Introduction
Yet, a sitemap is only as good as the URL addresses it contains. If URLs are incorrect or outdated, or any other XML errors occurred, the file won’t serve its purpose correctly.
ToolibeX XML Sitemap Validator helps website owners review their sitemap and ensure that there are no errors. Whether it is a blog, an e-commerce site, or a corporate website, every web owner understands the importance of proper technical SEO, and validating the sitemap is a good place to start.
About the XML Sitemap Validator
XML sitemap validator is a website management tool that allows users to check if a sitemap complies with standard validation rules and can be processed correctly. XML files contain structured data in a standardized format, specifically the tags and the information contained in them.
In a sitemap context, XML format helps define a list of URLs that a website owner wants search engines to know about. Depending on the type of sitemap, it may also contain information about when a particular page was last modified.
A sitemap validator checks the XML file for common errors that affect its ability to be correctly processed. Website owners, SEO specialists, and developers can use an online XML sitemap validator to ensure the file does not contain any issues.
Particularly useful for SEO professionals that regularly perform technical audits, bloggers that publish new articles, and e-commerce websites with thousands of product pages.
XML sitemap validation helps ensure that the document is correctly formatted and does not contain any errors. However, it is important to understand that a valid sitemap is not a guarantee that all the listed URLs will be indexed or that they deserve being indexed.
Why Sitemap Validation is Important for SEO
A sitemap is an important SEO tool that helps search engines find the website’s important pages. It supplements the discovery of new URLs by crawlers, which is especially beneficial for websites with a high number of URLs or complicated navigation structures.
A sitemap helps search engines crawl the website faster and more efficiently, and it can also benefit from a technical SEO audit. However, a valid XML sitemap is not a substitute for high-quality content, clean URL structure, and correct canonicalization.
Discover New and Updated Content
A sitemap helps search engines discover new content and pages that have been updated. Such changes are especially valuable for blogs and other types of content-driven websites but can also be a part of an e-commerce or corporate website.
Maintain Accurate URLs in the Sitemap
The URLs in a sitemap change as the website evolves. Old pages are updated or deleted, new pages are created, and existing URLs are changed for better SEO. Therefore, it is crucial to update the sitemap according to the current state of the website.
Incorrect or outdated URLs in a sitemap can lead to additional errors and complicate website maintenance. XML sitemap validation helps ensure that the file does not have URL-related issues.
Allow Search Engines to Communicate with Your Website
By submitting a sitemap to Google Search Console and other major search engines, website owners can let search engines know about the existence of their website or updates to it.
XML sitemap validation helps ensure that it does not have any errors when doing that. However, search engine bots still decide whether to follow and index the URLs listed in the sitemap.
Help Larger Websites and Websites with Complex Structures
Larger websites and websites with a complex URL structure may use multiple sitemaps for different sections of the website. In that case, a sitemap index should also be created that lists all the sitemaps on the server.
XML sitemap validation helps ensure that these files are valid and do not have any issues.
How the XML Sitemap Validator Works
The XML sitemap validation process generally consists of several steps. First, the validator needs to be pointed to the sitemap URL, which can be found on the website or in the robots.txt file. Then, the tool checks the document for any syntax issues.
Finally, the URLs listed in the sitemap are checked for common errors.
Depending on the particular tool, XML sitemap validation may involve additional checks beyond standard syntax and URL validation. For example, some tools can also check if the server handles the URLs correctly.
1. Find the URL to the Sitemap
The first step in validating a sitemap is to find the URL where it is located. Some websites list their sitemap in a publicly accessible location, such as /sitemap.xml. In that case, the full URL to the sitemap may be constructed by replacing example.com with the website’s domain.
Alternatively, the website’s robots.txt file may list the location of the sitemap. If the user has a Google Search Console account set up for the website, it may also provide a link to the sitemap.
1. Check if the XML Sitemap Has Proper Syntax
A sitemap is an XML document, which means that it should conform to the standard XML syntax and have the correct tags. The exact tags depend on the type of sitemap, but a regular sitemap will generally have a tag, and a sitemap index will use a tag instead. Using an XML sitemap validator tool helps check if the document’s syntax is correct.
1. Check the URLs Listed in the Sitemap
The next step is to ensure that the URLs listed in the sitemap are correct. For the most part, URL validation consists of checking if they are valid URLs that lead to real pages.
In some cases, a valid URL may have incorrect content or be blocked by robots.txt or noindex signals. In that case, a search engine will not follow the URL listed in the sitemap, and the issue will need to be resolved on the page level.
For a regular XML sitemap, the URLs will generally be placed within tags.
1. Look for Additional Issues
Depending on the tool, additional checks beyond basic syntax and URL validation may be performed. For example, some tools can look for issues with URL format that go beyond simple misspellings or incorrect domains.
1. Fix Any Issues Discovered
After the XML sitemap has been validated and issues discovered, the next step is to fix them. That usually involves going into the website administration or the tool that is used to generate the sitemap and modifying the incorrect URLs.
Once the changes have been made, the XML sitemap should be validated again to ensure that all issues have been resolved.
Interpret the Results of XML Sitemap Validation
When using an XML sitemap validator, it is important to understand what the results mean in terms of how to improve the sitemap and, as a result, the website’s SEO.
