What is a sitemap and how does it help with SEO?

A sitemap is a file listing all pages on your website, helping search engines discover and crawl pages. XML sitemaps are for search engines, while HTML sitemaps help users navigate. Sitemaps help search engines find all pages, especially on large sites or sites with complex navigation. They're especially important for new sites with few external links. Submit sitemaps to Google Search Console. Keep sitemaps updated as you add pages. Include only indexable pages. Sitemaps don't guarantee indexing but help search engines discover content. Many technical SEO consultants help create and submit proper sitemaps. For large sites, sitemaps are essential for ensuring all pages are discovered.
