Free XML Sitemap Generator

An XML sitemap is a structured file that tells search engines about the pages on your website. It lists URLs along with metadata including when each page was last modified, how often it changes, and how important it is relative to other pages. Major search engines including Google, Bing, and Yahoo all use sitemaps to improve their crawling efficiency.

The XML sitemap protocol (sitemaps.org) was jointly developed by Google, Yahoo, and Microsoft in 2006. Today, it remains the standard way to communicate your site structure to search engines. A well-maintained sitemap ensures that all your important content is discovered and indexed, even pages that might be difficult to reach through normal crawling.

While search engines can discover pages by following links, sitemaps provide a direct, comprehensive list of every page you want indexed. This is especially important for new websites that don't have many backlinks, large sites where some pages may be several clicks deep, and sites that add or change content frequently.

Google Search Console uses your sitemap to track how many of your pages are indexed, identify crawl errors, and report on your site's overall health. Without a sitemap, you're relying entirely on Google's crawler to find all your pages through links — which can miss orphaned pages or take weeks to discover new content.

A valid XML sitemap starts with an XML declaration and a urlset element that references the sitemap namespace. Inside the urlset, each page is represented by a url element containing loc (the URL), lastmod (last modification date), changefreq (how often the page changes), and priority (relative importance from 0.0 to 1.0).

Only the loc element is required — lastmod, changefreq, and priority are optional but recommended. The lastmod date should reflect actual content changes, not just when the page was regenerated. Using accurate metadata helps search engines allocate their crawl budget more efficiently.
