What is Sitemap?

A sitemap is essentially a map of your website for search engines. While Googlebot can discover pages by following links, a sitemap provides a direct, organized inventory of all pages you want indexed — especially useful for new sites with limited inbound links, large sites with many pages, sites with complex URL structures, or pages that aren't easily discovered through normal link-following.

XML sitemaps are the standard format for search engines. Each URL entry can include optional metadata: lastmod (when the page was last updated), changefreq (how often it changes), and priority (relative importance among your pages). While Google doesn't guarantee it will honor all metadata, including it is still best practice. Most modern CMS platforms (WordPress, Shopify, Webflow) generate sitemaps automatically — typically accessible at yourdomain.com/sitemap.xml.

Beyond a standard sitemap, specialized sitemaps exist for: image sitemaps (help Google index images), video sitemaps (for video content), and news sitemaps (for publishers who want articles indexed in Google News). For large sites, sitemap index files can split a site into multiple sitemap files, each covering different sections.