Proper XML Formatting
A valid XML sitemap is an essential part of any SEO strategy because search engines can read and interpret it. If the document has incorrect syntax, it will generally be rejected by search engines.
It should always be validated to ensure that it conforms to the standard XML syntax.
Valid URLs in the Sitemap
The URLs listed in the sitemap should also be checked for validity. In most cases, the tool used for XML sitemap validation will point out any malformed URLs.
URLs in XML sitemaps should ideally be absolute URLs, meaning that they should include the schema (http or https) and the server name. In contrast, relative URLs only list the location of a URL, such as /guides/.
Access to the Sitemap URL
A sitemap is a regular file on a server, which means that it should be accessible at the specified location. A valid XML document will generally not be accessible if it has the wrong file name or if the server is configured to deny access to it.
Outdated or Invalid Entries in the Sitemap
The purpose of a sitemap is to list the URLs that the webmaster wants search engines to know about. As such, outdated entries or entries that point to URLs that do not exist should be removed from the sitemap.
Additionally, the sitemap should ideally only list URLs that actually want to be discovered by search engines. For that reason, entries that redirect to other URLs, show 404 errors, or are otherwise not intended to be public should also be double-checked.
XML Sitemap Index Issues
Large websites often have multiple sitemaps, each of which lists the URLs for a specific section of the website. In that case, another sitemap, called the sitemap index, should list all the sitemaps on the server. The XML sitemap index validator will highlight any issues with the index file, but if it appears to be valid, the regular sitemaps should also be validated.
XML Sitemap Not Necessarily Valid
A valid XML sitemap is not necessarily a guarantee that the website will appear in search engines. Search engines decide for themselves which websites to index and which ones not to, and they may choose to ignore the sitemap.
XML Sitemap Validation Examples
Example 1: A New Blogger and a Missing Blog Post
A new blogger launches a blog about technology and writes the first article. They publish it on their website, but it does not appear within their sitemap. When they attempt to validate the sitemap, they see several issues with it.
The blogger realizes that their blogging platform does not have a built-in sitemap generator. They use the XML sitemap validation tool to determine the exact issues with their current sitemap file and then fix them.
Example 2: An E-Commerce Website and Several Redirecting URLs
An online store decided to refresh its product line and got rid of several items. They did not update their sitemap after relisting some of the products, and some of the old URLs redirect to the new pages. When they attempt to validate the sitemap, they discover those redirecting URLs.
They decide to review those URLs to ensure that they do not adversely affect their SEO and update their sitemap.
Example 3: Website Migration and Sitemap Redesign
A company decided to migrate its website to a new design for better customer experience and to improve its SEO. However, the new design did not update the old URLs, and the sitemap was still based on the old website structure.
After migrating the website, they validate the sitemap and continue updating the URL redirects and canonical tags to ensure that everything works correctly.
Example 4: Multiple Sitemaps for a Large Website
A website about news and politics utilizes multiple sitemaps to organize its content. They also have a sitemap index file, which designates where the other sitemaps are located. When they attempt to validate the sitemap, several issues are found with the index file. Fixing those issues helps ensure that the main sitemap is also valid.
Best Practices and Recommendations for XML Sitemap Maintenance
Always Use Canonical URLs within a Sitemap
A website should ideally only have one URL for a given page, which minimizes the chances of search engines misunderstanding which URL should appear in search results. As such, only the canonical URLs should be submitted to search engines, and the sitemap should include those URLs.
Keep the Sitemap Updated
A sitemap should be kept up-to-date to reflect the current state of the website. Any changes to the website should also be reflected in the sitemap to avoid issues with crawlers and search engine bots.
Remove Unnecessary URLs from the Sitemap
Any URLs that should not appear in the sitemap, such as those with 404 errors or redirects, should be double-checked. Similarly, URLs that have been moved or changed should also be removed from the old location and added to the new one.
Check XML Sitemap Syntax
The file should also be reviewed for any syntax issues. A simple misspelling of an element can render the entire sitemap invalid and unusable.
Use Absolute URLs in XML Sitemaps
URLs listed in the sitemap should always be absolute URLs. Otherwise, search engines may not be able to follow them correctly.
Check if robots.txt File Contains the Sitemap Location
If the website has a robots.txt file, the sitemap should be listed there. Doing so ensures that search engines can find it.
Submit the Sitemap to Google Search Console
The sitemap should be submitted to Google Search Console to ensure that it appears there correctly and has not been rejected. If it has been rejected, the issue should be resolved before resubmitting it.
Validate the Sitemap After Major Changes to the Website
Whenever there are significant changes to the website or its URL structure, the sitemap should be validated to ensure that there are no issues.
URLs within a Sitemap Should Ideally Follow the Same Pattern
A sitemap should ideally list the same pattern of URLs. Having a mixture of different URL patterns increases the chances of errors and should generally be avoided.
Become Familiar with the Limitations of Large Sitemaps
For smaller websites, creating and maintaining a sitemap is generally straightforward. However, larger websites may require additional considerations, such as limiting the number of URLs listed in a single file.
Follow Recommendations Provided by an XML Sitemap Validator
Every website is different, and there may be issues that are not covered by a standard XML sitemap validator. In those cases, recommendations provided by an online tool should be reviewed.
