Why Sitemaps Matter for SEO
A properly formatted sitemap helps search engines discover all the important pages on your website. It's especially valuable for new websites, sites with deep page hierarchies, or pages that aren't well linked internally. Search engines use sitemaps to understand your site structure and prioritize crawling.
Best Practices for Sitemaps
Keep your sitemap updated whenever you add or remove pages. Only include canonical URLs that return 200 status codes. Split large sitemaps into multiple files using a sitemap index. Submit your sitemap to Google Search Console and Bing Webmaster Tools for faster indexing.

The tool will fetch your sitemap, parse the XML, and display detailed validation results including any errors, warnings, and informational messages. You'll see statistics about your sitemap, a preview of the URLs it contains, and specific guidance on how to fix any issues found.
FAQ
What is a sitemap.xml file?
A sitemap.xml is an XML file that lists all the important URLs on your website. It helps search engines like Google, Bing, and others discover and crawl your pages more efficiently. Sitemaps can include metadata about each URL such as when it was last updated, how often it changes, and its relative priority.
Why should I validate my sitemap?
Validating your sitemap ensures that search engines can properly read and process it. Invalid sitemaps may be rejected by search engines, meaning your pages might not get indexed correctly. Common issues include malformed XML, invalid URLs, missing required tags, and exceeding size limits.
What is the maximum size for a sitemap?
According to the sitemap protocol, a sitemap file must be no larger than 50MB (uncompressed) and can contain a maximum of 50,000 URLs. If your site has more URLs, you should create multiple sitemaps and reference them using a sitemap index file.
What is a sitemap index?
A sitemap index is an XML file that references multiple sitemap files. It allows you to organize large sites by splitting URLs across several sitemaps. Search engines will process all the individual sitemaps listed in the index file.
What tags are required in a sitemap?
The only required tag for each URL entry is <loc>, which contains the absolute URL of the page. Optional tags include <lastmod> (last modification date), <changefreq> (how often the page changes), and <priority> (relative importance from 0.0 to 1.0).
What date format should I use for lastmod?
The <lastmod> tag should use the W3C Datetime format. The simplest form is YYYY-MM-DD (e.g., 2024-01-15). You can also include time with timezone: 2024-01-15T09:30:00+00:00. Always use the actual last modification date of the content.
Does Google use priority and changefreq?
Google has stated that they largely ignore the <priority> and <changefreq> tags as they rely on their own algorithms to determine crawl frequency and page importance. However, other search engines may still use these values, so including them can still be beneficial.
How do I submit my sitemap to search engines?
You can submit your sitemap through each search engine's webmaster tools: Google Search Console, Bing Webmaster Tools, etc. You can also add a Sitemap directive in your robots.txt file (Sitemap: https://example.com/sitemap.xml) to help search engines discover it automatically.
Should my sitemap use HTTPS?
Yes, your sitemap should be served over HTTPS for security and better SEO. Additionally, all URLs within your sitemap should use the same protocol (HTTP or HTTPS) as the sitemap itself. Mixing protocols can cause indexing issues.
How can I track if search engines are reading my sitemap?
Swetrix analytics can help you monitor bot traffic and crawl activity on your website. You can see when search engine bots visit your pages, track indexing progress, and identify any crawling issues—all while respecting user privacy and GDPR compliance.
