may be causing the soft 404 error. Remove any duplicate content to ensure that the page content is unique.
- Check for technical issues: Check for any technical issues that may be causing the soft 404 error, such as incorrect server configuration or URL structure. Fix any technical issues to ensure that the page returns the correct status code.
- Test the page: Test the page to ensure that it returns the correct status code and displays the content correctly. You can use tools like Google Search Console or other SEO tools to test the page and identify any issues.
By taking these steps, you can fix soft 404 errors on your website and improve the user experience and search engine rankings of your website.
Network and DNS errors:
Network and DNS errors can affect Google search in several ways. If your website experiences network or DNS errors, it can lead to slow page load times, broken links, and other issues that can negatively impact the user experience and search engine rankings of your website.
Here are some ways that network and DNS errors can affect Google search:
- Slow page load times: Network errors can cause slow page load times, which can result in a poor user experience and lower search engine rankings. Google takes page speed into account when ranking websites, so it’s important to ensure that your website loads quickly and efficiently.
- Broken links: DNS errors can cause broken links on your website, which can lead to 404 errors and soft 404 errors. This can negatively impact the user experience and search engine rankings of your website.
- Crawling and indexing issues: Network and DNS errors can also prevent Google from crawling and indexing your website properly. If Google is unable to access your website due to network or DNS errors, it may not be able to crawl and index your pages, which can lead to lower search engine rankings.
To avoid these issues, it’s important to monitor your website for network and DNS errors and fix them promptly. You can use tools like Google Search Console or other SEO tools to monitor your website for errors and identify issues that need to be fixed. Additionally, you can work with your web hosting provider to ensure that your website is running efficiently and that any network or DNS issues are resolved quickly.
