XML Sitemaps: Best Practices for Helping Search Engines Crawl Your Site

An XML sitemap is a file that lists all the important pages on your website and provides metadata about each URL. It helps search engines discover, crawl, and index your content efficiently. While not strictly required, sitemaps are a fundamental technical SEO best practice.

Sitemap Structure

A well-structured sitemap lists each URL with optional metadata including last modified date, change frequency, and priority. For large sites, a sitemap index file references multiple sub-sitemaps organized by content type or section. Keep individual sitemaps under 50,000 URLs and 50MB.

What to Include

Include all pages that provide unique, valuable content and that you want appearing in search results. This typically includes your homepage, service pages, blog posts, location pages, and key landing pages. Only include pages that return 200 status codes and are not blocked by robots.txt or noindex tags.

What to Exclude

Do not include URLs that redirect, return errors, are blocked by robots.txt, have noindex tags, or contain duplicate content. Including these URLs wastes crawl budget and sends confusing signals to search engines about which pages matter on your site.

Dynamic Sitemap Generation

For websites with frequently changing content, dynamically generated sitemaps automatically update as content is added, modified, or removed. Most CMS platforms and frameworks support automatic sitemap generation. This ensures your sitemap always accurately reflects your current site structure.

Sitemap Monitoring

After submission, monitor your sitemap in Google Search Console. Check that submitted URLs match the number of indexed URLs. Large discrepancies indicate potential issues with crawlability, indexability, or content quality. Regular monitoring catches problems before they significantly impact your search visibility.
