Frequently Asked Questions
An XML Sitemap Validator is a specialized tool that parses your sitemap files and checks them against the official sitemap schema guidelines and search engine recommendations. It checks for XML syntax formatting errors, relative URL bugs, invalid change frequencies, incorrect priority values, and duplicates, helping you fix issues before submission.
According to Google and the official Sitemap Protocol, a single sitemap file must not exceed 50,000 URLs and its uncompressed file size must be under 50 megabytes (50MB). If your sitemap exceeds either of these limits, you must split it into multiple sitemaps and list them in a sitemap index file.
A URL Sitemap (wrapped in a <urlset> tag) contains the actual list of page links on your website along with search instructions (lastmod, priority). A Sitemap Index (wrapped in a <sitemapindex> tag) acts as a directory that lists other sitemap URLs. Sitemap Indexes are used to group multiple sitemaps for large websites.
No. Fragment identifiers (like #section) are strictly disallowed by search engines in sitemap URLs. Crawlers ignore page fragments during crawling because they represent segments of a single document rather than unique target crawl URLs. Including them is parsed as an error.
There are two primary methods: 1) Add a directive pointing to your absolute sitemap URL inside your robots.txt file (e.g. Sitemap: https://example.com/sitemap.xml). 2) Submit your sitemap path directly inside search consoles, such as Google Search Console or Bing Webmaster Tools.
