What Does “Sitemap.xml Files Have Format Errors” Mean?
When a site audit reports “sitemap.xml files have format errors,” it means that the map of your website, which is intended to help search engines understand and index your site structure, contains syntax or structural issues that prevent it from being properly read and processed by search engines. These errors can hinder the search engine’s ability to crawl and index your site efficiently, potentially affecting your site’s search visibility.
Here are some common reasons for format errors in a sitemap.xml file:
1. Invalid XML Syntax
- Missing opening or closing tags.
- Incorrectly nested elements.
- Use of invalid characters or symbols.
- Incorrect attribute usage or missing required attributes.
2. Incorrect Namespace Declarations
The XML sitemap might be missing the correct namespace declaration in the root <urlset> tag.
3. Improper Use of Tags
Incorrect use of <url>, <loc>, <lastmod>, <changefreq>, and <priority> tags. Tags used in the wrong order or placed outside their parent tags.
4. Malformed URLs
URLs in the <loc> tags are improperly formatted or contain invalid characters.
5. File Encoding Issues
The file might not be encoded in UTF-8, which is required for XML directories.
6. Size Limits Exceeded
The website map exceeds the allowed size limits (50MB uncompressed) or contains more than the allowed number of URLs (50,000 per sitemap).
7. Improper Formatting
Extra whitespace, line breaks, or other formatting issues that can disrupt the XML parsing.
